Tires

The spec tire is the Nankang AR-1 Semi Slick. Depending on track surface you should get 4-6 competitive days from a set. Owners have seen as many as 35 heat cycles from this tire before serious degradation, depending on alignment. Many compare it to a Hoosier on its 3rd heat cycle, which is incredible performance and longevity for the cost!

Tires can be ordered directly from RAW or from your dealer. The sizes are:

• 185/60R13 Front
• 205/60R13 Rear

Tire Pressures

Starting pressures vary by ambient temperature and driving style. These are community-tested starting points:

Nankang AR-1 (spec tire):

• Cold: 18–20 psi front, 18–20 psi rear
• Target hot: 26–28 psi front and rear
• Adjust cold pressure to hit target hot pressure at your track

Hoosier R7 (alternate):

• Maximum hot pressure: 24 psi
• Cold starting point: 17 psi has worked well for many drivers

Hankook slicks:

• Treat similarly to Hoosier. A growing number of owners prefer these over Hoosiers at lower cost.

Monitor tire temps across the surface (inside / middle / outside) to diagnose alignment and pressure issues.
