Jeep Cherokee Tire Upgrade – Project XJ Overland Ep. 6

In this video we install our new Cooper Discover STT Pro tires on our project 1999 Jeep Cherokee XJ Overland. We went with a 32×11.5×15 and could not be happier with the aggressive look. Check out the video for why we decided on a 32″ tires.

  1. Great project to do with your sons! The 32's look fine. Did you offset the wheels out or did you have enough adjustment on the wheel – stop bolts to avoid the inner fenders? Did you have to reset the wheel-stops to avoid bottoming out too? When you finished, how much suspension travel remained and did you avoid the tires rubbing on the trail?

  2. Just bought my 17 year old a 99 XJ, exactly like your Overland Project…for $2500! (He loves my JKU so it was an easy purchase) It's in the same shape as yours and it is totally stock too. Same steering shake at 55mph. Balanced the tires and ordering the sway bar bushings as we speak to get started on chasing the wobble down. Overland Project is a great series and we are actually following your progress quite closely. Keep it up!

  3. what are the wheels? They look like they are 5 x 4.5 bolt pattern but I was wondering the width and backspacing? I'm looking to get new wheels for my rig and wanted to know the exact specifications.

  4. Thanks for the video. I have been looking at a myriad of lift kits from RC to Rubicon Express. By the upload date you have not had this long. What are your thoughts on the various lift kits, where did you get yours and how are the wheels and tires working out. I have a stock 01 XJ and would like to get mine looking like yours. I don't want to beat it up on rocks but would like to do some rough trails. I am am on old guy in his sixties and after my third Jeep would like to do something special to it. You can check my stock XJ out on my channel. It is my second one. My daughter has the CJ7 now. That is on there too. Just search for it.

  5. Great video, brother! Thanks so much. Very informative and helpful. I own a Glacier Blue '98 XJ (stock) just like yours and this was immensely helpful to visualize what mine will ROUGHLY look like with a 3" lift on '31s. I also was stoked to see your trim and bumper corners painted black since I was thinking about doing that on mine and was curious of how it'd come out.

    Keep on Jeepin'!!

  6. I am hoping to ask you a question. I know you have a lot of experience with tires on the XJs. I'm considering a 31 on a 3 inch lift. I don't want to loose drivability. Do you have any experience or advice on how stock gearing would handle 31s? Any advice would be awesome. Love the channel.

  7. I have a 1992 Jeep Yj with a 2.5 4 cyl it’s my daily driver and live in Connecticut and I was wondering if 32’s cooper stt pro will be over kill or too slow I think 33’s are too much and 31’s are eh so I’m thinking about 32’s but does anyone have experience with this size tire and with a small 4cyl engine
