[Supras] Tire recomendation

[berniek at technicaldevelop.com]

Jeff:

    Thanks for the response.  I should have stated that the tires on the 
car are RE750's.  Interestingly the RE750's are not rated that much 
differently than the RE050A's:


RE050A:  Cornering:  9.1. Dry traction: 9.2.  Steering response: 9.1.
RE750:     Cornering: 8.6.  Dry traction: 8.9. Steering response: 8.7.


    Maybe the ratings are not really indicative of how the tires feel 
and behave in practice.  Tonight before writing, I took my favorite 
drive in the coldest weather we have had here in the Northeast (maybe 
28F to 30F earlier tonight).  In September weather when I first got the 
car running with the refreshed engine it was not that much different, 
though, although WOT bursts were kept to a minimum until I had about 400 
miles on the engine (just about now). 


Any ideas about the influence of temperature would be appreciated.


    Bernie
