Negative effects of installing larger tires on OEM wheels?

[Kabanstva]

What are some of the negative effects of putting larger AT tires on the OEM wheels?

I am thinking of putting some (265-285)/75/16 size tires on the OEM 16's.

Would it lead to any accelerated wear and tear on the suspension components/wheel bearings/etc.?

I've gone up one tire size on just about every vehicle I've ever owned and haven't experienced any issues. Ran 285/75/16 on OEM rims on both 80 series I've owned and am running 275/75/18 on OEM 100 series rims now and never an issue that I'm aware of.

I'm not aware of any significant increased wear from oversized tires when you're within an inch or two of the OEM diameter.

MPG will go down. Acceleration will go down. Braking will suffer.

I could notice immediately when I got my 285/75/16s. It felt like the truck was heavier. That being said, however, the benefit so greatly outweighs the drawbacks it's an easy decision for me.

Anytime you add weight at the wheels, you slightly increase the wear of wheel bearings, ball joints, tie rod ends, steering racks. Braking distance and fuel consumption both go up.

The small increase in tire size you're looking at will be almost impossible to tell the difference in everything except braking distance and fuel consumption.

I would look more at tire weight than tire size when considering any mpg differences. Tire weights vary significantly among brands, models, and capacities. Buying a slightly larger, light tire along with the effectively taller gearing may cause fuel consumption to go down, not up. It's a complex interaction but I would not automatically assume fuel consumption will go up measurably with a size larger tire.

Another negative effect is in your wallet when you then want to buy the lift, and then bumpers and then sliders, and then.....
