27x8.50-15 Compact Tractor Tires

Buying 27×8.50-15 tires

27×8.50-15 is a front tire for compact and sub-compact four-wheel-drive tractors. It is made with R-1 lugs, R-4 industrial tread and R-3 turf tread to match the rears. This size format gives three numbers: an overall diameter of about 27 inches (686 mm), a width of about 8.5 inches (216 mm) and a 15-inch rim.

Turf or lug tread?

• R-3 turf: shallow, closely spaced tread that protects lawns. The usual choice for mowing and grounds care.
• Lug or all-purpose: more grip in dirt, gravel and snow, for towing carts or running a blade. Harder on turf.

Our tread types guide explains the difference.

Easy to confuse

• Matching the rears: on a four-wheel-drive compact, the front and rear tires are matched so both axles turn at the right speed. Keep the same tread type front and rear, and don’t change size on one axle alone.
• 27×8.50-15 vs 27×10.50-15: same diameter and rim, different width. Check your sidewall.

What to check

• Rim width: a wider tire needs a wider wheel. Read your sidewall and the rim before changing size.
• Ply rating: 4-ply and 6-ply are common. Go higher for heavy loader work.
• Tubeless: most are tubeless. A slow leak is often a bead or rim problem, not the tire.
• Used tires: small tires often dry-rot before they wear out, so check the date code and look for cracks.
• Pairs: replace tires in pairs so the machine sits level.

Other compact and garden sizes include 23×8.50-12 and 26×12.00-12. Send the quantity, tread and delivery location for a quote.

The nominal overall diameter is about 27 in (686 mm), which gives a rolling circumference near 85 in (2,155 mm). That figure is taken from the size itself. Real tires vary by make and load, so treat it as a guide and use the tire diameter calculator or the lead-lag calculator before you change size on a front-wheel-assist tractor.

Is 27×8.50-15 a radial or a bias tire?

It is a bias-ply size. The dash in the size marks bias construction, which costs less and has stiffer sidewalls. See the radial vs bias guide.
