i have a 2007 2500 HD and was wondering if i could put 305\50R\20's on with just a leveling kit or would i have to have a bigger lift orwill they fit without any lift??
Thanks

 

I believe the biggest you could go with stock suspension is 275/60-20. You might want to check out website TireRack.com.

 

i think it would work, i know 285/75/16 works, and the 305/50/20 is almost an inch shorter and an inch wider... i think it'd work, but im not sure

 

Tire rack has good prices, but be careful as their tires sit for a long time and tend to get sidewall bulges easily. My friend used to get all his tires there, then started getting the sidewall bulges on 1-2 out of every set he bought, and he has 4 cars, so he bought alot of tires.
