tire size on new s/10 blazer
I have a question. On my 2000 S/10 Blazer with premium ride suspension (ZW7) I have 235/75R 15 tires. I would like to upgrade to Cooper discovery STT in 30 x 9.50-15 this new tire is 30 inches compared to 28.9 with the factory uniroyals. would these new coopers fit without modifying anything , and most importantly would it affect my warranty.
