Your wheel size has no bearing on your speedo. It's the total diameter of the tire. So, if your new wheel/tire setup is roughly the same diameter as your old wheel/tire diameter, you are good to go...

 

Ok thanks a lot

 

i now run the 17's with 315/70/17 it's 34.9 od i change rim size because of the cost to go bigger on 20's and didnt like the look of the stock wheels i like to be different. my wheels are made kuza and are called panthers with bfg a/t. i paid 1300 otd for these and to do with the stock wheels it would have been a least 1400.

 

Did you install a leveling kit to clear the bigger tires??

 

Would these fit a 07 ram 1500?

 

Im not sure check the lugs on it... the new rams are 5 on 5.5
