Can i put 235's on a stock MJ 4X4

 

1986 Jeep Comanche X long bed 4x4 2.8V6

Yes, I thought all MJ's came stock with 235's. You can put 30's but they rub slightly in the front when steering sharply.

some 30s might rub. I had 30" bfg ATs on Jeep alloys and they never made contact.

No MJs (or XJs) came stock with 235s. Early MJs and XJs came from the factory with tires ranging from 195/75-15 to 215/75-15, depending on model. Later the factory increased the tire size, but the largest they ever offered on the MJ was 225/75-15, and on the XJ either 225/75-15 or 225/70-16.

been running 235"s on mine since I bought it in '98

When I bought mine it came with 235/75R15 tires on stock 15x7 rims. The first set of new tires I bought for it (which I run on Booger right now) were the same size, and on both of them they rub (but just barely) on the lower control arms under full lock steering.

My MJ and my old XJ both had 235s on them when I bought them, and I have worked on many stockers with 235s.

I fully agree they didn't come with anything bigger than a 225 from the factory, just look at the door sticker, but it seems many folks opt for 235s when replacing them. Maybe it's just because that is a very common size, cheap, and easily found at any tire shop :dunno:

 

As far as the rubbing, if you encounter issues, just adjust your steering stops on the knuckles so they can't rub. It will be a minimal amount, and better to lose a tiny bit of turning radius that eat your tires up on the LCAs.

 

Another option for the rubbing would be to run WJ LCAs. They are bent to accommodate larger tires and boxed for strength. They are pretty much a direct stock replacement, but some grinding on the bushing sleeve may be necessary. However this is probably not worth the effort unless you really need that extra little bit of turning radius.

I had 235's on my canyon rims (and they do not rub at all), however i put in 1.5" spacers to make the truck less goofy but still retain an OE rim, then i went with 31's. I had to trim about a 3/4"x1" of the inner fender flare at the bottom to keep them from rubbing the flare (they do not rub the control arms with the spacers) but then again this parts getter doesn't leave the pavement. And yes the tires / rims are worth more then the truck.
