There are Vredestein Quatrac available for my Jazz - C economy, B rain, 70Db
or Bridgestone Weather Control - C economy, A rain, 71Db
vs the standard Yokohama BluEarth - C economy, C rain, 68Db.
I'm leaning towards the Bridgestones when mine are due for replacement, but it may be some time.
In 5k miles my front tyres are down maybe 2mm, so I have maybe another 10k miles left on them. Rears are likely to last quite a bit longer, so even if I rotate them when the fronts are below 4mm it will be a while yet.
Prices seem to be around £500 for a full set.
