I was thinking if you don't have a friend to swap tires with you could try rotating your tires, maybe front to back, to see if that makes a difference.
it means breaking the bead on the tire and rotating the tire on the rim 180..really a simple thing to do at any tire shop.

I think he means rotate tire 180 deg. relative to rim.

if you really want to do it right find a shop with a Hunter brand tire balancer with a road force option..it tells the installer where the high and low spots are on the wheel and tire and how to match the tire and wheel so that it will cancel out the difference between the two.

All good ideas. Remember, it just needs to be the same bolt pattern on a 15" rim for the loaner set of tires, the actual design and brand doesn't matter, so we're talking Camaro/Firebird. Olds Cutlass, Buick Regal, etc...

I would imediately look at the driveshafts if that doesn't fix it, especially since you feel it throughout the car at a specific speed, and rotating the tires front to back didn't change it, right? My Mustang had an out-of-balance driveshaft and it did exactly what you describe at 70 mph. OK at 60 and 80.

Update for the record:

Turned out to be bad idler arm. Replaced idler arm and pscv and wobble is all gone. Should have realized earlier but at least mystery is solved. Pretty sure pscv had nothing to do with it but needed to replace anyway.

I'm having a similar problem. I have searched and found that a local tire store has a machine that will actually shave the tires on the rim and I believe on the car. I'm going to give that a try.

180 the tire on the rim only works when a tire balances out with a lot of weight
