Tire size question

[psd76]

I have an 03 PSD. Totally stock except for gauges. Exhaust and an itake coming soon but first I need new tires. I am leaning towards BFG all terrains. My question is what is the tallest tire that I can put on stock rims without any rubbing or a lift kit 285, 295 or 305. Right now I am running the stock Firestone Steeltexs 265/75R/16E. Is the 295 or 305 equivalent to a 33x12.50. How much fuel mileage would be lost. I mostly do around town driving and during the winter I tow 2 sleds upstate and a 21' boat in the summer. Hopefully this isnt a stupid question. Thanks.

I've heard several people say they can get the 305s under stock height trucks, I'm sure some of them will be along to confirm this -- or not hahaha,

ive heard a bunch of ppl say alot of differnt sizes you can stuff, but i think to be safe go with the 285's i dont believe youll have any rubbing issues, and the minuete tire increase wont effect much

285x75R16 is equilivent to 33x11.50R16, 305x75R16 is equilivent to 33x12.50R16 the 295x75R16 is a half size it is in between the 33x11.50R16 and 33x12.50R16.

You are correct stump 285x75R16 will not rub at all. I have been running them on my truck since the second day I owned my truck. I didn't even wait to wear out the firestones that were on my truck.

I just changed to 285's from 265's and they fit just fine and yes you will lose some mileage as you go to the bigger tire. This will also change your odometer and mph gauge unless you can have it setup for your tire size.

this is an awesome clculator that will give you the diffrence from changing tire sizes

Is a 285/75 16 the same overall size as a 285/75 20? Or does the wheel make the overall OD larger?

i dont belive it does just makes the side wall smaller

I was wondering about that...my 20s side does seem a little smaller for a 265/75 stock tire...Thanx Stump!!!
