I was looking at the specs on both of these tires and I see that they are not very different from eacother. the 32x11.50 is only .80" smaller than the 285 and the 285 is about .30" skinnier than the 32x11.50. So my main question here is that since the tires are sooo close then why is so much more necessary for the 285(higher lift,gears,gas mileage,etc..). Mainly it is highly recommended to regear with the 285 and not with the 32x11.50... does .80" really have that much effect. Also people with the 285's talk about a large gas mileage difference, and this is usually not a factor when people talk about getting the 32x11.50's. I was just wondering... :confused:

a 32" tire is usually not a true 32 inches. There is about an inch difference in height, thus the amount of lift difference (easier to rub on bumper/pinch weld), not to mention weight. This could attribute to the difference in gas mileage and the higher the response in gears. I guess the 1/3" skinnier tire doesn't mean much? Just some thoughts from my end, no hardcore facts/science here.

285s are typically taller. A 32x11.5-15 BFG A/T is 31.7", the same tire in 285/75-16 is 32.9"...a 1.2" difference. For a Goodyear MT/R, the difference is more like 1.6". Also, please know that the "need" to regear is highly subjective.

I'm getting ready to put a set of 285 MT/R's on mine, but don't plan to re-gear for a while. THese tires are as close to a true 33 as your get, they didn't feel to heavy but when I brought 4 of them home in my VW Jetta, she was struggling a little. I'll let everyone know how it turns out once I install my lift and get some rims.

I'm not too worried about it, I'll eventually re-gear. I was really crapmed with the tires in there, It was so tight that I couldn't shift into fifth. It was crazy should have taken a picture, but all you would see would be tires. :D

When running a 32x11.50 you are getting a 6 ply, but when running a 285/75 you are getting an 8 ply tire in most cases. This makes for a heavy tire, ruffer ride, and less mpg.
