Tires & Wheels

Shop TrailMaster Mid XRS tires and wheels, including replacement tires, rims, front wheel bearings, hub caps, valve stems and wheel hardware.

Read the size printed on your existing tire before ordering, and match the front or rear wheel position. Mid XRS listings include 145/70-6 front tires and 16x6-8 rear tires. Confirm your kart's actual setup, especially if its wheels have been changed.

Compare rim dimensions, bearing numbers and hardware sizes. Check whether each listing includes one tire, a pair of tires, a rim only or a bearing kit. Not sure which model you own? Identify your TrailMaster before ordering.
