Hello all.

Massively frustrated this morning. Bought some new Schwalbe road/OTR tyres to fit on the Kona, and tried to fit them last night.

My existing chunky Specialized tyres came off no problem, but I could not get the new buggers on. I even snapped a tyre lever trying.

Thinking that maybe I was being a dick, I aborted and tried putting the Specialized back on - no problem at all.

What's going on?!?!?! Both tyres are 26 x 2. I'm trying to fit them on Black Eye rims, if that makes any difference.

Cheers
Phil

I had the same problem when trying to fit some tyres before - the eventually went on, just had to keep at it...

Can sometimes be an arse.

Try this:

When you've got one side on, make sure that the tyre is equally sat in the rim - if it is further 'in' on one bit than another it will make it very hard to get on.

Equally, have some pressure in the tube, but not much...this helps a little.

When you start to try and get the other side on, start at the valve end and work round using BOTH hands to 'crown' the wheel - feed the tyre on using both hands, one doing the left hand side, and the other the right - meeting no doubt at a point where you feel that there is no way the tyre will go on!

This is where you get clever - if you're experience you can do this by hand (I've taugh theboymoon how to do this - he was dead chuffed the first time he did it at the side of the trail!).

You will need to 'bounce' or 'settle' the mounted parts of the tyre all the way round - this makes sure it seats evenly and gives you a little extra to play with. Then you can start to 'peel' the remaining tyre on either using your hands (by rolling them) or a couple of tyre levers.

With experience you will be able to do this easily, and without levers; some dual ply tyres are a real sod and always need help, but I'd say 99% of XC wheels and tyres can be whipped on and off!

If you get really stuck, using a little fairy liquid and water solution on the tyre to help lubricate it (or GT85 if you're in a rush like I was once)...

Good advice - thanks. I'll try once more.

Can you elaborate on the 'bounce' - I think this part is the key.

Thanks

You kind of gently bounce the wheel on the floor to allow the tyre to seat. Its most useful when the whole tyre is on the wheel (eventually) before you pump it up to get rid of that annoying wobble that you can sometimes get...

Once you twig the process, you can look uber cool whipping tyres on and off quickly biggrin

Ah. I thought the bounce was a method to free up some slack before you've got the whole tyre on.

Bugger.

I wasn't even close last night. There was a good 10 inches still off the rim, and the f'cker was so tight I near broke another lever trying to get it off again!

Good luck, I found this as a kid, some tyres are a complete pain in the ass, I remember one set I had to go to the bike shop to do.

There is a certain knack to it, putting pressure just in the right place on the rim and lever, trouble is when you get good at it all your mates ask you to do their tyres!! More tyres you do the easier it gets, plus it builds strength in your fingers and hands.

There are a couple of cheats though:

Firstly (as already said) I used to grease the lip of the rim where I couldnt get the tyre over, this used help massivly. Afterwards I just throughly cleaned it all with a degreaser and all was fine. Messy but gets the job done

Secondly you could get yourself one of these:

They really do work, they really help with difficult tyres and speed up puncture repairs on the road, but they are flimsy if you use them incorrectly.

Good luck!

It can be - just try it and see.

Always start from the valve end, and make sure you haven't pumped the tube up too much.

The way I got the 1.3 conti sports slicks on my rockhopper was as follows.

It got to a point where I didn't think it was possible, the way to do it IMO was get the tyre on one side, then get as much as you can on the other side, and when you have that last bit left that seemingly is impossible to do..

Get two tyre levers, get them under the lip and force them inwards, so like a pincer movement, it does take some strength to hold them in there and not slip, but I found that after having done this with the first tyre 20 minutes later, the second one took 1 minute.

I find it helps to keep the bead of the tyre down in the well of the wheel as far as possible - gives you a little bit more to play with, but means you need the innertube to be virtually flat, so watch you don't pinch it.

Is it the first or the second side that you're struggling with?

The second side. I'm 98% there - I just cannot get it on, and it's not even close.

My old (When I say old, I mean existing - it's fully treaded) specialized tyre took a minute to put back on, which made me wonder if it was me or the new tyre.

This is a similar trick a mate taught me (hard to explain in words but I'll try!):

1) Get both beads into the centre of the rim at the valve end (make sure there's no air in the tube)
2) Rest the wheel on the floor with the valve end at the bottom
3) Stand with your toes through the rim, either side of the valve
4) Grab the tyre with one hand either side of the valve and pull it tight, feeding both beads into the centre of the rim as you go
5) Keep working your way up to the top of the rim, pulling the tyre upwards as you go
6) When you're at the top, you should (if you've done it right) have enough slack in the tyre to simply push both beads onto the rim

This method has yet to fail on double ply stuff on some pretty thick rims smile

Interesting - you worded it well. I'll give this a shot as well.

If you've got time, leaving the tyre overnight inside out can help, particularly if you leave it somewhere warm to make it a little more compliant.

The good news is once it's been on for a while you shouldn't have so many problems in future.

you gotta get that tyre bead into the central deepest part of the wheel rim well at the bottom and sides to get yourself wriggle room at the top.

yes That's very much the trick the the method I described. It also works when you have to remove the tyre from the rim smile

Thats the key right there.

You soon learn when you work in a shop and you are doing the whole 'yes madam of course i can put a new tube in that for you, ill be 2 minutes' routine.

I just get the seated side of the tyre in the centre of the rim. You're usually left with 10 inches or so that won't push over, so I just leave it for an hour and try again. It'll go, although you may end up with blisters on your thumbs smile
