I remembered something that I wanted to post about but completely forgot. The last set of tyres I had on the 3.2 were Hankook's Optimo 4S. An all seasons tyre, that to be fair was very grippy, worked especially well in the wet and lasted about 18k. Usually I change tyres at or just below 3mm. But work and other issues prevented me from changing them when they got down to 3mm.
One wet Friday,few weeks ago I was travelling up the A1M and decided to take the A57 across to the M1 as the sat nav identified an accident up ahead. Going past one of the roundabouts, I remember being in the fast lane, approaching the roundabout, perhaps a tiny bit faster than I normally do/should do. As I hit the roundabout, I lost all rear end grip. The next thing I know the back was sliding out and I was applying counter lock to try and gain control of the car. It felt like an eternity before I got the car back in line and managed to drive on in one piece. Thankfully no one was next to me in the outer lane or else I would have hit them.
Got home and checked the tyres the next day. 2.6mm depth pretty much across the tyre. Reasonably even wear. No bulges/bald patches. So what caused the loss of control? Could it have been a patch of oil? Or is the advice to change tyres at 3mm the correct advice?
More so, if 3mm is the depth to change at, then these so called part worns are pretty useless?
Suspension has been poly'd and set up at WIM about 12 months ago.
So what tyre depth do you change your tyres at? I am certainly going to stick with 3mm.
