HiRes - Michelin Pilot Sport Tires for Custom Wheels
I made them for myself and you can use them too if you want.
This should work for any NFS that uses this method of tire texture replacement and supports HD content/Custom wheels, however I have only used them in Underground 2
There are 2 to choose from, one with text that pops in game and one that's plain jane.
Requires "NFS-TexEd 1.7" and "HD Content support" links in readme file.
Cheers.
