Fronts will have a smaller diameter/circumference than standard (by about 2% smaller) - closer size would be 235/40r19 (1.7% bigger)
Rears will have a smaller diameter/circumference than standard (by about 3% smaller) - closer size would be 265/35r19 (1% bigger).
Using the smaller sizes will make your speedo read even more above your actual speed - the larger size will bring it closer to true speed.
Can't comment on the wheels as I've never bought/used replicas/copies.
