Uniroyal RainExpert 165/55 R15 Lancia 18,000 miles July 26, 2015
Had these on a Lancia Delta 1.6 16V.
Dry grip is exceptional in the price range. They have a softer side wall, so inflated them to 2.8 Bar - no problems there. Wet grip is more than phenomenal!!
I even used them on a trackday with the delta, pushing them to the limit, no problems whatsoever. They just grip and squeal, you can hear when they're about to let go.

The price you pay for this is wear: they wear out faster than other tires, however you can get them for a lot less money.

Comfort and noiselevels are good.

Highly recommended, very safe!
