I wish Firestone didn't discontinue the SZ-50's because they are some fine tires for a decent price.
IMO, I think Goodyear tires are extremely overrated. Are they good tires? Yes, but for the price, you can get something just as good and save some $$$
The thing about tires these days, especially these past few years, is that there is so much selection and the online places have really put the local stores into action. It used to be that you had your local store and that was it. But with Discount Tire and NTB coming up very big these past few years, the competition has benefited the consumers.
I have read some very good things about Kumho tires. I haven't used them but a guy I used to work with has used them and liked them.
