Before buying a set from Y1, def worth reading comcerning the issues with the impropperly machined centering hole.

Personally would search out a fairly clean original set of wheels & have them locally remachined/restored. The best candidates should have minimal brake dust damage. Brake dust damage is the major problem, not lightly curbed edges.
On 2nd Gens, bought & installed well over a dozen sets of 255 60R15's on 15x8 snowflakes & Turbo wheels back in the early to late 80's. Was my experience there's a bigger rubbing issue at the stock wheel lip on a heavily equipped car at the rear wheel wells than there is in the front wheel area. My experience is 245's & 235's don't have enough section width to protect the near 9" wide 15x8 alum wheels. The same problem existed when factory equipped the cars with 225/70's. in the day, Goodyear made three different Eagle 255 60's, with the NCT having a near 3/4" narrower section width, but it was stickier than both the slightly wider Eagle GT & the entry line ST. Mention that, as every few weeks one PY board "contributor" loves to throw out absolutes of tire height /size. Always get a chuckle out of his statements, as different tire lines are often made with different section widths & overall height in the exact same listed size. Best to mount 'em and ck them before making such broad statements.
