I'm trying to find information on the allowable tire sizes for my '93 GMC
Safari Van. I just came from GMC's web page, but they don't seem to list any
such information on there. My owners manual and shop manual offer no such
information. My van originally came with P205-75R15, and I'd like to know
whether I can install P235-75R15 on it. I have an S10 which uses the P235, and
so I tried to compare the two tires by holding a tape measure up to them. When
I measure from the ground to the top of the P205, I get about 26 inches (or
going sideways accross the tire, I get about 27 inches diameter).
Now when I measure from the ground to the top of the P235, I get about 27
inches (or going sideways accross the tire, I get about 29 inches diameter). I
hope that someone out there will have some reference material that they can
check for me. I will attempt to find this online, but I wanted to drop a
message here first.
I know that the safest thing is to stay with the original size, but if I can
use the P235, then this might be an advantage, I believe.
