Yeah I know not every tyre place has every tyre in stock or anything, but for the Michelin website to not even list them and my local tyre place rang Michelin UK and they said no they don't make them... maybe they just don't make them for the UK market but seems pretty weird.
Anyway, seems like going to 225 is going to be fine anyway judging by what everyone else here is saying. I'll get 4 ordered tomorrow

Thanks!
