Sidewall tear in Michelin(6 posts)

Sidewall tear in MichelinSteve_O
Jun 18, 2002 8:01 AM
I was out riding trails on the CX bike the other day and got a 1/4" tear in the sidewall of my Michelin Mud tires. The tube burst immediately and I used the old PowerBar boot trick to fix it. The tear was a fairly clean cut close to where the knobs meet the sidewall...

Any suggestions for patching tears in tires? I know that superglue has been used successfully on mtb tubeless tires. Any other fixes you have heard of?

These are relatively new Michelins and I ride them up to 70 psi; hence the concern about the tear...

sidewall tears = game over

is that you don't want to be at the mercy of a patched up tyre miles from home - or worse perhaps - if it fails early in the day you could lose a day of riding

how much is peace of mind worth vs the price of a new tyre?

in my experience the Michelins are flat magnets - maybe where you ride is better - but for me they pick up glass, splinters and thorns like nobodies business - I have actually thrown mine away - I think the rubber compound is too soft for on-road/glassy trail use

Muncher, another regular here, had the same frustrating experience and has also thrown his away - when I posted about this a while ago - I think a few other posters advised they'd had problems too with the Mich's

they're probably sweet for racing - but as that's never an issue for me I'll avoid Michelins for the foreseeable future

am now riding on Schwalbe's which are heavier but dependable

shame the green matches my bike!!

If the tear is BETWEEN sidewall threads, you can go to your local sewing shop, buy a little silk, cut a size appropriate to the patch and use a whole lot of patch-kit cement to laminate the silk patch inside the tire, over the tear. The tire will never be as strong as it was when you first bought it, but it will be plenty strong.

I've done this with road tires that I inflate regularly up to 120 psi. I rode on one for 4000 km after I did the repair.

Tires are too expensive to throw away if you can still get some use from them.

I would prob go with MJ and ditch it, to be on the safe side. However, if you want to try to patch it, get along to your local off-road motorbike store, and get some tyre bond from there. You should find a weave material with a pre-glued back (peel off type thing) that will stick to just about anything once and for all. Just cut to fit. I guess you could superglue the split too, just to get a neater job.

I know how annoying it is, but I'd try not to think about the $, and do the safe thing. And I'd get another tyre for non-racing use - I really don't think those Muds are tough enough for general hard riding - they seem to be a very soft compound, and too light.

Hope that helps.

First, I agree with the crowd...a torn tire is never as trustworthy no matter how well you fix it, and for whatever reason, Michelin cross and mtb tires seem a bit more prone to tears than other tires. But if you're like me, dropping $40 on a new tire and tossing a tire with 90% tread isn't the sort of thing you want to do all the time. I've had luck with cutting a 1-inch (depending on tear) piece of road tire sidewall and gluing it inside the torn tire with sewup glue.

I've done this on cross and mtb tires with no trouble.
Thanks for the advice...Steve_O

I was using this tire for commuting to work (then hitting the singletrack afterwards!) when it happened. I have it booted with a Park tire boot and the original PB wrapper and pumped it up to 60 PSI. I made the 12 mile commute home in this fashion; however, now I think it's time to experiment with Velocipedio's suggestion and try to stitch it up... and add some cement...

Until then back on with the Conti GatorSkins...
