Question New Steelies + Tires, Wondering About Scrub and Rub

I'm looking to get a set of Discoverer S/T MAXX 255/80/17 and Mopar 52124455AB 17x7.5 w/ 47.3 offset steel wheels.

I currently have a 2015 Rubicon which has stock KM 255/75/17 and 17x7.5 w/ 44.45 offset. I have stock everything else.

With the new set, I tried to do my homework and think it will all fit right into the factory replacement without rubbing or a difference in scrub which might wear the tires wrongly. The current tires are in there just under the fender lip with little room to spare, which is a concern too.

I don't know anything about being a mechanic, but am trying to learn as I go on the Jeep - so will this combo get me what I think it will or will I end up wearing the tires wrong or it end up not fitting under the fender lip or rubbing somewhere else?

The offset difference is negligible. The new tire will be an inch taller and the same width. Your scrub radius isn't going to be impacted. You may possibly rub when you turn at full wheel lock.

Thanks for the reply, it really helps me understand if I'm on the right track before plunking down a chunk of change!



Let's say I load this config up and it ends up rubbing at full turn, can I just then add a 1 or 2" lift to compensate? Or would I need something more involved?

The place it is most likely to rub is the plastic air dam (plastic piece that connects under the front bumper). The air dam can easily be trimmed or removed. Nothing else needed.

Other places rubbing is semi common is the lower control arms and swaybars. There are a couple ways this can be avoided the most common being adding wheel spacers. You can also adjust your steering stops or avoid turning the wheel all the way. All of this can be avoided by selecting wheels will 4.5-5.0 backspacing with those sized tires. The wheels you are looking at have 6.0-6.25 backspacing which keeps them tucked in closer.

Adding a lift wouldn't do a lot for rubbing while turning. It will help if the tires rub the fenders over bumps and such.

None of those sound too terrible, but sounds like I'll look for wheels with a bit lower backspacing first, like you suggest, to make things easier and avoid spacers. Thanks for explaining it, really helpful!
