Hello Malcolm, it’s newell here, I have the Tkc 70 tires on my old bmw gs . Always used to runMetzler tires until I noticed they are now made in China!( isn’t everything? ) nice chunky, but smooth tread. Initially the front tire looked to tb about 2/3 depth of the rear, but I haven’t noticed any issues since I bought them. The last set of conti/attack street tires were very good as well and they are still made in Germany. Hope that helps,Malcolm. Thanks for shipping the rack and bags to me!
