info courtesy of KyleEggspuehler21:  This is from a guy we race
with named Charlie. The tires are (Y) rated which is 186+.
Charlie is the most senior racer in the ORR scene. Here are some
answers straight from him:  Here are a few answers to your
questions.  Tires. Michelin Pilot Sport PS2s. Front 275/35ZR18
rear 335/30ZR18 Purchased in Feb '12. Were on their second
(last) year of ORR use. Have been using the PS2s since '07 with
no problems. The first tire failure resulting in an off road
incident in '04 was with Hoosiers.  Although the RPM indication
went to zero when the tire blew, this was due to the electrical
shutoff being tripped which caused the data panel to see no
signal which is zero RPM. The engine did not "lock up" but was
"dead" just as if you had turned the ignition off.  The data
panel continued to function since it is powered by a dedicated
battery.
