Mounting a tyre
Discussion
I am practising mounting tyres and I am have alot of problems doing it.
I don't have any issues getting it off, and I don't have issues getting the bottom bead on, but I am having big problems with the top bead.
It's all standard, normal 18" oem alloy and a 245 45 18 tyre again standard.
I have an issue where I start going around the top bead, I try to keep weight down but as soon as we get halfway, and progress around it starts popping off the otherside no matter what I try and do :/

if the blue arrow is direction of rotation, it looks (although this could be the photo) that you are using the arm incorrectly, and what its actually doing is pulling the tyre away from the bead.
Are you getting the tyre properly aligned onto the rim?
Where are your tire irons- if you get really desperate you just use a tire iron to hold the bead onto the rim at the initial point of contact.

Assuming that it's rotating clockwise, then it's looking OK apart from where you have that blue arrow at the bottom.
The sidewall (bottom of photo) needs pushing down so that the bead sits in the well of the wheel.
This will give you more room to throw the rest over.
As it is, the bead looks to be on the rim, so you'll really be lucky to get it on, especially without damaging it.
A bit of weight (15 stone or so) will help.

As others have said, a lot of weight on the 7 oclock should get that on.
I can mount smaller tyres ok, but yesterday trying a 265/30 R19 Bridgestone (known for their solid tyrewalls) me and another guy failed massively. Machine lost grip of the wheel, bead sounding like it was cracking, couldn't even get it 2/3rds on.
We got the experienced guy over, he did exactly the same as us and got it on first time. We asked what he did different and his answer was brilliant, but also probably correct.

If you're just testing, go for it.

I tried putting weight on at 6-7 oclock area but then the head area just pops right off.
It's like a mix of trying to keep the head on and keep weight on the 7oclock area to make sure it isn't coming back out.
Point taken, going to clean off all the lube and try again.
Made a youtube video of my failure May help another newbie!
Uploading now.
Thanks for the help though!

Hmmm watching the video shows me panicing too much much about the head slipping off and no weight going on at 7 o clock area.
Any other pointers?

If I put my weight at 7 position then the head just slides off and the tyre goes under it instead of staying on top :/

Shave your head, wear Rigger boots and a boiler suit, slouch a lot and reduce words to just either single sylables or the word fk, stick a fag in your mouth and call yourself Darren, you are now a tyre fitter.
Yes, a bit snobbish, but my middle name is Darren and I have fitted the odd tyre in the past so am allowed to comment.

First save some skin by either turn your hands around so your fingers are away from the rim or by pressing down with your fists.Any other pointers?

Lift the left side of the tyre up higher before you start so that it is properly hooked under the lever
Press down on the tyre around the 4 o'clock position harder than you are doing in the video then keep pressing down and follow it around to the 9 o'clock position where the tyre should pop on to the rim.

i use a bit of leather and a metal bar with a plastic sheath. simply stick the bar in and hold it down. it really is easy dont use your hands like that +_+
Interesting, where should this bar go. My issue is when it comes to a decent alloy and not damaging it.I think we should have a collective PH video where everyone posts up how they mount it
I practiced on a van wheel and did that with no issues in a minute or so!
