![]() But, yeah! Actual tire metrics would be interesting, and I agree the 3.07s were available, perhaps more so than what would be exactly perfect for the "task at hand". Any way ya slice it, the RR was a fascinating moment in automotive history, regardless. ![]()

Since 1990, I've written several articles on the Record Run for different magazines and web sites.
The tires size was not in the last two stories I did, but a search of pre-2000 manuscripts and, finally, found it. The tires were special race radial race tires done by Goodyear just for that program and the size was 25.5x12.0-17. That tire was used at all four corners on both cars. |

(small)progress update..my fsm's have arrived, i've done a bit of reading there and here..have opened the first connection in the pump suction line (which is just a coupling..why is it there, iwonder..) and with it thumbed off the pump stops instantly, telling me there is a leak downstream which is under the plenum unless its map hose ..so i'm starting to think i'm gotta remove the plenum..
symptomatically :key on engine off pump runs forever..there are times when i punch it and really feel a power surge at 3000 rpm or so, and there are times when i dont..also there are times when i punch it and i think the secondaries are open, and then it peters out and wont get over 5500 rpm so i guess the secondaries have gone closed as vac drops and pump cant keep up..
