Changing a wheel/tire?

[DEL 707]

Thanks for all the replies.

I've been over the tire multiple times, never found anything and I've never been able to find the puncture on the inner tubes, it's always been a slow puncture.
Pressure wise, the tire says between 50-85 PSI, I always have the tire at about 65-70.
I really just want to change the tire at the moment, but I have no idea what to buy. The writing on the tire is 47-622 (700 X 45C - 28 X 1⅝ X 1¾)

Can anyone recommend me a tire? Most of my journeys are on road, cycle path, with a few gravel paths thrown in.
Also can you recommend me some new innertubes?

Don't give up. Have you used the bucket of water method to find where the puncture is? If no bubbles, then can't be punctured. Could be the valve, but under water, you should see bubbles.

Try inflating the inner tubes (not in the wheel) and leave them overnight to see if they go down.

good luck

Tried the water method, I even took 1 of the inner tubes down to halfords to get them to have a look and they couldn't see a problem.

The puncture is really slow, on the last inner tube, I pumped it back up, went out for a 40 minute ride with no problems. Left the bike in the garage and the next morning it was flat as a pancake.

It's a mystery!

Still should be able to see bubbles somewhere, even if it is a slow puncture.
Any where near Longfield? Send me a PM if you are.

Slowmotion is right. A stonechip could be caught in the tread and they can be a devil to find.

If you change the tyre, change it for a schwalbe Marathon Plus and your puncture days should be over.

Unless, like me, you go through about four inner tubes, putting holes in them with the tyre levers, whilst struggling to fit them! I have seem the YouTube videos of how to fit them, but it still takes three men and a horse to get the bloody things on! They are damned good tyres though...I did 8500 miles without a puncture on them..

I have them on all my bikes and they are a doddle to put on if you use plastic tyre levers and not metal tyre levers.

If there are definitely no holes in the tubes then I don't think replacing the tyre will help. Either they're leaking round the valve, through the valve or just through the tube surface over time.

Did you say they were Halfords own-brand tube? Maybe try out a better/different brand in case you've got a dodgy batch. Tubes aren't expensive so it shouldn't cost much to try.

What sort of valve do they have? If Presta are you tightening the cap back properly? I don't know what happens if you don't do that - hopefully someone else can tell you if that would cause a problem.

You should inspect your tyres carefully for cuts and gashes every month anyway. While doing so, check for slivers of glass or grit embedded in a cut. A very bright light helps with this task as glass will often gleam.

Everytime I use the plastic ones they snap !

 

[Sharky]

+1 for metal tyre levers. Very rarely need anything for putting tyres on, and metal ones give that confidence factor, knowing they won't let you down. Have had several plastic ones snap on me.

Also annoys me when you buy those repair packs and it includes tyre levers, but only two. Always use three.

 

[fossyant]

Check there is nothing in the tyre. Had a staple stuck in mine and it was a bugger to find as most of it had snapped off.

 

[gaz71]

Have you checked your wheel to make sure a bit of spoke hasnt come through?

Its probably been said but when/if the tube goes again when you take it out keep an eye on its orientation with respect to the tyre. Pump the tube up and note where the hole/holes are in relation to your rim/tyre. On the inside, its the rim, perhaps damage, loose spoke or rim tape. On the outside probably the tyre, damaged somehow, perhaps a foreign body still embedded. If it two holes on the inside, towards the side, it maybe the classic snake bite (pinch p'ture), you're tube is too soft to start with and getting squeezed between the tyre and the rim when you hit a bump. That list is not exhaustive/definitive though and meerley a guide.
