Atturo AZ850 275/50R20XL 113Y BSW

So far, so good
Got these as a budget tire to test fit and function of this size on the rear my 5th gen Camaro SS. I put them on a 20×10.5 wheel, and the sidewall does bulge a bit. Probably a non-issue of you’re loooking for straight line performance, but might swim around a bit in corners, we’ll see as I get more miles on them. Would probably be better on an 11″+ wheel. Just got them Wed 11/23 (ordered Sunday night), and they are date coded 2623 (July of 2023), so not old stock that’s been laying around a warehouse for a few years. Rubber is supple and fresh, pretty soft which is a given for the 320 treadwear rating. My car is pretty much stock and I can spin them thru first gear, but they do want to hook more than the 275/40 Toyo’s (500tw) I replaced with them. I imagine they’ll be ok in the rain with the wide channels but I think they went a bit overboard with them myself. I feel they could have backed off a bit, given us a little more rubber meeting the road, and still built a good tire for wetter weather. Both of the tires I got balanced with <1oz of weight, which is pretty impressive for a cheap tire. I'll get several heat cycles on them before pushing them too fast, but with a "Y" speed rating I expect them to perform to my needs.I will update this review as time passes. I've seen good and bad about these tires. Hopefully my experience will be good .Time will tell on how long they last, but if you're buying a 315 wide tire with a 320 treadwear rating, you shouldn't be expecting to get 50k miles out of them anyway.Update 3/4/24: Still have these on the back of the car, and bought a set of 285/35/20's for the front. Put those on 9" wide wheels. The 285's look more like they belong on the 9" wheel than the 315's do on a 10.5" wheel. The 285's also have a very prominent wheel protection lip on them, the 315's have one too, just not nearly as significant. Still haven't had any real warm weather yet, best I've run them around in is about 78 degrees. On asphalt the rears still want to spin fairly easily, on concrete they do much better (but most tires do). Went from 245 wide 500tw up front to these 285 320tw, so of course they have better grip. I think I'm going to leave this setup on the car for the first track day I have coming up in April and see how they do when leaned on pretty heavily. If they do OK, I'm going to get a pair of 305/35/20's swapped onto the rear. I think they'll compliment my 10.5" wide wheels better. Overall, they rode decent enough before I started suspension upgrades for the track which of course make the ride more rigid but I'm trying to bring the car more neutral as the understeer built into these cars is pretty horrendous. I will eventually run these on the street only, and get a set of dedicated track wheels/tires for playtime. Just trying to get some balance worked out before I start chewing up expensive 200tw tires.Again, will update as I learn more. Not disappointed in these tires at all for their price point. Given the latter, I doubt I'll be doing any top speed runs with these tires even though they're Y speed rated. Just not going to trust my life and my car to a $500 set of tires. But these have been in excess of 100mph a few times so far and didn't notice anything out of the ordinary.

Great value so far
So far these seem like a great buy at less than 1/2 price the big names. They are definitely wider than most of 305s I’ve messed with, even have some bulge on my wheels where a 285 Michelin and Hankook looked stretched.They ride great so far but we only mounted them a day ago. 10 miles home went fine, definitely had a mile or so of flat spotting from just sitting overnight but that smoothed out fine. 60 mile trip to office went well with mixed driving.If the flat spotting is the only issue I have with these I will be buying many more 👍👍

Dangerous on wet roads
No traction in the rain. Put them on my challenger RT. Nice tires when the roads are dry but if the roads are wet the quality of the tire is horrible and extremely dangerous to have on the car.

Best tire out there
Thesea re by far the best tires I’ve used to day. Out these in my 21 Charger and couldn’t be happier. The rode quality is smooth and soft. Takes pothole very well putting less strain on the suspension. Very quiet ride with amazing grip
