tires and rims..

[perhie15]

hey yall i just bought a hills green cummins and now i gotta make it look sharp, so just wondering what size of tire/rim dimensions i need to fit on the truck without rubbing, A maximum tire size i can go besides a 275, im thinking 295 might be most? just that some tires i want dont make them in 275/70s and hardly any 20" so ill probably get 18" cheaper anyways haha!!

thanks in advance

and yes i did see the tire wheel faq but seems to be outdated doesnt have my year of truck on there.. so i did do a quick search to see if anything was out there and couldnt find

and one more thing, ill be putting on a leveling kit to not to sure how high i should go? 2.5" maybe? or what are the guys usually doing 2"?
