So we bought a really nice 1 owner 166k mile 2006 Chevy dually LBZ last year, and wow what a truck!
*waits for the applause*
It came with some really nice aftermarket goodies, also, and never chipped.

It has the factory 16s with 215/80/16, and I'm looking at different options for wheel/tire sizes, WITHOUT having to lift or cut anything, OR use spacers.
Was thinking 235s with the later model's 17" wheels.

thoughts, opinions and experiences all welcome!
TIA guys.

I don’t know if it helps, but I have a 1999 Silverado 4wd Z-71 with 18” rims. I put on 275/65/18 tires and they clear everything fine. I don’t remember the stock size 16 inch tire size, but I just looked those up to get the diameter and chose an 18” tire with a similar diameter. The ones I chose were only a few tenths of an inch bigger. TireRack even called me to warn that they may be too big and rub. But I assured the guy they would be fine, that I checked the specs. He said mount them and turn the wheels side to side before driving anywhere to make sure.

Friends don’t let friends drive Fords.

Oversize tires are usually much heavier than the tires that come stock, the extra weight and height of the tire will affect performance. The taller the tire, the higher the gear ratio will become. Larger tires will also have a larger rotating mass due to the increase in weight. Both of these issues will result in a loss of low end torque. Your engine will have to strain harder to get the wheels rolling at the start. The smaller the engine, the more it will affect performance and put a strain on all components not to mention up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.

you can get the same size tires in 16s, and not have to change wheels/rims.

What are you trying to do...?
