new tire /factory wheel?

Hi, looked at new tires today. I have the factory
17x7.5 wheel. Stk 255/75/17

Local tire store wanted to sell me. 285/70/17
He said it would fit. They are. 32.7 tall about 11wide
And stock is. 32.1 x 10 wide..

Is anyone running that size?
The tire. Bfg all terrain KO's

I'm running 285/70/17. I am going to go with flat flares soon. No rub on turns, but not much flex room.

yours looks good 2 / I wonder if it will fit as good since factory wheels are only 7.5 inch wide, where your wheels are 17x8 - correct??

Someone did a thread a few months back about 285/70s on a stock wheel with no lift and he said it rubbed real bad. Go with a 265/70/17, its a more common size than a 255 and is a bit bigger with no rub.

The 285 will fit. You will probably need spacers to avoid rubbing. Yes, I went with 17x8.

The 265/70/17 is about .45" smaller then the 255/75/17 on average (different tires vary a little within the same size) but the 265/70 is wider then the 255/75 by about the same amount. Speedometer reading with the 265 will be 1.41% too fast. When your speedometer is reading 60mph you are actually traveling 59.14mph.

the 285/70/17 is about .65 taller and about .50 wider then the stock 255/75. Speedometer reading with the 285/70 is 2.03% too slow. When your speedometer is reading 60mph you are actually traveling 61.19mph.

I seen a Wrangler mtr/ kevlar 275/70/17 - about the same size.. except its a mud- rather have a BFG..

It just cannot be straight forward... / I really do not have any faith in the stock goodyear SRA tires- dealer told me they are all -season / but they are truly just a highway tire.. I always like a real- all terrain ( like the ko, BFG ) still look aggressive, not as much as a mud/ most of my driving is on road / snow / some dirt and sand

It is too bad they don't make a 275/70/17 more available. It would be a great compromise and would probably fit

I just swapped the stock 255/75/17 SRA's with the 265/70/17 BFG KO's last week. Fit and look great and no rubbing.

No new pics yet bud! I'm sure the 285 would rub a bit though without some adjustment. I would stick with the C load range for better ride quality.
