u/Accomplished-Gap-748

I've installed two GP 5000 (S TR, 30 mm) and did 300 km with them yesterday. I had two big flats and needed to use plugs. The first one, on the front tire (at 200 km), required one plug. But the second flat, on the rear (at 250 km), was so large that I needed two plugs, and I inflated the tire less than usual to prevent the plugs from coming out.

For clarification, the tires were correctly inflated (3.7–4 bars), and the road wasn't great but not that bad either.

Do you think this is normal, or do they have a problem? I bought them at a Giant store and I'll call them, but I wanted other opinions
