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
