2009 2500hd LMM...like to replace tires with 265's or 285's. Can this be done safely with stock 16" wheels? Do I need to reprogram computer? If I buy tuner and do this myself, will it void warranty? I have the ready lift 2" lift installed allready and just need some decent tires wheels.
Yes, 285s' will be fine, Your mileage will be off by about 4 mph at 65 to 70.

and im gonna put new injectors in when i do that
welcome to the DF..
will it work yes,it would recommend doing a 8" wide wheel for the 285's but the OEM 6.5" wide wheels will work! you could do the Hypertech Tire Paq if you just want to adjust speedo and that shouldnt void your warranty but if you realy want to make sure you dont viod the warranty just have the dealership recalibrate your ECM for the larger tires!

My friend just added 285-75-16's to his 2009 and he had to crank the T bar's to get them to fit and they are REALLY close to touching but the T bars are not maxed out..I think they have a turn or so left.
