Both sets of tires are from different reputable manufactures but the details are the same. ie Clinchers folding etc.
I recently changed my tires on a road bike, the clearance on top section of the rear seat stay was always very small with OEM wheels and tires. I would guess about 3-4mm.
I got new tires with the same specs from different manufacture and at the recommended psi the clearance from the top of the seat stay is about 1mm and I never noticed it while riding about 3k miles. But once i took it apart i noticed that the tire has been rubbing on the seat stay. I can see the paint has rubbed of slightly.
Update: picture below - hard to see because of brakes but the top of the seatstay is marked with red line and the top of the tire is marked with green line.
Wheels are true!
