I had a rear tire blow-out on the freeway this morning on my way to work and didn't realize it until it was too late. The tire is shredded and needs to be replaced. I'm not sure how long I was driving w/ the flat but the tire mark after I parked on the side of the freeway appeared to be ~25 yards.
When I put on the iddy-biddy spare tire and tried to drive off w/ it, the spare tire was wobbling that the tow truck driver recommended I tow it to the tire place to prevent any damage.
What could be causing the wobble? I hope it's the spare tire and not the shaft or axle of the car. The replacement tire is on it's way from the warehouse and should be installed before 5pm.

 

Do you have aftermarket wheels? The spare could of been installed with the hub rings still on.

 

Yup, I've got the VS-XX wheels and Tein CS coilovers. I hope that's the case.

 

It has to be hub centric ring left on the hub. Believe me, there's nothing wrong with the drivetrain of the car. The half-shaft is bolted to the differential and slides through the hub. The hub is firmly mounted to the suspension. The chances of bending a half-shaft is about nill. You can snap them on a rough launch, but they really won't bend. If it was bent, it wouldn't cause the wheel itself to wobble.

 

Pull off the spare and take a look, the hub ring is probably stuck there.

 

I got it towed to America's Tire and awaiting for the replacement tire to arrive. They don't stock 275/35/19's and has to be custom ordered. It's pretty darn costly to replace these tires

 

I know it's been a tough day, but be thankful that you didn't get hurt or were involved in an accident.
