1. I am considering replacing the stock tire (265/75/16) with new tires that are size 285/75/16. Will the 285/75/16 (approx 33" dimeter) fit the wheel well area?

My reason for the larger size is to increase the load range from 3415 lbs /tirr to 3750 lbs/tire, to better support a new truck camper that weighs about 500 lbs more than my earlier truck camper.

2 what are negative consequences of the new tire size?

2002 F350, SCab, long box, V10, 4x2

 

No real negatives as far as the tire besides mpg. you might have an issue as you're 2wd your front end well be lower then a 4x4. Have you checked how much you weigh? 500lbs shouldn't put you over the tire weight.

 

My dad and I have been running 285/75R16s on our SDs for over a decade. If you want to up size the tire on a 99'-04' SD the 285/75R16 is optimal IMO. The pros far outweigh the cons, however there are some cons.

- Stock rim width is 7" wide which is below the minimum recommended rim width by the manufacturers for the 285/75R16. This means you have the air the tire down a little more than a 265/75 in order to get even wear across the tread width on the back tires

- Another con is the approximately 1" diameter increase of the 285/75 vs the 265/75 or 235/85 will slightly affect the final drive ratio. This can be corrected with a gear change but most do not bother.

- On some trucks depending on how aggressive the tire is a 285 can scrape some molded mud guards.(4X4 trucks, may differ for 2wd)

 

What rim size is best for tires thst are 285/75/16?

 

My 16x9s fit the 285s very well.

 

Look at the recommended rim width recommendation by th etire manufacturer. Minimum most recommend is a 7.5" wide wheel for a 285/75R16. The stock wheel is 7". I would say a good rim width for the 285 would be 8" or so. However as I mentioned the stock wheels work more than fine. What I have against a lot of the larger aftermarket wheels is that they are cast wheels (instead of forged for OE) and are lug centric (vs hub centric for the OE).

 

i run 285's on 16x10 wheels on my truck. it's nice because it has the tough 35'ish look without the width penalty. a 10" wheel is wider than reccomended for a 285, but i've had no problems and they're wearing flat with no special psi games required.
