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 comparing the tire specs, you will see that they are almost identical
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.
