No sweat running 285 70 17's on your Off-Road, Greg, did it on mine. They work really well with our 4.10's and I'm out 5% on the odometer.



The added lift from the factory helps for clearance on the front, I just had to trim my front flaps a little.







Also, I highly recommend these Michelin LTX AT2's: they are the narrowest 285 you can get, they are very quiet on the highway and the mileage is unreal. I'm over 120,000 miles on these and am just about hitting the wear bars. I'll easily get another 10 or 20 out of them. You get what you pay for though, they don't give them away.
