I would like to find a tire that will give me long tire life and a quiet ride. I had noisy tires on the LS400 when I bought it so I gave them away and got a set of Nokian I3's that had a tread pattern that looked like they'd be a quiet tire. When I put them on, they were a lot better than the ones I took off, but after almost 20,000 miles, they sound like all the wheel bearings are bad, rotated them and more noisy on the back now but quieter on the front. What tire do I need to find that will get long tire life and still be quiet, I like the Michelin Hydro edge, but don't want to spring for that kind of money and wind up with a lot of noise, any suggestions.
