285/75/17 (34)are a bigger tire then the 285/70/17 (33)
discount tire has a good tire comparison tool.
75 are 1.12" in diameter bigger .57" sidewall height bigger.. the width is the same.
so it's a 34 vs a 33
with that said.. here is another pic of 285/75/17 or 34's
I wanted a little more than a 285/70/17 but the price of the 285/75s are about the same.as the 35/12.50. Be nice to find a decent priced 285/75 but they aren't common. I didn't quite want to go the 35 route due to all the necessary upgrades including gears.
Well, since I upgraded my tires to GY Duratracs 285/70r17's, a TF 1.5" leveling kit, and Spidertrax wheel spacers over the Christmas holiday, my JKU handles very well on smooth roads. But on bumpy roads, the wheels resonate and jar the impact vibrations up the steering column. I now get plenty of feedback from crappy road conditions.
I am choosing the FOX ATS after careful research based on other owners' experiences with all of the different options they had either tried and/or liked or didn't.
I did my best to try and stick to owners' set ups similar to mine or who were experiencing the similar issue that I was contending with.
The Bilsteins for many folks forced the steering to pull left in many instances. Most of the 'shock type' stabilizers had a tendency to do this. However, the FOX ATS has a different approach all together in its design. It doesn't have forces naturally pulling or pushing it. It is a pass-through design where turning either left or right, it is simply balanced - not pulling or pushing. Nevertheless, there is a setting to dial up its pressure to control how it handles and reacts to certain driving conditions by the forces impacting the steering from the wheels. The FOX's ATS steering stabilizer's dial adjustment's settings also have a lot to do with tire diameter and the stresses larger tires and wheels put on the front suspension. Whether it's a 33 or so inch tire and wheel setup like mine, or a rock crawler with 37's, the FOX ATS SS covers a wide range of suspension setups, even on a little JKU like mine.
The FOX is a little pricey at $350+, but from so many of the reviews and forums that I have referenced other JEEPERs' experiences, the FOX seems like a favorable mod for a lot of these folks, in its capability to drastically reduce 'sawing', steering wobble, and resonance and impact vibrations from harsh road conditions.
I need something like that.
