Quick one, off to Google the answer but I thought you may all know on here quicker !
We have a Iveco 7.5Te (cough: horsebox) - what's the typical air pressures needed in the front tyre of a Truck like this ?
It is pulling left a little and before I get tracking ans such looked at (which is a PITA as not a Tilt) I should check the obvious !

Obviously not wishing to be an alarmist and ratchet up a risk out of all proportion - but take care inflating commercial tyres. I met a chap at a party a few years back. As we all got a bit drunk, I became aware that the chap had a false leg. As I was a little inebriated, my usual social limits were somewhat higher than usual, so I asked him if I could see his false leg. It was an amazing bit of engineering - all billet alloy and carbon fibre. It was strapped to his left leg below the knee. To see him walk, you would not know he had a false leg (unless he was wearing shorts of course - natch  ) Anyway I digress - I asked him how he lost his leg. He replied he used to work in a Lorry Garage, and he was inflating a lorry tyre one day, when the tyre exploded. It took his lower leg clean off  Turns out that this is not what you'd call a regular occurrence, but it is well documented and happens more than you'd like. If you do a search on here, there are other threads about similar injuries and even deaths from tyres exploding whilst being inflated. As silly as it sounds, whatever tyre I am inflating now - even on a car with a relatively low pressure, I stand well to one side and turn my face away from the tyre.

Ah, 70psi, might be able to manage that on my old Halfords unit - I thought they were all higher than that.
Cheers

Cheers Yes much higher!!!! you need 100psi front and 90 rear... running at 70 psi will result in a blowout or very dubious handling at best!!! im asuming you have 215/17.5 radials....

 Proves that you shouldnt rely on an idiot on the internet, although most of the puddle jumpers that I touch are on their way to scrap.

Surley that is from split rims, ive never heard of a modern hgv tyre exploding and hurting anyone, splitrims however are friggin dangerous, its the ring in the rim that flys out as well not the tyre.

Nope - normal HGV tyres on normal HGV wheels I'm afraid - they're dangerous mate!
