Hi I just got a new set of 18x9 rims with +18 offset. I have a 11 2500hd got my t bars turned up so it sits leveled My stock rims have 265 75 18. I like the size because with my snow plow on nothing rubs. But wouldn't mind going bigger and not to many options in that size in load range E. So thinking of 285 65 18 or 275 70 18. I guess I need some input from you guys to make a get the right width and height for my new rims. Thanks for any help you can offer.
