Farm tyres that care for your crops
Our farm tyres help protect crops while your machinery works across the field. By managing ground contact and supporting stable operation, they reduce unnecessary soil disturbance during everyday farming tasks. This allows your agricultural tyres to perform efficiently while helping maintain soil conditions throughout the season.
Agricultural tyre types: Choosing the tyres for your farm applications
Choosing the right tyre tread depends on your soil type, crop, and seasonal conditions. Each tread pattern is designed for specific ground conditions and applications across Australian farming operations. Below is a comprehensive guide to help guide your decision:
R1: Standard Agricultural Tyres
R1 tyres are the workhorse of Australian broadacre farming. Deep angled lugs provide maximum traction in dryland farming, general cultivation, seeding, and mixed cropping work. The wide spacing between tread bars self-cleans effectively, shedding mud and debris as the tyre rotates. Lug angles between 23 and 45 degrees pull the tractor forward efficiently across variable terrain.
These flotation tyres are common across WA wheat farms, SA barley operations, VIC mixed cropping, and NSW canola country. Standard choice for utility tractors between 80-200 HP doing general farm work.
R1W: Wet Traction Tyres
R1W tyres feature tread bars at least 20% deeper than standard R1, designed specifically for sticky, waterlogged, or saturated soils. The extra depth grips harder in wet conditions common to coastal regions, winter cropping zones, and high-rainfall areas. Southern Victoria, southern NSW, and wetter Western Australian regions see the most benefit during winter seeding and spring harvest when ground moisture is high.
Trade-off: deeper tread wears faster on sealed roads and hard surfaces. Best suited for operations where wet-season traction outweighs tread longevity concerns.
R2: Rice and Cane Tyres
R2 tyres deliver twice the tread depth of standard R1, built for extreme wet conditions like rice paddies, sugarcane fields, and consistently waterlogged ground. The aggressive bar pattern prevents bogging in standing water and deep mud. Too extreme for general cropping. R2 tyres are only practical for specialised operations working saturated ground year-round.
Used primarily in Queensland sugarcane operations and northern NSW rice farming. Rare outside these crops.
R3: Turf Tyres
R3 tyres feature shallow tread with closely-spaced lugs across a wide profile, designed to minimise turf damage on grass and maintained surfaces. The wider footprint spreads tractor weight, reducing ground pressure and preventing lawn damage. Ideal for golf courses, council mowing operations, sports fields, vineyard maintenance, and lifestyle properties where grass preservation matters.
Poor self-cleaning means R3 tyres clog quickly in mud or snow. Not suitable for wet paddock work or winter conditions.
R4: Industrial Tyres
R4 tyres sit between agricultural and industrial applications with tread depth roughly 70% of R1 and heavier sidewall construction. Block tread pattern delivers decent traction on construction sites while wearing well on gravel and sealed roads. Common on backhoes, telehandlers, small loaders, and tractors splitting time between field work and road transport.
Suits rural contractors, council equipment, and operations working mixed surfaces. Better road manners than R1 without sacrificing all off-road capability.

Ag tyres Frequently Asked Questions
See how our ag tyres can help your farm and harvesting applications by browsing our frequently asked questions below.
What's the Difference Between R1 and R1W Tractor Tyres?
R1 tyres are standard agricultural tyres with deep lugs for general field work. R1W (Wet) tyres have lugs at least 20% deeper, designed for wet, sticky, or muddy soils. The deeper tread grips better in saturated ground but wears faster on hard surfaces. R1W suits operations where wet-season traction outweighs tread longevity.
What Size Tractor Tyres Do I Need?
Match the tyre size to your rim diameter first, then confirm the width suits your application. Common rear sizes include 16.9-30 for 80–100 HP tractors, 18.4-38 for 120–150 HP models, and 480/80R46 or 520/85R42 for high-horsepower machines. Your operator manual lists approved sizes. Most tractors accept one or two alternate widths. IF and VF tyres typically need a rim 1–2 inches wider than standard.
How Long Do Agricultural Tractor Tyres Last?
Radial tyres last 3,000 to 5,000 operating hours, translating to 6 to 10 years for tractors running 500–1,000 hours annually. Bias-ply tyres wear faster at 2,000 to 3,000 hours. Lifespan depends on surface type, load, and pressure management. Tyres working on gravel, rocky paddocks, or sealed roads sit at the lower end. Field-only tractors with proper pressure reach the upper limit.
What's the Best Tractor Tyre for Wet Conditions in Australia?
R1W or R2 tread patterns deliver the strongest wet-ground performance. R1W suits general farming with seasonal wet periods. R2 tyres, with double the tread depth of R1, handle consistently waterlogged conditions like rice paddies, sugarcane fields, or heavy clay. IF and VF tyres also help by spreading load across a wider footprint, reducing ground pressure and bogging risk.
Should I Run Radial or Bias-Ply Tyres on My Tractor?
Radial tyres are the better long-term choice for most operations. They last three to five times longer than bias-ply, run cooler, deliver better fuel efficiency, and reduce soil compaction. Bias-ply tyres cost less upfront and suit older tractors, light-duty work, or seasonal machines with low annual hours. For tractors above 80 HP or logging 500+ hours per year, radials deliver lower total cost despite the higher price.
What Pressure Should I Run My Tractor Tyres At?
Correct pressure depends on load, speed, and surface. Most field work needs 12–16 PSI for rear tyres, 18–24 PSI for road transport. Too high increases soil compaction and centre tread wear. Too low risks sidewall damage and higher rolling resistance. Check your tyre manufacturer’s load-inflation tables and adjust based on whether you’re working in-field or on sealed roads.
Do You Supply Tractor Tyres for Sale Across Australia?
Yes. We supply agricultural tractor tyres Australia-wide with delivery to Western Australia, South Australia, Victoria, New South Wales, and Queensland. We operate depots in Perth, Geraldton, Kalgoorlie, Karratha, Port Hedland, Mildura, Eastern Creek, Muswellbrook, Brisbane, Mackay, Emerald, Gladstone, and Mount Isa. We stock Michelin, Bridgestone, and Goodyear, and offer on-site fitting for regional and remote operations.
Can OTR Fit Tractor Tyres On-Site?
Yes. We can provide on-site tyre fitting and servicing across all our operating regions. Mobile service includes tyre replacement, repairs, pressure checks, and emergency callouts. On-site fitting reduces machine downtime and eliminates workshop transport, particularly valuable during seeding, spraying, and harvest.
What Are Flotation Tyres and When Should I Use Them?
Flotation tyres are wider, lower-profile tyres designed to spread load over a larger contact area, reducing ground pressure and preventing bogging in soft or wet ground. They’re used on high-clearance sprayers, irrigation tractors, and harvesters working in-season when soil moisture is high. Flotation tyres reduce compaction and rutting compared to standard-width tyres carrying the same load.
How Do I Reduce Soil Compaction with Tyre Choice?
Choose tyres that allow lower operating pressures while supporting your load. IF (Improved Flexion) and VF (Very High Flexion) tyres carry 20% and 40% more load at the same pressure as standard tyres, or the same load at lower pressure. Lower pressure means larger contact patch and reduced ground pressure. Radial tyres outperform bias-ply for compaction control. Dual wheels split load across two tyres instead of one.
