BSR 12th Front Tires:

Mounted on High Roller 38 large diameter HR-38 rims, Pro-Cut tires are low profile race tires, and trued to 1.80 front.

High Roller 38 Wheels:
Instead of simply adding a rim filler, BSR has taken the large wheel trend one step farther by increasing the rim diameter to the ROAR and IFMAR legal limit of 38mm. BSRs HR-38 wheel is light weight, with a unique spoke pattern that results from the placement of the strengthening ribs. The internal ribs not only support the outer diameter, but they also add strength to the mounting area, by providing a web of material. Older standard wheel designs leave the area un-braced, resulting in a weak area that could flex. Plus, the front wheel accepts both flanged and un-flanged bearings.
