Although they look like a car tire, there are much worse tires. I really wanted to rid of mine (due to looks), but I just can justify it. If they were horrible, I would have bought different tires by now. They are good for 90% of what you'll drive on.
They are rated "good - excellent" in every category. If you can get a decent trade on them, go for it. Otherwise, I wouldn't give them away. It may be tough to sell them privately as well.
