Tyres good tread but dry cracking. Replace to pass MOT?
Just bought a second hand set of wheels with Michelin PS4s on. Replaced the rears as the tre,ad depth was just about legal (I live in the UK). The fronts have 4mm tread, but has dry cracking on the side wall. I have a MOT coming up (vehicle road worthy inspection/test) and I am wondering if these will pass, or should I get them replaced as well? I have done my research however it seems like there is no consensus and very different case by case so decided to ask you guys here.
