The US tractor tire market was valued at $798.26 million in 2023 and is projected to reach $959.81 million by 2029, a 3.1% compound annual growth rate, according to ResearchAndMarkets. Tractor tires account for 56.73% of the broader agricultural tire market, with the remainder split across harvester, sprayer, and other implement tires. Separately, the US agricultural biologicals market — a distinct product category from tires, covering biopesticides, biostimulants, and biofertilizers — was valued at $3.47 billion in 2025 and is forecast to grow at 11.33% CAGR through 2034, per Expert Market Research.

Those two figures anchor this article: one for readers tracking agricultural tire market size and share, one for readers tracking agricultural biologicals market size. Below, both get broken down with named sources, and a durable method for checking either figure again next quarter or next year.

US Agricultural Tires Market Size: The Numbers Behind the Headline

Start with the number that actually has a named source. ResearchAndMarkets’ United States Tractor Tire Market report puts the tractor tire segment — the largest single slice of the agricultural tire market — at $798.26 million in 2023, rising to a projected $959.81 million by 2029. That’s a 3.1% CAGR over the six-year window. Tractor sales themselves grew 2.5% year-over-year in 2024, according to Arizton’s tractor tire market coverage, which is the closest proxy available for underlying replacement-tire demand since public agencies don’t publish agricultural tire unit sales.

That last point matters for anyone trying to size this market precisely: agricultural tire unit volume (how many tires are actually sold each year in the US) is not published in government data. The dollar figures above come from market research firms compiling manufacturer and distributor data, not from a census. If you need unit-level numbers for a specific tire category, the research brief for this article flags that pricing by tire type (radial vs. bias) exists only inside proprietary manufacturer reports — there’s no public substitute.

What IS public and checkable: the machinery those tires go on. USDA NASS QuickStats tracks farm machinery inventory — tractors, combines, and other equipment — by year and state, and the USDA NASS Census of Agriculture (conducted every five years, most recently 2022) publishes machinery inventory counts in Table 45. Neither directly counts tires, but both are the closest thing to a ground-truth check on how many machines are out there needing tires, and both update on a known schedule you can bookmark.

Why This Market Doesn’t Have a Single “Global” Number Worth Repeating

A lot of agricultural tire content online cites a single global market-size figure with no visible source. That’s a symptom, not a fact: agricultural tire pricing and volume differ enormously by region, tire class, and OEM vs. aftermarket channel, and no public agency aggregates them into one clean global total. The only defensible approach for a US-focused reader is the one used here — cite the segment (tractor tires), cite the geography (United States), cite the source (ResearchAndMarkets), and cite the year range (2023–2029). If another source gives you a bigger, rounder global number with no link attached, treat it as unverifiable rather than authoritative.

Agricultural Tires Market Share by Segment

Within the US agricultural tire market, tractor tires hold the largest single share: 56.73% as of 2024, per market research compiled by Verified Market Research’s US agricultural tires coverage. That leaves 43.27% split across harvester tires, sprayer tires, and tires for tillers, trailers, and other implements — though the research available for this article doesn’t break that remainder into named sub-percentages with a citable source, so this piece won’t invent a split that isn’t published.

If you need a finer breakdown than “tractors vs. everything else,” the path is to go to a paid market research report directly (ResearchAndMarkets and Verified Market Research both sell segment-level breakdowns) or to cross-reference USDA NASS machinery inventory by equipment type as a rough proxy for relative fleet size across tractors, combines, and sprayers in your region.

What Drives Tractor Tires’ Dominant Share

• Fleet size. Tractors are the single most numerous powered implement on most US farms, and every tractor needs a matched set of tires — front and rear, often in different sizes.
• Replacement cycle. Tractor tires see more annual operating hours across more terrain types (tillage, planting, spraying support, hauling) than a combine or sprayer that runs seasonally, which shortens replacement intervals relative to hours of use.
• Radial adoption. The shift from bias-ply to radial tractor tires — which offer better traction, longer tread life, and reduced soil compaction — has been a multi-year trend in North America and is one of the few qualitative trends in this space with clear industry consensus, even where the brief doesn’t have a dollar figure attached to the radial share specifically.

