I've had these tires approx 2 yrs. They appear to have the same ride quality, if just a little better, as Bridgestones the car came with. I highly recommend them. i live in So. Fla, so naturally there are no snow conditions.
Upgraded my rims on my g8 to 20's so im running with these Proxes 4 Plus' as 245/35/20 all around. Going from a 45 series side wall to a 35 series side wall i expected the "rough ride" people complain about but i was shocked because my ride quality arguably got better, granted i went from mismatching balding tires to these new ones, but still, smaller side wall and seemingly smoother and softer ride? Impressive. Don't know what the guy who complained about these being loud is talking about his cabin must not be very quiet because these are very quiet even up to high way speeds. Drove through some HEAVY rain and felt like dry pavement. Cant speak for treadwear or snow driving since i just got these but will update, gave 'em 4's because other people on other websites gave treadwear and snow positive reviews so i'll give these the benefit of the doubt. based off reviews off other websites, my first impressions, price, warranty etc these appear to be some of the best UHP 4-season tires you can buy.
Surprised to see a couple people disappointed with snow performance given the fact I'm RWD drive and drove perfectly through some crazy snow storms last winter, 40 mile round trip commute and made it just fine. Don't believe me? Check out "pontiac g8 in snow" you youtube. Anyway, in my experience they are great in wet and snow. Bought my car used, these DWS' were on them not sure how far previous owner went on them but i've gone 17k miles and the DWS tread indicators are still perfect meaning i can drive in snow still, easily think they'd get another 15k miles so tread life seems fine too. Very quiet, very comfortable tire. Once again, surprised there are complaints about these tires, i guess tire reviews are like movie reviews, completely subjective.
I purchased these tires about a year ago, I thought that these tires were a good purchase at the time. After 5,000 miles, I just replaced all four because of belt separation. I will never purchase these tires again. Saving a few dollars in purchasing these discounted tires is not worth the expense in having to replace them after only ONE year :(
