I currently have access to tires from several manufacturers. 
I usually carry in-stock:
   Kenda Millville Sticky
   Michelin S-12 XC
   Select Michelin MS3
   Select Michelin Starcross mini tires
   MotoZ Tires ie, Terrapactor S/T, Enduro S/T, Enduro I/T
I can order Bridgestone, Dunlop, Rinaldi, Deestone, and some others.  I'm working on a source to order Pirelli tires. 
I also carry heavy duty and ultra heavy duty tubes, rim locks, and many other wheel accessories.
