Verify rim diameter and load requirements

Confirm your vehicle uses an 8-inch rim diameter before ordering. Check that the load index 45 and speed rating F meet your machine's specifications. Note that the purchase includes the tire only; the rim is not included.

Suits recreational off-road riders

This tire suits riders needing durable all-terrain traction for ATVs and UTVs. Buyers requiring higher load capacity or speed ratings should look at other options. Those needing radial construction or run-flat capability will not find those features here.

Questions about this item

Does the 18X9.50-8 Carlisle Knobby come with the 8-inch rim, or is the tire sold alone?

The listing states the rim is not included; the purchase covers the tire only.

The sidewall shows 45F and 2 Ply — which load or speed version should I pick for a typical ATV?

Load index 45 and speed rating F are fixed for this size; the 2-ply construction matches the published load range A.

What does the 50 mph speed rating mean when the tire is fitted to an ATV on mixed terrain?

The F rating certifies the tire up to 50 mph; the knobby tread and bias-ply build maintain that capability on all-terrain surfaces.
