I'm considering a slightly larger size tire than stock when mine finally wear out, and I have a few questions: 1. What size tire would you guys recommend for a rig with stock suspension (no OME) looking to move up a size? 2. I've found the Revos in the LT285/75R16 size on the web- if my calculations are correct, this is almost a 33" tire! Will this fit with no rub w/ my stock suspension? 3. Will there be speedometer issues when upgrading to a LT285/75R16? 4. The width of the LT285/75R16 is greater than the stock tire. Can this cause problems, and will it fit on stock rims? 5. Will a tire of the LT285/75R16 size cause noticeable power loss? 6. Will gas mileage go down with a larger tire (assuming the same rolling friction)? As you can tell, I'm a newbie when it comes to tires...any help on this would be greatly appreciated!
