21x8.00-10 Firestone 4 Ply Turf & Field
Firestone has discontinued this tire.
You will need to use 205/65-10 or 20.5x8.0-10 Kenda.
When you compare the tire specs, you will see that they are all most identical.
For more tire specs, see "Details" above.
My local tire dealer said these tires were no longer made and that I would have to either modify or replace my tractor when the old tires would no longer perform. This was obviously not the case. These brand new tires matched what was already on the tractor and work perfectly. I had them mounted at a Tires Plus for under $20 with new valve stems and all.
