Just fitted a set of 2.3 Mountain Dry and the wobble on them is causing the front to rub on my rigid fork.
The rim is true, so I'm assuming the wobble is because the bead hasn't seated on the rim uniformally. I've tried reseating it a couple of times but the wobble is still there.
If it's definitely a seating issue I'll just keep on trying, but is there anything else I could be missing?
Forks are bent, dishing is out, not in drop outs properly.
I wouldn't ride it personally, sounds like a death trap!
Probably not seated or a bulge in the casing. Anything else would have caused problems with any tyre on it.
@sh1tforbrains
The forks aren't bent and the wheel is def well in the drop outs.
It is dished slightly off centre (cheap machine built wheel) but not horribly so.
Not riding it anywhere at the moment, waiting on some new shifters and need to find an extra headset spacer yet.
@shandy
Did wonder if it was a bulge in the casing, though being Michelin I'd have hoped for a bit more quality control. But then again they were only £7 each...
Why didn't you say they were Michelin's. I've had this problem before, they're crap tyres for sure.
Cheapskate!
try some water mixed with washing up liquid spread around the bead. sometimes the bead can be abit tight if new so it helps them seat properly.
Same issue on my Michellin XCR AT's. Tried over and over again. Anyway, in retrospect they are rubbish.
Bums. Might have to send them back to CRC in that case.
Or buy a new set of forks with bigger clearances. That's usually how I solve simple problems, spending loads more money than intended.
I find they seat better if you blow them up to about 60psi then lower the pressure to the level you want.
tony24/budgierider - those sound like good ideas, shall give em a pop when I get home.
This is my budget bike so I'm loathe to spend a penny more on it than I have to.
If they are not tubeless could be a crappy tube...
I had it happen on a brand new nobby nic. Eventually got it replaced FOC, the tyre.
I had this problem with a set of Michelins that came with a bike - no matter what I tried they simply wouldn't seat evenly in the bead.
Binned them
Is there a mould line around the walls of the tyre ?
If so, make sure it's the same distance from the rim all the way round.
Sounds like it's not seated correctly.
As advised above, let the tyre down flat, plenty of soapy water between the tyre and rim, blow it up to 60psi, let it back down again to the pressure you want.
It should pop out in to place.
Nope, no obvious mould line that I can see. They are the folding version, I've always found foldable tires harder to line up, but never quite to this extent.
Probably not helped by the fact I'm mounting them to cheap no name rims.
As has been said already soapy water & high pressure I have gone as far as 75 psi before they popped in.
I very much doubt it is your rims at fault.
Two other things to try:-
1) Take tyre and innertube off rim and check rim tape hasn't migrated up into the groove, preventing tyre from seating properly.
2) With washing up liquid applied and pressure up to 60 psi, lay wheel flat on floor and carefully step on the [u]tyre[/u] where its not seating properly. Should push tyre away from rim in the area and give it chance to seat under the pressure.
