Fitting tyres yourself

Leave him alone... he's buying my old speedos :wink:

Is that really the sort of thing you want to advertise on here? :roll:

:lol: what?? Nothing wrong with 'previously enjoyed' swimming trunks :lol:

 

And as it happens I was actually eating at the time

[dinkus 10]

Oh and don't even consider trying to fit them yourself, I've replaced go-kart tyres before and that's a right c*$! of a job, let along a full size car tyre with nice steel bands in it!

Therefore with 100% nitrogen you get no leakage and the tyres remain at a constant pressure.

I had read about that. Water vapour molecules present in air in tyres also escape thro' the tyres by osmosis and assist deflation. I became interested in this as every time I went to use the C for a longish journey, I found that one or more of the tyres had lost pressure. I purchased by mail order some American goo called UltraSeal (50 squids worth for 195/50s) and have had no trouble for months.

So pleased with it bought some for the Pug 205, too.

My son's C also suffered from loss of tyre pressure before he sold it. "Expert" told him that corrosion where tyre rim meets wheel means you lose pressure. Repolishing by specialists can solve, but I went for the UltraSeal.

Ive never heard of the Nitrogen for Tyres on HGV's

 

we operate a flammable tanker fleet and the only time our alloys go down is when theres a build up of crap on the inside edge of the alloy inside the tyre,if its leaking on the rim,its nothing a grinder wont cure,prefeably when Im not there :wink:

 

Theres a van up here that goes round offering to fill your tyres so theres no more punctures,its probably liek the old tyre weld EEK !

 

My worst day was a 195/50/15 michelin with 30 miles wear on it ****ed until I got a factory repair :D :dorky:

some of your mates are bound to know a tyre fitter or a man that can,

The pros use washing up liquid to break the tyre/rim seal apart from that I cant help

[Supercharged 2]

Yes, alot of tyre pressure loss is due to dirt and corrosion of the alloy not allowing the tyre to seal correctly but UltraSeal is amazing stuff, My dad has used it in his BMW 1150GS since a nail cost him £100 for a new tyre and its fine, does not affect balance etc as long as you go for a spin just after putting it in so it spreads evenly. We first saw it on a stand at the bike show a couple of years ago and the buy just kept punctering the wheel, in the end all you could see were holes in the tyre but it was still inflated.

According to my online sources, compressed air is made up of 28% O2 and 72% Nitrogen and it is the O2 that leaks, causing gradual deflation. Well, when I say leak, it seeps gradually through the tyre as it's porous. The idea of Nitrogen is that it *should* maintain a constant pressure as there's no 02 to leak. Some HGV operators use it as every mpg counts when you're on the roads constantly and obviously aeroplane tyres would see a pressure drop during every landing.

 

F1 teams use it to keep the tyres at the optimum inflation for the tyre's life, which isn't long in their case!

Oh and I also noticed that any effort put into finding a light weight wheel is soon negated by the weight of the tyres! They weigh a bloody tonne!

''kevhaywire, obviously aeroplane tyres would see a pressure drop during every landing. ''

 

Nah, tyre pressures increase during landing due to excess heat from the brake units etc. Nitrogen used in aircraft purely for safety reason of not supporting combustion. Tyre pressures checked routinely when wheel / tyre is cold.

Are you an aeroplane engineer or something? :lol:

Why pay for Nitrogen when air is free!!! :|

And air comes with free nitrogen, too! :)

Damn, I've been rumbled! :lol:

If you ask kvwloon, nicely enough, maybe he can get you an aircraft fuel tank inerter!! :idea:

It takes O2 out of air and turns it into nitrogen for you? :smurf:

ATS charged me £5 per wheel,,,chek em out if ya like

you can get air seperators for beer gas its about the size of a tv monitor

we can save 1/4 of a tonne/ton on a set of 6 alloys compared to steels

and they tend not to crack either

in our case they went one better and just lightened the tank and went back to steel wheels,yes god knows how AtS manage to move the tyres without dropping a bollack.

Allcoa alloys are well cool 8)
