They aren’t stretched from a performance perspective, only from a look perspective (again, mainly due to the profile around the rim protector to extend the rubber in that area beyond the rim lip), depends on whether you place looks above performance. Modern low profile tyres don’t have the balloon look of older high profile tyres. With the rim on the narrow end of the tyre manufacturer spec (7.5” for a 225/40-18) the contact patch will be narrower than on a wider rim, giving the tyre the performance of a narrower tyre on the same rim width. Michelin have engineered the tyre to fit on a 7.5” to 9.0” wide wheel, 8.0 or 8.5” wheels are going to give a more optimum contact patch than 7.5” or 9.0” wheels.
