upgrading to wider tyres?

[Black miata]

I have just fitted 215 45 x 17 tyres to my NC and can give you the following information.

Speedo error is negligible.

Road Ride Comfort is sensational

Track work disappointing at normal pressures.

I have been experimenting and have found that 36 all roand still gives a nice ride and good handling but for the track I have been running at 40 psi. I am still experimenting with pressures and will post more infor as it comes to hand.

They are a premium Goodyear product, and perform brilliantly.
