The MGOC forum has had a good report on the new TR1 tyres on 16" wheels , but the consensus is that the Falken Zeix ZE 310 is a better tyre, certainly more popular with club members, and recommended by VHS who should know, as they were the original Rover/MG Rover engineers, (Andy Kitson and Alan Phillips), who were responsible for setting up the MGF and TF, (and other Rover and MG cars), and were also responsible for completing all tyre testing.,,,,good enough for me , when my T1R's finally give out, that's what I will be doing.
