[A4] Inflation Pressures vs handling

[Justin Cady]

I run a decently modified suspension setup with 225/45/17 KDW-2's at 34f 
35r.  Nothing crazy for the street.  The priority is even tire wear.  The 
handling I get on that is pretty nice.  When I autocross I crank the 
pressures up to 40f 42r.  The actual balance does not chance a bit, but what 
it does do is reduce sidewall rollover.  Granted I don't even rub the 
sidewall (the KDW is super stiff), but it definatly helps.

Regards,
Justin
