2012 JGC X with SRT reps installed

I upgraded my '12 X (18x8 - 265/60 18) with SRT reps in 20x9 and went with Hankook 295/45 20 for tires. My biggest questions were would they be too wide and more importantly would it really work on a 20x9 wheel. I was back and forth on this, but ended up going with the 295s as they were closest to original tire size in order to keep the speedo close.






I love the look, but my first thought was, "Oh man, I went to wide." I have been told rubbing was not an issue and so far I have yet to see any problems. They are growing on my though and friends all say they really like the look.

Overall I am happy with it, but there has been a learning curve when it comes to driving with this much rubber on the ground. For example, I picked it up and while on the highway there was a distinct pull to the left that I noticed. Thought it was an alignment issue so took it back, but was told the tires will follow the road a lot more now and with older highways having more of a crown I would notice it. I wanted to call BS, but on side roads there was no pull. I then drove in the right lane on the same stretch of highway and it pulled a little to the right. Hmmm. In the past few days this stretch of highway has been repaved and the crown is much less and I don't see the pull anymore. I also feel a little vibration in the wheel and seat around 70mph from time to time, but this is hit or miss.

In any case the Jeep is a lot more planted now. Tighter feel in the steering wheel too which I like. When cruising at 75mph I would feel the Jeep float some around turns and always ended up slowing down. I can now complete these same turns without having to tap the brake.






Here's to a fun Summer.

Looks great! Definitely a more aggressive look than the stock wheels.

Re: 2012 JGC X with SRT reps installed

That Looks excellent.

as for the pulling to the left or right depending upon the road conditions... it's not BS, it's called Tramlining http://www.tirerack.com/tires/tirete....jsp?techid=47

I deal with it on my Mustang running 275's up front, I'd imagine a 295 is even more pronounced. You'll get use to it

Re: 2012 JGC X with SRT reps installed

Thanks everyone. Especially for the Tirerack link.

I am really liking this setup. I am still getting used to how it drives, but much more fun now.

I will say the engine really seems to work more on getting the jeep going now. It stays in a lower gear longer when accelerating and I feel the jeep slow down more when I come off the gas. Thus resulting in what I think is easily a loss of 1.5 mpg if not a little more. This goes for highway as well as city roads.

Still trying to figure out the proper tire pressure. When they were installed they inflated to 37 psi and they seem to fluctuate between 33 psi in the early morning to 37 late afternoon during hot temps.

Re: 2012 JGC X with SRT reps installed

Like the look. My rims are corroded (posted in another thread) and not being covered under warranty. Found some good deals on 20" wheels, just wondering anything need special need to be done to go from 18" to 20"?

Re: 2012 JGC X with SRT reps installed

Looks good!

what offset did you go with? I see that there are a couple different offsets made in the 20x9 size.

Re: 2012 JGC X with SRT reps installed

Hey Skroll:

I am glad to see you picked a good tire and wheel combo.

You should also play around with the tire pressure to see if helps with eliminating the tramlining sometime going up 1 psi will help with steering feel and lessens the likelihood of tramlining in wider tires.


rigth now I run 36 psi in my front tires and 37 psi in the rear. for some reason it helps the truck spring off the line quicker, so I don't have to dip into the pedal as far.

Re: 2012 JGC X with SRT reps installed

AJS800 - These are 34mm from 20x9 OE Replicas 2012 Jeep SRT8 Hyper Silver Dark 20 inch Wheels at Street Dreams

Nubby - Nothing special was done. New wheels, tires, TPMS and lugs. simple swap. I am going back to the 18s in the Winter so I am not changing the brake size at all.

Jeep_Add - Thanks. I am playing with tire pressure now. I do find that they TPMS reads anywhere from 33-34psi first thing in the morning when it is cooler and then rises to 36-38 when things heat up during the day.
