Review

Read a detailed review of each tire if you are still hesitating which option you should choose.

The Ultrac Vorti is Vredestein's Max Performance Summer tire designed for drivers of performance sedans, sports cars, sporty coupes and high-powered luxury vehicles who want confident braking and high speed traction combined with precise and responsive steering in dry and wet conditions. The Ultrac Vorti excels in the warm dry and wet, so like all Max Performance Summer tires, it is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.

A high-traction tread compound delivers enhanced dry and wet braking and lateral grip and is molded into the asymmetric pattern of the Ultrac Vorti. The stable center rib improves steering response and precision, while the rigid, low-void outboard shoulder enhances handling. More void in the inboard shoulder aids wet traction and handling, and the wide, circumferential grooves help water flow through the contact patch for improved hydroplaning resistance.

Internal construction of the Ultrac Vorti features a two-ply, rayon casing for strength and durability. Two nylon reinforcement plies provide high-speed capability, and the wide, steel belts feature application-specific tuning. Tire sizes intended for front axles utilize a lower belt angle, while rear tire sizes use a high belt angle to optimize the balance between grip and stability in high-horsepower vehicles.

Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.

Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.

The Crugen HP71 is Kumho's Crossover/SUV Touring All-Season tire developed for drivers of crossovers, SUVs and light duty pickup trucks looking for a quiet, luxurious ride combined with all-season capability, including light snow traction.

The all-season tread compound of the Crugen HP71 is molded into a five rib, symmetric design featuring Kumho's Variable Pitch Technology that provides a quiet and comfortable ride while also allowing for easy rotation patterns to promote even wear and longevity. A rigid center rib provides solid on-center feel and combines with strong shoulders in aiding handling and steering response while also adding stability to combat irregular wear. Notches in the ribs and wide grooves in the shoulders combine with four circumferential grooves to evacuate water from the contact patch for hydroplaning resistance, and sipes and independent tread blocks create biting edges for traction in slippery conditions.

The tire's internal structure consists of a two-ply polyester cord body for enhanced ride quality and improved strength. Two wide steel belts sit on top of the casing and are reinforced by two spirally wrapped nylon cap plies, enhancing handling, durability and stability at highway speeds.

Tires Scores Compare

How we score

Would You Recommend?

N/A
N/A

Treadwear Performance

N/A
N/A

Treadwear is vital to many things, not just how often the tires need replacement. Hydroplaning and wet weather are both critical factors that wear down your tire quickly. The warranty covers any defects in what you bought but only for a limited period or when there's minimal tread left on them.

Wet Perfomance

N/A
8.7

The wet performance score is a new thing that tire manufacturers are trying to achieve. The hydroplaning resistance, wet traction, and steering response all influence this new grading system.

Hydroplaning Resistance
i

The hydroplaning resistance is measured by the hydroplane depth test and the dynamic aquaplaning test, which measures how much water can be accumulated on the tire's surface before hydroplaning occurs.

8.6
Wet Traction
i

Wet traction estimates the level of grip on wet pavement. Tread design with deep grooves dramatically improves confidence when driving in the rain as they channel the water out much better.

8.8
Steering Response
i

The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.

8.9

Dry Perfomance

N/A
8.9

Tires with good dry performance should be able to perform smoothly and safely, even when cornering aggressively.

Cornering Stability
i

A dynamic cornering test is often used to assess cornering stability under dry conditions.

8.9
Dry Traction
i

Dry traction level depends on many factors, including tread design, profile shape, and compounds.

8.9
Steering Response
i

The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.

8.9

Comfort Perfomance

N/A
9.1

The comfort performance score is designed to measure the balance between ride quality and noise level.

Ride Quality
i

The excellent ride quality means you do not feel the bumps or cracks on the road. Larger tires with thick and deep tread patterns decrease the number of jolts allowing you to glide over bumpy road textures.

9.1
Noise
i

If you would enjoy a quiet chat with the passengers while children are sleeping or listening to music, not the sound of tires, definitely pay attention to the noise score.

9.1

Winter Performance

N/A
8

Winter Performance score helps us understand if the tire is the appropriate option for winter conditions that your vehicle will face. Dedicated winter tires provide a firm grip when driving through snow and on ice. Performance winter tires boast a higher speed rating and better handling but deliver modestly lower ice and snow traction.

Light Snow Traction
i

Snow traction is the ability of a tire to push snow out of its path. When driving on packed snow, tires with good snow traction will help you accelerate and maintain control.

8
Deep Snow Traction
i

Deep Snow Traction test results compare how the tires deal with the deep snow. To successfully cope with the job, such tires should feature aggressive tread patterns, a tremendous amount of siping, and most elastic compounds.

8.1
Ice Traction
i

Ice traction tires feature ice grip and build friction when using the brakes or steering wheel to get through icy surfaces safely.

Size
i

Tire size may be indicated in two formats:
– metric (P255/45R18 103H)
– high flotation (30x9.5 R15 104 F C)
In the metric system, P - stands for the passenger vehicles (LT - for Light Trucks, ST - Special Trailer) with a width of 255 millimeters, aspect ratio (sidewall height) equal to 45% of the tire height. R means it is radially constructed with a diameter of 18 inches. 103 denotes the tire's load index and H determines the speed rating.
In the high flotation system, the first number (30) is the overall diameter of the tire, the second number (9.5) is the width in inches.

Max. load
i

The maximum weight that a tire can carry is the greatest amount of weight it's designed to bear. Because load carrying capability is dependent on a tire's size and construction, as well as how much air pressure is actually utilized, maximum loads are measured with the tire inflated to an industry standard inflation pressure.
