Two concerns: Tire height and tire width. *Tire Width:* RBW says that the P45 Longboard fits tires up to 45m wide. *Tire Height:* You have to think about the *height* of the tire and being able to have enough clearance to sandwich the fender and brake arms between the top of the tire and bottom of the fork crown, and will there be enough clearance for the brake arms to move without them smushing down on the fender. Now, running a 35 tire should be able to get you more space vertically between the top of the tire and the bottom of fork crown, if a 40 doesn't work. So you could mount the fender further away from the brake arms if more space is needed so they do not contact the fender. That is the only benefit I can think of to having a narrower tire. Other than a narrower tire looks cool. For instance, both my 52 Sam and 55 Bleriot have their P45 Longboard fenders mounted as high as they will go under the fork crowns in order to accommodate my 650b x 42mm Marathons (Sam) and 650bx42mm Hetre tires (on Bleriot) with my Tektro R559 brake calipers on both bikes. I have about 1.5 mm of space between the bottom of Tektro brake arm and the fender on the Sam with marathon. The space grows as the brakes are applied. It is tight, but works great. Brakes do not touch fenders, and their is plenty of clearance for the tires. About 3mm of clearance between the Bleriot Tektro R559 brakes and the fender with Hetres. Plenty-o-space. (BTW, the Marathons are called 42mm and the Hetres are called 42mm width tires by their manufacturers, but both measure 40.5mm width on synergy rims at 55 psi).
