I have been asked about the weight of the 185/70R15 CN36 tyres. just so i had some comparisons i weighed the alternative tyres we had on our shelf

Pirelli https://www.longstonetyres.co.uk/tyr...o-cn36-n5.html the proper Porsche tyre that has the N homologation 8.kg

Michelin https://www.longstonetyres.co.uk/tyr...helin-xwx.html 9.6kg

Avon CR6ZZ https://www.longstonetyres.co.uk/tyr...von-cr6zz.html 10.15kg

Interesting when you consider how much money is spent cutting down the weight of Sports cars. Of course by far the most important area is unsprung rotating mass. And then involved in that, the further away from the central axis the weight is the more the issue. so tyres are critcal

I did weigh a few tyres, there was a bit of scope in the weight, and the Michelin was impressively the most consistent.
