Issues with running 285/70R17 tires

Asked my local les schwabb dealer for pricing on 285/70R17's and he advised against it because he thought it would hurt the diff. make it turn too much or confuse the computer. Any thoughts guys?

As long as all four tires are the same size, the computer won't care what size tires you have. You may trip the ESP accelerating out of tight corners occasionally and you will have about 10% speedometer error. Not sure about what lift you have, but you will get significant rubbing with 2" and even minor rubbing with a 4" lift running 285's.

Thanks kmax! I didn't want to believe the guy but figured it was worth asking the experts. I'm not sure I will go with that tire because of the possible rubbing. Another tire shop said they would do a test fit for me to check for that. THANKS

You will have to bend the pinch weld back and reshape or cut the wheel well and you should only have minor rub after that during off road conditions.

The ESP goes off even with 245/70R17's at times.

Is this the reason that the dashlights go on sometimes, well now I know don't need to worry anymore.

Be careful to check the clearance of the upper ball joint stud--I have 265-65/17 and I have a very slight rub and am thinking about shortening the stud.

Unless you have a 4 inch lift I wouldnt attempt going with a 285/70. Even if you have a 2 inch lift I wouldnt recommend anything larger then a 265/70.
