Schumacher Shimizu F1 V2 Front Pre-Mounted Rubber Carpet Tires (2) (Soft)

These tires are great for carpet racing only (The 571C). They are broken in in 2 runs of 5 minutes and you'll want to make sure you glue the side walls of the tires about 3mm from the top towards the middle of the rim. For front tires, you will only want to use thin glue, apply with aid of 3-10mm curves tape and use a steel tip tool or glue bottle with small tip nozzle. For green tracks/low grip carpet, you'll want to have no glue on the contact patch. For medium/high grip carpet, you'll want to glue the outer contact patch just 1mm and keep an eye on it after every run to reglue as needed. For the ultra high grip carpet, you'll want to glue the outer contact patch 3mm only if you are traction rolling. Overall, these are a great carpet tire and you should easily get multiple runs on it. Note that these tires do not work well for asphalt

Tires worked great on CRC black carpet. CA applied to visible molded-in shoulder line and extended inward 3-4mm smaller diamter than the shoulder line. Tires broke-in in 2-3 runs.
