ISO demands 4mm per side to be legal to sell.
Personally, I rode for years with 2mm per side and no issues.

Well I bit the bullet and got myself a set of zipp 202 tubulars with Vittoria 25mm tubs and it fits, at a guess I have about 3mm each side which is about the same as my dura ace with 23mm schwalbe one pro tyres as they actually measured about 24.8mm with a vernier

2016 super six SM with Michelin Power comps that blow up to 27.5mm on 19mm internal kinlin rims - I've got roughly 1.5mm between the stay and the tyre with no obvious signs of rubbing..

I have a 2015 Hi-Mod. I used a micrometer to measure the spread at the tire location - reads 30.8 mm. I am running stock Ksyrium Elite S with 25c tires (25 mm actual) and naturally no issues. I threw my wife's HED Ardennes LT, which is a 21 in/25 out, with a 25c Michelin Pro 4 (26.8 mm actual), and it was close, (2 mm eachside) but probably OK, as long as you had no accidents.

It's worth noting that the lateral deflection of the wheel under force will be in a line from the point of contact on the ground through the hub(and to the top of the wheel). Brake rub happens because it is somewhat close to the top of the wheel. Where the chainstays meet the BB is about as far from that as you can get on the wheel, meaning a decent wheel shouldn't flex much there.

2015 Evo, 25mm conti will not work with Mavic 40mm clincher, or Campy Eurus G3

You just resurrected a one year old topic. Not a problem. Just letting you know.

Some good threads need occasional resurrection!

Further to the topic, I put a 25c Continental Grand Prix TT on American Classic 420 Aero3, which has a 19mm internal spread. Caliper on the tire is 29mm. Gives 1.5 - 2.5mm clearance (holy cow, those tires were a b*tch to mount).

Rubs under torque at the chainstay. Back to a 23 there.

I have a Cannondale super six {no-himode}.
No matter what I do, I can’t get the wheel aligned - so I have like 1,5 mm of spacing on the no drive side, and 3 on the drive side.
25mm tires.

Sounds like your rear drop outs are misaligned, not and uncommon occurrence with Evos
