On my Insight's RE-92s, the ratings are:
- Treadwear- 260
- Traction- A
- Temperature- B
They now have over 16,000 miles on them. The fronts tend to wear on the outside a little - but this may be an Insight quirk, not the tire. I do corner at elevated speeds.
At 50-55 psi, they ride stiff and make some noise. The Insight has little sound-deadening, so that makes it more pronounced.
At lower pressures, the ride improves slightly, and you take a hit on the MPG's.
