I need new tires for my Wk with 20x9 SRT REPS with WK Eibachs and srt bilstein shocks. I want a long lasting tire the Yoko Parada spec x i have now are not lasting, I got 15k out and got rough ride noise wear. What will last long time ride somewhat smooth.

I got the Sumitomo HTR Sport H/P on my reps. 25000 miles and still has a decent amount of tread left. I got 275/45/20 all the way around.

Re: Best tire for 255/45/20 or 275/45/20

Any other thoughts on other brands that would be good? I will be purchasing new wheels/tires for my 05 GC Limited in the next couple of weeks and would like to go with SRT8 replicas. I can't decide between 255/45/20 or 275/45/20 on all fours. I keep getting mixed reviews. Some say the 275s are too big for the front and others say I may need to grind a bolt or do a little trimming. I have even heard others say going too big may cause transfer case issues. I would really like to get your thoughts on any pros/cons to this setup. Any reason not to go as wide as 275? I live in Indiana and this combo will be both my summer and winter setup at least for the first couple of years. Any insight you can give me would be greatly appreciated.

I have bridgestones 255/45/20R changed them at about 55000 kms and still had some tread left. My setup is SRT rims, SRT springs but stock struts. I will soon replace the struts with Bilsteins B6.

Its a lovely street drive with the 255s and i have no issues so far with moderate consumption.

I blv that with the 275's - apart from other problems that you may face - you will have higher consumption unless that does not bother you.

Thanks for the feedback Connie! The SRT8 wheels look great on your Jeep, I have the Black metallic too. I think I will probably go for the 255s.

Re: Best tire for 255/45/20 or 275/45/20

I have the SRT8 Reps ordered and on the way and now I am down to deciding on the tire size. This will be a matching set for year-round use in Indiana. I am trying to decide between 245/50/20, 255/50/20, and 265/50/20. I'm not worried about the 245/255's but I haven't found a direct answer on whether or not the 265's will fit without clearance issues at full travel. (I will not be trimming the bolt.) Is anyone on here running 265/50/20's on front of 2005-2010 GC with no issues? I have searched several threads but keep getting WK2 results.

Any insight would be greatly appreciated!

I'm running 295/45-20 rear and 265/50-20 front, SRT reps 20x9 F 20x10 R, even though yes they are about 1 inch taller then the stockers (245/60-18), the fronts and rears are close enough compared to one other that I have had no problems, And (NO) you will not have to trim the shock bolt


The tires I went with are Toyo Proxes STII

I've been to several places to get tires for this same setup and told each time that this would not work because it would cause transfer case issues, issues w/ 20x10 set rep rim not fitting and sticking out too far, can not rotate tires and finding a set of tires to fit both rim sizes. 2010GC, you said you had no probe, can any body else chime in who has the same setup? I have 08 w/ 5.7 engine. Sorry to break in on old thread…just trying to get a good answer.

Re: Best tire for 255/45/20 or 275/45/20

Yes, you are correct in saying that you can not rotate any of the tires due to being wider in the rear then the front, and to top it off u can't even switch them to the other side because they are directional. But I only run this set up in the summer time so they dont get to many miles to were I need to switch or rotate them. As long as the front and rear tires are no more then 2% difference in height from each other you shouldnt cause any problems to your transfer case (I had the same concern). As far as the rear 20x10 sticking out to far, thats false, they are off set correctly from the manufacture just like the stock wheels that come on the SRT Grand cherokee, ( I believe the fronts are 38 and rear 50) dont quote me on the off sets, But there what ever came on the stock SRT's
