Tires

[dmini]

I know that this has been discussed many times but here goes. I have a 2015 Silverado 2500HD double cab, stock tires are 265/70R18, what is the biggest tire I can go without cranking torsion bars? I am thinking about going with BFG's. Thanks

Also, there is a search feature in the far upper right of the main page if you want to find more threads about this or any other topic. Good luck.

Yep, that link above has some good information. Here's the short version...275/70/18 and 285/65/18 will both fit on a stock truck without any mods. There are a few other sizes, like 295/65/18 and 285/70/18, that will be close...and might rub depending on your particular truck, and things like mud flaps. If you're willing to crank the bars, then you can go up to a 295/70/18 or 285/75/18. And, just FYI, all of this applies to running stock rims...

I did the toyo mud 285/70/18 on stock wheels. I would bet the farm they will fit without cranking. If I would have found this forum a week sooner I would have done the same tires or maybe even the 295/70/18 toyo muds on stock wheels and drop shackles in the rear. I never would have touched the front end. I posted pics on another thread and you can see the wheel space clearly.
