I have 17" "V" series Weld wheels on my '70 Cuda with 28 x 6 x 17 M/T Sportsman tyres and all works fine. But the only thing with these wheels are the thin spokes especially because of being 17" so other than being real cautious on rough roads or cornering fast it's fine.
My Cuda is track only so the spoke size isnt much of a concern.
As for tires I usually run 26 or 27". Mickey, M&H and Hoosier all offer the sizes I like.
I just like the wider rim. Prefer the looks of the 15. I know on my wagon the wider rim really settled it down but it is a heavy pig(4000lb) and my Cuda is 3200-3300 race ready.
