I am running the archilles atr sport in 245/35/19 after I went through a set of Z1s in a tad over 20,000km (this was down to the point of bald and actually showing the belt in some parts). The archilles were only $150 each and with a 400 treadwear rating I thought brilliant!! I will get much more use out of them, I am about a mm or 2 from the treadwear indicators and I have done 21,000km so far plus the traction they give is actually pretty decent. I would most likely use these again even though people have said they have weak sidewalls if they pop that's a manufacturer defect and then get a new set under warranty :-) might not ever have to buy new tyres again lol
