ContiClassicAttack actual dimensions

I am building a cafe racer with a combination fork brace/fender mount/caliper hanger. I need to know tire dimensions/clearances to complete this part of the project, but don't want to actually purchase the tires until the project is closer to completion, so the tires are fresh. (I've been "working" on this bike for nigh on 30 years, and it might be a couple more years before it's actually ready for tires.) Since no tire company other than Avon seems to publish actual measurements of their tires, I was hoping someone here could take a couple of measurements for me. The bike has an 18 x 2.15 Sun rim on the front. At this point, I am considering the 90/90 R 18 ContiClassicAttack and the Michelin 100/90-18 Pilot Activ. If anyone out there has either of these tires and can measure the actual overall diameter and width, I would greatly appreciate it. Thanks.

Why would you build a bike with tire clearance so tight that you are committed to one specific brand of tire? If you plan for it to be functional, that tire may not be available when it comes time to replace them. Or, if this is not a functional build (not really something this crowd has much appreciation for) buy the tire you like the look of, and build the bike around it! It won’t matter because the tires never wear out in a Pipeburn build....
