Air pressure for Grabbers

Tyre laws, as to pressure, are a little on the ambiguous side in the UK. Something like, pressure in tyre must be suitable for the use to which the tyre is being put. So that gives some scope. But be involved in an accident and have pressures other than that recommended in the hand book for that vehicle, then see what some expert will come up with in court. £2,500.00 max fine for having tyres at wrong pressure, if they are deemed to be the cause of an accident. 3 points for one tyre, 6 for two, 9 for three and 12 for a full house.

So I run my front Grabber AT's (or will, they're being fitted next week) at 30psi as the car handles better than at 28psi. Crash into a car who pulls out on me, having turned the steering and slid sideways. Copper checks the tyre pressures, and consults the manual, says they are over-inflated, and possibly contributed to the accident. I then get issued with a summons and a charge for incorrect tyre pressures. Isn't the manual a recommendation for pressures and not a statement? Or am I over-exagerating? I would expect a charge if they were at 16psi and so looked flat.

Thats my take on it.. and I agree they do feel better with 30 psi in the front...

Within the small ranges of tyre pressures that are generally discussed on this board, none of us would have any problems with a slight variance in tyre pressures to those specified by LR. For a start, the air pressure meters at most garages are out (by 6psi in my case as I found out recently), secondly the road surface conditions, temp etc , are all factors.

Provided that you run your tyres at a pressure that provides a reasonable footprint, you won't go wrong if you have a ding. Those that run at ridiculous pressures and wheels/tyres that are way outside the manufacturers spec, risk not only a summons, but their insurance will be invalidated also.

So what is dangerous about following the manufacture recommendations on tyre pressure??????????? Nob head
you have to keep the tyres pressure with in the manufacturer recommendations, which is molded into the tryer not the fookin owners manual, 99% chance the factory installed tryers are not on the vehicle any more. People usually upgrade to a better tryer when the replace them so will void the owners manual air pressure guide.So Feck off

My post describing the tyre footprint and weight of vehicle determining the air pressure required should furnish you with all the information you require - you are obviously not bright enough to understand these simple facts and are willing to defend your ignorance as if it’s a badge of honour – hurling insults that you don’t even know how to spell - so carry on running 60psi like the ignoramus you are - I don't care.

you'd better explain what an ignoramus is

Surely thats a stupid question.

Think you are splitting hairs with that. Pressure will rise as tyre warms drop as it cools. So a couple of psi either way is not going to be considered dangerous i would think. Hand book recommendations by the manufacturer are all they have to go off unfortunatly. Different tyre sizes to those specified may also be deemed questionable. If you were say 8 or 10 psi over or under them, questions would be asked that's for sure. You would be amazed how pedantic expert witnesses can be. As the beak knows no better, he ain't going to side with you, you can bet on it. Dropping your pressures by 10 psi to drive on loose snow, would not be dangerous, but driving on the road with them that deflated maybe would.
