Yeah. Both my RS3's and Conti DW's are 275/35 on 18x10. When I compare the unmounted 265/645's to the mounted DW's (just lining them up with each other on the floor), the width looks identical. But we'll see what happens when they're mounted. If they do fit, and the sizing is consistent between dry+wet, that makes me think 285/645 might be a tad wide for 10's, but I have no idea. I guess the smart thing to do would be to call Hoosier and ask
