Hey everyone,

We are catching some cool weather here in Houston so I will be heading to the track tomorrow night. I have some 26x11.50-17 MT ET Streets from my last Mustang on 17x9 bullets. Since these tires aren't sold any more, I can't find much info on what my starting pressures should be. I can adjust down depending on what the track will hold.

Bone stock 2019 GT A10 400a with drag mode and 3.55 gear. I was thinking of starting pressure of 18psi cold. I don't want to start too low and bog as I can only launch at 2000 rpm.

Previously on the PP1 wheels/tires I have, I only managed a 2.0 60', 12.2 @ 117.79 spinning off the line, spinning and hopping 1-2, and spinning 2-3 shifts. Selector in D, adv track off, and drag mode. IAT at time of that run was over 140*.

Well, in case anyone is interested, with a mostly stock setup, car hooked at 18 psi cold on the 26" bias ply tires ok - 1.85 60'. Cut same 60' at 16 psi cold.
