    So if I put 225 tyres on my cup alloys there should be no issues

    I have 225 AD08R's on my standard alloys and they work fine. Some would say that your tyre choice is not ideal for track however.

    Yeah i suppose it would be better if i put 245 on them. But the difference between 225 and 235 is nothing. Price difference is 60 pounds for two. Done plenty of track days no issues.

    245s are too wide for stock sized rims, you need a 8.5 or a 9 for them to sit properly

    I run a 235 on my rear OZ's which are only a 8j and even they are a touch too wide but seeing as they are just road wheels I'm happy to have the softer ride that they give

    225 for semyslick and 235 for road tyres on that wheel size.
    225 road tires are stretched on 8" wide rims let alone woder, but semyslick are wider usually then specified and work fine with woder rims.
