Cycle tyre puncture - prevention better than cure

As you might have guessed from my previous posts, I am really into cycling now. I even borrowed a couple of books on cycles/cycling from the local library (I know there are loads of information on the net but nothing beats a good book with illustrated pictures).

Anyway, one thing I am really worried about is getting my tyres punctured while riding to the University. I got myself a cycle tyre puncture repair kit. Through it has never happened but repairing a tyre by the side of the road is not something I am really keen on. I tried practising at home using the old bike I am restoring - getting the tube out, trying to find the hole and then patching it up. I have seen YouTube videos and they make it look so simple. Prying one side of the tire bead over the edge of the rim was the hardest.

Here is a popular clip on YouTube on how to repair a puncture:

Searching on the net, I came across a site which sells Amerityre tyres which they claim are 100% puncture proof but they are not cheap. On the other hand, Andreas at the London Cyclist Blog says that there is no such thing as 100% puncture proof tyres. However, there are a number of tyres which are said to have high puncture resistance.

While shopping at Halfords I noticed a green bottle - it was the Slime Tube Sealant. I didn't buy it because I was sceptical and wanted to read the reviews first. Apparently this product was really good with so many positive comments on various sites. I noticed that it was also available at the Go Outdoors store. I later took my bike along on my way back home from the university and bought a bottle. The in-store bike mechanic put the green liquid in both my tyres for free. I haven't had a puncture even once but I do feel much better now.

I now want to put the Slime in all my bikes and doing an online search realised that I could have got it much cheaper elsewhere, with the cheapest online at Amazon Here is a comparison of the prices:

Halfords: £8.99

Go Outdoors: £8.09

Wikinson: £4.97

It may be true that there are no 100% guaranteed puncture-proof tyres, but neither is Slime 100% reliable. I've used two types of puncture-resistant tyres - Specialized Armadillos and Continental Ultra Gator Duraskins. I've had one puncture through the tyre with the Armadillos in about 5,000 miles and none through the Duraskins in almost 10,000 miles.

The problem with Slime is that it adds quite a lot of weight to the tyres, more than the weight added by the Kevlar layer of the puncture-resistant models. It also only works reliably on small punctures.

Personally I prefer the puncture-resistant tyres...

Thanks Steve. I read some comments mentioning the extra weight but I feel the small extra weight is worth the risk.
