Puncture ? What puncture ?

About two and a half years ago I decided to chuck a couple of 45s on my hybrid to give me a bit more comfort on what is left of the road surface in the U.K. I do cycle a lot of miles and it was normal for me to get at least two puncture a month with my old 35s, I did not realise it at the time of purchase but the tire from decathlon had puncture protect and to my disbelief I was not getting any more punctures after fitting them. I have had zero punctures for two and a half years !!! I always thought this "puncture resistance" marketing was a load of rubbish but no it actually works and I would thoroughly recommend anyone to get these puncture protect tires as they are awesome. Unfortunately Decathlon don't seem to sell the 45s with the big grip on them any more and I ended up buying in error the tire that I'm leaving the review for. This particular tire has about as much grip as a space hopper and I have to run it low to get any grip at all which causes a bit of drag however fully inflated the bike does roll well, I would advise any one who needs the grip to purchase the 42s which on this occasion I wish I has done. Just a side note when inspecting my old 45s I found bits of glass and thorns dug into the tire and I could literally pick them out as they has got stuck in the tread of the tire and just couldn't get any further Its brilliant !

best price

Buena cubierta

La llevo en mi Elops a diario y no sólo la llevo por asfalto porque a veces es inevitable meterse por caminos de tierra con algo de piedra suelta. Aguanta sin problemas y hasta hoy no he pinchado. Así que supongo que para un uso ocasional y sin agua podrían ser válidas para tierra también. Para niveles mayores mírate unas de trekking.

Buena duración y comportamiento más que razonable

Se comporta correctamente dentro de lo esperado, tiene buena rodadura y no ha dado problemas de control. La duración está ya en niveles muy recomendables.

No para 29

Me vendieron esta rueda para 29, pero no lo es. Es de 28. Puedes meterla a la fuerza, pero no es lo suyo. Así compensa la deficiencia de no tener nada para 29

How to measure tire wear

To measure the wear on your city bike's tires and to know when they need replacing, you need to inspect the tread. Usual signs of wear include: - tread starting to fray - the appearance of a series of micro cracks - low tread depth - the carcass becomes visible. In all these cases the tire is worn and needs replacing.

How to remove a tire

To remove your tire, deflate the inner tube until no more air comes out. Once deflated, use a tire lever to remove the tire from the rim.

How to fit a tire

To put the tire back on, place one side of the tire into the rim. Next, inflate your inner tube to approximately 30% before putting it into the tire (inflating it beforehand reduces the risk of pinching the inner tube). Then, insert the other side of the tire into the rim, starting on the side opposite the valve. Before inflating the inner tube all the way, check to make sure it isn't pinched between the tire and the rim.

How to inflate your tire correctly

Inflate your tire carefully. The recommended pressure is indicated on the side of your tire. Also, before each outing, make sure that your tires are at the correct pressure for your ride.

Tip from the pros

When inflating your tire, make sure you inflate it to the suitable pressure for the terrain you will be riding on and the weather conditions you will be riding in. When riding in rainy weather, lower the tire pressure to increase the tire's traction. On the other hand, when riding in dry weather, you can increase the pressure for better performance.

This expertise is indicated on our range of B'Twin tires with the label "Designed in France."
