Shite Tyres, cheap for a reason.
If you report they are good then you are shite too
I thought the a048 were good, but the cups were another step up from them.
Buy cheap buy twice, but I suppose being a few seconds a lap slower is not the end of the world, and it's the fun that counts. But all your fancy engine work and mapping is pointless if you are scrimping on the only thing that has contact with the Tarmac.
