My Aeroheat V-rims are 24mm (measurement is outer).

i got a pair and swapped them in today. they're noticeably quicker to accelerate and easier to skid than the 50mm Big Apples i was running, but surprisingly there wasn't much loss of comfort. i'm running them at 80psi.

Update: over 600 miles

After about 500 miles on these tires, I've noticed the back tire starting to take on punctures more frequently....about 3 punctures in the last month....all from glass. Not wanting to have to worry about puncturing out on the road, but at the same time, not giving up these tires that I've grown to like so much, I decided to try the Slime Tube Protector.

The IRC Metro tire is spec'ed iso 406X32, so I purchased the Slime tube protector designed for road bikes (fits 700Cx25-28). The fit was perfect. I merely needed to trim away enough material to allow a 1-inch overlap when installed in the tire.

The added weight wasn't very noticeable. The tire liner, when trimmed to fit the 20 inch tire, feels less than the weight of a 20x1.35-1.50 tube. I couldn't tell any difference in the ride or handling. After the first 2 miles of riding, I actually forgot the liner was even there.

So how well does it work? Have a look at this:

This cut in the tire is the result of me running over half of a broken bottle that had been left standing upright on it's base. While I managed to avoid it with the front wheel, the back wheel rolled right over it with a sizeable thud, accompanied by sounds of glass shards being snapped off the base of the bottle. If you look closely, you can see a light-green glimmer of the Slime tube protector through the gash in the tire. It's been a week now since the incident, and still no air loss, and still no punctures. Not bad for $4.98.

Overall, I think the Metro is an excellent value for the money...and for $10 more, you have yourself a set of tires that are just as indestructible as kevlar tires costing twice as much.

Thanks, James. You are the man. I hate flats. I'll soon be following your lead.

Hmm, can't seem to find these anymore. Too bad.

Do you consider this a benefit? To me, it's a good reason not to get them.

Actually, since I'm talking tires, I'd really appreciate a suggestion for a decent comfort road tire under $18 each. The Metros fit the bill pretty well, but since they're seemingly discontinued I'm now looking for alternatives.

They're for a vintage Royce Union my girlfriend bought this weekend at a yard sale, so tires with white or beige sidewalls would look especially cool. Big Apples would be perfect, but they're pricey and I want to make sure she likes riding the bike before we go big. The IRC Roadlites would look good, but they don't seem comfortable enough.

It surprised me when she brought this bike home; I'd been trying to persuade her to buy a foldy for years and she kept dismissing them outright because she thought the REI Fly-by and Dahon Mu I suggested looked silly. And then she was walking alone by a yard sale and fell in love with this foldy. It really highlights how unpersuasive I was.

All's to say, suggestions are appreciated. Cheers.

Actually, if anybody has a pair of new or lightly used Kwest tires that came with their Swift, I'd buy 'em. (I think they'll fit...)

Cheers,
Ari

Damn, I gave mine back to the shop. Oh well...

thanks anyways!

Power On! cycling still lists them on their site but that might be old info. Could try emailing them.

I have a pair on my Swift that have over 1400 miles on them, mostly on MUPs. Since they don't see much glass or other debris they're wearing very well, even have most of the the mold hairs intact. When they finally do wear out I'm thinking I'll try some Marathons.
