Not sure if there is such a thing. Sort of a cross between a motorcycle tire and a formula v tire. Something for high mpg on a super light car. Or would a cycle tire work?

I'm building an Austin Seven Ulster replica (Sprite powered) and it has skinny ~Nankang 135-15 Tires~ (they look thinner than the picture)

Is that the sort of tire you're looking for?

Coker tire is making some V rated ( or higher ) for vintage racers, check 'em out

Just fishing for ideas but I'm thinking of a vehicle somewhere in between these two. Very light with low rolling resistance.

Those are tall and skinny tires right there.

your tire is also your brakes , if you do not have enough tire on the ground the momentum will just push you , full brakes on or not

Good point. But four tires stopping a car that weighs the same as a medium sized motorcycle and having a larger total contact patch should be quite sufficient.

I'm sure the VW's tires are one off. The Naking's that aeronca65t suggested aren't too bad, maybe a bit too heavy. Any other suggestions? Would motorcycle tires be a bad choice? The fact that they are rounded. Will there sidewalls handle car stresses? Each tire would have to handle 200 lbs static.

Haven't responded for a while, been checking out alternatives. The Nankings seem to be pretty light and narrow for a car tire, just wish there was a lighter one.

V This is sort of what I'm thinking, but with a lower chassis and maybe a 20-40 hp combustion engine if there is one light enough. Not sure if a combustion drivetrain can be as light as a small electric set up. http://www.youtube.com/watch?v=gFDi6ksvON4

This pretty neat, too: http://bugev.net/BugE_in_Media.html

You could look into sidecar tires too. Motorcycle sizes and weights, but with a mostly flat contact patch.

That Michelin looks sort of like a modern space-saver spare.

Hey, that's a creative idea! They come in 18 and 19" with 3 1/2-4" widths. Certainly a good size. I'll look into them. Motorcycle sidecar tire

Pretty cool researching these tires. Didn't know that Royal Enfield and Ural motorcycles are still being manufactured!

Gravity racers use 20" bicycle tires
