Hi all,

This is my first post. Good to be here. I've been reading the forums for a while and finally decided to join. Got a bmw g30 2019 rwd. Hope someone can help me here.

I've just replaced my original pirelli cinturato p7 run flat tyres for goodyear f1 eagle asymmetric 3 non-rft. All good, but I have vibration at high speed (80mph/130kph). My first thought was improper balancing, but went back to the service and they rebalanced the front wheels in front of my eyes. 0/0. They said the rear wheels are unlikely to cause this, but we'll try to rebalance next week too just in case after the tyres are a bit more broken in. Maybe they were just too busy today... In the meantime I am losing hope though. In some articles I did find that too low or too high pressure could cause this. Tried 2.3/2.3 and 2.5/2.7atm pressures, no difference. Also when the vibration happens I feel it in the floor/seat/steering wheel, read it could be rear tyre imbalance. Also read it could be just faulty tyres, but man am I unlucky if this is the case...

Has someone else experienced this? Were you able to fix it? Any suggestions?

Thank you in advance!

It could definitely be the tires, before diving into that though I would highly recommend getting them road forced.

Thanks maDjzo I'll try to find one in Barcelona. Could it also be because I put 103y xl instead of 99y on the back?

search for it within the general thread. there is one with a lot of pages with good information

If there was no vibration before then get all four wheels balanced. A road force balance is preferable although not essential.

I had to buy new wheels to fix the high speed vibration on mine after aroadforce balance & a standard balance didnt fix it it even though they balanced on the machine ok.

One or more of them must of had a small buckle. New wheels with the same tires finally fixed it.

This post was helpful.
