Typically Goodyear would about a 1000 lefts and 1000 rights to Martinsville. You can see they have upped that number by around 40% anticipating significant tire wear. Many teams will also begin with pressures lower than even the low minimums recommended.
GOODYEAR TIRE NOTES FOR MARTINSVILLE October 18-20, 2002
Number of Tires Required:
Left - 1390 Right - 1420
Tire Circumference:
Left - 86.2" Right - 87.4"
Technical Inspection Inflation:
Left Front - 15 psi Right Front - 25 psi Left Rear - 15 psi Right Rear - 25 psi.
Minimum Required Inflation: Left Front - 11 psi Right Front - 22 psi Left Rear - 11 psi Right Rear - 21 psi
Estimated Pit Window: Every 150-160 laps, based on fuel mileage.
Notes: The combination of left-side (D-5692) and right-side (D-5704) to be run this weekend at Martinsville is Goodyear's true short track set-up in its 2002 tire line . . . Martinsville is the only NASCAR Winston Cup track where this left-right combination is used, though it is also used by the Craftsman Truck Series at South Boston, as well . . . this is the same tire combination that Goodyear brought to this track for the Winston Cup/Craftsman Truck Series weekend this past April . . . another unique feature of this combination is that the right-side tire is used in all four tire positions at both Winston Cup road course events.
Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Racing: "The main tire issue every time we come to Martinsville -- which has relatively long straightaways and tight corners -- is caused by heavy braking, which results in excessive brake heat. In extreme cases this can lead to the bead on the tire melting and result in a loss of air. However, we have configured the components of these tires to protect from this happening as much as possible and we have effectively limited this problem over our last several trips to Martinsville.
"Another concern for teams this weekend is that the surface of the track has recently been ground down to make it smoother. Based on a recent Winston Cup test session at Martinsville, teams should anticipate higher wear than what we've seen in recent memory at the track."
