I've had my BMW E92 2008 for almost 12 months now, from purchase I've noticed that it likes to chew through the edges of tyres and figured (and was told) that it needed a wheel alignment.
I was unfortunate enough to have hit a roundabout (at about 15mph with the OSF wheel) whilst avoiding an accident with a truck, the result of this was my tracking was totally out and the car wasn't driving straight (steering wheel on the flat would steer the car slightly left).
The repairs were done at the expense of the third party and as part of the repairs I paid for a 4 wheel alignment and fitted new tyres to the front, I spoke with the repair center and they said that the front suspension checked out and all was well. But after 8,000 miles I've noticed that just the front right (OSF) tyre is balding around the edge again, and I'm getting some annoying (maybe unrelated) wobble at 70+ mph.
I've had the car up yesterday on axle stands and had the front tyres off (fitting new rotors and pads) and I've taken a look at the suspension, I cant see anything wrong. There wasn't any give or play on the suspension arms but I've no idea what I'm really looking for. Took the car out after fitting new rotors (the old ones were in a bad state) and it's braking fine but the wobble is still significant and I'm worried that damage has been done to the front suspension or steering. Where is the best place to start looking into this issue? It's due a service and MOT next month so I'm not sure if there going to hit me with a massive bill??
Any help would be appreciated.
UPDATE: Answer to some questions.
- They are low profile 225/40 R18, I do a fair amount of miles 18k per year just on personal to and from work so I should probably be checking the pressures more frequently but I feel I usually keep on top of it (once every 2 weeks)
- I've tried to find my print out of alignment, but I cant find it in with the paperwork I already have. I think I have a copy at the office so I'll check there and update when I can.
- With both of the wheels off, the wear is heaver on the front right tyre (UK right hand drive) than the left but there is definitely wear on both on the outer edge, the inner edge is fine.
- Vibration comes through the wheel, I cant tell if the vibration in the car doesn't feel like it
- It's been wearing tyres un-evenly since I bought the car, the fronts really bald on the edge when I replaced them with about 3.5mm along the other 3/4 breadth of the tyre.
- I do tend to drive the car hard (cant help it, such a nice car to go fast in!)
Current odometer reading is 91,000 miles had a new wheel bearing on the right side at 78,000 miles
