I'm a 25 year old girl and don't know much about tires. I do know it's time to buy new ones so I went online to check out some prices. I found on discount tires Barum Bravuris 2 40000 for 53 dollars a piece and at firestone FR710 65000 warranty for 69.99 dollars a piece. I usually would buy the one with the best warranty but the reviews say the barium's are really good...... Please help me...
