Was is a Bic pen?Wow! Sorry to hear that. Freaky things find their way into tires. I remember once my wife got a ball point pen in her tire! You'd think a 3000 lb car would crush a plastic pen, but no. Anyway, I think overall, Michelin tires are among the best you can buy. Granted, Primacy aren't a really good off road tires, but they should last a long time. Good thing you had your compressor.
