Going to 37's and cant decide which way to go. I currently have 35's and 18" wheels. It looks good but its time for a change. Im sure the 37's with a smaller 17" wheel will ride better and tires/wheels will cost less for sure compared to an 18 or even 20.

 

Honestly you wont feel much difference between a 17" and 18" ride wise. Unless you are just tires of your wheels, I would just keep them and get the 37's. I personally wouldn't even consider the 20's though...

 

I dont offroad it at all that much, if i do, its very light duty. Really like the looks of 37's and 20's, only a few wheels in 20's look good IMO.
