The best 245/45ZR18 100W XL tire depends on whether you prioritize all-season use, warm-weather performance, a full set, or track-focused driving. The Fullway HP108 is an all-season option, while the Lexani LXUHP-207 is designed for performance vehicles in warmer conditions. Mastertrack sells a set of four, and Aplus targets racing use. The Horseshoe Sleipnir is the closest size-and-load alternative, but its listed speed rating is 100Y rather than 100W.
| Tire | Best For | Key Difference |
|---|---|---|
| Fullway HP108 | All-season use | All-season traction and XL construction |
| Lexani LXUHP-207 | Warm-weather performance | Water-channeling grooves and stated tread-life coverage |
| Horseshoe Sleipnir 2 | UHP driving and a two-tire set | 100Y speed rating; temperature-sensitive compound |
| Aplus Pro Racing | Racing-oriented dry grip | Semi-slick directional tread |
| Mastertrack M-TRAC HP | Replacing all four tires | Packaged as a set of four |
Fullway HP108: Best For All-Season Use

The Fullway HP108 matches the requested 245/45ZR18 100W XL specification. Its product details describe an all-season, high-performance radial tire with a black sidewall and 4-ply rating. Fullway lists it for trucks and SUVs, so check the vehicle maker’s tire requirements before choosing it for another vehicle type.
Best for: Drivers seeking the listed size and rating with all-season traction. Its stated XL extra-load construction and radial design are useful comparison points when matching a replacement tire to the vehicle’s specifications.
Limitation: The listing does not provide specific wet-weather, snow, or mileage performance details beyond its all-season description and UTQG 380AA information. Confirm that the tire’s intended use suits local conditions.
Lexani LXUHP-207: Best For Warm Weather

The Lexani LXUHP-207 is listed in 245/45ZR18 100W XL and is designed for performance-oriented vehicles in warmer weather conditions. Its wide lateral grooves are described as helping move water out of the tread to enhance hydroplaning resistance. The listing also states a 50,000-mile limited manufacturer tread-life warranty.
Best for: Drivers who want a performance tire for warm-weather use and value the listed tread-life coverage. The water-evacuation feature may also be relevant for driving on wet roads.
Limitation: Lexani specifies warmer-weather use, so this is not the clearest choice for drivers seeking a tire for cold-weather or winter conditions. Review the manufacturer’s warranty terms for coverage details.
Horseshoe Sleipnir 2: Best For UHP Grip

This listing is for two 245/45ZR18 XL tires with a 100Y speed rating. Its rating differs from the requested 100W, so verify the vehicle’s requirements before considering it as a replacement. Features include an asymmetrical tread, four wide water-channeling grooves, and an optimized footprint intended to support traction, braking, and cornering.
Best for: Buyers seeking a two-tire set with ultra-high-performance features who have confirmed that the 100Y rating is suitable for their vehicle.
Limitation: The listed compound’s grip is compromised when temperatures consistently fall below 45 degrees Fahrenheit. The package contains two tires, not four, and rims are not included.
Aplus Pro Racing: Best For Racing Use

The Aplus Pro Racing tire is listed as 245/45ZR18 100W XL. Its semi-slick directional tread is designed for dry grip and high-speed stability. The product information also identifies a high-grip, heat-resistant racing compound and reinforced belts intended to support durability at speed.
Best for: Drivers prioritizing racing-oriented dry performance. The directional tread and heat-resistant compound distinguish it from the all-season and warm-weather road-focused options in this guide.
Limitation: The provided features do not establish all-season capability or wet-weather performance. Avoid choosing it solely for year-round street use without checking the manufacturer’s intended-use guidance.
Mastertrack M-TRAC HP: Best For A Set Of Four

Mastertrack lists a set of four M-TRAC HP tires in 245/45ZR18 100W XL. The product details give a load index of 100, a W speed rating, and an XL load range. Its asymmetric tread and pitch design are intended to support cornering stability and responsive control.
Best for: Buyers replacing all four tires who want the exact listed size, load index, and speed rating in one set. The listing also gives a maximum pressure of 49 psi; use the vehicle placard or manual for the correct operating pressure.
Limitation: The claimed 20% longer tread life is based on internal testing, according to the listing. Treat it as a manufacturer claim, not a guarantee of results for every driver.
Buying Guide: How To Choose A 245/45ZR18 100W XL Tire
What do 245/45ZR18 100W and XL mean?
The size and service markings describe tire dimensions and performance ratings. “100” is the load index, while “W” is the speed rating; “XL” means extra load. The tire must meet the vehicle manufacturer’s required size, load capacity, and speed rating. Do not assume a tire with a different speed letter is interchangeable without checking those requirements.
Should you choose all-season, warm-weather, or racing-oriented tread?
Choose based on climate and driving conditions, not the word “performance” alone. The Fullway is described as all-season. Lexani is intended for warmer weather. Aplus emphasizes racing-oriented dry grip, while the Horseshoe compound has a stated cold-temperature limitation. Compare the maker’s guidance if you regularly drive in rain, cold, or snow.
Are you buying one tire or a complete set?
Check package quantity before ordering. Mastertrack is listed as a set of four, Horseshoe as a set of two, and the other product names describe individual tires. If replacing fewer than four tires, ask a qualified tire professional about matching tread and wear to the remaining tires.
Frequently Asked Questions
Does 245/45ZR18 100W XL match every 18-inch wheel?
No. The size must match the vehicle’s approved specifications, and wheel fitment depends on the vehicle and wheel setup. Check the owner’s manual or tire placard.
Can I use a 100Y tire instead of 100W?
The Horseshoe listing has a 100Y rating, not 100W. Confirm with the vehicle manufacturer or a tire professional that the different rating is appropriate before buying.
Which option is explicitly described as all-season?
The Fullway HP108 is described as providing all-season traction. The Horseshoe listing also says all-weather, but notes reduced grip below 45 degrees Fahrenheit.
Which listing includes four tires?
The Mastertrack M-TRAC HP listing specifies a set of four. Verify quantity on the product listing before ordering.
