Elise S2 111S/R Winter wheel sizes

[S2111S]

Hi,

New here to posting but have been a long term reader of Elise posts, particularly the 111S v 111R debate and the daily driver opinions. All very useful - thanks.

I'm currently confused about wheel sizes when using winter tyres. The 2001 onwards Service Manual states:

Standard 5.5j x 16 with 175/55/R16
7.5j x 17 with 225/45/R17

Winter 5.5j x 15 with 185/55/R15
7j x 16 with 205/R16

However, the Federal Elise, albeit 2005 onwards Toyota, keeps the wheel J and diameter the same at 6.5j x 16 and 7.5j x 17, summer and winter.

So, not having seen wheel sizes mentioned in any of the winter tyre threads my question is why are the UK winter wheels reduced and the US winter wheels unchanged and is it ok to keep with the standard UK wheel sizes when changing to winter tyres?

Any responses greatly appreciated,

Simon

Thanks very much, Drac. Snowsport now replaced by SottoZero 3 on the rear and Snow Control 3 on the front.

Worth knowing Sheetmaself but I just can't bring myself to try it - getting old I guess.
