Tight tyre

[TAV]

Hi ive got a scott usa with shimano wheels the problem is the tyres are hard to get off ive looked at the rims it says 13-622 but the tyres I have on them are 23-622 on them is that why I cant get them on and off without nipping them are there tyres out there for the wheels because all they say is 700c by 23 on most of the tyres

700x23 should be ok, just as an example, most of my wheels are 15-622 and I use 700x23 and 700x25 tyres, the first number is a reference to the width of the rim.

Here's a link to the Sheldon Brown guide to Tyre Sizing Systems, look for ISO/ETRTO, there is a useful table somewhere down the page that suggests that 700x18 to 700x25c are sizes of tyre that your rim will accept:

I always advice people to take off and refit a tyre 10 times somewhere nice and comfortable, front room in front of Tele type of thing. Do that and you will find the task a lot easier in the cold wet days.

Its hard to get the tyre levers under the bead that's the problem and when you put the tyre back on its super tight

Some tyre brands are tighter than others, but practice and using the right technique can save you hours of cussing.

I find this video really helpful, especially the bit about getting the bead of the rim into the well of the rim to aid fitting:

I must be a lucky guy, I have never had this problem in over 44 years of owning bikes.

I feel there are a few things very wrong with that film, and have pointed them out on here many times.

cheers for all the help what ill have to do is try a few different brands and see how it goes, winters going to be here soon I don't want to be stuck on the side of the road holding all the boys up as I try and put the tyre back on the bike with cold hands cheers anyway tav

1) Ensure that ALL the air is out of the tyre
2) Squeeze the tyre into the well of the rim all the way round the tyre, and keep doing this while you work with the levers.
3) Start at the valve part of the tyre as the opposite side non-valve part will drop further into the rim well.
4) When replacing the tyre, finish at the valve part!
5) A new tyre can stretch if you keep the pressure higher than usual at first, to make future removal easier.

Try a VAR tyre lever. It's designed with just this issue in mind.

Talcum Powder really helps, not much use at the side of the road mind you :-)

Hooray! Ten posts before somebody suggests TALC, nature's best natural lubricant for sticky new rubber.
