Have to switch them around to even up the wear so they all need replacing at the same time because Renault imports Clio Sports cars into this country (Australia), but Michelin doesn't consider there's a big enough market for the tyre it uses, so they don't import them, so you can't buy identical replacements when they get punctured (like one of mine did) or they wear out.
And with stuff like traction control and ESP on it looking for even small differences in wheel rotational speeds I'm a bit worried that even identical sized tyres from other manufactures might be sufficiently different in rolling diameter to cause problems.
