Yeah, I kinda figured that the rear 30 series are gonna look like black rubber bands on silver wheels compared to the 40 series up front.

But the 285/35/19 are pretty rare. Only the Michelin PS2 at Tire Rack, not a tire I want.

And at 26.9" vs 26.0" stock, that introduces a 3.5% (slower) speed error on a larger diameter that creates effectively taller gearing.

The 275/30/19 goes the opposite direction at 25.6" vs 26.0 stock for a smaller 1.5% (faster) speed error on a smaller diameter that creates effectively shorter gearing. I like that better directionally.

My only other option up front was a Pilot SS in 245/35/18. But that tire is 0.8" wider than the 225/40/18. I was worried about rubbing in tight turns.

My biggest worry isn't the weird difference in looks. I'm wondering just how much the ride will suffer and if I'll get the additional rear traction I want. I'm pretty certain it'll do what I want on smooth pavement. Not so sure about less than perfect surfaces. Just hope I'm not replacing bent wheels.
