I put 4 new 175/70 R13 Toyo tyres on my GT6 about a month ago - seem to grip the road nicely and are quieter than the Avon front, Hankook rear combination I was running. Much lighter steering too! Bought via Blackcircles. Was going to go for the Falken option (often run my moderns on Falkens), but couldn't justify the extra £12-£14 per corner for the 3000, mainly dry miles I do each year.
