i run 285/75R16 with a leveling kit but no offset

Thats what I want to know having the offset will that cause a concern? Some people tell me it will and some say just gonna stick out a little more

Those 265s look a little tight. You can run 285s but I would only go with the 75 sidewall the 85 is going to be taller and will probably rub.You will also have to turn the tbars up a little to keep from rubbing too bad. Mine will rub a little on extreme left turns with my tbars up 4 turns. I did not want to go higher and sacrifice more ride quality. You will also have to trim the air dam a little.

Sorry to go off topic for a sec but I noticed you run the dialblo have you had anyproblems with it on the truck I have done so much reading on chips and pretty sure I wat that one, Also regarding the tbars how do you tell if they have been turned?

I have never had any issues with my Diablo. I have had fuel delivery issues on the 120 tune but I need a lift pump to give her more fuel. I cannot tell you, if you can tell if the t bars have been turned up already but judging from your trucks stance I would say no.I would go with EFI Live if you have the money to purchase it. It will be the last programmer you will ever buy. They are pricey but you can tune mutiple trucks with it( For $100 a Vin)

im running 285s with t-bars cranked and no trimming

I know you can run 285's with stock 17" rims but I have a offset so I want to make sure they fit

So I can't fit the tires under without a level kit so I guess I have no choice, I really want the bigger size if I do the kit can I run some 315's just not sure the size... Worked out well when they went to try the tire on the truck learned that both front wheel hubs worn out I mean right out, so gettin them done under warrenty...
