    RS tires sizes and options

    I have a 1972 that was converted to "RS" with 15x7 fronts and 15x8 rear.

    I want period look tires but would entertain a wider tire on back.

    Avon looks to be period. Anyother options?

    Stock size should be 185 front 215 rear.

    Anybody stuff a 225 on the back?

    225’s fit easily on the back, but finding 15’s in a 225 is tough. Pirelli recently released cn36’s to fit 15’s

    Pirelli CN36 are available in both of the factory sizes, 185/70 and 215/60.

    Ed recommends Eagle GT for a lower cost option. That would use a 195/65 at the front and stay with the 215/60 rear.
    You really don't need more tire.
    I think the P6000 comes in the original sizing too, a little less than the CN36

    P6000 doesn't look period, and the Goodyear is NLA in 215/60-15 now. For period looks, it's either the CN36 or Avon. CN36 is what RS's came with from the factory.

    For lower cost without dropping to a "touring" tire, Sumitomo has the 195/65 and 215/60 sizes in the H-rated HTR A/S PO2. But it doesn't look period either.

    The Michelin XWX are being remade again. The first series had issues on side wall belting count, but now supposedly all good.

    Coker in the USA and Longfellow Tires in England sell them.
