35's or 37's Help Me Out!
 

I ordered my 2.5" leveing kit the other day. Now im tring to decide what tires i want.Imgonna run 20"x9"wheels. I have seen jesses psd on 37's and it looks sweet. anybody got some pics of their ride with 35's and a leveling kit?

Also I am running a Spartan with the 250 tune with a heavy foot. Would i run into problems if I ran 37's? To help out on this i know some tires run a bit small compared to the same size as other brands. What tire would run smallest to help decrease the risk. (if there is any)

Mine has 325-60-20's (35's)and they rub a hair with the stearing maxed out.

power wise, you may feel a small difference, but the truck will have no problem moving those 37's with stock gearing. I have a few buddies who have tuned 6.0's, crew cab short beds on 37's with stock 3.73's, and no issues.

The only issue I can see, is if you're towing a lot... I'd stick with 35's then.

My truck has 3.55 gearing and I could tell a small difference when towing and I saw a prety big diference in fuel economy. Prety sure if I had 3.73 gearing I wouldn't be able to tell anything.
