Schwalbe Marathon Plus 16 x 1.35" (349) SmartGuard 55-95psi tire

The ultimate urban commuting tire. Hard rubber and good durability. Imbeded tread similar to V-monster with higher PSI. Schwalbe claims they're flatproof, and they're pretty much right.

Please note: the Schwalbe Marathon series tires and the Alex DM-18 rim are a very tight fit and are not recommended together.
