Snake Bite Flats(9 posts)

Snake Bite Flatsjrm
Jan 29, 2003 8:10 AM
Hey all,

I was using 28c bulletproof Panaracer Tserv's and switched to 23c Axial Carbons for better mileage and rolling resistance, I have um @ 120psi and their mounted on on OP's on my CX bike. I commute in a area that has RR tracks, rough pavement, street debrie and lots of uneven surfaces.

yesterday i jumped some RR tracks and got a snake bite flat. Is there a limit to riding 23c tires? and what is that limit.

23s are just too small for that kind of riding. I don't even think about anything smaller than 28s anymore, and I do most of my commuting on 35s (I weigh 225, so you can probably use something smaller). You don't mention what kind of bike you have, but if it's a typical one, you're probably limited to 28s or some brands of 32s. You'll be able to lower the tire pressure for a better ride, too.

I run Axial Pros 23s @ 100 psi for road riding, but for my commuter I have Specialized Nimbus EX 700 x 28 and run 'em @ 80-90 psi, no snakebites ever. I weigh 195.
Increase volume (tire size) or pressure...biknben

Since your tire pressure seems to be fine you have to either increase tire size or ride more gingerly.

the occasional flat is par for the coursevelocity

Given your terrain, if you want bulletproof, you may need to return to larger tires with lower psi. I've been using Michelin Axial Bi-Sport 23s on my beater. Recommended max psi on these is 110. Given my urban commuting, I face awful road surfaces with large potholes, debris, wayward cars, jumpy peds, maniacal food deliverers on bikes, etc., and the occasional flat. I see it as a par for the course and always have spare tubes and such on hand.

Just this morning I said to myself that I've been on an unusually long flatless streak, which, of course, means I'll have a flat tonight when I go to the garage to retrieve my steed. I'm soon going to need to replace the Bi-Sports and may try something else next but am fairly happy with these all-around tires. I like having 23s on my commuter because I also use it as a back up trainer and bad weather bike. Many swear by Contis Gatorskins. May try them next.

I found that most guys had snake-bite flats by installing a tube that was 'too big' for their tire (i.e., using a tube rated much wider than their tyre)All that extra rubber just doesn't seat wellunless you take care to properly install it...FWIW,once I get the tyre back onto the rim, and before I fully inflate the tube, I press the valve-stem/tube up into the tyre (while holding the tire in-place against the rim), and then lower the valve-stem back against the rim...then I thoughts are that I've eliminated any tube-pinch at the stem area.....I don't know if it works, or if I've just been lucky, but I haven't had a pinch flat since I started doing it...(KNOCK ON WOOD !!!!!)
GUESS what my next flat will be :)) Open mouth, change flat!
Won't hurt to give it a go.
I bunny hop twice daily on 23c Vredestein Fortezza 145 psiteamsloppy

I commute to work almost daily by bike (weather and cleint visits excepted) requiring a bunny hop over a bridge joint, sometimes two bridge joints (one is worse than the other) usually one going to work and second time coming home, sometimes twice going, and twice coming home. I had less than 16 flats in 4500 miles (my log is at the office and I'm not). I think that is about about 2 x 34 x 5 = 340 bunny hops on this set of tires. Never a pinch flat.

I am using a Vredestein Fortezza on the rear and a Fortezza TriComp on front both 23c. I run 135/140 psi. I weigh 196.
