Dealer says No to speedo recalibration
#16
When I had my 315's, they were 601 revs per mile. SOME of the 315s depending on brand, etc are more accurate at 606. One brand 315 may not be the exactly the same size as the next brand. So much for standards....
Anyhow, you can fit a slightly larger 35x12.50 17 on the trucks without rubbing using the stock wheels. I believe anything larger rubs on the fender and control arms without a lift. If you have pretty much any lift, you can probably run a 37, but you're probably still going to rub the control arms a little.

Hey I've got a question. I am running 35" BFG m/t tires and need to recalibrate. Could someone with DRB experience in Canada tell me if it is revs per mile or revs per kilometer in our trucks, and if it is revs per kilo, does anybody have that conversion. Any help would be apreciated, something I should have done a long time ago judging by the driveability change.

I finally got my truck back after 3 weeks with a dead ecm. I had them calibrate the speedo when it was new and told them I wanted them to do it for the new ECM as I already paid for it. They said only 285/70/17? That would explain why it was wrong before too. That would suck if that's it because I finally got aftermarket wheels and Toyo MT's in a 35/12.5/18. I liked my STT's but have always wanted the 35 MT's in E rating. Anybody know what's up with the 06's and speedo? Thanks.
