Saw this in last nite's local paper. Young bloke in a Corsa, rolled it, and was killed in the accident, although his friends got out. Police accident investigators stated that a contibutary cause to the accident was that his front tyres were inflated to 83psi!!!!, while the rears were underinflated to 20psi.
Apparently, it's done to help them do handbrake turns/donuts?

That would cause massive understeer though wouldn't it? Not good for handbrake turns

Understeer was mentioned by the investigating officer, and the coroner, but so were handbrake turns.

So its proof that Nova/Corsa Boyz really do have **** for brains, (or am i just generalising ? )

Same here -- previous car (Volvo T4), new front tyres fitted, driving home and I'm getting massive wheelspin in 3rd and the traction control cutting in everywhere. One front tyre was at 48psi, the other at 28 ...

Cant believe they are 83 psi, sure they dont mean 38psi.

Surely it would blow the fing tyre at that pressure.

I sent my young brother to the garage in my old Micra and asked him to stick some air in the tyres. I got it back with one of the fronts at nearly 60psi!! The car didn't feel quite right (kinda hadr to tell in a micra) but it wasn't all that bad. Didn't really notice it myself for almost a week.

Doubt it. Most tyre fitters seem to overinflate a tyre to get it to 'pop' up against the rim, then they deflate it to the correct pressure. I saw one tyre being inflated to over 80psi before it popped into place.

mark h speaks the truth - standard practise to get the beads to seal.

Yep I'll agree on the 80psi. Got two Toyos fitted a month or so ago and one popped on well easy. The other needed well over-inflating and the sound it made when it popped into place was deafening and scared the **** out of everyone in the garage.

Yeah agree with Mark H they inflate them to over 100 psi in some cases

I would imagine that they were over inflated more to reduce the contact patch for burnouts. The heat generated from the sort of sustained burnouts generally 'performed' would easily inflate the tyre to that sort of pressure

Mr.Manchester

Ive been in a car accident 3 years ago do to a mates car having over inflated rear tyres.
As we hit the bend the back stepped out he controlled it but over steered and we did a full 360 degree spin whilst sliding up the road at 50mph, bounced up a kerb then off some fencing and bent the car round a lamp post as we hit it side on. when we hit the fencing with the back of the car, the stereo came out of the dash and hit me very hard in the chest, as we came to a stop i could smell petrol so i was out of there straight away.

Police put it down to wet road and over inflated tyres

Colleague of mine didn't have a handbook so took the sidewall instruction "maximum pressure 44psi" as the recommended running pressure

Taking my bike on track days, The tyre pressures are dropped from 41 to 30 psi to improve the grip, They get very hot as well and go like chewing gum at the end of each session.
