SO. I've had my 2018 Outback 2.5 Limited for a few weeks now. Love it. However, after about 300 miles, I didn't find that the noise improvements for 2018 made up for the road noise from the stock tires. So I put Michelin Premier A/Ss on. I've now got about 800 miles on those, and I am still hearing plenty of road noise--from 20-80 mph. I called Michelin and was VERY impressed with their 30 day satisfaction guarantee. They'll pay for non-Michelin tires if I want them. Tire Rack tells me the Pirelli Cinturato P7s will be quieter. Even if it's no cost to me, should I bother? If didn't really hear an improvement when I went from stock to Premier A/S, am I really going to notice the switch from Premier A/S to Pirelli Cinturato P7? Other people's experience? Other thoughts? Thanks!
