I've never run any 16x7 wheels on this car, my winter/rally working wheels are 15x7s with a 195/60-15 on them.
Actually, the 205/50 Neo Gens appear to be pulled in (the total opposite of stretch) at the bead/side wall, even on 8" wide wheels, such is the section width (and maybe tread width as well?) of those Nittos.
My local installers, (except the one local tuner shop who did the installation) ALL balked, or just flat out refused to put any 205 on an 8" wide wheel, 45 OR 50 series.
But most others on here have not had that problem at all, in their locales.
But as stated above, there is no actual functional problem with putting a 205/45 on an 8" wide wheel, save for less road cushioning, and potentially a greater chance of wheel rash from curb scrapes.
