'Upgrading' to skinny tyres pointless for London commuting

lolz..
Do they use lead for puncture protection?
Had a set at some point. Felt well proud of my self once I'd pick up speed.
Dunno what size they where, though, they did have something like 700+ g.

Luckily they where as comfy as if made of lead. Seldom felt glad the shitty bike with them tyres got stolen..

Schwalbe claim weight.

What's heavy for tyres?

About 1% of the total bike+rider weight.

If you're going downhill faster than other people, you probably need to lay off the pies.

Find tyres you feel confident with in wet and dry. There are marginal weight gains, but body mass, riding style all need to be taken into account.
Most tyres are vulcnised in manufacturing process, which molecularly binds the rubber tighter to the base skin. Downhill tyres went through a phase of using Kevlar walls, which had massive weight increase, but when you're pounding down 35% Hills over rutts and scree, weight is pretty much the last thing on your mind.
Go for what you trust round town, work it with your mass, overall loaded weight (bike included), and set pressures to suit maximum load.
The tube will blow before the tyre will, but overload it and you'll pop the rim. downhill racing does teach some transferable skills. As does years of rubber moulding knowledge.

Trust it, ride it, carry on.

Interesting thread with excellent banter.
I spent the last year on a pair of 20c hutchinson winter kevlars. Horrible ride, always run at excessive hipster pressure. They're weren't much fun but 'felt' quick and no punctures/problems while I used them. They suited the build tho for what little that matters.
Now on 23c and it feels like heaven.

Fuck him and fuck his boring voice. He is an affront to science. I bet he runs 28c at 50psi front and back. Yawn.

@ Tiswas.

Patronizing, maybe, but I'm not as thick as two short planks.

1 - Nil to me.

Good luck, and have a good day. This whole thing was resolved long ago.

This is a laugh isn't it.
Am I in the minority by using 23mm tyres pumped up every week to their 120psi max whatever the weather?

I do 120psi rear wouldn't have that on the front though!

Neil, it could be Neil?

I do this because I'm not a tyre/rolling resistance dork like all the other OCD loonbats in this thread.

wider tyres are less prone to puncture

A tyre that presents a larger contact patch gets less punctures despite encountering more flints? would live to know the science behind this.

Sounds like a case for...

SUPER MDCC !!!!

Riding at 120psi on clinchers is for masochists, unless you're ~100kg (in which case you'd be better off running 25s at <120psi anyway).

We've done this to death in other threads.

Thread synopsis please?

All tyres are equal, but some tyres are more equal than others.

I bet there's a strong correlation between people who pump to the max and people who make sweeping statements about X tyre being shit in the wet.

Idiots.

Is there an echo in here?

Skinner smaller tyres have less contact point so says 80kg will be on that tiny area thus more likely to get sharp debris embedded.

Wider tyres - more contact point, but weight spread around that contact point thus less likely to get sharp debris embedded easily.

I hope I explain it properly.

But by having a smaller contact area tyres are less likely to encounter debris in the first place. Which means larger tyres are not less likely to puncture.

There are no other threads. This is an amalgamation of hearsay and speculation, with a smattering of maniacal fanaticism. Reads like any other to me.

doesn't sound like science.

I'd imagine on same model tyres it's not true at all, however traditionally wider tyres of differing models tend to be less racy and have more material and pucture protection, which has probably led to this belief.
