I always seem to have difficulty seating tires beads on rims.
Any tips or what lube do people use. I've just been using the old standard "soapy water"!
-
I use WD40 on difficult tyres. It evaporates off in a couple of days, and doesn't make me worry about corroding the tyre side of the rim. Plus it works better than soapy water.
Michelin tyres on Takasago rims are always difficult.
-
Supercheap tyre shine - works great for me and it doesn't harm rubber.

Straight truck wash or hand wash, always thought WD40 might harm the rubber.
-
wd40 is made up from fish oil, good on old joints im told as wont harm/irritate your skin ;)
-
Try the zip tie method

cut a beer can in half and go to your local tire service and ask them to fill it up with the tyre soap they use, get yourself a 1 inch paintbrush and cut the bristles to half length so it's sort of stubby and use that to put the tyre soap on, you will do lots and lots of motorcycle tyres and it just makes it so easy

I did a 13 minute tube change the other day from a puncture, wheel out & back in ready to ride (a personal record, yey), but most of the time I drive the wheels 3 minutes to the local tyre place & pay them $10 to change tyres. It's a shit job no matter what anyone says & I'd rather not sweat, swear & skin my knuckles to save $10. I use good old dishwashing liquid with just a smidge of water.

Yep, Gippslander, the way to go. I bought a tub of the tyre fitting stuff from my local Tyre place, good stuff.

Bastard of a job....right up there with cleaning air filters ::) It's even worse of a job now with a bit of arthritis getting to the fingers.
Anyway, I have to do my own as I live no where near a bike shop.
I try to let the new tyre warm up in the sun, but as the days are getting cooler a bit of heat from the heat gun or hair dryer will do the same job. And just like BigK, I use dish wash liquid with a tiny bit of water around the bead. Pump up the tyre to pop the bead, deflate tyre, rinse off soap with fresh water and re-inflate......mount the wheel then crack a coldie.

For most of my life I'd have rather rebuilt a top end than change a rear MX tire.
My life changed after watching Douge Shapinshky (?) demo the correct technique.
I bought a stand, 3 tiny levers, a bead buddy, and a bottle of windex.
Watched the vid 10 times, including a few times as I changed a tire.
Repeat: Life changing.

6 minutes front
10 minutes rear
Changing tyres is only difficult if you think it is.

This.
I remember struggling through 45 minute tyre changes, cursing every moment. Gradually, the pieces fell into place, and now I'm consistently around 10 minutes without hurrying.
Watching Jess Gardiner do two tyres with mousse tubes and an airfilter in a 15 minute work period erases any excuses I might try to make for myself...
-
with the old chengshin horse shoe tubes and an air bottle, a 3 minute puncture repair was my best effort. its all in the placement of the bead into the well and picking the little spot where the bead crosses the rim gap for your tyre lever. there is no doubt an old michi or trelleborg are total bastards to remove and I have taken the grinder to the bead wires on occasion when the tyre levers bend :o >:(
-
I put the tyre on with a rubber mallet :o it works well very little chance of pinching the tube, the trick is keep banging the tyre toward the rim at the point of start and around further as it goes on
I use talcome powder, detergent/water, CRC, lanolin what ever I can get my mits on at the time but prefer talcom powder
yep and Im one of those stupid bastards that uses 2 rim locks :-[
-
Two rim locks and a rock hard old tire make it more difficult for sure!
I recently experienced this fitting a new tire on a friends '81 IT175.
Still managed it without tears. :P

Along with using a good heavy "tire fitters"rubber mallet, tire fitting lube that I bought from my local tire joint, and a good strong pair of work boots with a sharp heel, the handiest thing that I have for fitting tires at home is this;
(http://i150.photobucket.com/albums/s120/coljay/P1030153_zpsexlf9gjm.jpg)
I made this wooden frame sometime last century. It allows the wheel to sit flat and not rock around while working the tire on/off the rim. The next most handy thing is a set of knee pads, as the knees are knackered and don't take kindly to kneeling on the ground for long periods.
I haven't had to change any tires during competition for many years, I used to be able to do both wheels on my 1978 390 AMX in under 6 minutes in "Parc Ferma conditions" when it was in 4 Day trim, but it has turned rims. Best time ever for a bike with std rims and rim locks was both wheels on a Yamaha TT250 in under 5 minutes during the Dunlop Tire Challenge at the Royal Adelaide Show back in 1986. I was working for a Honda dealer at the time, but the local Yamaha dealer let me borrow a TT250 for a day so I could practice on the bike to be used in the competition and work out a system for getting the wheels out and back in quickly.

Luv it beats the hell out of an old tyre ( I use a hard tyre) :-[
Im gunna copy your frame! thanks ;)

I use two locks if I am going to a particular greasy event like the old devils pinch enduro. hit a log in the grass and punctured both tyres in the first section and rode the entire event on flat tyres. great traction. was fine

I agree, that's why I put them up a few posts back (well tried any way)
Stands:
I like my waist height stand like Dougs (in the video)
The ground level one sold at Ballards with the lever built in is handy for breaking beads. Especially Supermoto tires.
A steel trash bin with split hose around the edge is another option.
I have an impressive "no mar" tire changer now, but am yet to bolt it down. A bit over kill for dirt bike tires.

Woops, I shouldn't have skipped to the 2nd page of the thread!! I've watched these vids a few times over the years. I almost have it committed to memory.

For really hard ones to change i finish on the rim lock - allows to tyre bead to go right into the dish as the rimlock can prevent that bit extra possibility
..

Great Videos, check for directional tyres before fitting...
-
good video definatley learnt something :)

Hansi Bachtold was 4 times world sidecarcross champion back in the 80s and he did all of his own tyre changes. And he used a new tyre every time he went out, even for practise....why practise with bad traction??
He spent a lot of time inspecting rims, spokes and fittings for rough or sharp edges.
He always used heaps of talc and checked everything when we stripped it to see any imperfections.
WHY?? Because flats cause missed points and missed points looses GPs and lost GPs means lost World titles.
-
a good tradesman is pretty to watch in any field. this bloke changes new tyres on new rims.... i wonder has he done much vintage tyre changing. The tyres i get are 20years old on even older rims, never that easy
-
A 30 year old Pirelli Garacross is always a pleasure to remove. You can usually take them off with your hands... Or not...
-
I usually don't fork around trying to get old tyres off. Start off with the hacksaw then finish the bead with a grinder.

The McLaren F1 team changed four wheels in 1.7 secs the other night.

A lot of straight forward common sense solutions,thanks!

There's a few "teams" in Western Sydney that can change the wheels in a similar time, but give them a few hours they can have the colour changed, the car "rebirthed" and interstate!

small amount of lube is all i use showed the young fellas how to do it at the dirt track last year they had been fighting with it for about 40 minutes, got it on in about five. showed them the basics and the rule for bike tyres is ( if your fighting with it you're not doing it the right way watched) them do one on a mini that i had a bit of trouble with and came to the conclusion that they need heaps more practice.

The only straight forward common sense solution? Get someone else to do it! ;) ::)
