Called my local tire shop to get a set of Bridgestone Revos for my "05" Canyon crew cab. Stock size is of course 265/75 15. I've been told that 70's in this size are fine to use. The dealer, who already quoted me a price to put them on the Canyon says he can't because it's different that OEM and the load for the tire is less,(which I believe). So I called another dealer who will put them on but can't guarantee they'll work. My question is for all you guys running Revo's, what size are you using and are you using stock wheels or aftermarket? Also, anyone using 265/70 15's on a crew cab Canyon having any problem with them,( such as rubbing,etc)? Sorry for the dumb questions ,boy I wish bridgestone made the stock size. Any other options?

31/9.5? I'm running 30/9.5/R15 only because they came off my Blazer and they were practically brand new. I know they are a little small for the truck, so I think I have read the 31's will work. Good luck, the Revo's are a great tire!! :twisted:

So very little difference, Canyon. So would the 70 tire work and be safe in your opinion?

thanks for the data

Your welcome.. I used the tire calculator on 1010 tires for that data..

I see no problem with that setup IMO. The load carrying may be affected as mentioned because of the decreased sidewall..? I am not a tire expert in any means though.

The speedometer will be reading faster because of the decrease in overall tire diameter. You should look into a PCM tune afterwards to adjust for that change, so the gauge will read accurate.

Some places will just not take any chances in replacing sizes other than OEM.... That may be what you are up against.

If you do not get the computer re calibrated for the smaller tires, you will put on a few more miles than you would if you use the OEM Tires. Granted, it is only 3.5 miles for every 100 miles, but over 50,000 miles that will be about 1,700 miles. Miles that you really did not travel, but the engine, transmission, and all other power train pieces did.
