Is there any limit on the pressure a tube can tolerate? I'm terrified the bloody thing is going to explode.

Speaking of punctures, my luck in this respect is pretty poor. Was out on the MTB yesterday, was about 1.5km from home and suffered a front pinch flat going up a small curb. Stupidly, I didn't have my spares or tools with me (saddle pouch currently attached to my road bike), so it was an uphill trek back home. Nice day though, fortunately.
I don't go more than 10psi over

I had tons of pinch flats until I started running my tires above the recommended psi;
Are you sure you are installing them right? Once you have the tube inside the tyre and both sides of the tyre mounted inside the rim, pump the tube up a little (maybe 30psi?) and then work your way round the tyre with your fingers pushing on the sidewalls to push them away from the inner side of the rim (difficult to explain...). The goal is to make sure the tube isn't trapped between the tyre and the inner side of the rim.

Otherwise I'm at a loss, especially on the super smooth Swiss roads, why you would get lots of pinch flats. Personally I wouldn't want to run at above recommended psi.

Re: Cycling blow out - possible causes?

Bought online, from DE, because it is a much cheaper option.
However, some of the savings could have been made on consumables - dodgy tyres and tubes.
Best course of action is to buy two quality tyres and tubes, replace the failed parts and swap the other original tyre and tube, before that goes pop, too.

A well-known brand, with excellent reviews bought from a reputable dealer. All the equipment is standard. Looking at the damage to the tube, it probably would have happened to any tyre, apart from reinforced makes.
I've already ordered a pair of Gatorskins, I don't really want to be running two different tyres.

Good choice

Most bikes, even pretty expensive ones, come with fairly mediocre tyres. Anyone planning to use a bike for more than just pootling around would be well advised to plan to swap them over.

This one is great on bad pavement but where are the brakes?

Online? If yes, then where did you order them from?

Well you can always keep the undamaged tire as a spare

Amazon UK. If I'd shopped around, I probably could have found them cheaper elsewhere, but I'm impetuous like that .

Spare? Naturally .

Aren't there pros and cons to that idea? Maybe you want something more hard-wearing on the back and something a bit grippy and softer on the front. (That's just a guess though, I'm not really a serious rider).

I've been running Michelin Pro 3 on the front and Contintental GP4000 on the back for about a year (over 5000km) with no problems. (The bike came with those). I certainly check the pressure almost every ride and keep them at the top of the range. Also give them a check and a wipe after riding.

This thread has gone on long enough without any porn: what is the bike, any pics?

I just though it'd be a good idea to have puncture resistant tyres front and rear.
The bike? It's a 2014 Cannondale CAAD8 Sora from Biker-Boarder in Germany.

Both the Pro 3 and the GP4000 are very good quality tyres - I can't see any reason not to run them like that. Having said that, I wouldn't deliberately look for tyres with differing grip levels front and back - going round a wet corner and finding one end gripping and the other slipping would probably be sub-optimal

Re: Cycling blow out - possible causes?

Not had a puncture in over 4 years and I cycle daily, occasionally longish (100km) distances.

I've not read this entire thread but make sure the tyres are properly seated on the wheel rims and that they're the right way round (they should have an arrow showing direction of rotation). Unless you're mountain biking pump up to the max PSI rating shown on the tyre - over rather than under.

I've had 2 punctures on the Cannondale, both from external influences. All tyres were seated correctly; the only issue I might have to adress is slight under pressure, but like I said, I haven't had a pinch flat on the road bike. Yet.

Schwalbe Lugano 700x23c

No idea on protection strip.
I had these tyres on my Cannondale carbon super six and recently got a puncture on the rear tyre...a pinch puncture after going over a shallow pot hole back in the UK...they do have a Kevlar strip but it didn't help in this case....and it happened a couple of days before a charity ride. I replaced it with an 'armoured' Specialized tyre and new tube.
I also slightly buckled the wheel.. I weigh about 96 kg, so I guess that didn't help. :-)

I now need to think about putting winter tyres on them....will look at some with extra protection and forgo the weight difference.
By the way....a new tyre, new tube, fitted in a shop whilst getting the wheel straightened...25 total cost in Devon.....I tried not to jump with joy at the cheeky cheapness of it!!

Re: Cycling blow out - possible causes?

Hmm, the Amazon UK dealer sent me a pair of 700x32 instead of 700x23 tyres . I contacted them and they said they had no control of how goods are displayed by Amazon and the desription is indeed misleading, and offered a full refund including Swiss import costs.
I'm having problems finding these tyres in CH, can anyone recommend a reputable Swiss dealer, or recommend a puncture-resistant tyre similar to the Continental Gatorskins?

Re: Cycling blow out - possible causes?

I buy all my bike stuff from here:
http://www.roseversand.de

It may not be worth it for small orders unless they're having one of their free delivery sales.

When delivering to Switzerland they remove the 19% mwst, add the 8% Swiss tax and charge 1% for doing so. It then comes through Swiss customs duty paid, so not stopped and never any further charges to pay.

Re: Cycling blow out - possible causes?

Since the tire diameter is the right size and only the (cross) section width is slightly larger (+ 9mm) -- provided it's not against your bike specifications or your own requirements -- you might (??) still be able (??) to mount them. The offset will be +4.5mm on each sidewall. I have never tested this before. Your wider tires will last longer than the thin ones (less premature wear), lower temperature and the friction and grip won't change that much.

What you & AdrianLondon think about this?

a) I'm not sure the tyre would fit my rims and
b) I don't really want big fat tyres on my sleek road-bike

Anyway, I reordered from wiggle.co.uk for 1/3 the price (inc free delivery to CH within 6 days)

I buy almost everything bike-related from Wiggle. Worth noting that whilst their system works well, deducting the UK VAT and with free shipping, you should expect a bill from DHL a week or two after your order arrives which will include the Swiss VAT and also DHL's handling fee. Still worth it, especially for orders above perhaps 100 quid, but not quite as good a deal as you may have initially thought :-)
