Hi, Well winter time here in Chicago is just too much for the F1 Super car tires and is much as I hated too drop money on some more new tires seeing that the F1s are 90% new, but there just not made for winter weather. I bought and installed a set of Yokahoma Prada Spec X all season tires and they are great for my needs. I only rode the F1s for a month back in April when I got the 392, In may I put on my summer wheels and tires and just recently put the stock wheels and tires back on and witnessed right away that the F1s are no good in snow. So that's the only reason im selling these tires. So if anyone is interested I only want $300 and the buyer pays for shipping. Thanks!
