It's highly recommended to have quite a bit of room between fenders and tires. Trying to squeeze the biggest tire you can physically cram under a fender can be dangerous. It becomes too easy for a piece of road debris to get caught between the tire and the fender. I've gone over the bars from an accordioned front fender before - piece of branch got caught and pulled into the fender. It's scary and can happen terrifyingly fast. I like 1.5 to 2 cm of clearance ideally. Rivendell suggests up to a 38 with fenders, and 43 without. If you want bigger, maybe a Roadini is not the right bike?
