Avon Trailrider is the only tyre that I've changed like for like on my GSA in nearly 40,000kms. I've had PR4, Scorpion Trail 2 and TKC-70, in my opinion the Avon is a more complete tyre than any of the tyres I've tried on the bike.
The best rear tyre mileage I ever had from a road tyre was the Maxxis SuperMax and very good handling. There was minimal squaring off (better than Continentals) and the shoulders went down at a similar rate. Unfortunately, SuperMax is not available for 19" front and their big trail offering is really not up to much.
I suspect he is only interested in tyres that will fit his bike. I have got Pirelli P7's on my Mondeo
My favourite road tyres on my GS is the Bridgestone T30 Evo or Dunlop Roadsmart. I don't go off road
If you lo0ok back at previous tyre threads you will soon realize everyone thinks their tyres are best and nobody has tried all of the offerings
How did the Scorpion Trail 2's do in comparison to the others? Thinking of fitting these to my KTM 1290SA instead of Conti Trail Attacks.
