I am in need of new autox tires and the offerings have changed a bit since I last bought a set.

I am curious as to what people are running?, what do you like? is there a good trade off cost/performance?

I will be mounting them on 15x6 cookie cutters

Aaron’s car is no feather weight. Around 2200lb with driver.

A tire engineer once told me 1psi per 100lbs is a good starting point and we have found that to be true. Aaron’s car is still a little camber limited so we usually run right around 23-24psi hot to try and keep the shoulder alive.

Here’s what 24psi in a 1.3g corner looks like. Pretty good stretch for a 205 on a 7in wheel.
