Heavy Wear and Opinions on my Next Set

[CarbonZHP]

Ive been running Pirelli P Zeros for about 12k and the rears are already dead. Threads showing. I do run some camber but no more than my F06 has stock. Not even at the end of the stock camber arms. I realize these tires are soft and expected quick wear but they appear to show more camber wear than there actually is. They are 255/30/19. Ive already found some Toyo Proxes T1 Sport. 255/35/19. 4 rears for 400. 80% tread. My question, how different will the 35 be from the 30 and will it increase any fender rubbing? Thanks.

Also suspicious of the RTABs...
