I bought these tires for my optima last year and didn't want to review it until i had them a full year to see how they did when i put them back on for winter this year. We generally have around 6+ inches of snow on the ground in winter here and the tires performed wonderfully. I never was stuck once even when the snow around a foot+ it let my little car plow right through and should no signs of slippage. My car doesn't have traction control or abs so for these tires not to spin on ice and snow means there great winter tires. Also after having them on through winter last year and removing them in April and then re installing this year for winter the tires barely show any signs of wear even with 6,000 miles on them. I bought another set for my wife's kia soul and there also working wonderful and no shes not scared when she has to drive to work in the winter.
