I see people bashing this tire, looks like areas with bad weather. I just replaced my optima 426's at 58,925 miles. I do happen to drive 140 miles a day (all freeway) and all in sunny San Diego - Orange County, so I cant say how bad they are in the snow. It does rain, but not hard, and again, people in San Diego cant drive in the rain, so your always slowing it down. I have never hydroplaned or had any issues feeling safe in the rain. My other vehicle is a Expedition on 40 mudders, so maybe that causes a comparison in my mind that makes me think this tire is better, I feel reading the reviews that I should not like them. But I have to say, what tire is going to go over 55,000 miles? Again, all freeway, and all very cautious (70 mph MAX) driving. They dont seem loud to me, the car goes where I want it to, tracks well, holds a straight line, etc. I cant say I have had any peel outs or traction loss but that could be the wimpy motor in the Fiesta, it really is a fuel economy car and the motor/tranny forces it to be driven that way.
Anyways, I just bought the Optima 426's again, so I'd have to say I like them, and they serve the fiesta well.
