I ordered a set up of Yokohama Prada Spec-2 225/35/19 for my Tl-S and a sell rep called me back and told me that it is a serious load bearing issue and that he doesen't recommend it. I know others have put 225/35/19 on their car. Did any of you guys have this issue???

 

The factory Pilot MXM4s 215/50/17s have an XL load rating, and are rated for 1433lbs. The 225/35/19 Spec 2 has no XL load rating, and are rated for 1235 lbs. The TL-S weighs 3558 lbs, with 63% of that hanging over the nose. That's 1120 lbs on each of the front tires. You are right up against the limits, and you haven't considered the increased loading (through better cornering) of that shorter sidewall tire, beyond what the factory anticipated in the design of the car.
I know there are people that have done it, but I wouldn't- not particularly if you enjoy "spirited" driving.
