Thank Ryan, good to get a view. There’s an inference in what you say that sport tyres are probably at the softer end of the spectrum anyway, and Metzellers may be some of the softest too. I heard a similar view (Dave Moss videos I think) that Dunlops tend to be a stiff carcass and full of bumpy feedback, and Metzellers soft and a bit calmer. Given I’m on sports Metzellers already, this may be a nod to having nowhere left to go re tyres, and the answer is more valving work.
Framing the issue in terms of car tyres, I’m looking for that night / day difference you get from ditching Run Flats for a normal tyre… when all that harshness just disappears. But I suspect I’m not going to see that level of improvement between bike tyres. Ta.
