What 23x8.50-12 means

Every number on the sidewall is telling you something. Here's this one, decoded:

  • 23Overall diameterThe tire stands about 23 inches tall when inflated and unloaded.
  • 8.50Section widthAbout 8.5 inches across the widest part of the tire.
  • –ConstructionBias-ply. The plies run diagonally, which gives a stiff, tough sidewall.
  • 12Wheel diameterFits a 12-inch wheel. This is the number that has to match your rim exactly.

Size is only half the answer

Two 23x8.50-12 tires can be built for very different work. Ply rating or load index sets how much each tire carries, and the tread code sets the job: R-1 and R-1W for drive traction, F-2 for front steering, I-1 for implements and wagons. Tell us the tractor or implement and how it's used, and we'll match the tire to it.

We also carry 23x8.50-12 as construction & OTR tires and lawn & garden tires. Same numbers, different build. Tell us what it's going on and we'll steer you to the right one.

Other sizes on a 12" wheel

These share your rim diameter. Whether one of them will actually work depends on rim width, load range and fender clearance. Ask us before you switch.

23x8.50-12 questions, answered

23: The tire stands about 23 inches tall when inflated and unloaded. 8.50: About 8.5 inches across the widest part of the tire. –: Bias-ply. The plies run diagonally, which gives a stiff, tough sidewall. 12: Fits a 12-inch wheel. This is the number that has to match your rim exactly. Altogether that works out to roughly 23 inches of overall diameter.

Many farm sizes are made both ways. Radials put more tread on the ground, ride smoother and are easier on the soil; bias tires cost less and shrug off stubble and sidewall knocks. Equivalent bias and radial sizes are close in height but not identical, so tell us if you're mixing them on one axle or on a front-wheel-assist tractor and we'll check it works.

It's made as both. 23x8.50-12 is a size, not a build. The same numbers are produced in constructions aimed at different jobs, with different load ranges and tread designs. We carry it on the agricultural & farm side and the construction & OTR and lawn mower & garden side, so tell us what it's going on and we'll point you at the right one. Call (320) 363-7246 if you're not sure which you need.

We carry 4.00-12 in the same 12-inch wheel diameter. Sharing a rim diameter doesn't guarantee a swap will work, though. Rim width, load range and clearance all have to line up. Call (320) 363-7246 and we'll tell you straight whether a change makes sense.

Stock moves, so the honest answer is to check. Send us the size through the availability request on this page or call (320) 363-7246. We'll tell you what we have on the shelf, what load ranges are available and how fast we can get anything we'd need to order.
