Reasonable priced R slick - the Proxes 235/35/19 is 20mm shorter than 265/35. So with 235/35 I can lower the car further by 10mm.
How fast would it be lowered by 10mm?
So rubber calculation.
Assume Proxes RR has 230mm rubber on the road (235 minis two grooves)
Width - rain grooves
The 285/30 GY Asym 3 has 221mm rubber on the road
The 285/30 Corsa has 231mm
The 265/36 Cup2 has 239
And the winner from the max performance is the 285/30/19 Ecsta PS91. due to 4 narrow groves it has 250mm rubber on the road. The PS91 was also the fastest road tires with best lap time at NYST.
The king is still the Hoosier 265/35 for most rubber on the road and I am sure the rubber compound.
Obviously there is a lot more to it, and I counted only the longitude grooves, not the latitude ones.

I'm confused. You're suggesting max rubber contract patch (less rain grooves) = greatest tire? And what fires lowering the car an additional 10mm do? |
I honestly don't have answers. I am just reporting my observations and wonder out loud.
More rubber on the road in the dry seems to correlate to speed.
