I ordered some wheeler (pro-comp) 16x8 alloys. They have 4" Back spacing. here is the link

the tires I had on the stock 16x7 wheels were 265/75/16 and they fit fine. I guess they are slightly taller than stock.

What is the best size I can run? I don't want any rubbing and I do not offroad, just a little mud here and there.

 

I would stick with the 265/75r16.

 

Thanks, thats what I ended up doing. Seemed like anything else had the chance of rubbing
