I needed to replace my old worn cracked tires and came across these Summit Ultramax HP A/S for a low price with many positive reviews. So far i am very happy with them. The car rides great and I have no complaints with the tires. I like the look of the treads and with being direction rotation hopefully they perform better in the rain and snow. Ive driven a bunch of miles on them, highways, backroads, rain and they seem to handle great and the car feels planted to the road. Hopefully they last a long time. I will update if there are any issues. i bought the tire installation and that did not go to well. The tires were delievered to the tire shop fine. I received numerous text and email confirmations on the scheduled appointment, I had even called the tire shop days ahead to confirm. Except when I got to the tire shop at the scheduled time the shop claimed they didnt have any appointment for me and that they were busy and i could just leave the car. I couldnt just leave the car since i wasnt near my house and didnt have a ride. I specifically made an appointment so i could wait for the tires to be installed. I ended up calling Amazon customer service to figure out what is going on, after over 1hr and being transferred to 3 different reps one of them was finally able to call the tire shop directly and talk to them and straighten it out. I still waited 4hrs for the tires to finally get installed. I don't blame Amazon, i think the tire shop was playing games which is unfortunate. To top it off when i got home i was cleaning the wheels and noticed the tire shop broke two center caps and just glued them in the rim. I work on my car all the time and know the center caps were not broken and there was certainly no glue used to install them. I cannot believe the tire shop wouldn't even tell me about the broken center caps and try to hide it by using glue.

This is my first time purchasing tires from Amazon instead of tire rack. Had them shipped directly to my house and put them in the back of my car and dropped the car off to get them swapped out just like tire rack with any local installer. Shipping was quick and hilarious having tires show up on my front door. I read multiple reviews across several weeks before I purchased these. I like to purchase midtier high-performing all season tires that provide decent traction, quite and comfortable road noise with an exceptional dry performance for braking and handling without breaking the bank financially. Installed on a 2010 Lexus RX 350 SUV. Time will tell on the durability but after a few weeks of driving, I am extremely pleased with the value and quality. No hydroplaning issues, no problems with NVH and very good performance in general road conditions. Have not had the ability to test them in ice or snow yet.

I received my tires a day sooner than what was expected and they were not damaged. I have been riding on the tires for about a week and half now and they are smooth riding. Not a whole lot of road noise either. Great quality tire for a good price.

These ride quieter than the ~150 dollar Vredestines they replaced. Good handling, low road noise, great ride quality, good speed rating at 130mph (not that I intend on driving that fast, but usually indicative of a higher quality tire. Plus, I drive spirited half the time). At 60 bucks a tire, these are unbeatable. Michelin, Continental, etc can keep their almost 200 dollar tires. Great tire at a great price. I also am a fan of the tread design. Used on my 2012 Mazda 3 5 speed sedan.

I've never heard of the brand Summit, but the reviews were pretty good, only a few bad reviews. I had them installed at a local tire shop. It was a rainy day, the tires had sort of a strange look to the tread pattern, but once I started to drive on them, the differences with the OEM Hankook Kinergy GT H436 was quite evident. These Summit tires were quieter, smoother riding and had more traction in the rain and today it was not raining and the same was true. This is the second day of driving on these new tires and I am quite satisfied with them, great price and good performance overall. As far as mileage, I won't be able to tell for a while. But this appears to be a great tire at a really good price, definitely would recommend. It's been two months now and been raining a lot locally. This Summit tire is definitely superior in literally every way when compared to the factory Hankook that cost more than twice as much. I would definitely buy these Summit tires in the future. Smoother, quieter, and handles better in both wet and dry surfaces, can't ask for more.

These Summit Ultramax AS XL tires are great!! I spent hours researching all the tires on Amazon. I looked at the reviews, total number purchased, the tire specifications, the reliability, especially the safety of the tires, and lastly the price of each tire. My priority was safety and type. I had needed all season type tires with a good tread wear rating too. I had narrowed it down to four different brands of tires available on Amazon. The Summit Ultramax all season XL (the XL stands for being able to carry a heavier load on each tire. It does not have anything to do with size. It is a strength load description only.) So, here I am now. After driving on the these tires for awhile, I'm happy to report that they are doing great! I'm glad that I trusted all the info enough to purchase the tires. I had them professionally installed and balanced. No problems with them and they have a really good grip on the roads even when it's raining. They are a great purchase from Amazon and it's a bonus that the price is great too. These tires are a wonderful fit for my car! (My old tires were Continental brand but the price of those are too high now.) I recommend for people to enter your basic vehicle info onto the Amazon website first to help ensure that you find the correct size tires for your vehicle, in the type and style that you like. Brief update: I added 2 pics of one of the tires after driving through muddy, gravel roads. These tires have such a good grip on all types of roads I've driven on and through lots of different kinds of weather. They are holding up great. I highly recommend these tires. 🌟🌟🌟🌟🌟
