I installed tubes and 32 rim screws per rim and went to the track tonight. The car hooked hard every pass and pulled some rear wheel 60 foots.

Thanks for the update.
I pulled the trigger on a new pair of Phoenix PH337, 31.25 x 12.2 W on 14" wide rims, like I have been running for many years. My current ones are getting old and approaching 200 passes. If the weather gets better, I will be at the track this weekend. I hope to mount, screw, and balance them on Friday. I have always run tubes in mine to stiffen the sidewall and make the tire last longer. 1.24 sixty foot at 3225 lbs.
