Those are the stock 7 series tire sizes, 4% greater diameter than the 650 stock diameter. So you will see 57.7mph when you are actually doing 60mph and the car will accelerate a bit slower compared to stock..

It's not a huge deal. If it was me I would drive on these tires until they wear out then buy the proper size tire when ordering replacements.
