I know that 275/55/17s will fit my R/T all around but my question is how will they look. Will they look too wide for the rim? From like a head-on profile, will the sidewall be like bulging over the lip of the rim? Thanks for the info.

Awesome! I'm gonna get the Yokohama ADVAN S.T.'s in 275/55/17 all around. I'll let you all know how I like them.

275/60/17 is stock on the Durango R/T with the same rim.

The 275/60 gives you a nicer ride too.

I'm not sure how you guys came up with these numbers. I presume that if you're worried about the tires being too wide, you'd also be worried about them being too tall, right?

The stock tire is a 255, which has a diameter of 28.0 inches, MOL. Going to a 275/55 gives a diameter of 28.9 inches, while a 275/60 gets you a 30.0 inch diameter. Thats a pretty serious change where your gears and speedo are concerned. The 275/60 will cause your speedo to be nearly 7 percent out of whack. Remember that the aspect ratio number is a percentage of the width of the tire, so as the tread gets wider you need the aspect ratio to go lower.

If you want to stay close to stock, try a 275/50, which will give you a 27.8 inch diameter, or a 285/50 with its 28.2 inch diamter. Both are just 2/10 of an inch off stock, which is a lot better than a full inch. You'll be within one half of one percent of a true speedo reading then.

No, not really. I can deal with the tire height by using my SuperChips. Tall tires can "look" fat compared to a lower profile tire even if they are the same Section Width. To some people "fat" is the Sidewall Aspect Ratio.

What are you running for tires that gives you a 13% error?

So if I go with 285s, will I have any rubbing issues?

Also, if I choose to go with an 18" rim, what sort if size tire would be optimal to stay as close to factory specs as possible? 285/45/18? 275/45/18?

Thanks in advance for the help.

Who makes a 285? It would likely depend on the profile. The only problem I have with the 275/60's is turning lock to lock. The tire will rub slightly on the frame. Most likely a 285 would be a little bit worse.

I'm having a hard time finding a company that makes a 285/50/17 so if I stick with stock rims I'm going to buy the Nitto 450 in a 275/50/17.

like guy said, 275/50 for 17's nittos are a good choice. I road on 28" 295/45r18 nittos 555 for a while and liked it alot. I have also had 255/55r18 and 285/50r18 amd 255/45r18
nowi ride on 275/45r18. I have pics of all if you would like to see, the pic by my name is 295/45

the tires should match the wheel well gap

Yeah I was gonna say something if you were still getting the 275/55's..... Way to big IMO..You'd end up with a bubba tire look.

275/50/17 Nittos are awesome. Ive had mine for a year and have absolutely no complaints. Heck they even hook decent at the strip.
