I pulled the tire MIPS out of the Cup90 mod to use for my ASA90 1988 Tran-Am Car set because the ASA90 mod has Hoosiers.
To use:
Simply extract the 3 tire mips into your ASA90 Mod main file and your mod will now have the white letter Goodyears. To go back to the Hoosiers just remove the 3 MIPS or place them into a folder for the next time you use them.
Easy-Peasy!
ENJOY!
