Pissed off.

Recently gave wifey my R32 Skyline with a near- new set of Firehawks on it. Today she was complaining of a 'funny thumping noise coming from under the car'.Had a look, not the wheel bearing as I had feared, but a huge flat spot on the inside left tire.Checked the rest of the tires, no wear, checked the brakes,not pulling unevenly........

How the hell did she do it?

flat spot or heavy spot that has worn off the tread?

She must be getting into drifting on the sly. You know how those beginners are- always locking 'em up due to inexperience!
