While we don't do product reviews, note that puncture resistant doesn't mean puncture proof -- with any air based system, you're going to run the risk of cutting the tire and tube and getting a flat. Some tires are better than others in terms of puncture protection, using things like kevlar belts. The tires you bought trade off for some more the weight and ...

Bald-ness isn't a problem on tires used on roads. In fact, it's favorable. I'd replace the tire once I start getting flats (or a bit before), or seeing canvas. The primary advantage of tubeless would let you run lower pressures (since you can't pinch flat a tube if it isn't there) which is useful for running big tires while mountain biking for more grip ...

As usual, Sheldon's got the answers. ISO 622 is the unambiguous way of referring to the following rim sizes: 700c (you see this marketing on road, hybrids; this is from the French system; the c is often dropped, but there are rare a,b sizes) 29"x decimal (you see this on mountain bikes; usually only applied to wide rims) 28"x decimal (particularly in ...

Your bike had these tyres as stock in 2015 Cross 40c Front - Cross 40c Rear according to http://www.tredz.co.uk/.Merida-Crossway-40-2015-Hybrid-Sports-Bike_74298.htm 2014 version was listed as Tyres: Cross 700 40C So you have a 700c rim which can take a 40mm wide tyre. Confirm this by looking at the sidewall of the tyres, it should say 622-40 or 40-622 ...

What can you afford? If you're not really struggling financially you should replace the tire. If you cannot afford that (or if you need a temporary fix while you're obtaining a new tire) then you need a "boot" inside the tire. A "boot" is some piece of flat material (typically about 5 cm x 5 cm, though size can vary based on tire size) that is flexible ...

There are two ways for air to leave a tube - an actual slow leak in the rubber or a faulty valve. Since you've checked the tube and changed it. this could be a technique thing where you're pinching the tube creating a small hole that is not big enough to show up in a water test. Try inflating your naked tube to a pressure of about 10 PSI. It will double ...

The size of the puncture really dictates whether a new tire is in order... that being said, if you patch your tube and inflate the tire (the one with the puncture) you want to make sure the tube is not exposed through the puncture hole. If you need to ride and the tyre is questionable... an old trick is to put a dollar bill or power bar wrapper on the ...

That's thread from the layer of fabric they use to cover the tire bead, they sometimes fray a little, just cut them off, they're not part of the tire structure.

Well, it'll depemd on how the narrower tyre sits on the rim, specifically whether a 25mm tyre will be wide enough, but as long as this is ok, you should be fine. Be aware that wider tyres will have a larger surface in contact with the road, and therefore more grip, but if you're happy to trade that off, go for it.

If you purely have a puncture by a pin, small nail, or fragment of glass, and the hole in the tire is just a puncture and not a slit, then there is no need to do anything special with the tire -- just put in a fresh (new or repaired) tube and go. You do need to be concerned if the puncture somehow causes a cut in the tire, with a dimension of more than ...

Is there a reason they call diaper nappys? or elevators lifts? It's the queen's English. It differs from us american folk. In British English both spellings are correct, but both words mean totally different things. In all of the English speaking world, the word tire when used as a verb means to become exhausted/sleepy. In Britain and many ...

measure the interior rim width (you need to remove your tyre to do this) look at this chart, from Sheldon

I would check your tire for tiny tears along the sidewall. I had a problem with my tubes leaking as well until I figured out that the tube was expanding into the tear of the sidewall and getting pinch flatted. Although, a slow leak is a little strange. If you don't see any tears in your tube, try replacing your rim strip, since it does seem to be acting ...
