I posted this in the tire section but I figure I'll add it here since it's higher traffic. Went out for a drive last weekend this occurred at a transition between highway asphalt and bridge concrete at around 80 mph. Felt like I hit a curb but afterwards the car felt just fine. Only the front tire made a thud. The back was quiet, which is a little confusing. There was definitely no pothole there. There was zero indication that anything was wrong.

After the hit I spent another few miles on the highway between 80 and 110 and then on the curvy roads for the remaining 8 or so miles home I was pushing it hard and enjoying the lateral g's.

I about shit when I got it into the garage and saw this:



BMW is not far away but the PSS on Tire Rack are $560 to my door and the dealer wants $150 to install!

Discount tire has them and will have them installed for $612 out the door. So it goes there on Friday. Problem: it's 15 miles away.

Normally I would never drive on such a tire but I already did. Hard. So I figure I can baby it down a long smooth feeder road. Probably not the best idea. Hope I get lucky.

That's the left front PS2 with 11k miles on it. It was fine before. What I don't know is if it looked just like that after the hit or did it worsen with the subsequent 10 miles of driving. How the thing held together is beyond me.

Worst case it blows at 40 mph and I call roadside.

If it was summer I'd probably put the car on stands and pull the wheels. But it's friggin cold out there!!

Worst case it blows at 40 mph and you fall off the roadside.
Just take the entire wheel off and drive it in another car to the tire shop.

The rear probably felt like half the impact because the mass of the whole car slammed the front rim into that pothole whereas the mass of only the trailing end had to be bumped up onto the higher section of road. Plus rear tires are wider to dissipate that impact. That's my guess on why the front got damaged so much worse. Also, thank god we don't have run flats. If you did, you'd have a bubbled and compromised tire in addition to a crack in your rim that probably would be so bad that it wouldn't hold air. And if you had forged rims the lip would probably have been bent. Good guy tire, taking most of the damage.
(also get an alignment) There is no way your front stayed in line after that hit.

Your life is worth a lot more than the cold...I hope.

Man up, take it off and use another car to take it to the tire shop! Try having these situations where I currently live, -20 Fahrenheit on a daily basis.

It takes no time to jack car up and take 1 wheel off. I wouldn't chance it. Not to mention if the tires pop, it could do cosmetic damage (maybe?) yet alone driving off the road.

My wife is from Calgary. I went there for Christmas once. Once. We live in the South for a reason.

Was going to jack it up and pull the wheels tonight. My floor jack doesn't fit under my car! Never had that problem before.

I'll sleep on it and look at it in the morning with less tired eyes.

What a pain in the ass.

Mustang:
Place jack under car at any number of points.
Lift and place jack stands at jack point, subframe connectors, control arms, etc.
Remove nuts and wheels.

M3:
Try to place jack under front of car. Huh, too low.
Jack up rear high enough to get jack stand under front jack point.
Move jack to front jack point and raise to get other front jack stand underneath the car at the specified jack point.
Remove bolts.
Try to remove wheel. Huh, seized to hub.
Put bolts back in loosely.
Whack the shit out of back of wheel with hammer and 2x4.
Remove wheel.

Seriously, that was a lot more of a pain in the ass than it needs to be. Too much plastic and breakable stuff underneath these cars.
