15.5 inch wide tires on a CJ-5?

I was looking at the TSL-sx 33\15.5 and i was just wondering if they would fit on my 73 cj-5. Of course i am putting the 4 inch lift on it. Would wheel spacers help?

Putting wheel spacers on a vehicle puts a ton of un-due stress on your axles, U-joints, and gears. It makes your steering hard to turn....which stresses your steering gear box. Wide tires are hard enough on everything....let alone wheel spacers. That's the main reason most people that put large beefy tires on...end up upgrading to bigger axles....lockers....hydraulic ram steering, etc. You might consider a smaller tire....or plan on spending a ton to upgrade everything else. It all depends on your budget. It might look cool to have huge tires....but it's not too cool to be stuck on the side of the road with snapped axles or busted u-joints.

I run 35x15x15 TSL's on my71CJ5. Granted, I'm running a SOA Dana 44 front axle that's 54" wide but my rear axle is the same one that you're running (stock Dana 44 50.5" wide I believe). Instead of spacers, maybe you could run some of those Rock Crawler rims (15x10 with 3.75" backspacing). They might allow you to get away with those tires without spacers. Of course, there's always the 33x12.50 Swampers that still look great and kick butt offroad.

I just put 37 x 13 x 15 TSL Boggers on my 1980 CJ7. I have some rub and have just ordered 2 1/2" spacers form performancewheel.com. I think it will help but I don't think that 15.5 will work if you do any off roading at all.

I think that you will be a lot better off with those tires. You say that they are 13" wide, is that 12.50 or 13.50? I had 33x14.50's on and they would rub the springs when turning. There was no rubbing when driving in a line. However, they did handle awful on the highway. they were bias ply and they were wide, and they would track wherever they felt like. I personally will never run wider than 12.50 on a rig that sees street time. that is just my personal opinion. By the way I am running 4.75" backspacing on 10" rims.

I really dont see the difference in spacers and offset rims besides the spacers have more stress on the bolts. How much extra would offset rims cost..personally i think the wider stance looks cooler but whatever is better.

Stress

I checked on some offset rims. A friend of mine owns a tire store and he talked me into the spacers. The off set rims put undue stress on the rim because the center of the rim does not match the center of the tire. On serious off roading, this can cause the rim to get stress fractures.

does anyone do there homework?

I would really like to know where all the rednecks get there ridiculoous information?

Wheel spacers are not different that offset wheels. It just depends on how much money you want to spend.
First- offset wheels are built to be offset, they are not weaker because of this offset, I talked with several manufacturers before buying mine.

Second- the offset does not change the center of the wheel. The center of the wheel, is still centered with the tire. It reduces the back space so the wheel is moved outboard.

Third- the size of the tire only effects axle / u joint breakage if you have alot of horsepower- 300 plus, which most I-6 jeeps don't have.

Fourth- what will happen is you will wear ball joints quicker. This is due to the increased torque arm created by the reduced offset. Kinda like putting a longer rachet arm on to get more torque. So, put in heavy duty ball joints and the 4 inch lift, and get a 12 inch wheel and the 15/15.5 tires. I have been running that setup for 3 years now. No problems.... rednecks... can't live with, can't trust there information...

They are generally not any more. Just ask the people where you get the rims their options for backspacing. with that wide of a tire, if you go with it you would want a 10" rim, which you can also use to run the 12.50's. If you want a tighter bead then you could go with an 8" wide rim. The width of the rim will limit the amount of backspacing to some degree. I don't think you can go much lower than 4 or 3.75 backspacing with a 10" rim, but with an 8" rim I think you can get down to 3". Hope this helps.

If you think about it for a second... If the backspace is built in the rims then the center of the tire is farther outside of the mount. It doesn't matter if you are a redneck or not. Think about it for a minute. Plus it figures that the person you are buying the rims from or that makes the rims will tell you their product is the best way to go. I got my information from an independent dealer that by the way lives in the Northwest (WA State) and he lost the sale because he was honest with his info.

Jeeba,
The v-8's that Jeep put out didn't even have 300+ horsepower....let alone the I-6. The larger the tire size....the more stress you put on your axles & U-joints. Horsepower would definitely do the same thing...I'd agree. If what you are saying is true...that the tire size doesn't cause any stress on axles....then the axle splines of all AMC 20 rearends would be sufficient for larger tires....and Superior Axle would be out of business. I've been in my share of jeeps with oversized tires....33's & 35's mainly....that have twisted axles, blown u-joints, blown lock-outs, etc.....and I can guarantee you that they weren't OVERPOWERED!!! It's a good thing a redneck stopped to pull us home.

Partially agree

I will partially agree with you, I have three jeeps, and by the way, AMC did make the 360 and 401 which did have over 300 horse out of the box... I didn't say it was in the jeep... the 304 only put out 215 - 225 hp right...At any rate... the axle breaks and u joint breaks don't occur when your driving down the road... they happen when you don't know how to drive your rig. You get stuck, you panic, or you get axle hop and you don't let off the go juice... that is when the breakage occurs... I can send a line to how offset wheels are built if needed?
