M235i steering wheel vibration

[george123]

hi, recently bought 2014 M235i from a dealer , not a BMW one. Wheel vibrates at 70-80mph so guessed tracking needed doing but hasn't made any difference, tyre guy said only 1 front was out. . It does have 2x Goodyear 4 Seasons (these are essentially a winter tyre?) on the front and a pair of Dunlops on the back.

I guess the dealer stuck these 4 on to get it through the MOT. Could this mix and match be the cause? Tyre guy suggested this could be the issue if the tracking didn't resolve it, which it hasn't . I was planning to put decent 4 matching Michelins tyres on it , but was hoping to avoid the expense for a couple more months.

Before I spend £500 on new tyres, could the vibration be caused by something else ? Something with the suspension maybe? Anyone similar experience with a M235? Thanks

Had something simillar on an e92 a while back and it was a sticking caliper on one of the back wheels, only done it on certain roads and the cause was a twisted brake hose.
Also had it on my berlingo van on the front wheel on a 2 month old tyre.
Puncture repair was repaired with a plug, second time this happened with the van and repaired with a plug and both times had wheel vibration, took it to a proper tyre guy and he removed the plug and used a vulcanizer to repair it, no more vibration.

Thanks. Pretty sure it isn’t a sticking calliper as there’s no issues when braking.

Did they check that the wheels are balanced when they checked the tracking?

As above, sounds like balance to me. Without stating the bleedin obvious, we have an m235i and no way you should be getting vibrations.

yes did both. he said the balance was only out on 1 front. I wonder if the mismatched tyres put on my the dealer have flat spot on the front?

would this be visible if I jacked it up?
