Hmmm, I just paid twice that for 245 35R19. OTOH, do you really trust Walmart to mount and balance your low profile tires properly? These are mounted on 19x8.5 wheels.
I have 245 40R19 winter tires on my 5 hole 19x8 OEM wheels. Combined with the "read high" bias on the speedo, they make my speedo read correctly. Please beware that a little tire stretch is good for handling. I have not tried PS A/S 3+ in this size, but I can say that Nokian R3 tires in this size on dry pavement are not good. They are however, amazing on snow and ice but of course driving snow and ice is all about traction rather than handling, at least at my skill level.
One more thing to note: Michelin PS A/S 3+ 245 35R19 tires have about 30-35mm more tread than the Pirelli Cinturato P7 RFT in 225 40R19.
