Defective tire
"I changed my old Maxxis Minion DHR for this more rolling Crossmark 2. Since then, I've had nothing but problems with air leaks around the rim. So much so, that at first I blamed the rim for a leak in the spokes (tubeless). But after refitting the old tire, I saw that it was the tire itself that was causing the problem. And I even noticed leaks on the sidewall of the tire on both sides."
