1999 Blazer 4x4
 

on a 4x4 can you have a different tread design on the tires ? on the door jam it says 235-70-15 and it has 235-75-15 on it, will that hurt anything being it's a 4 wheel drive ! i was told as long as all 4 were the same size that the tread didn't matter ! thanks !

correct, any tread you want as long as they are all the same
