So my Cooper Discoverer ATRs **** the bed on me after 35K miles and three years, one of the tires sidewalls was cracking all around near my wheel, looked like dry rot cracking, makes me wonder how long the tires sat at the place I had bought them from before they put them on my truck.

Anyways, went to a different shop yesterday, one I had been using for awhile now. Got myself a set of the new Continental Cross Contact LX20, nice looking tires, ride nice and smooth.....at least they did when I first left the shop.

I noticed last night and today that at about 70 MPH, I'm getting some shuddering. Not violent shake the steering wheel out of my hand shuddering but noticeable shuddering nonetheless. Last night I thought maybe it was the highway I was on but not the case. So after I get home from work, I checked the pressures, all hovering around 35PSI. I then checked my lug nuts.....both front and rear driver side wheels had one of the five lug nuts loose, hand loose, bad. Tightened everything back up, passenger side was all tight but they stripped one my nuts with the gun, can't even get my lug wrench on it and the chrome cap is loose.

So I hit the highway again for a test run. The shuddering is still there some at cruising speed but not as bad as before. But now it just feels at all speeds that they just aren't riding right, the truck is riding harsher than it was when I had the ATRs on.

Any thoughts?

1) bad balance job?
2) wheels aren't properly seated on the hubs?
3) I have a bad tire or tires(s)?
4) some of the above?
5) none of the above?

I'm gonna go back first thing tomorrow morning but curious what everyone' thoughts are.

I always look at the date code on tires I've bought to be sure they didn't spend their best years on the shelf. Once they've reached nine years, supposedly they're gone.

1 - Could be bad balance. Some tires are harder to balance than others for some reason.

2 - Wheel seat on the hub is possible, but would seem unlikely. Sounds like you had a wrench-puller, not a technician mounting the tires/wheels.

3 - Could be a bad tire or tires. One or more could be out-of-round.

I'd say you might want to have the run-out on the brake rotors checked. Not sure what you call a "shudder", but my Ram had an annoying shake at certain speeds. The rear rotors were out. Once I had them turned, the shake went away.

If it shaking at 70 likely the balance on the tires it may have tossed a weight if not correctly hammered on to the rim as for the lugs no excuse there and they probably used a 22mm instead of 7/8 like you need to or the lug caps strip out rotors may be warped if you hit brake and then it shakes

Check all of the above and while you at it give the u-joints a look they can come out of nowhere

So I went back to the tire shop first thing this morning. After a rebalance and recheck of all wheels the problem persists and seems to be getting worse. They did another road test with me and felt it coming from the rear. They moved the backs to the front and vice versatile and road tested again and still there. They put it back up on the lift and spun it up in the air and you can the rear driveshaft wobbling under load. Wheels spun beautifully but can see the driveshaft wobble. I'm now at the dealer as I have about 5K left on my drivetrain warranty. I now await their diagnosis/verdict.
