Will 215/70/15 tires be safe to use on my 2 wheel drive 2003 blazer? I know the door tag does NOT call for this size but I do NOT like 235/75/15

 

I believe that some of the S-series trucks came with 215/70/15's. Your speedometer will be off, and your odometer will roll faster than it should (accumulate more miles than actual travelled).
