Well we all know the 555r's are summer tire mainly but they did pretty good i felt the rear getting squirrelly around 65+ so i stayed at 50-55. There was tons of sitting water on the highway and flooding in numerous spots. The highways here definitely need work. Now for the worst part SD drivers OMG! so im doing 50-55 and these people are cruising by at 75. Too dumb to drive to the weather? its also cali law if your wipers are on your lights are supposed to be on and that definitely wasnt happening. from 32nd street naval station to Santee i counted 8 accident total on both sides of the highway 2 cars upside down 2 cars facing oncoming traffic and 4 against the cement median. i think that would be enough for me to use common sense to slow down or maybe the 20+ cop cars staggered through out the highway with their lights on and the fire trucks and ambulances but no. its supposed to rain for the next 2-3 days i bet near 1000 accident have occurred in the state of California. Survival of the fittest and smartest i guess
