These were my first choice but wanted 18" and couldn't wait. They're very nice...gt_sjo said:Just a box pic.. no car yet!

17x7.5 for OEM tyres![]()
I know next to nothing about tyres so this is just a guess: Is this because the high profile tyre can absorb some bumps (as in rough surface micro bumps) and keep more rubber on the road over the rough surfaces?gt_sjo said:I see going to an 18" a backwards step for handling on British roads.
It makes sense when you think about it. I guess one reason to go to 18 inch rims to if you want to fit bigger brakes....gt_sjo said:Yeah, sidewall compliance makes a huge amount of difference to grip. This is why drag racers and F1 cars run decent sidewalls.
Unfortunately the aftermarket see's a touring car and thinks to replicate that setup they need to drop their suspension and run low profile tyres.. It's a completely difference package!
Maybe bigger brakes are needed for the additional grip from bigger/wider tyres... and so it continues.GT86Owner said:I guess one reason to go to 18 inch rims to if you want to fit bigger brakes....
