TR-4, 205-55/16's - I run 26 psi cold front, 24 psi cold rear. Will be 
mid 30's hot.  More than about 26 cold and they start to get skatey.  If 
I run more rear pressure I get understeer, but moving the rear up or 
down by a PSI makes a significant difference.  With IRS you'll likely 
have them closer to each other in pressure.
Love those tires.  Switched to them when Yokohama stopped making the 
205-60/15 A048's.
Cheers, Tony Drews

      I run 205-60/13s on the GT6.  I called Toyo tech a while back, and
      they told me the tires like to run at about 35-36 pounds hot (this
      was the R888s - I assume the Rs are similar, which is what I run
      now).  Iâ??ve found that the tires will gain 6-7 pounds from cold to
