Run flats

Post by Silverzedtom » Wed Feb 21, 2018 7:10 pm

I’d only ever run four of the same myself. Can’t see there being any real risk in mixing as long as they are matching on each axle. I would be asking myself if I wanted to give up handling in favour of a little cash... seems a shame to stick runflats on a sports car.
