self sealing tubes, winter tires(15 posts)

self sealing tubes, winter tirespessot
Nov 10, 2003 1:06 PM
In the last couple of weeks our weekend club rides have seen
a significant increase in flats. Several of the guys have
suggested Specialized Armadillos for winter training.
I couldn't find any locally and one of the LBSs suggested
self-sealing tubes. These come pre-loaded with slime.
They don't seem much heavier than normal tubes.
Anyone have any opinion on these? Do they work?
Or at $10 a tube are they a waste of money?

Any other good winter tire suggestions?

Slim works but only on tube with removeable valve cores. Pre loaded slime tubes work too. I put Slime in my Tubulars and can typicaly get through the winter without a flat. Last week I pulled out a roofing nail and it sealed!

observe an increase in flats due to the weather. What meteorlogical conditions yield additional road debris?

Am i the odd one here? Blind? Or just lucky?
Me too.... but for me, winter= less miles= less flatsDave Hickey

My mileage drops from 200 miles/wk to 100/wk in the winter. I have less flats because of less miles.
I'll go a little off-topic for this one...biknben

I've found that wet roads lead to greater frequency of flats. Small debris tends to stick to the tire and work itself into the tube. I good rain tends to wash new bebris out into the roads too.

I'll let someone else explain why stuff sticks to the tire when it is wet. I don't know why.

don't know where the original poster lives, but here in central NM we're now coming into Goathead harvest season. My flat percentage greatly increases after the first frost and the little bastards dry out and leave the vine. So bad in some places that I avoid sections of my regular rides until we get some snow to wash the things off the road.
Do a search for "Slime"...biknben

People are doing combinations of many different things to combat fl@ts. Some tire models offer additional layers in the casing (some out of kevlar) to reduce the "F" word. These are not fool-proof. I was still getting fl@ts with Conti Gator-Skins. I just seemed to find bigger pieces of glass. :-)

Tire choice would be the first place to experiment. If the problem continues, then experiment with self-sealing tubes. I would make liners a last resort. Every brands tends to offer a tire for increased puncture resistance.

with all the rain this year, now shouldn't be a time for increasing flats. I'd look for some other reason (maybe rednecks throwing beer bottles).

I don't know where you get your tubes but even Excel (which isn't the cheapest) has Conti tubes for under $5.00. Look around, I've bought them by the dozen on the net for under $3.00/tube.

If you're worried, I wouldn't use the slime, either buy some tire liners or buy tires that have Kevlar BELTS (not just beads). Simple, relativly cheap and will stop anything short of a nail or staple.

I used Michelin Axiel Kevlars in alaska on some of the worst roads I have ever seen with no flats.

Good Luck.

I suspect the entire group ride rode thru a broken bottle.

in my humble experience, tubes preloaded and sold by the Slime people stink. the green goop jams presta valves and they become useless. the sealant does a middling job too.

Specialized Airloks though are an entirely different story. No jammed valves as the sealant is not as viscous as Slime and good puncture resistance. Living where I live (center of the Goathead Universe) I couldn't ride 10 miles without having a flat. Many times, when the tube finally does fail I'll find as many as 10 sealed punctures. I swear by them. $6.99 from your LBS (that sells Specialized stuff) or from their website.

I've had great luck with the Specialized Airlocks! Like Terry I frequently find a number of sealed holes when I finally swap out a tube.

Have you considered Mr Tuffy liners?fracisco

I used them all last winter after a recommendation from a high mileage rider. I did not have a flat after 'installing' them, but the tires were pretty much throw away at the end of the winter from all of the cuts in them. They are $10 a set, and reuseable from season to season.

Id rather have the protection in the tire casing then in the tube. I use the same tubes year round but a durable tire in the winter.

I've had slime completely fail and seal nothing around freezing. Seems others have posted with better luck. The leak wasn't very big either

I've run conti gatorskins and they too won't stop everything.

These are slow hogs of tires but running conti contact tires seem to solve the puncture issue. Plus, with their textured tread, they do well on dirt roads & trails. I'll go for slightly less responsive acceleration to avoid frozen fingers sorting out a flat.

My friends swear by "thornproofs" which are big stupid heavy tubes but I've never actually seen them.

had been commuting on them for 9mo over broken bottle glass, training, centuries etc. Had pulled out of them pieces of glass size of Manhattan ~2500mi, only one unrelated flat.
