[Fot] Speedster Tire Follow-up and Road America

[Bill Babcock]

As to the question, I've never found a tire that didn't have  
increasing amounts of understeer as they heat up, but an extreme  
amount is a good indication that your tire pressure is too high. Once  
again I'll tell you the only way to get a good tire pressure is a  
skid pad and a pyrometer, but I'm running 17 cold on Peyote which is  
1550 pounds. I pushed it up a little to 18.5 last weekend at Road  
America because I thought I might get more speed in the straights,  
and there's lots of straights at RA. I did indeed see higher temps in  
the middle and a little more understeer. I outfoxed myself and stuck  
my Hoosier DOT Radials on to try to beat the local hot shoe (Dave  
Jahamiac (spelling)) but lost a little more than a second because of  
the increased friction. Got to pay attention to the nature of the  
track. going fast on a track with long straights is all about top  
speed and corner exit, not maximum mid corner speed.

I feel a little stupid.

Still, I had a great time, learned the track well enough to touch  
2.44.something (on Speedsters), beat the frickin' Porsches and Loti  
in group four, finished first Triumph in Motrah and won my new  
favorite watch. THANKS JOE--I really like it. I have a few watches  
and never wear them but I've been wearing this one ever since I left  
the track.

I'll do a writeup on the blog as soon as I have time. I need to get  
to VIR ASAP. Peyote has a vibration at high speed that I don't like  
(perhaps a driveshaft headed south) and a tire carcass got kicked  
into my trailer at high speed today and it screwed up my waste water  
drain lines. Got some wrenching to do before I catch a plane on  
Thursday.
