Factory OE tyres can be homologated and marked specifically, see our articles.
Also, tyres may be out of production, so you should pay attention to the next generation of tyres.
And, of course, for cars of the premium class and less (compact, middle...), the choice of tyres from
the original equipment is less important, than for owners of sports cars, for which OE tyres were chosen
by the manufacturer much more carefully.
