Hi all, I am the proud new owner of a very nice 1997 C3500. It will be replacing my dad's 1989 C2500 as the tow vehicle for my stock car.

The new truck will need tires soon. Is it reccomended/advisable to go up one size from stock? Currently, the tires just look a bit small, and bigger tires in the back might give me some better mileage since I won't be towing anything super heavy.

Can anyone suggest some sizes? Thanks!

 

265 75 16 or 285 75 16. or the equivalent if the rim isn't a 16"

Hi all. Question regarding sizes for the rear tires. The car I bought is dropped to RS ride height, and is wearing GT3 wheels. I am wondering what is the appropriate tire size for these, and what else might need to be done e.g. rolling the fenders so there isnt rubbing. Anything else that I should be aware of?Thanks