Agricultural Tires Market Trends Driving the 3.1% CAGR

The 3.1% CAGR ResearchAndMarkets projects for the US tractor tire market between 2023 and 2029 isn’t driven by one factor. Three trends recur across the sources available for this piece:

1. Steady tractor sales growth. Arizton reports 2.5% year-over-year growth in US tractor sales in 2024. New tractors need new tires (OEM demand), and the growing installed base needs replacement tires on a rolling basis (aftermarket demand) — both channels feed the tire market independently of each other.
2. Radial conversion. Farms replacing aging bias-ply tires with radials pay a premium per tire but get longer tread life and better fuel economy, which supports higher per-unit revenue even where unit volume growth is flat.
3. Precision agriculture compatibility. As more US operations adopt guidance systems and controlled-traffic farming, tire choice increasingly has to match row spacing and minimize soil compaction in defined traffic lanes — a design constraint that pushes farms toward newer, purpose-built tire lines rather than generic replacements.

None of the sources available here publish a specific dollar or percentage figure for “how much of the 3.1% CAGR is radial conversion versus new tractor sales versus precision-ag-driven replacement.” That breakdown, if it exists, sits inside the same proprietary manufacturer reports that also withhold radial-vs-bias pricing. Treat any article that assigns precise percentages to each driver without a source as a guess dressed up as data.

For farms managing tire wear alongside soil health goals, tracking field-level conditions matters as much as tire spec. Farmonaut Carbon Footprinting Solutions uses satellite monitoring to help operations connect field practices — including traffic patterns that affect both soil compaction and tire wear — to measurable sustainability outcomes.

Agricultural Biologicals Market Size: A Separate Category, Same Farm

Agricultural biologicals — biopesticides, biostimulants, and biofertilizers derived from natural organisms rather than synthesized chemicals — are a distinct market from tires, but the same US farms buy both categories, which is why this figure gets asked about alongside tire market data. The US agricultural biologicals market was valued at $3.47 billion in 2025 and is projected to reach $13.7 billion by 2034, a CAGR of 11.33% over 2026–2034, according to Expert Market Research’s United States Agricultural Biologicals Market report.

Zooming into one biologicals subcategory: the US biopesticides market specifically was $2.69 billion in 2025, per Mordor Intelligence, and North America’s biopesticides market (US, Canada, Mexico combined) is projected to grow from its current base to $5.41 billion by 2031 at a 12.38% CAGR for 2026–2031. Biopesticides sit inside the larger US pesticide market, which PS Market Research values at $21.4 billion in 2024 — 80% of that is still synthetic pesticides, with biologicals making up the remaining 20%. PS Market Research projects the total US pesticide market (synthetic plus biological) will reach $29.9 billion by 2032, a 4.5% CAGR for 2025–2032.

The gap between biologicals’ 11.33% CAGR and the total pesticide market’s 4.5% CAGR is the real story here: biologicals are growing more than twice as fast as the pesticide category they sit partly inside, which is consistent with the 80/20 synthetic-to-biological split narrowing over time rather than staying fixed. None of the sources reviewed for this article publish USDA or USDA ERS forecasts for biologicals adoption specifically — NASS and ERS don’t track this as a distinct market category, so every growth figure above comes from private market research firms, not government data. That’s worth knowing before citing these numbers as if they carried USDA’s authority.

Why Biologicals and Tires Share a Search Page (And Why This Article Covers Both)

Readers searching “agricultural biologicals market size” and readers searching “agricultural tires market size” are rarely the same person mid-session, but they’re often the same person over a season: an operations manager or agronomy consultant sizing multiple input-cost categories for budget planning. That’s the only reason both belong on one page — not because the products relate technically, but because the research task (find a credible US market-size figure with a real source) is identical.

