Brake and tire Question

Yes, there is a proportioning valve in the lines. It is unusual to hear about it going bad though. Usually something is physically messed up back there or you have a blown axle seal leaking stuff onto the drum.

I would open it up to be sure. Some inspection folks are lazy....

We had P225/75's on our 88 and it had great traction in the snow and off road.

We went to P235/75's and were extremely disappointed with the loss of both winter and wet traction as well as off road. We lost about 10 mph on the highway in the snow and it spun tires on takes off much easier. I mean by 'lost' the steering starts to 'float' 10 mph lower which means you can hold up transport trucks. :-(

The sticker in our glove box also indicates the largest tire for our Cherokee is listed at P225. Yours might be different.

A good clue is to look at the inside of the rim. If it's coated in crap while the other wheels are clean, then it's a good bet that wheel has a fluid leak somewhere.

I had the same issues with my YJ when I went from 225mm wide tires to 235mm wide tires. I don't recall how much sooner it started to float, tho.

It's anti-intuitive, but thinner tires are better for snow because they let the car sink into the snow to give better traction. And when it's wet, there is more surface to hydro-plane on with wider tires. It's the exact opposite of what you want when it's dry, where you want a bigger patch of rubber on the ground.

It's not at much infighting as it is full blown kookout. Killfilters work well for keeping the noise level down.

Infighting? There's no infighting here for anyone who makes effective ues of a killfile. It shouldn't take you more than a day or two to learn who to plonk, then the group becomes a much nicer place to visit!

It helps to use a newsreader that allows scoring but even with Outlook Express you can still eliminate most of the noise.

As well as the other suggestions, sometimes an obstruction will lodge in a brake line (usually a broken piece of lining from a flex line), which can be hard to diagnose.

I'll agree with others that that may be too big a tire, but the symptom you describe can probably be mitigated by lowering your tire pressures in the rear.
