Prevent Flats??(15 posts)

Prevent Flats??ST
Oct 28, 2002 2:35 PM
In the last 4 weeks, I had six flats. The area where I bike usually has alot of broken glass and debris. Does any of you use lizard skin kevlar product to prevent flat? Does it really work? Or do you use anything else in that matter?

- many people seem very satisfied with the continental gatorskin tires.

- another possibility is to use thorn resistant tubes. But they are heavy.

- you can also use a tire liner. Is that what you are referring to with the "lizard skin kevlar" ? Isn't this expensive and light stuff ? I personally use something that looks like plastic. Don't know if it works, it's not too heavy and I got it inside the tire when I bought a second-hand bike, I keep using it. I just had a flat after about 2000 miles flat-free.

I'm sure people's results vary, but I put on a pair of Gatorskins a couple weeks ago. So far both tires have flatted due to small glass chips. For me, they were a waste of money.

This does not sound normal. Have you tried replacing the rim strip with Velox? If not, that would be a good place to start.

Specialized Armadillo tires are really durable. I rode them last winter and found no cuts on the tires. The downside is that this tire is heavy and a pain in the a** to mount.

Chunky's 100% right. But the upside is NO flats, 3 winters with over 12,000 miles w/o a flat, over all types of crap in the road. Who wants to change a tire when its 35F? Don't corner hard the first 100 miles though, let 'em soften a little. I'll probably get a flat tomorrow now...

Double ditto on the Armadillos. Run the 700x28s on my winter beater. Definitely bomber and it ups the weight on my rig to north of 30lbs. But it is nice to plow through all the crap (snow, ice, crud, salt etc.) with nary a care. And they look oh-so-chic with fenders, waterbottle cozy.

What is causing your flats? Small shards of glass or bits of wire are pretty tough to beat, and you might consider finding some tire savers. Solutions like Mr. Tuffy often start causing flats as the liner rubs agains the tube. Tires like the Specialized Armadillo and thorn proof tubes do work, but the ride is not the greatest. Start with the cause of the flats, and then determine your course of action. Plenty of people have reported "flat prone tires/tubes" only to discover a bur on their rim, poor rim tape, or a bit of glass in the tire that they didn't remove.

Thanks for all of your replies. I checked the rim, the tape, and the tires themselves. They look fine. The tires are the Continental GP3000 so they are a little bit on the light side. But I like the traction and the supple feel as compared to other tires. I put about 1500-2000 miles per year and I change them every year. I think I going to get some new rim tape to see if it solves the problem.

Since noone else has mentioned them yet, my vote for flat prevention is Mr.Tuffy's. Take it from a former messenger, they WORK. I rode for weeks with nasty tears in my tires, but no flats. They aren't the lightest but they last forever. Anyway, if you're just commuting or training, why worry about a couple of grams when you can ride worry-free.

Screw all that heavy crap. If I wanted big burly tires I would have bought a beach cruiser. Deal with flats, I use glueless patches if I have 2 extra minutes to put one on..If I don't, then I throw in the spare..You carry a spare, right? Carry a good pump too. I use the Topeak Mtn. Morph and it rules. 90 pumps gets you 100lbs. If I'm in a rush I can change a flat in less the 5 minutes. Makes no sense to spend big bucks on these machines then to insult them with tractor tires....But I would recommend inspecting tires after rides or maybe at a half way point..There are times when a foreign object has not yet punctured the tire, but is hanging on and waiting..Check rim tape and make sure tires are properly inflated...good luck and don't let a flat spoil your ride...

No problems with them causing flats, either. While it can be difficult in urban settings, another option is not to run over $hit on the road. Paying attention to where you're riding sounds kind of obvious, but when I rode regularly on group rides some of the guys who flatted more often were also guys who were careless about their fellow riders.

I use them on all my bikes. Make sure you use the orange liners for road bikes

I use a cross bike in the winter, and it helps with traction too. But I live in a rural/suburban area and glass is not too much of a problem. I find the extra resistance is a help for training, and you are going to go slower in the winter anyway.

They are heavier than kevlar but way cheaper in cost. I've been riding them for two years and have not had a flat since. Best $5 I ever spent!
