Need diameter for PP3 tires

I did some more riding on my new PP3's and noticed the front felt a little vague as compared to when I had the Dunlop Q3's mounted. It wasn't a grip issue, I just felt the feedback wasn't what it should have been.

If the front tire is taller than the Q3, or the rear tire is shorter, this would change the geometry by increasing rake/trail, and would explain the vague feel.

I was able to get the exact dimensions of the Q3's but cannot find the Michelin tire spec chart anywhere. Based on some measurements I took, it does seem that the rear PP3 is noticeably shorter than the Q3, which would definitely explain what I was feeling.

I cranked up the preload on the rear shock (Ohlins, threaded) by about one full turn which seems to have given me another 4 mm in static sag.

I'm gonna try the bike again and see if the front end doesn't improve. As things are I would never push the bike as I would with Q3s. However the PP3 would probably be a better choice for the majority of street riders.

Anyone got a lead on where I can get the actual Michelin tire measurements?

Thx
