Its allready been said "dont panick Mr mannering"
Michelin have thrown in their "get out of jail free" card on this one.
The tyre industry is hell bent on promoting winter tyres to boost a
difficult market place. There is a lot of disinformation (my personal belief)
being published by leading tyre manufacturers to change drivers buying pattern.
In many european countries it is law to change onto "winter" tyres at a given
time, and change back to standard tyres, again at a set time.
This of course means many legally treaded tyres are left with tyre distributors
to dispose off !! Guess which country imports the most "part worn tyres", yes,
thats right, good old Britain. And who has to deal with the scrap tyres ------
To bring this subject into focus, the critical temperature for concidering a tyre
change is aprox. 7^. However,on wet roads, braking distances are still greater
on winter tyres at this temperature.
At 5^ "summer" tyres on the same wet road take longer to stop than a winter tyre.
On snowy roads from 30mph the summer tyre takes 9 meters more road to stop on.
On icy roads from 20mph the summer tyre takes 11 meters more road to stop on.
Having tried several winter tyres on various BMW's I can honestly say that the only reason
I would concider changing would be long term snow ie; several weeks.
If any one is going abroad with their car, I have a set of 17" winter snow tyres for sale !!
Sorry if this has rambled on, but if any one wants more info on winter tyres , please email
me at Jimp@rhc.co.uk
and I will try to help.
Happy new year to all at LEC
