while driving a
BMW X1 X Drive
(225/45 R18) on
a combination of roads
For my 2011 BMW X1 E84 X-Drive I bought a new set of 4 of these run-flat tyres. The fronts are 225/45/18, the rears 255/40/18.
In the 2 years of use I can say they are an excellent, but not exceptional, tyre. My driving is a mix of inner city urban, open road highway and rough unsealed gravel roads. They perform fine in the city, nothing really negative to report here. On the open road/highway I find them noisier than I'd hoped and the ride is firm and at times unforgiving over bumps, so much so that at speed I have to have two hands on the wheel so as not to be thrown off-track! This is probably my biggest criticism of what I assume is the characteristic hard and lumpy ride of these run-flats. On the positive side, they handle in and out of corners at speed well.
I'm considering changing to non run-flats, probably Michelin Pilot Sport 4 front and rear as a well-reviewed, quieter and more comfortable alternative.
