Replaced 4y old goodyear ultragrip performace with these. Car is RWD BMW 325D.
First impession is really good. Tyres are extra extra quiet in all conditions ( dry, wet, snow). Noticed slight increase in fuel consumption.
last weekend was extra snowy, roads covered with snow, on my trip with alot steep hilclims on the road. I passed few stuck and strugglig cars and came to my destination with pleasent surprise...
