There's an android app for free out there called tire calculator that will allow you to put your original and new tire sizes in. Then it compares the differences and tells you where you are changing sizes and will even tell you how much it will throw off the speed by. It gives a recommend or not recommend as well.
Your radius is .7 inch bigger and your speed will be off 3.7 mph. Your tread width is .4 inch bigger as well. Some quick looks at your Jeep with the wheels turned should tell you if its close. It shows not recommended but I think that's pretty conservative. You may choose to get some wheel spacers to help out...not sure if you would need them.
Thanks Skipper6413...I've used the tire calculator and I love it. I'm looking for some real world experiences. Like...would the tire rub the upper fender lip if it gets stuffed while off-roading? Or would the tire hit the front/rear fender while making turns? If this isn't the right size tire...What is the largest size tire I can run without having issues (or keep the issues to a minimum). I'm currently running the factory 17" rim. Thanks for any help you guys can give!
