Safety, large tyres

sevenhills

Some of our new company vehicles have large tyres with pressures to match, 83 psi
The vehicles we use now, VW Crafters have 61/65 PSI


I have read that when doing pressures so high, above 70psi, a special wire cage should be used; I assume that is just for tyre fitters when changing tyres, but not sure.

Hopefully your employer would be up to date on these things (what have you got with 83psi tyres?)

Both recommend cages or covers/barriers when dealing with 70+psi tyre inflating.

Its a Fiat minibus with 225x75x16 tyres, like the one in the link.
Our VW Crafters have a recommended maximum tyre pressure of 61psi, but on the wheel arch it states 65psi, they must know better than VW.

What else could it mean? Fitting cages when parked, or when driving?

I used to top up tyres to 330 psi without a cage, changing a tyre and inflating from flat was an entirely different matter.

I have heard a truck tyre blow and its like a bomb going off. Luckily there was nobody anywhere near it. The guy had come to the front to sort my tyre out.

I had one blow on the motorway and it cleared all the traffic.

You have company vehicles and someone should be in charge of the paperwork and put into place any equipment required for their use.

I don't drive these vehicles, but I know we dont have any cages. I don't want to create a H+S nightmare, unless needed.

The only time you need a cage is when fitting a tyre and seating the bead on a rim, you have no issues.

I witnessed an artic tyre blow up in the face of a driver at a motorway service area. The guy was staggering around and was led off by staff, don’t know what happened after that. Certainly a loud bang, I was about 50 yds away

And when the tyre fitter comes to replace the blown out tyre on the lorry he doesn't use a cage even though they're inflated to 130PSI.

Yet to see a HGV tyre fitter or HGV garage using a cage since split rims became obsolete.

Same with have treads recut, they are supposed to deflate the tyre. Most don't though.

What could go wrong with a truck tyre between your legs whilst holding a heated sharp cutting tool? Nope sounds safe to me.
