Re: tire size step up
Okay, my truck came factory with 265/75R16's. Now it has 285/7R16's. My speedo is off a little, and my odo is too. Shifts a little different, I think a little higher. One of these days I will get off my lazy butt and get it fixed. That's assuming I have the cash around. Really, you could drive it around and not notice to much of a difference.
Oh yeah, and about the tires. You can fit up to a 285/75R16 (33X11.25R16) on the stock rims without any rubbing. They also fit if you put them on aftermarket 16x7's with the same backspacing as the factory rims. RyanB tells me that the 305/75R16's (33x12R16) fit on the factory rims to without any rubbing, and he knows what he is talking about, so I'd say they will work too. They will rub if you put them on 16x8's or 16x7's with different backspacing from the stock rims. My 16x8's had both, and the 285/75R16's rubbed bad before I put the lift on. Hope this helps.
