Like i said i have had no issues whatsoever with them, and i lived in Washington state lol the wettest state in the US, i DD my car with 315's for a good 5 months until i bought the danger ranger and loved them. As long as you werent romping off the light in the rain you were good to go, these tires are pretty sticky considering that they are regular street radials. I got mine from americanmuscle.com cause they ship free, but i also messed up a rim bad and they were the only ones who were willing at the time to do a tire/wheel combo for a decent price, otherwise i wouldnt have went with them. i got 2 bullit deep dish 17x10.5 with 315's on them shipped for 600 i think.
* and also i was running 275/40's before i went to 315's and i noticed a slight difference in traction for the better. Now i just have those on the front
