Winter is coming...how much am I going to hate the stock Dunlops?

If you want extra protection, go to Discount Tire and sipe them. $10 a tire so $40 for all four.

I've never heard of this but I just read about it on their website. Seems like a pretty good deal. Sounds like a good idea for my wifes civic hybrid. Think it effects mpg at all?

I thought most tires (other than M/T's) come with siping? Does Discount just add more to what already comes with the tire?
