Using the 33 mm tan sidewall on the SES 4.5 with 15mm inner which measures 35 mm according to the box diagram.
Nice grip on corners at speed.
Comfortable on lousy asphalt.
Feels solid on long downhills.
Had to take off my fenders but that's ok
I have 32,879.0 km entirely on ENVE tires (one 31mm, two or three 29mm, and now 33mm) without any roadside repairs.
I like these a lot.
