I am thinking about buying a new set of tires and bumping the size up to 285-75-16 on my 03 1500HD. will those tires look ok and fit right on the stock wheels?

 

That's what I have on my 1500. I have the Z-71, and they look really good. That as big as I could go without doing a lift.

 

BFG, did you notice any loss in power due to the greater turning mass? I've always wondered. My '08 has 265-17's on it now & they look small.

 

There is a little power loss, not too noticable during normalthough. On dry pavement I can't do a power stand anymore. That's due to the widerwidth and larger diameter. My gas mileage went down, but it's hard to say how much. I didn't correct the computer for the larger diameter tires, so it changed my speedo and odometer. However, with stock tires my speedo always read a little higher than the speed on my GPS. Now my speedo is dead on with my GPS. I have never paid attention to see if the miles match or not.

You have a 265 tire on you truck now? What's the aspect ratio? Is it a 265/65R17? If so, thats about 10.4in wide by 30.5in tall. If you stick with the 17in rim a 285/70 will look good.

 

I have the stock 245/75/16 on my truck right now. I just wasnt sure if the 285/75/16 would fit because of the width of the wheel.
