New rear tyres (Kumho) - now odd handling

Tyres are designed to work with a balance of construction and compound, not primarily compound which is a common mistake people make. Hence a tyre running backwards may move the construction (tread/sidewall) around more and overheat even at sensible speeds, even if it has a strong/firm compound....not good!

Cheers

Simon,

Interesting, thanks. I hadn't considered the construction angle; I had always assumed that the directionality was purely a function of the tread pattern.

I've just had 4x Khumo Ecstar sport fitted all round and on the way home coming up to a roundabout at 70mph the brake pedal went straight to the floor ?
Never found out why and its never happened since.?

As the wheels are the main retainers of the brake discs I wonder if they knocked the disc out of alignment pushing the pads back hence needing more than one press on the pedal to get them back into place. That is assuming you didn't brake between the fitters and the dual Carriageway.

well thats the weird thing ? I must have braked several times in a 15 mile journey but none of them with quite the urgency of the last time as I had been stuck in a traffic jam for the preceeding 10 miles .

I just cannot begin to describe the terror that you feel approaching a roundabout at 70 to find the pedal goes all the way to the floor ! gulp
