How about mounting on wheels: 8,5x20 and 10x20 - tires: 245/45 and 275/40? This combination may look more agressive, because 40 and 35 profil look a little bit funny to me, when there is no stance at all. I am not going to put any lower springs - this is total daily
There shouldn't be problem with poke etc, should there?
There is around 3% difference to what OEM tire sizes are.
