2001 BMW X5 E53...RealOEM.com, Bimmerworld.com both show the OEM wheel bolt size to be M14x1.5x19mm, PN#36136756298, but looking up on FCP Euro, ecstuning.com, Autozone, Dorman all say it's a M12x1.25 bolt. Short of removing a bolt to measure/compare, which size is accurate? My X5 has the std. type 57 wheels. And will I need a thin-wall socket (of which size. again) to torque down a bolt on these wheels. I have many sockets, but no thin-walls.
