purchased for a skilled Citroen C4. R16. 71 db in terms of noise is a bit noisy, but it's not a deal-breaker for me because the Citroen has no sound insulation at all, so according to European stickers (and I trust them more than the ratings of our auto publications) it's great in the wet and only gets an A for economy. There is obviously a lot of silica in the mix, which accounts for the noise and the smooth ride in the rain. I therefore don't anticipate very high mileage. Everything was as expected. entered the showers. submerged in a rut. At up to 110 mph in civilized traffic with no indication of aquaplaning. Overall, it's definitely a good investment. That is what any middle-class peasant needs. Not dissapointed thus far.
