Rated 5 out of 5 by from Great all around tire I took a chance on these being a somewhat new tire. I bought them in December of 2017 and just turned 10,000 miles on these tires. I thought it would be a good time to review them. The tire techs were pushing me toward a more aggressive tread. Where I live I drive my 03 F-150 98% of the time on hard roads. I found this tire to excel in all ways including the snow which I was a little surprised about. It is extremely quiet and reasonably priced.

Rated 5 out of 5 by from Great tires so far... I have a 2017 Ford Explorer with 255/50R20 and I just replaced my OEM Hankooks which I got 30k out of them which I understand is pretty good compared to what other have gotten out of their OEM Hankooks. I've compared the two tires and did a noise check on the same road while taking my car to get the new tires and then on that same road with the new Discoverer SRX. The SRX perform very well and are quieter than the Hankooks. Hope to send another reply when they have 65k on them and have performed well.

Rated 1 out of 5 by from Very Disappointed I'm a long time Cooper tire owner and I'm extremely disappointed with these tires. Have them on my Ford Flex. They have the worst road noise of any tire I've ever purchased. The factory tires were silent and these sound like an airplane engine. Have had them on for 10,000 miles and the road noise just increases. They handle well in Michigan winters but I would never buy these or recommend them to anyone. Tread wear is disappointing too. I was so concerned with the extreme noise I had my mechanic make sure that there were no mechanical issues with my vehicle. Sadly, these are the worst tires ever. I'm considering getting rid of them and buying new tires because the noise is so bad. Complete waste of money.

Rated 5 out of 5 by from Perfect for my Venza These tires added a quiet stability to this vehicle that I had no idea was possible. They were also excellent in this horrendous winter here in Pa.I have been buying Cooper tires for years for my Subarus and have been a happy return customer. These tires, and I know its only been about 4,000 miles, have exceeded my expectations. If you are a Venza owner (4 cylinder)and are looking for an upgrade in a 19"tire....give this one a try.

Rated 5 out of 5 by from smooooth 2016 Ford Explorer Sport 255/50/20 with 65,000 miles and 35.1 psi with consistent rotation at 5,000 miles. I’ll start by saying I’m a Michelin guy. These tires replaced the Premier LTX that were completely shot after 50,000 miles. Previously replaced the junk OEM Hankooks at 15,000 miles. After reading many, many reviews and being impressed with a set of Cooper AT3’s that I put on my 1999 Wrangler, I thought I would give the SRX’s a try on the Explorer. I was planning on switching to the Michelin Defender as well. I’m a road warrior and a “spirited” driver. I had the SRX’s installed by Tire Star in Wolcottville, IN and headed North to the UP of Michigan. They balanced them perfectly I might add. I left in ice and sleet which cleared after 100 miles, then heavy rain that changed to snow; and then blizzard conditions in the first 500 miles of driving. In three days, I can report in at 1000 miles on the clock. I first noticed how significantly quieter these tires are than the Premiers; so much so, I now realize that I have some wind noise coming from my passenger door that requires some minor adjustment. These tires start out rough and need about 5 miles to warm up in below freezing temps…and will step up about 3psi at speed to the 38psi mark; then they’re smooth as butter at 90mph. Unlike the higher performance Michelin…these need a warm up to smooth out. Remember this is 109H vs a 109V. You will notice a slight loss of performance handling, but a much plusher ride…so if you have an extra 200hp with a Livernois upgrade, these tires are not for you. They outperform the Michelins in Ice, Snow and Heavy Rain but will require some getting used to with spirited cornering as these tires are also 8 lbs heavier than the Premier…but they STICK! To be fair to Michelin…an honest comparison would be with the Defender, not the Premier’s. Thus far, I am extremely pleased with my decision to purchase and will update my review as time progresses. I like everything about them…and they have exceeded my expectations. They’re also very cool to look at! I’ll be back!

Rated 5 out of 5 by from Making my Tahoe great again! I bought my Tahoe right after the previous owner put the Cooper SRX on. These tires are amazing! We’ve had lots of rain and some snow recently, and these tires never lost their grip on the road. We also have lots of potholes right now, and the SRX has been brilliant in helping me dodge all of them. The confidence I have in these tires grows daily!

Rated 5 out of 5 by from Steady in the Snow My mechanic recommended Cooper SRX P255/50R20 tires to me when I asked for something that would be good in the Upstate New York winter. I've been driving through plenty of snow with these tires for 2 months now and haven't slipped a bit. Every time I'm making my way down a slushy road I'm grateful to him for telling me about Cooper tires!

Rated 5 out of 5 by from Good handling. These tires made a huge improvement in the handling of my Ford Explorer. They have been on for fall rains and winter snow here in Wisc. Very happy with traction and handling. Too soon to judge about mileage wear.
