what to do, i want to switch to non r-flats but the tyre tread are too good to replace. bridgestones on the front and pirelli's on the rear. how much do you think i could sell them for? bit dark at the moment but will measure tread tomorrow 
ok i've taken some photo's and measured the tread. They are as follow Pirelli p zero runflats 255-35-18 90y tread tyre no.1 6mm 7mm 6mm
tread tyre no.2 6mm 6mm 6mm
On blackcircles these are £223.66 delivered or £239.46 fitted. i think they are worth £200 for the pair.
