YJ Tire/Wheel Fit Check

OK I am getting ready for wheels and tires on my 1990 YJ Laredo, and need advise on picking the correct size for a NO LIFT Jeep. Let me know your thoughts....
I currently have NO LIFT, the stock alloy Jeep wheel, with a 235/75/15 tire, which works just fine.
I am going to change to a steel wheel. Here is what I was thinking.
15x8 steel wheel, with 3.75 Backspacing
With a 30/9.5/15 tire (Will this work without any rubbing?)
OR
15x8 steel wheel, with 3.75 Backspacing
With a LT235/75/15 tire (Will this work without any rubbing?)
Any advantage or disadvantage on either tire size?
Any advise would be much appreciated.... Thanks

31x10.5 will fit on a stock wheel and no lift. Thats what my dads yj is set up with now. He doesnt wheel much so not sure how it is off road. The po of my jeep changed to aluminum wheels so im not sure of my backspacing but as far as clearance I've had no problems with my 31s. Neither one of us have lifted our jeeps and my springs are a bit worn from the last 25 years.

Depends on what you are doing with your Laredo. If its a street machine then the 30/9.50/15 tire will work just fine. If you take it off road, then at some point they are going to rub. That tire is about 2 inches taller than stock as well as 2 inches wider.

A 215/75/15 is the stock size, so the current tires 235/75/15 are actually a little taller than stock. I have even seen some that run a 245/75/15 which are equal to a 30" tire in height but narrow like a stock tire. It's just a tough size to find a tire of your liking in.

My jeep had 30x9.5 tires when I got it. With no lift. And I never got them to rub off road. I did have the sway and track bars on though.

^^ I can confirm that. I had 30 9.50's on stock YJ spoke wheels, no lift & they never rubbed off road.

Actually they were a pretty good fit for a bone stock Jeep.

I'm sorry. Apparently my version of off road and everybody else's is totally different.

When I say off road, I don't mean going from the pavement to a dirt road. I mean more like take the dirt road a few miles and then just turn left (or right) and make your own road. Maybe run an old tram road or a deer path. You know adventure.

Sometimes you might encounter mud, or slippery clay, or play in an old stone pit. Off camber situations that get your butt hole gripping the seat cover.

In those situations you will get tire rubbage, on anything but a stock tire. It won't rub the inside but if you flex it enough it will scrub the flare on the back side of the front tire.

My cousin stuffed some 31x10.5's on my Jeep before I bought it off him. They rub slightly when steering at lock.

i have a 4 inch lift bigger shackles and a body lift and i can rub my 31s if i have to get flexy they mistake off road with wheeling if you dont want body damage stick with stock tire size a lift is cheaper than a bunch of body damage when your tire eats your fenders

The 235/75 is basically 29". You should be able to go 30" with a stock Jeep. This is based on the fact that I ran both of these tire sizes on mine before I lifted it.

I personally wouldn't go more than 30" in your situation. Unless you are thinking about lifting it later. Then you should get larger tires now, and not buy 30" tires now, and 32" tires later.

A 2" Lift and 31" tires looks pretty good. Again, I had this combination for a while. After a 1" body lift, I'm now on 32" tires.

I can assure you, I beat the dog sh*t out of my Jeep back in the late 90's. Our versions of off road are the same. There was no rubbing & I twisted that Jeep up so many times the tub was tweaked. The Jeep was 3 or 4 years old at the time so the springs were still good. If the OP's springs are sagging a little, then yes, he might rub.

If you can find a tire that meets your needs, with out going to an LT type tire, the P is a much softer tire and will ride and flex better, but the p will have thinner side walls, it's all in what you need. P= passenger car {what a jeep really is}, LT= Light Truck, they will load range C,D or E, they also weigh more, ride rough, take more power and get less MPG. FACT!

30x9.5 are the perfect fit for a stock "YJ"
