Found the puncture protection limit of Schwalbe Marathons!!

And a slime inner tube - apparently all these measures can be undone by a well placed 2 inch nail on the road. Right through the tyre and tube - with lovely slime all over the inside of the tyre to make putting it back on the rim (with new tube) nice and difficult

Was going down a hill when I lost the rear wheel pressure and the nail has made some lovely marks on my frame - speaking of which did anyone watch the "Cycle Show" this week. They made such a big thing about rear wheel punctures. It's not that BIG a deal!! Brake gently and change. Simples!!

I had the same thing a few weeks back (no some though) and can't understand how a nail could have been at such a perfect angle!

In my case it was sat in a pot-hole which I failed to dodge. Guessing the fall at speed gave the nail the momentum it needed to get through.

I had a massive thorn in one of my marathons a few weeks ago - the slime tube did its job though and saved me a inner tube change, just need a few puffs of air in!

I just wish I had a car behind me dishing out replacement wheels/bikes. I might have made the train for the middle part of my commute then.

Actually serious question now - one of my tyres now has a hole / rip that I can almost fit my little finger through. I can't afford to replace the tyre, so do I need to bother reinforcing it?

Hrrmmm good question on a road bike I wouldn't want to ride on a weakened tyre at all. Too risky to suddenly have the thing fail at 30 mph downhill.

If it's not on the sidewall on say a fat mountain bike tyre I might be willing to jam something in there to hold the tube in while I cycle very slowly to get another tyre.

+1 to this. The hole in my tyre is small - will see me out until late Autumn when I switch to treaded tyres - then a new one for next year. If I had a hole the size of the one you're talking about I'd be ordering a new one now.

You need to 'boot' any big hole. Some stiff plastic might help.

I can vouch how 'hard' thorns are. Pulled about 6 out of the sole of my walking shoes this week - been trimming hedges then walking to my folks house wondered what was sticking in my foot. Bloody thorn. Found 5 others, some a good cm long.

Are these normal Marathons or Marathon Plus btw?

Two weeks ago I had a fat shard of glass manage to get through. Having cycled round there again, im fairly sure what happened was that I was leaning a fair bit cornering through an underpass exit and the shard managed to go through the edge of the puncture proof blue strip where its thinnest. Having pulled a drawing pin, flints and thorns out of my M+ with no problem ill let them off with this one fail.

 

[Andrew_Culture]

Mine are Marathons, they don't make Marathon Plus for bikes as old as mine!

I'll re-enforce it as I have straight sided rims, with no lip inflated to 95psi

A one inch nail went through the M+ on my MTB a couple of weeks ago. It must have been pointing almost straight upwards. I still made it into work about half a mile further on before the tyre deflated. It's the only puncture I've ever had on an M+ and one consolation with those tyres is that if they do puncture you shouldn't have any trouble locating the cause.

A two-inch nail? Pah! It took a six-inch nail to puncture my Brompton marathons.

We've also suffered a deflation on the tandem (M+) caused by a half-inch shard of stone sharp enough to cut yourself on - after about 40 miles of unsurfaced bike route earlier in the day. That was a complete swine to find, and once founf very difficult to extract. Again, it went to one side of the protective layer.

Back wheel? If so, probably kicked up by your front wheel. I once cycled over a discarded Stanley knife blade. Front wheel kicked it in the air so it was in a ready position to slice neatly through my back tyre: bang! Lucky it was a mile from work, as I don't carry a spare tyre on my commute.

(not marathons, but I think even a marathon would have been brought low by this)

This thread is worthless without pics!

I think this is the limit for Schwalbe luganos! I had to physically unscrew the offending item to remove it!! lovely light tyres, decent puncture protection and rolls well
