3 Series xdrive
Ok, had my 182 a year now(10,000 miles), had to replace one tyre on the front due to side wall punture(wheels are unkerbed and always avoide pot holes etc..)
I check my tyre pressures every week, and they are always require air put in them, this week they were really bad:
20 PSI, 24PSI
7 PSI, 29PSI
I have never known of tyres to lose so much pressure so quickly
