Atturo AZ850 Review: UHP Performance Tires at Half the Price

The Atturo AZ850 is the tire I recommend when someone walks in and says "I want performance tires but I'm not spending $300 a corner." It's Atturo's flagship ultra-high-performance summer tire, and it's the single best-performing product in our Google Shopping campaigns — 47.9X return on ad spend. That tells you something: people are searching for affordable UHP tires, finding the AZ850, and buying it.

Let me tell you why.

What Is the AZ850?

The AZ850 is a max-performance summer tire designed for sports cars, muscle cars, luxury sedans, and performance SUVs. It covers 72 sizes from 18" to 22", which means it fits everything from a Mustang GT to a BMW X5 to a Dodge Challenger.

The tread design uses an asymmetric pattern — stiffer outboard blocks for cornering grip, wider inboard channels for water evacuation. The compound is a high-silica mix that delivers good wet and dry traction without being so soft that you're replacing tires every 15,000 km.

The Price Comparison That Matters

Here's why the AZ850 exists and why we sell so many:

The AZ850 starts at $159. A set of four is under $640 before you even factor in our free shipping over $99. A comparable set of Michelin Pilot Sport 4S tires will run you $1,200+. That's $560 in your pocket — enough for a full set of winter tires.

Real-World Performance

Let me be honest: the AZ850 is not a Pilot Sport 4S. If you're tracking your car competitively and chasing tenths of a second, the Michelin is the better tire. That's not controversial — Michelin spends billions on R&D and charges accordingly.

But here's the thing: 90% of people buying UHP tires never see a track. They want a tire that grips well in corners, feels responsive, handles rain without drama, and looks good on their car. The AZ850 does all of that.

Dry Performance

Excellent. The stiff sidewall gives you immediate turn-in response, and the outboard tread blocks hold through corners without the squirm you get from cheaper all-season tires. On a spirited backroad drive, the AZ850 inspires confidence.

Wet Performance

Good. The four main circumferential grooves move water efficiently, and the high-silica compound maintains grip on wet pavement. It's not the class leader in wet braking, but it's far better than a budget tire and competitive with tires costing $100+ more.

Noise and Comfort

Surprisingly refined. For a UHP tire, the AZ850 is quieter than expected. The asymmetric pattern helps break up tread noise, and the ride quality is firm but not harsh. You can daily drive this tire without complaint.

Tread Life

Reasonable for the category. UHP summer tires are inherently softer compounds — they sacrifice longevity for grip. The AZ850 is competitive with similarly priced options. Expect 40,000-50,000 km with proper rotation, which is in line with what you'd get from a Nitto or Continental at this level.

Size Coverage

72 sizes is impressive for a brand this size. Here's a sampling:

• 18": 225/40R18, 235/45R18, 245/40R18, 255/35R18, 265/35R18
• 19": 235/35R19, 245/35R19, 255/35R19, 275/30R19, 285/35R19
• 20": 245/35R20, 255/30R20, 275/30R20, 285/30R20, 305/25R20
• 22": 265/35R22, 285/30R22, 305/25R22

If you're running staggered fitments on a Camaro, BMW, or Mercedes, chances are the AZ850 comes in your size.

The AZ850DR: Drag Radial Variant

For the straight-line crowd, Atturo also makes the AZ850DR — a street-legal drag radial that shares the AZ850 name but is a completely different tire. The DR has a much softer compound optimized for traction off the line, and it covers some exotic sizes like 305/30R19 and 335/25R22 that are hard to find in the drag radial market.

The DR runs $470-677 per tire — serious money, but it fills a niche that not many manufacturers cover. More on that in our AZ850DR review.

Who Should Buy the AZ850?

• Muscle car owners (Mustang, Camaro, Challenger, Charger) who want summer grip without the premium price
• Sport sedan drivers (BMW 3/4 Series, Audi A4/S4, Genesis G70) who want better tires than the factory all-seasons
• Performance SUV owners who want a sportier feel than their OE tires
• Anyone replacing expensive OE tires — if your car came with $350 Pirellis, the AZ850 is a legitimate alternative at half the price

Who Shouldn't Buy the AZ850?

• Year-round drivers in Canada — this is a summer tire. You need dedicated winters for our climate.
• Track day regulars — if you're doing HPDE events monthly, invest in a proven track tire like the Pilot Sport 4S or RE-71RS.
• Economy car owners — if you're driving a Civic to work and back, a grand touring tire like the AZ810 makes more sense.

The Verdict

The AZ850 is the best value in the UHP tire market right now. It delivers 85-90% of the performance of tires costing twice as much, in a wide range of sizes, from a brand that's been building a reputation in the performance space for over a decade.

We import these directly from the factory, which means you're getting the lowest prices in Canada without a distributor markup. A set of four with free shipping for under $700 is hard to argue with.