Tire Cost-Per-Acre-Year Calculator

Use your own fleet numbers to estimate annual tire cost per acre — a figure the market-size reports above don’t calculate for you, because it depends entirely on your equipment, acreage, and tire life, not on national totals.

Assumptions: Divides total fleet replacement cost evenly across expected tire life in years, then spreads it over your acreage. Excludes mounting/labor cost, mid-life repairs, retreading, financing cost, and any tire failures before expected life is reached. Default values are illustrative starting points, not benchmarks — replace them with your own fleet data.

Manufacturers and Competitive Landscape

The US agricultural tire market is served by a small group of multinational manufacturers, each with a different emphasis:

• Michelin — radial tractor tire technology, low-soil-compaction designs.
• Bridgestone — durable compounds and long tread life, strong US dealer network.
• Trelleborg — high-traction tires for precision agriculture and controlled-traffic systems.
• Continental — sensor-integrated tires for pressure and load monitoring.
• Mitas — competitive pricing across tiller, sprayer, and specialty segments.
• BKT, Titan/Goodyear Farm Tires — significant presence in the North American replacement market.

None of the sources reviewed for this article break out market share percentages by individual manufacturer for the US specifically — that level of competitive detail typically sits behind the same paywalled reports that withhold unit pricing. If you need manufacturer-level share, ResearchAndMarkets' and Mordor Intelligence's full reports (linked above) are the direct path.

For operations managing tire wear across a large machinery fleet, tracking usage and maintenance data alongside field conditions helps decide when replacement actually pays off. Farmonaut Fleet & Resource Management tools help coordinate machinery deployment and maintenance scheduling across an operation.

How to Verify These Figures Yourself Next Quarter

Every figure in this article carries a vintage — the specific report and year it came from — because market-size numbers age. Here's the durable method for checking whether they've moved:

1. For tractor tire market size: Go to ResearchAndMarkets' United States Tractor Tire Market page directly. Reports on this topic are typically refreshed annually; check the "publication date" field on the report listing before citing a figure from it.
2. For tractor/combine fleet size (a tire-demand proxy): USDA NASS QuickStats updates on a rolling basis; the Census of Agriculture's Table 45 machinery inventory refreshes every five years (next full census after 2022 is 2027).
3. For agricultural biologicals market size: Expert Market Research's United States Agricultural Biologicals Market report and Mordor Intelligence's biopesticides coverage are both updated periodically as new data becomes available — check the report's stated base year before treating a figure as current.
4. For annual tractor/combine unit sales (not covered by government sources): the Association of Equipment Manufacturers publishes quarterly US farm equipment sales data; industry groups like the Farm Equipment Manufacturers Association track segment-level activity as well.

This is the spine of the article that won't go stale: the reports change their numbers every year, but the four sources above and the method of checking them directly stays correct regardless of what the next report says.

Where Satellite Data Fits: Tire Wear, Soil Compaction & Fleet Decisions

Market-size reports tell you what the industry is worth. They don't tell you when your specific fleet's tires need replacing or where soil compaction from traffic patterns is cutting into yield. That's a field-level question, and it's where satellite monitoring complements — not replaces — the market data above.

• Satellite-based field monitoring — multispectral imagery helps identify compaction patterns tied to traffic lanes, which informs both tire pressure decisions and controlled-traffic planning. Explore this through Farmonaut Product Traceability Solutions, which pairs field data with supply chain transparency.
• Fleet and resource management — coordinating machinery deployment, maintenance intervals, and tire replacement scheduling across an operation via Farmonaut Fleet & Resource Management.
• Large-scale farm administration — for operations managing multiple fields or contractors, Farmonaut's Agro Admin App centralizes field logistics and equipment records.
• Carbon and sustainability tracking — tire choice and traffic patterns affect fuel use and soil carbon; Farmonaut Carbon Footprinting connects field practices to measurable sustainability metrics.
• Financing support — for operations using satellite-verified field data to support equipment financing decisions, see Farmonaut's Crop Loan and Insurance verification tools.
