Race tire ??? - 01/27/09 05:23 PM
1970 all steel Dart 408/727/3800 stall/4.10s.
3500# with driver, pump gas, street/strip, super stock springs.
Car goes 11.56 at 115 in good air.
I had steel rally wheels with 15x7's on the back. I run the M/T 28x9 ET Drag. The combo liked 15.5 psi in the back on a decent track.
I've switched to Centerlines with a 15x8.5 on the back.
My question is what kind of pressure will the combo like now with the wider rim?
I assume I could run a little higher.
What do you think? How much?
Thanks
Jeff
