To Patch or Not to Patch....(12 posts)

To Patch or Not to Patch....callthedoctor

Noob here....I'm sure this topic has been posted before, but I hear conflicting recommendations about patching tubes or replacing them....

Running 100psi or greater in tires seems logical that they should be replaced (does pressure matter, IOW will high pressure blow patches?)....but wouldn't it be a rather subjective based on size of puncture, time issues, ect.

Does it matter?

Also, as far as puncture resistance, is it better to go with thorn-resistant tires, slime tubes, or spin skins? Do these things slow you down to a noticable degree or is the added protection worth it?


p.s. I'm a 240lb clydesdale who competes only against myself.

higher pressure will not blow patches - and most people do patch. Just make sure you get the patch to stick well (clean, rough things up, etc). In theory the patched area will be stronger than the rest of the tube.

I replace the tube on the road with a new one and repair the punctured tube when I get home and use them for spares. It's just easier to replace the tube on the road then to mess with locating the puncture and repairing it with glue and a patch. No worry about blowing patches, just make sure the patch sticks the first time around...
Yes, patch it, but...Alexx

I agree with replacing the tube on the road and then patching the tube at home.It's much easier and quicker doing it at home than on the side of a road.

If you are 240 lbs. I doubt the extra weight of the spin skins or slime would really cause a big difference in your overall speed.I don't have experience with these products so I can't give you an opinion on their effectiveness.Possibly another reply could help you there.

Try Continental Ultra Gatorskin tires. Made of Kevlar, practically unpenetrable. I don't use special slime tubes or anything, b/c I don't have to. They don't slow me down any, in fact they feel better than my previous stock Hutchinson Carbon Comps.

I have Conti GP now and love them.Is the ride comparable?
How well do they wear?
Mr Tuffy is an optionPdxMark

Another tire liner product. I've been using it this summer, both on a commuter and my road bike, and I LOVE the absence of flats. It's heavier than some liners (spin skins?), but is non-adhesive, so it can be re-used as you wear out tires. What I like about a liner over a bomb-proof tire like gatorskins is that I can get the benefit of a nice-riding tire plus puncture resistance. Some bomb-proof tires are reputed to have rather harsh rides.

I don't race so the extra weight with a liner is not an issue for me.

I buy tubes on sale at Performance for $2/tube every year. Sometimes I get the Michelin ones for $3/tube. A patch kit costs $1 and once you use it, its pretty much gone. The glue dries up after its opened rendering the patch kit worthless. For an extra dollar or two, I just replace the tube and pitch the old one. I suppose it may make sense to take the punctured tubes home and patch several at one time.

Glueless patches ... forget it. I carry them as a last resort, get me home measure, but they don't work very long.

Is this for a mtn bike, or are there really thorns on the roads where you ride? I tried Mr. Tuffy's once and wasn't impressed. I hear slime works well. Frankly, I think the best approach is to buy a good tire. Try some Michelin Axial Carbons. Maybe Specialized Armadillos (I've never tried these, but know some folks who like them).

i use park glueless patches and have never had a problem with them. they dont leak and last a long time. i have used other brands that suck and start leaking even before i finish my ride. patch your tires and use park glueless patches.
What are you trying to accomplish?Spoke Wrench

I think that if a product is properly designed for its purpose, you shouldn't have to buy a lot of additional add-on products to make it fork satisfactorily. Consequently, I'm not a big fan of slime inner tubes, Spin Skins and Mr. Tuffy's for road bikes. In fact, I've heard reports from several diverse sources of Mr. Tuffys abrading the inner tube where they overlap and actually causing flats.

Back when I used to get more frequent flats, I always patched my old inner tubes. I'd save the leaky tubes in a box and do a bunch at a time while watching the football game. Lately I've only been averaging a couple of flats a year so I generally just pitch 'em.

I only have one bike today that has averagely fragile tires (Michelin Axial Pros). I generally only ride it on country roads that have very little broken glass and we in St. Louis aren't plagued with goat heads. My other road bikes have Specialized Armadillo tires. These leave something to be desired from a performance and ride standpoint, but they are all-but bulletproof. If I were buying a new set of tires today, I think I'd try a pair of Conty Gatorskins. I think they might be a good balance between performance and puncture resistance.

I'm am pretty much a compendium of the earlier answers:

-I always use new tubes as replacements on the road.

-I save up old tubes and patch them in bulk as replacements for the rare occasion that I find a tire flat when I am at home. I never patch a tube when the puncture is on the seam - too much likelihood of a slow leak.

-I live at the center of the Goathead Universe, so I use tubes with sealant - Specialized Airlok, not the "slime" brand. In my experience (tried one, never again) the slime in slime tubes messes sorely with presta valves as in clogging them. The Specialized tubes use a much less viscous liquid that is easier on the valve.

-I also use Specialized "thorn resistant light weight racing" tubes. Marginally better than regular tubes but not as good as the Airloks.

-I've found that Vredestein Fortezzas are better than Michelin Pro Race. Conti Ultras are not bad either. Have not tried Conti Gator Skins as I don't like wire bead (do they have a kevlar version yet?)

-I have a friend locally who uses Armadillos and claims he has had 3 flats in 2 years. I have about 1-2 flats per 1000 miles.
