255/35 gives you 89.25mm sidewalls.samZ4M wrote: ↑Wed Jul 19, 2017 8:29 pmGood to know. But surely the wider would offer more protection, or am I being thick?mr wilks wrote: ↑Wed Jul 19, 2017 7:26 pmsamZ4M wrote: ↑Wed Jul 19, 2017 10:53 amThis thread is a direct result of your pictures, I think it's only fair you pay 20%! Looks lovely. I recall Marc's photos of his, and they are silver, but a bit too much for my liking. Hyper it is...
Looking at tyres, 265/35/19 is bloody expensive (due to Porsche fitment?) is 255/35/19 ok? over £50 each saving!
EDIT: 255 is fine for 9.5J, seems there is a -1.05% (7mm) rolling diameter on them.
Ive run many many 9.5j 19s & always on 255 35 profile simply for the extra meat around the wheel for both protection of alloy & comfort on the road
265/30 gives you 79.5mm sidewalls.
So you're gaining nearly 10mm in sidewall by going for the narrower width tyre.
