Re: Tyre pressures
This reply is going to be quite lengthy but I think it is worth thinking about.
I agree re different conditions etc require different tyre pressures and tyres.
Manufacturers I am sure spend quite a bit on research and give the tyre pressures which give the best compromise for use on ordinary roads in general everyday driving. They no doubt take into account safety and wear rate before issuing the figures.
The first of the important bits in my opinion - in the event of an accident which involved investigation by the powers that be, if they concluded that the tyre pressures were not within the manufacturers spec (give or take the normal variations within operating conditions) and were a factor in the accident , what then?
The second of the important bits ( not pressures but still on tyres), again in my opinion. A few years ago I read an article re a crash. The motorist had crashed into a lamp post (the reason is unimportant, the outcome is) the police checked the car and found all ok.
The insurance refused to pay out for the car or post. The reason Ė the tyres fitted to the car were of a lower speed rating than specified by the manufacturer, S instead of T. The police said the car was ok because the speed limit in this country was 70 mph and as the tyres were capable of 112 mph which is well above the speed limit they did not have a problem.
Moral of the story, by all means experiment with tyres, pressures, sizes etc but donít do it on the public highways and most of all don't have a guess at what you think they should be. Do it on tracks or private land. It was only a post and car but if a person had been killed what then? If an insurance company reaches the same conclusion re pressures as it did about tyre specs and will not pay, can you afford the compensation?
A gloomy picture I know but we do not live in fantasy land.
