Tire Pressures for Star Specs

[NigelStu]

Based out of Detroit, team members in central WI, a bit outside of Chicago and Boston.

We will be at the Road America event at the end of the month. Pending having a working car, we will also be at Michigan International in August and most likely the Road America event in Oct (or maybe, maybe we will will go back to Nelson's Ledges for the 25 hour...) I had considered Brainerd but that is one heck of a tow for me.


Yes, 30 psi COLD would be a good starting point.

You can also add or subtract pressure dependent on when the tire rolls over on it's side during cornering. If the scuffs are over the edge, add more air. This is why teams use markers on the edge of the tires. However I've never run chump or lemons and this advice comes from auto crossing.
Some tires have very stiff sidewalls like the Star Spec and you can get away with lower pressures typically in this case.
