    • Great tires, long lasting
So far these have lasted me 2 winters in upstate New York. Going to be using them for a 3rd winter this year as well. Definitely recommend these tires!!

    • Worth the price!
These tires are fantastic! The ride is smooth and on point in wet or dry weather. I bought Summit tires to use during the summer. I have a full set of Pirelli A/S tires for the winter. And the Summit tires ride better than the Pirelli's... Shocking! And at a quarter of the price of the Pirelli's. I will definitely buy again. ... show more

    • Great inexpensive tire
I bought 4. 235/40R18s drove the whole summer with about 10,000 miles. Tires appeared to wear nicely. I run snow tires in a winter and soon will be putting these back on in the following month. They still look great.

    • Terrible ride quality, uneven wear after 1,800 miles
Yeah, I’ve bought cheap tires that have lasted at least 25,000 miles and they didn’t ride as bad as these. Somehow one of them was out of round from the factory. Pulled it off after about 1,800 miles and it’s already wearing unevenly. So that feeling of a wheel being unbalanced was just a problem with the tire. Awesome. ... show more

    • the tire is great, but…
in my opinion the tire is good, especially for the price relative to the size of the tire. i’m not a rubber expert though, just a guy fr. my ride is smooth, have not had any problems with hydroplaning, and it holds air like normal. the shipping, however, i did not like. the seller opted in for the tire to need to be signed for Without letting me know and i thought the delivery guy stole my tire since i wasn’t aware i had to sign for it 🤦🏾♀️ (the only way i found out was by checking through fedex’s website), so the first time the tire was attempted to be delivered i wasn’t home and had to wait all day the next day for redelivery. thankfully, i had that kind of time, but i couldn’t imagine being a normal person with a 9-5 needing to sign for ONE tire, or else having to print out a signature form and tape it to my door for the delivery guy. for the shipping inconvenience, i took a star ... show more

The tires look great an as expected. No problem getting them installed at a shop. The noise level is low and expected for these type of tires. I've had them for months now and the they are wearing evenly. They ride pretty well for low profiles.
