23x8.50-12 Garden Tractor Tires

Buying 23×8.50-12 tires

23×8.50-12 is a common rear tire on lawn and garden tractors and some sub-compact tractors. This size format gives three numbers: an overall diameter of about 23 inches (584 mm), a width of about 8.5 inches (216 mm) and a 12-inch rim.

Turf or lug tread?

• R-3 turf: shallow, closely spaced tread that protects lawns and grounds. The usual choice for mowing.
• Bar lug (R-1 style): deep lugs for traction in dirt, mud and snow, and when pulling a cart, plow or snow blade. Hard on lawns.

Our tread types guide covers the differences.

What to check

• Size match: garden tractors often use 23×8.50-12, 23×10.50-12 or 24×12-12. Read your sidewall; a wider tire needs a wider rim.
• Ply rating: 4-ply is common. Go higher if you tow heavy carts or run a front blade.
• Tubeless: most are tubeless. A slow leak is often a bead or rim problem, not the tire.
• Pairs: replace both rears together so the mower cuts level.

Other compact and garden sizes include 26×12.00-12 and 20×8.00-10. Send the quantity, tread and delivery location for a quote.

How tall is the 23×8.50-12 tire?

The nominal overall diameter is about 23 in (584 mm), which gives a rolling circumference near 72 in (1,835 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 23×8.50-12 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.
