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.
Thanks, Dale

Hi This is Dale again.
I looked at that web page and made a couple of comparisons. This information
is very interesting, however, I don't know yet whether the Safari vans can
accomidate the P235. I think that if I wanted to go one size up (from P205 to
P215), that a half an inch shouldn't cause any problem, but perhaps someone
else's reference material will have specific info on these vans. Thanks again
for posting this stuff.

I used to have an a 93 AWD Safari van and ran P225/70R15 Michelin X-One
tires in the summer. They were great tires, much better than the stock
Uniroyals one of which blew up on me. Those Michelins were on the van
until just before I sold it.

I hear you on the tire size. Best thing to do is go to the site
www.astrosafari.com and do a search cuz I know they have asked the question.
Otherwise, they can answer it for you. I have 225/70R15 which is same size
as your stock size. Another option is to search www.overlandvans.com and
decide if you want to do a little bit of lift to accomodate bigger tires.
Not sure if they mention maximum tires sizes on that size.
Regardless, a change in tire size will affect your speedo. One size won't
change it much but a few sizes bigger you may want to change your final
drive and/or speedo gear.

I have a 97 Astro that original came with 215-75R15.

I have experience using a set of 225-75R15 tires on it with some problems:

1. With full passenger seating (8 people in car) and some luggage in the
truck, the rear tires rub the wheel wells when it rides over relatively
minor road bumps.

2. front tires rub on maximum turns if there is any looseness or folding
of the wheel well plastic covers.

For these reasons, I would be going back to original size tires when I
have to change tires again.

Thanks to everyone who responded to my question. It would seem like going from
205-75R15 to 215-75R15 shouln't be a problem, as the diameter would only be
about a half inch difference. I will consider this the maximum size then.
Have a nice Holiday.
