Sadly no, autocrosser reviews of tires are the best way to judge before buying, but you can imagine how subjective it is. Almost any performance tire, especially quality ones will have a stiffer sidewall than all seasons. Bridgestone has been known to be stiffer than average and makes a great tire. Either way, the difference isnt like a set of coilovers, its a small change.
Also, sticking a wider tire on a wheel with a given sidewall height will increase tire roll, not reduce it. Those euro kids and their “stretch” look were onto something before they took it too far…
