Just got home from Wales. The V12s seem very good, I would say marginally better than the Conti's! There were a couple of problems though. On the way there I thought the tyres weren't particularly great, as the car felt strange at higher speeds, as if the front was lifting up and I was loosing grip! So when I got to the camp site I was staying at I checked the tyre pressures (something I forgot to do before I left). The front two tyres were 7.5 PSI over inflated, the offside rear was 5 PSI over inflated and the nearside rear was 5 PSI underinflated! As soon as I altered the pressures to what they should have been the car handled much better.
The next thing was the amount of slow moving traffic on the way home! I was getting really annoyed! I overtook a few cars in a line of 4, but as soon as we got around a few other bends there was a huge line of caravans, vans and other cars. So there was just no point in even trying! I wish I could have had the roads closed!
The third thing was that my missus is a bit of a nervous passenger and keeps telling me to slow down every 10 minutes!
Dispite all of this the tyres do seem good. Especially considering how much they cost!
