Supply chain issues are not geographical. There are raw material shortages all over the place.
But yeah, GP5000 TR are out of stock at the distributor so unless there's a shop with a pair they haven't sold in a couple of months, you won't find any for a few weeks yet.
Has anyone seen some GP5K S TR unicorn tyres in stock anywhere? I thought they were all made in Europe, so don't understand the crap stock scenario.
