Time for new tyres
I have just taken off a set of mixed Michelin Primacy (front) and Conti Sport contact 3 (were front, but served on the rear for two years) Both very good and have worn well. The Primacys have done 8000 miles on the front and have 3.5-4mm left. The Contis did 4000 on the front and then 8000 on the back and have 3mmish left. Both tyres were Predictable and grippy in cornering and braking both wet and dry at the front and the Contis have done a matching good job out back..
Just put on a set of Dunlop Sport Maxx RT. First decent drive today, maybe 150 miles. They are very quiet and offer good grip after initially petrifying 2 miles as I scrubbed off the surface layer. That was interesting!
All very capable, virtually nothing in it. The Dunlops are very much quieter than the Contis and slightly quieter than the Primacys.
In terms of absolute performance, I think I'd just edge the Primacys in front, but I haven't really had need of extreme grip on the Dunlops yet.
You be honest, there isn't a lot in it with general purpose, everyday tyres.
Bit of advice I heard from a good garage lately.
Avoid the V shaped treads on Alfas, they appear to increase noise greatly and also appear to wear measurably more unevenly compared to regular band and block design tyres on the same cars.
