These are about $75 a pair, and they recommend putting them on all 4 tires for RWD cars. And yes, you put them in the washing machine!
Again, I have no desire to deal with the expense, storage, or hassle of changing over to snow tires. In the past 5 years, I've probably had to drive in the snow once. I just want these for emergencies.
Can't find the RUDs in my size either.
