The ride is good...a little firmer, but not objectionable. The handling, though, is remarkably better...the thing turns like a dream now and it's like it's on rails on the freeway. Totally stable. I'm having a slight shimmy problem above 65 mph and am taking it in for high speed balancing, but other than that, no probs!
Nice wheels. I get my Pilot in Oct. and am getting new tires and wheels. I have picked out the tire Diamaris, like you have. Do you love them? They are supposed to be a fantastic tire. I'm probably going to get a 19inch wheel.
The Diamaris are frickin' amazing... The handling, the ride, unbelievable. You won't believe the difference. Think twice about 19 inch, though. I got 18" and it's harsher...just on the boarderline. You might find the 19 inch just to hard.
