The HTR Enhance LX2 is Sumitomo's Standard Touring All-Season tire designed for the drivers of coupes, family sedans and small crossovers and was developed to combine responsive handling and long life with all-season traction, even in light snow.

A high-silica, super microparticulate carbon compound enhances both strength and flexibility for improvements in wear and wet traction, while the asymmetric tread pattern focuses on all-season performance and reliable handling even as the tire wears. Optimized groove depth and even pressure distribution throughout the contact patch help prevent irregular wear, improving the usable life. The compound's high silica content enhances grip in wet conditions, while the straight, circumferential grooves and wide, lateral notches evacuate water from the contact patch for hydroplaning resistance. An increased number of sipes in the tread pattern create more biting edges for traction in snow and on ice, and utilizing 3D zigzag sipes helps retain tread block rigidity for handling, while cross-designed chamfers retain snow in the tread for snow-to-snow traction.

The internal construction of the HTR Enhance LX2 consists of a 2-ply polyester casing beneath two wide, high-rigidity steel belts. A spirally wound, nylon reinforcement enhances high-speed stability, and the high modulus bead insert improves steering response.

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
N/A

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.

Dry Perfomance

N/A
N/A

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

Comfort Perfomance

N/A
N/A

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

Winter Performance

N/A
N/A

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.

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.

Max. speed

The maximum speed that a tire with this type of tread can safely travel for an extended amount of time is indicated by the tire speed rating, which is usually shown by a letter or two.
