I've too have runflats on my
MC, it's my first experience of runflats so am no expert.
what I did notice is that on previous cars I always checked the tyre pressures once a week and never really seen any significant change.
on the
MC for some reason I thought as it has the pressure monitor I did not need to check them as regular........................................... ...mistake
yesterday I checked them to find they were all 24psi and I like to run at 30psi
I have 17" flame alloys and they must lose pressure more than normal tyres.
based on this your tyre dealer could be correct as the wheel must play a part in retaing the pressure ?
why not swop the tyres around so that you have a different tyre on the suspect wheel to prove if it's the wheel at fault ?
I will now check my pressures on a more regulau basis, what pressure do you run at ?
