I'm shopping for tires for my 2014 Kona Dew and want to go with the widest that will fit. My measurements of the frame tell me that the limiting factor is the overall inflated diameter of the tire. I know that ERTRO 42-622 will work and am comfortable that 45-622 will work as well; however I really like the Continental Top Contact II, which is available in 47-622; however I think that is getting close to my limiting factor. I figure I can go as high as 720mm overall before I start rubbing on the frame bridges or fork crown.

If anybody is using these Continental tires in 47-622 size (or any other tire in that same size), I'd really appreciate if you could take a quick measurement and let me know what the overall inflated diameter is. Also let me know what your inner rim width is.

Thanks much.

What tires, what size, and how much room do you have currently?

None. I'm building up new wheels for the bike. I did try a 42-622 from another bike and had about 10 mm of clearance to the fork crown.

I reached out to Conti customer service, and their reply was to try them ------ lol. They had no knowledge.

I had sent them an inquiry as well. Here's what they said:

Thanks for reaching out and for your interest in Continental Tires. We're sorry to confirm that exact tire diameters is not published information we have available to provide. Even with knowledge of the rim's inner width, there are still variables present that will potentially effect tire height and width such as pressure levels and a minor acceptable production variance. Regrettably the only way to be certain of tire clearance is a test-mounting. Local bike shops are often happy to accommodate a test-fit if the shop has the desired tire in stock and if you intend on making a purchase through the store. Please feel free to make use of the dealer locator feature for a list of Continental authorized dealers local to you. Dealer LocatorHighway Two | Highway Two

Yeah, probably their customer service people have no clue, but someone in the company does. I reckon it was too much trouble to at least try to answer my question. I realize that there are a number of variables that would affect diameter, but all I was asking for was a ballpark number. I thought of replying saying that Schwalbe, their competitor, was happy to provide me measurements (Yes they did - no fib), but decided it wasn't worth the time.

In any case, I decided to go with Panaracer Gravel King SKs in 43-622. I have always liked Panaracer tires and I know that these will fit fine. Thanks much for all the responses.
