Changing tyres...

[northwind]

So, I have the stuff, I've got the tyres and the already-scabby wheel that it doesn't matter if I scratch it up further, I've broken the beads (using an 8 foot bit of wood and some steps), and I can't get the sod off. Any suggestions? It's a 190 Pilot Power on a Bandit 12 wheel if that's of any significance, so it's a little big for the wheel.

Northy have you got a modded swingarm? Or does a Bandit wheel fit fine?

I guess you deflated all the air out of the tyre? :lol: should be able to get some tyre levers down the side if the beads are broken and lever it out of the rim.

Dunno chum, but I bookmarked this page (http://www.clarity.net/~adam/tire-changing-doc.html) for future reference, as it seeemd to be useful.

Yeah, both beads are totally clear (isn't it great, by the way, when after fighting it for ages it finally comes, and after the first bit the rest just slides off? Lovely!) But when I get the levers in, it's not even close to clearing the rim.Maybe I need to get the tyre more into the centre to make slack...

With a small amount of effort, it fits ;) But I've not got it totally done yet so I don't want to say any more. 21Quest and BILLY both know how, though, it's the exact same as the old GSX1100R wheels with the sloped spokes, only straight instead of bendy. Lighter than stock, too! To my surprise. Anyway, more on that later, today I can't even get the ****ing tyre off never mind change the wheels ;)

Your not going to start the b12 mod are you :D


Have you any tyre leavers you need 2 large one and a lot of brute force
Put the first one in then about 3 to 4 in away put the second one in the work the bean past the rim then remove the first and put it in further around and repeat untill the whole of the bean is past the rim and then repeat for the second bean!!!



well it worked for me

Or you could take it to your local garage and they will do it for you!!!


Cheers BILLY


ps Have you got your spacers made yet?

[northwind]

Ta! Yeah, things carry on at their relentless and terrifying pace with the B12 mod :roll: I got a shop to fit a knackered old tyre (thumbsup to Two Wheels in Edinburgh, who're happy to deal with my ridiculous ideas!) but it's a 190 and had clearance issues with teh SV swingarm. I have a new 180 in the garage which I'd planned to fit after getting the wheel set up and powdercoated, but I'll mount it up just now.

Or, I could go to a dealers ;) But tyres are just about the only thing I keep going to dealers for, so I figure I'd have a crack. All the hardware costs pennies, after all- set of levers and rim protectors from a show was £8 all in, and my cunning bead breaker was free :) Though hard work. I got a set of tyres for about 2/3 what they'd have cost locally so there's real savings there too.

Get one of the G-clamp style bead breakers for the future. You'll not regret it.
You're on the right lines already.

Anyway....
Once it's off the bead on both sides you want to put your first lever in and just hook the lip of the tyre and no more. Begin to prize it towards the wheelrim and squish the opposite sides of the tyre right into the centre of the wheel. Now get the second lever in a few inches along from the first and use it spoon side in so it wont hook on, but slide the next bit over the apex. Repeat til fade.....

The other sidewall will come off in similar fashion, putting the opposite edge into the centre of the wheel recess. You can sometimes just give it a yank with your arm on wide back wheels. Fronts are a whole new class of b'stard hard job.


All this from scrutinneering my mate do mine. :lol:

Don't ask me how he puts on the new one, I've usually gone to make a calming cuppa for him by then, or in extreme cases ordered to get the carry-oot....

I've been fitting my own tyres for about 18 months now. The knack is to, once you have broken the bead, keep the side you are trying to remove pushed to the centre of the wheel, where the wheel well is deepest. this will create enough slack to let you start levering that side over the rim. A pair of rim protecters helps a lot(although you could probably improvise with some plastic or rubber), you will probably use enough pressure to mark the alloy of the wheel, not just the paint :!:

Jeez you guys are making it sound like it's hard. All you have to do is get a couple of spoons out of the kitchen draw. I've been doing that since I was a lad. :roll: :roll:

Can't see any point tbh, breaking the beads was dead easy once I'd worked it out- getting the leverage in the right place so that the block of wood didn't slip off and the tyre didn't tip, was a fiddle but I'll know next time. Funny, i thought that'd be the hard bit ;)

Got one side off eventually... The tyre was keeping it's shape very determinedly, maybe partly to do with it being too big for the tyre, so keeping it in the centre of the wheel in all the places you should to create slack would have needed another set of hands, but I finally shifted it with just a bit more brute force and ignorance ;) No new marks on teh rim either, which isn't saying much with the condition of this wheel...

I figured out why I couldn't shift the other side, but by that time I'd got fed up so I've left it for tomorrow ;) Cheers for the advice folks.
