Again I'm flabbergasted at this advice:doh::doh:
Anyone who has experienced an actual blow-out at motorway speeds will tell you what a terrifiying experience it is to bring a car to a stop with a blown front tyre. Not near as bad with a blown rear one.
It goes back to what I was saying about a spin, it requires differential grip between the front wheels to initiate a rotational moment under braking. If you get a front wheel blow out and do a panic stomp on the brakes you will spin. Blow out a rear and you can much more easily bring the car to a stop.
I must do a bit more research to see what is driving this advice. I honestly believe this is a hangover from the old cross ply/RWD days and is totally at odds with the type of cars prevalent today.
BTW I shouldn't be surprised that a tyre fitting company would give wrong advice. I can't count how many times I've been told (and gotten into a subsequent argument) that there is no need to balance rear wheels by tyre shops. This is total boll*x too, you need to balance rear tyres for the exact same reason as the front, its just imbalance isn't as immediately apparent but it'll f*ck up your bearings, handling and noise characteristics just as quick on the back as the front.
