Tyre choice

[Iansmi1972]

Hi all,

I own a BMW 640D 14 plate and need to change my tyres. Currently it has Dunlop sport run flats and they aren't the greatest for grip and ride

Recently had it remapped and loving the extra bop and torque but no idea on best tyre, perelli, Michelin?
Can anyone advise or recommend either a good run flat or do I change to normal? The rims are 20's

Many thanks

Had Pirelli P Zero, Bridgestone RE050/S001 and Goodyear Eagle F1 RFTs and would rank them F1=P Zero>S001>RE050.

I have an F30 335d xdrive. It has Pirelli Pzeros in 225/40x19 front and 255/35x19 rears. The grip is good. I am just reaching 24k miles and have 3.5mm left on front and 4.5mm left on rears. I like the tyres, but may go down to 18”, and I don’t think these tyres are available for 18”. The 19s are OK around here, but in some pot-holed counties, 18” would be better.
