Hello guys! I wanted to raise the summer tires today. I needed them on Alutec-Alus. I was just stupid because the original key from Mazda doesn’t fit in the holes. The nuts fit just like that into the holes, but for the key there is no room anymore. The key is a 21er (measured). The nuts have measured 10.5 mm inside diameter, that should be M12. And for M12 usually comes a 19er key, so they are probably not standard nuts. I understand that correctly, I need now 19s or 20s nut and a matching key or a nut with a maximum of 22 mm outer diameter, because the holes in the rims are so big, but I have a few questions. Do you have to pull the whole with a torque key, or is a normal (cross) key sufficient? Would be nice if someone would answer briefly. P.S. And still something on the edge: the winter tires have a stamp (039D) where D is a triangle/arrow. hme that it means week 3 year 99, and so the tires belong on the garbage, right?
