Price is for TWO tires, sold as a pair. Order qty 1 = 2 tires. These are new 21X11.00-8 Carlisle AT101 Chevron bar lug tires. Carlisle is dual marking the sidewall with both the standard and metric size which is 280/60-8. They are 4 ply tubeless tires with a max load of 1430 lbs per tire at 22 psi. These are designed specifically for zero turn mowers, they have lug with tapered rounded lug ends to minimize turf damage. They are used as drive tires on zero turn mowers and offer much better traction than the turf tread tires. Double check your size before ordering these are for a 8" diameter wheel, there is also an 10" version and they DO NOT interchange. I include new TR412 tubeless stems with each pair.
