I recently got a 2018 Mazda 3 Touring and put the winter tires from my old 3 on them today. They're 16x7 205/60/16 ET50. They never caused any problems with the old car but today I noticed a knocking sound from the right rear wheel when hitting larger bumps. Could this be a fitment issue or something with the tire? I know Mazda3 Sports come with 6.5 in width wheels but I didn't think the difference would be an issue. Any help would be greatly appreciated. Thanks!
