Carerra Fury 07 - Rims too big for tyres?

n707301

And so the saga continues. Most of the bike is now fine, but the wheels, the WHEELS!

I think it's the DDM rims, but to be honest I've not checked.

Getting a type on or off is an absolute nightmare. It takes well over an hour to change from my commuting tyres to offroad Continental Mountain Kings (folding - yes, was told this would be easy.... not a chance!). I'm continually scared I'm going to break my plastic levers, but the metal ones mash up the rims and pinch the tubes way to frequently.

The final straw was when I changed my wifes tyres this weekend. Both wheels done in less than 30mins, by hand, no tyre levers. It was a joy. Oh, and I broke a spoke on my commute to work this morning. On the flat, smooth road. Ok, so I had my son on the back, but he's 12kg's. This is supposed to be an offroad bike!

So, my question is, what can I do about it?

I've tried getting folding tyres. Really, made no difference.

Is there a specific diameter 26" wheels must be?

Should I try different tyres? (so far Continental Mountain King, Gravity, Contact Travel, Schwabbe City Jet and A.N.Other have all proved near impossible to get on and off).

Should I approach Halfords and ask them to replace the wheels?

30 mins! that is a long time.

Broken spoke sounds like a poor wheel build. get ity replaced but expect more to break. or get the whole wheel replaced.

You wheels.

Make sure you are unseating the beads and they are in the well of the rim.

Ah, to be clear, getting the type off is easy(ish) as long as the beads have been detached from the rim (just get it really flat then squeeze them off).

But getting the new tyre back on is a complete nightmare. I mean, really puts me off taking it offroad at the weekends due to the need to spend two sets of 1hour+ swapping tyres along with the sore hands afterwards!

I've been cycling keenly for the last 20 years and I've never experienced anything quite like this. Even my road bike is completely easy by comparison!

nicklouse

must just be a bad combo.

wheel specs can be found on sheldon webby.

but i dont think that the diameter will be off.

I have a similar issue with my rims,(DT Swiss5.1's) where the well in the centre is not very deep and means its quite a tight fit. Try some soapy water on the tyre as you are fitting them, just a little bit of lube goes a long way!
And as for tyre levers, try getting some of these, never had any issues with 'em at all- strong light and dont mark the rims.

That's an interesting point about the depth of the "well" in the centre of the tyre. I'd not thought of that and it certainly sounds like it would make a big difference.

As for soapy water, that might help too! Thanks.

I have the exact same rims on my Kraken... There's nothing unusual or difficult at all about them tbh, and I've had mountain kings on 'em, they went on nice and easy.

I mean, no offence but if you can't fit these tyres, and it took you 30 minutes on the other bike, it's almost certainly technique. The only way it would take most people 30 minutes to change a set of tyres would be if they included the time it takes to go buy them

If you truly meant to not be offensive then you wouldn't have added a childish insult, would you?

Also, I don't think I said couldn't fit these tyres. I did say.....

To be more explicit, to fit two tyres, (i.e. remove wheel, old tyre & tube, fit new tyre, new tube, get the second wall over the rim (the real problem part), pump up and refit wheel) takes over an hour.

As for *less than 30mins* (which I might add was a complete guestimate) to change from knoblies to commuters on non quick release wheels on a lazy Sunday afternoon, I hardly think that's a disrespectful enough time to go picking holes in someones technique.

But... Northwind, if you're in the Glasgow area I'd gladly have you come and show me how to change a tyre. If only to lighten up my day!

Northwind

OK, I apologise, that was a bit cheeky and uncalled for. I was trying for funny rather than insulting but I obviously missed my mark, it wasn't meant to be that unpleasant. Sorry!

But, if you can take the rest of the post aside from that, it does stand IMO, the original Factory XCs the kraken came with were monsters to remove- very stiff wire beads- but the mountain kings and my usual nevegals and blue grooves fitted to the DDM wheels the exact same as they do to my 717s on the Soul, no appreciable difference. 30 minutes is a pretty slow time to change tyres, bolt-on or not, even taking that aside.

So, apologies for the offence, you're right, that was a stupid and unhelpful comment.

n707301

Seems I am not the only one, although being careful I can get the tyre back on without puncturing. But there is simply no way to do it without using levers and a hell of a lot of force.

Hey, no worries. I'm just a bit pissed off with the wheels and a bit grumpy.

So far the rim tape was incorrect causing punctures on the inside/rim side (so to speak) of the tubes, the tyres are damn hard to get back on (as described) and today I broke a spoke while cycling on the flat! I've cycled about 4k miles every year, for about the last five years (commuting, touring, offroading, road racing and triathlons) and I've never broken a spoke like that.

So forgive me if I'm raising questions about the quality of the wheels, but I'm not impressed!

Northwind

Yeah, the spoke breaking isn't right at all, and as Nick says sounds like a bad build, mine have had an utter battering through my incompetent riding and they've needed more attention to keep straight than my 717s, but they still true up fine and no actual damage- not exactly tough, but durable at least. So that's not very impressive at all. Not even I would blame you for that

My rim tape was also wrong, it sat half in the valley and half out so some of the spokes were exposed, I caught it before it caused any problems but it doesn't bode well for the assembly line does it? Both of those things point at bad assembly to me (and before someone slates the Halfords monkeys, these things are done at the factory not in the shop!)
