I am looking to put some bigger rubber on my 03 lb7 (285 75 r16) Not changing the rims. Will there be any affect on the transmission, transfercase, or rear end by putting on oversized tires?

No, you should be good to roll you may have to crank the t-bars a little bit.

Just going up to 285's from the stock 245's shoudn't be any prolblems, your speedo might be a couple of mph's different but that's about It!!:D

Absolutely,.......putting larger tires on will definitely put more wear on parts,...but you may not notice it for 200,000 miles,...or next week you could blow a wheel bearing.....ya never know.

a 285 is considered an oversided tire?:rof slap some 35's on it and run the hell out of it. about 80k miles later youll have pratically a new truck again. ask mine.

I have had larger tires since the truck was new. I changed the speedo with a hypertec speedo calibrator. I have had no problems in 111000 miles and about 40% are heavy towing. I dont abuse it though.
