Hi all,

I've been using Michelin A1 Aircomp and getting flats like every 100-150 miles. Could anyone recommend tubes that are more durable?

Thanks

I doubt it's the tube's fault. A burr inside the rim. Something sharp still stuck in the tire. Low pressure pinch flats ....

Riding in debris, like that found on shoulders.
Hitting objects.
Worn out tires.

All the above and possibly also just an old, thin tread tire. When the tread wears down, sticks by little road debris are more likely to cause a flat.

The tires are relatively new, ridden for less than 500 miles. There's a lot of debris and potholes on the roads though.

You could get tougher tires (what are you riding now?), or possibly tire liners. Another option is using sealant.

The "Airstop" is a little thicker, but if this is all due to road punctures it won't make much difference.

I have Pro4 Service Course (23mm front and back) and want to try out Conti 4000s (23mm front and 25mm back).

I currently use 4000s and Krylions (now called Pro4 Endurance). I get better flat protection and mileage from the Krylion, although it is marginal.

The 4000s rubber seams softer and stickier, and junk can get on them and gradually work their way in. I still get occasional flats with the Krylion, but they tend to be a single poke from a long wire rather than a slow bore from a tiny shard.

I still wouldn't expect moving to either to more than double your mile between punctures, so you still might want something tougher.

After you flat, make sure you check for any sharp bits still stuck in the tire.

It helps to take the tire all the way off and turn it inside out. Those tiny sharp wires can be maddenly difficult to find.

Thanks. I'll try it next time

My experience with sealant is that it's all but useless in narrow, high-pressure tires like 700x23s. The pressure is too high for the sealant to seal - or stay sealed.

And it will completely muck up the valve to boot.

My experience is these two are very similar in terms of flat protection.

A good habit when you get a flat is take out the tube and leave the tire mounted. Match the hole in the tube with the same spot on the tire. Then it's easy to find what caused the flat. Most likely there's something in the tire that's causing that many flats
