German rubber - that's what she said - is the only non chinese thing on my bikes. Continental knows a thing or 2 about tyre compounds. They've been showing consistently that they make better compound (especially factoring in reliability / lifespan in the mix, rather than pure performance).
I have experienced what bad tyres & good tyres do to the same bike, and so, GP5000 for me. I dont ride enough to care about how much they cost, and i dont commute to work anymore.
I'm in Europe, so i usually pay 40-45 eur per tyre.
