Ofna has a set of 1/8 buggy on-road premounts at my LHS that I've had my eye on. They're $27 a pair and have a nice tread design.

They've also got slicks and foams for 1/8. Maybe I'll pick them up today and try them out. Thanks for the heads up on the Sportwerks tires. I've got a set of Badlands copies on my buggy that are a lot harder than the Pro-line Badlands so they should last longer on pavement, plus I picked them up for $20 for a set of 4.....pre-mounted!
