BMW * / Mercedes MO tyre rating

[Beta]

I need to get some new tyres for my wife's f07 5 series GT and will need to keep the run flats.

Are those with the BMW * rating any different to MO rated or unrated tyres? As they all seem to have the same load rating, I can't imagine there is much if any difference in spec but there certainly can be in price.

Any thoughts?

Often the OEM specific tyres are such to control the tyre size rather than generic ETRTO envelope and resulting balloon tyres from XYZTyres.Ltd that could possibly be fitted.

This allows companies to meet legal tyre coverage AND good tight coverage of the tyre with the bodywork for aesthetics. Its a nightmare trying to do some of the standard tyres otherwise you end up needing bodywork to cover the big daft tyres and then the ones the OEM fit with the wheels to meet ride and handling can look lost and you lose showroom appeal. The unique specs can have subtle differences to tread and compounds aswell.

German premium marques are happy to tool the unique tyres to avoid this compromise. So basically aslong as you stick with the decent brands you should be fine as they vary very little.

Thanks both, there's not a massive choice in these sizes anyway with them bring runflats, basically 1 or 2 choices from the premium brands.

I was specifically asking about the pirelli pzero */MO / standard which sounds like there should be very little in it.
