The post 2002 Chetak came with Nylogrip tires. Size 3.5x10. With matching size inner tube. The original Nylogrips were universally disdained for their lack of road grip and less universally admired for their durability. Plenty of Nylogrips are still on the road after more than a decade (and more than 20,000+ miles) later.
Most highly recommended replacements: Continental "Zippy," Michelin "S-1", and Michelin "S-83".
Air pressure from the owners guide: 1 rider (18psi front/25 psi rear); 2 riders (18 psi front/36 psi rear)
