My 2007 E91 320D Touring M Sport has the factory spec Runflat Potenzas RE050AI but the Load ratings don't match on the front axle and the car is a bit twitchy.
This may just be a feature of RFT as others have mentioned but I would like to try the factory spec.
Would you please be able to tell me what the original spec for the tyres (incl. Load and Speed) is as I can't find it anywhere (no access to KSD).
Being an M Sport it is staggered Front 225/40/18, Rear 255/35/18. VIN is K100318.
I believe the front was 88W and Rear 90W but would like this confirmed.
(Please don't price the tyres for me just now as I have a heart condition)
