I’m assuming anything in the 195-225 range will be fine, given that’s what they came with. Wasn’t sure if the weight from a heavier tire in that size range would affect anything, specifically acceleration with the smaller engine. My neighbor has a CJ8 with a 2.5L and the tire shop talked him into putting on the biggest KO2s (31s or 32s) that would fit. A month later they were sitting in his driveway for sale. He said he regretted going that big and lost all power.

I see you’re sporting a wheel chock in your original picture! I do the same with mine. It tends to not want to stay parked, specifically on any incline. Anyone else have this issue or a solution to keep it from rolling away?

Time to replace the current tires on the MJ and wanted to know if I’d see a significant loss in power or potential axel/driveshaft issues. Current tires are Toyo Eclipse P205/70 R15 with stock steel 15x6 wheels. Wheel and tire weight 40 lbs. I have a stock set of alloy 15x7s that weigh 22 lbs each. I am considering the same size tires or 215/70 R15 on the alloy wheels. Depending on if I go all season or all terrain, and the size of the tire, estimated weight range is between 44 and 50 lbs. Any issues moving up to the bigger wheel, tire, and additional rotating mass? I know it’s very minor, one size up on both the wheel and tire, but once they’re purchased and on the truck, I’m stuck with them. Do you recommend staying at 40 or will I be fine at 45-50 lbs.? I have the very desired 2.5L, 2WD, 4-speed manual with no power steering! Current setup is “peppy” for being the 2.5L. I drive the MJ about a dozen times a year. Given my location, you must use the interstates (65 mph) to get from point A to B. Thanks in advance.

My original thought was between $4,000-$6,000. It seems like the majority are throwing out the same range, which is helpful. Thanks for the input.

Location is WA State.

I was thinking $4,000-$6,000 rang and was also considering the swap.

I’m considering selling the MJ to pursue a CJ8 and wanted to get your advise on proper value, given that Kelley Blue Book and NADA will value it worthless. I know that the right buyer would pay what it’s truly worth and looking for your help. It’s an 89 SporTruck, 2.5 L, 2x4, short bed with a 144k miles on it. It has a 4-speed manual, no power steering, and is all original. The body is straight, no rust, runs strong, and has a small golf ball sized dent on the body near the rear bumper. I know a 2x4 with a 2.5 L is not desirable, but it’s still an MJ with potential. Thoughts?

Safe to say you gained 3 inches in the back? What did you use for shocks? Would you say the kit you put together is cheaper or better than just buying a kit?

General Spring sells a 5(3/2) leaf, 1700 lbs capacity. Anyone know what kind of height increase you’d get? Or is there a better option?

No off roading anytime soon, it’s a 2x4. The goal is to eventually make it a 4x4. So for now looking for height, but at the same time, not wanting to buy things twice if and when the time comes to make it a 4x4. Are there any 3” kits that offer a new leaf pack or are all AAL? I’d prefer to get all new springs. The bed of the truck isn’t leveled, so I’m assuming it’s time to start replace things.

I want to put a 3 inch lift kit on the MJ to give it a little more height and have come across a few kits that don’t appear to be on the forum. I do see Rusty’s a bit, but most are going with the 4.5” kit. Do any of you run the following kits, do you recommend one over the other, or do you recommend a kit that I haven’t mentioned? Rough Country 62530 3” Suspension Lift Kit Skyjacker JC305BPHLT 3” Add A Leafs kit Rusty’s RK-300AL-MJ 3" Add-A-Leaf Kit Thanks in advanced.

So safe to say the coils gave you about an inch lift? Do you know if the shocks would fit? What size tires did you run on it and was your 89 a 2.5L?

Did you use the shocks as well? What did you do for the rear?

Does anyone know if JKU springs and shocks will fit a MJ? I have new, stock 2018 JKU parts sitting in the garage and want to put a lift on the MJ, or at the minimum, replace the worn out parts. Obviously I’d need to add a leaf in the rear to gain any lift. Was wondering if anyone knows if these will fit and if it so, would I gain any height? Thanks in advanced.

Do you guys have the "p" rated 215/75/15? I'm assuming you both have the wider wheel with the 4.0?

It looks like the max tire width on a 6” wheel is 205. If I went with a wider wheel, would you go 225 or 235, or still stick with the 215? Would you go with a “p” rating tire to save weight?

I have the OEM 15” x 6” steel 9 slot wheels.

I should also add that the MJ doesn't have power steering, which isn't a big deal once you're rolling. But trying to parallel park is a workout!

How much would a typical donor XJ run along with things that needed refreshing? I'm assuming this would not include an inline 6.

I’ve thought about making it a 4.0L, 4x4, with a 5 speed manual. Just don’t know how much that would cost, time, and if it was worth while. If I did go that route, it would be years down the road.

Shooting for the off-road look. I guess I wouldn’t need a true off-road tire for a 2WD. I do need something that will grip though. I have a steep, shared driveway that is a ¼ mile long, requiring one vehicle to pull off the road to allow the other to pass. It doesn’t happen often, but I have gotten the MJ stuck in wet grass on the driveway. So I’m looking for something that will grip when it start raining in the Puget Sound. Any reason to go bigger than a 235/75/15 or 30/9.5/15 with the 2.5L, or is it pointless? If I’m stuck to that size, I guess a lift would be pointless as well? Again, would like to sit a litter higher off the ground and not sacrificing power if possible.

I have 143k on the 89 SporTruck.

I currently have 205/70/15. I love the KO2's on my wrangler, but they are a heavier tire. I was considering 235/75/15 or 30/9.5/15.

Need a new set of tires for the MJ. It is a stock 2x4 with the 2.5L, 4 speed manual transmission. Wanted to go with a bigger tire and possibly a small lift to sit a little higher off the ground. At the same time, this is a 4 banger 2x4. I’m not trying to get crazy and lose what power the 2.5 has. Any recommendations on tire size and lift?
