• Could it be that supple tyres stretch more and come up wider? Pretty sure Open Corsas come up a size big as well

    They do, my Grand Bois Hetres is 38mm at first, but after a couple of week it finally stretch to 42mm.

    Even Corsa SC 25mm come up to a staggering 29mm at 100psi (guy on here run it that high).

    GP 4000sii is inconsistent, a 25mm set on 13mm internal width is 26mm, on customer's bike with 13mm internal too; 28mm.
