15's on a 2015 JGC Summit?

Sorry, I am a bit of a noob to this stuff but, is there any reason I can't put 15" wheels on my 2015 JGC Summit Diesel? It has the Quadra-lift suspension. I am not even sure if I would like the way it looked but I was just wondering if it's even possible...

I don't think you could put 17" on the V8. I believe they come with the bigger brakes.

Yeah it is for a diesel. I guess 18's would be the safe bet then. I am just torn on whether to just throw more aggressive AT tires on my factory 20" wheels for both daily and off road use (the drawback being worse gas mileage and them still not being all that capable off road) or buy 18" wheels and put some really aggresive off road only tires on them and keeping the factory wheels and tires for daily use and just using the 18's when I make an off road trip (the drawback here being I don't get the look I want on an everyday basis and having to change tires when I want to go off roading). Or I could just do both...

Then what i would do is both. Keep the 18's with an at on them and run a 20 for the look when your on the street.

The option of tossing at's on the 20's is there but you may take a slight hit to ride quality. At's usually have a pretty solid sidewall to keep the tire from comin off the wheel when its aired down some. Id run the 18's for that

You pretty much nailed my thoughts, I've been debating for about a year now the same questions. I currently have the stock 20s on my 2014 Liimited. I've gone back and forth mainly looking at members experiences who have gone one way or the other.

If you keep the 20s you could go up to 275/55/20 and you'll get more tire, but some have experience rubbing and/or added a leveling kit to the front for a little extra room. Right now I'm leaning toward getting a second set of wheels and 265/65/18 tires. Gives you a little more rubber than the stock 18s but will leave some breathing room. If you invest in a few pieces of equipment it will probably be quick and easy to change from one set to the next when you want to.

But then I see something like this and it makes me rethink things. This car I'm pretty sure is running stock size wheels, but in a more aggressive tire and it appears quite capable off road. Although you still might not get the look your after.

You can also go with a 285/50R20. No rubbing has been verified by many members.

Yeah, it is a tough decision. I don't believe I can do the leveling kit because I have the Quadra-lift suspension. I was thinking about getting the Duratracs if I decide to use the same tires for daily driving and offroading and if not then I was thinking about some type of mud tire with 18's. Like I said ealier, I could always just do both but I think the Duratracs would do fine offroading. I think I am just going to have to set up a picture of each tire on a wall and do a blindfolder dart toss to decide, lol.
