Yes from experience. I purchased my NSX with 2,997 miles on the odometer. I immediately put in up on the lift and carefully inspected the bottom portion of the paint. It was perfect. Totally new. I then installed larger wheels and tires. Within 5000 thje paint was trashed. My front tires did quite a bit of damage but the road rash from the rears is insane. The rear fender is even chipped (behind the wheels). So even if I repaint the lower valiance it still will look like shit. I now have 13,000 miles and am definitely down grading the tire size.
By the way, I never drive on gravel, and never drive right after winter (when the road is sandy).
For 285 I believe you need a 10" rim. The rear doesn't look like it would be a problem with the stock 255's and my concern is for the front.
Could 1" really make that much of a difference for chips and etc I had 225's in the front with the 16" rims and now with 215"s and spacers it looks like the tire is about in the same area just the rim is pushed out more.
