Your current tyres will be 215/45/17. I think people have tried this size (225/45/17) on the Clio. Only issue is rubbing if your car is lowered. I'd imagine only on full lock though?
As for the A048s. They are meant to be awesome. Mark ran these and R888s on his old Cup and said the Yokos were much better. Lasted longer and gave more grip IIRC.
not used them on my clio but have used them in the past. I prefer these to 888's, but the price premium on a new tyre over the 888's isnt justifiable (or rather i cant afford it).
but a very good tyre, that produces insane levels of grip.
