Choosing an all-terrain tire is a balance between highway comfort, loose-surface grip, load capacity, and price. The Westlake 24466004 SL369 in 275/60R20 targets drivers who spend most of their time on pavement but still want useful traction on gravel roads, job sites, and mild trails. Its main strengths are a road-friendly tread design, a 2,679-pound maximum load rating, and a budget-focused position. Its main limitation is equally important: this specific size is a Standard Load tire, not an LT or Load Range E tire for frequent heavy hauling or severe off-road use.
Quick Verdict
Rating: 7.5/10, recommended with caveats
Best For: Daily-driven trucks and SUVs that need affordable all-terrain traction for pavement, gravel, and light trails
Bottom Line: The SL369 offers a practical mix of road comfort and mild off-road grip in a common 275/60R20 size. Skip this Standard Load version if your vehicle requires an LT tire, higher load capacity, or severe-snow certification.
Before You Buy: Confirm the complete tire size, load index, speed rating, and load range on your driver-door placard or with a qualified tire professional. Amazon may display this tire as “10-ply,” but Westlake’s size chart identifies part number 24466004 as Load Range SL. Do not treat it as an LT275/60R20 or Load Range E replacement.
Key Takeaways
- Part number 24466004 is a Westlake SL369 all-terrain radial tire in size 275/60R20 115T.
- The manufacturer lists a 33-inch overall diameter, 11-inch section width, 12/32-inch tread depth, and 43.4-pound approximate weight.
- This size has a Standard Load rating and supports up to 2,679 pounds at 36 PSI, according to Westlake’s size chart.
- The tread uses variable pitch blocks, angled siping, wide grooves, and steel-belted construction to balance road comfort with light off-road traction.
- The tire is not marked with the Three-Peak Mountain Snowflake symbol, so it should not be treated as a dedicated severe-winter tire.
- The Amazon listing is for one tire. Mounting, balancing, valve service, disposal fees, and alignment are normally separate.

What Is the Westlake SL369?
The Westlake SL369 is an all-terrain radial tire made for SUVs and light trucks. The 275/60R20 115T version reviewed here is a roughly 33-inch tire designed for 20-inch wheels. It uses a symmetrical, non-directional tread with large blocks, angled sipes, and open grooves.
Westlake positions the SL369 as a mixed-use tire rather than a dedicated mud-terrain model. The tread is aggressive enough to find grip on loose dirt and gravel, but its variable pitch arrangement is intended to reduce road harmonics and cabin noise on paved roads. Steel belts add strength and help the footprint remain stable under normal truck and SUV loads.
This balance makes the SL369 most relevant to drivers who want an affordable step beyond a highway-terrain tire without moving to a heavier, louder LT all-terrain tire.
Who Should Buy It?
Best For
- Drivers whose vehicle specifies 275/60R20 with a load index of at least 115 and a compatible speed rating
- Daily highway and city driving with occasional gravel, dirt-road, or mild trail use
- Budget-minded truck and SUV owners who prefer a moderate all-terrain tread
Skip If
- Your vehicle requires an LT tire, Load Range E construction, or more than a 115 load index
- You regularly tow or haul near the vehicle’s maximum ratings
- You need a Three-Peak Mountain Snowflake tire for severe winter conditions
How the Westlake SL369 Performs on the Road
Dry Pavement and Highway Driving
Large tread blocks and a stable center section should give the SL369 a predictable feel in normal dry-road driving. The 115T service description matches both the Amazon listing and Westlake’s size chart, but your replacement tire still needs to meet the rating required by your vehicle manufacturer.
The variable pitch tread is designed to spread sound across different frequencies, which can make it quieter than a more aggressive mud-terrain tire. It will still produce more tread sound than many highway-terrain tires, especially as the tread wears or if alignment is off.
Wet Roads
Angled sipes and wide grooves create extra biting edges and channels for water. That design supports wet traction, but no tread pattern removes the need to slow down in heavy rain. Standing water, worn tread, low pressure, and excessive speed can still cause hydroplaning.
Gravel, Dirt, and Light Trails
The open block pattern is better suited to loose gravel and packed soil than a conventional highway tread. Shoulder blocks can add grip when the surface becomes uneven, while the grooves help clear some mud and debris. This is still a Standard Load all-terrain tire, so it is better matched to maintained trails and access roads than sharp rocks, deep mud, or repeated low-pressure off-road driving.
How It Performs in Real Use
Daily Commuting
For a truck or SUV used mainly for commuting, the SL369’s moderate tread gives you useful all-terrain styling and traction without the weight and stiffness of many LT tires. The 43.4-pound weight is reasonable for the size, which can help preserve ride comfort compared with heavier Load Range E options.
Weekend Gravel Roads
On cottage roads, forestry access roads, or job-site gravel, the tread blocks provide more edges than a highway tire. The 12/32-inch starting tread depth also gives loose material somewhere to move. Keep speeds sensible because gravel can reduce braking and cornering grip even with an all-terrain tire.
Light Towing and Cargo
The 115 load index equals a maximum rated load of 2,679 pounds per tire at the specified pressure. That number is not a stand-alone towing approval. Your vehicle’s axle ratings, gross vehicle weight rating, trailer tongue weight, wheel rating, and placard pressure still control what you can safely carry.
Winter Conditions
The SL369 can provide basic all-season traction in light snow, but this size is not listed as Three-Peak Mountain Snowflake certified. For frequent ice, packed snow, mountain travel, or areas with winter-tire laws, use a properly fitted winter tire or a verified severe-snow-rated all-terrain alternative.
Westlake SL369 Tread Life and Durability
The SL369 combines 12/32-inch tread depth with steel-belted radial construction. Westlake also lists a 40,000-mile limited mileage warranty for the SL369 line. The warranty is prorated and depends on conditions such as registration, proof of purchase, even wear, and documented rotations every 5,000 miles.
Real tread life depends on your vehicle, alignment, inflation, driving style, road surface, rotation pattern, and towing load. Heavy front-end weight and missed rotations can cause shoulder wear or cupping before the tread reaches its expected mileage.
Pro Tip: Record the installation mileage, register the tires, and keep dated rotation invoices. That paperwork matters if you later make a mileage-warranty claim.

Fitment, Installation, and Safety
A 275/60R20 marking does not guarantee fit on every truck or SUV with 20-inch wheels. Confirm the complete factory specification, including load index, speed rating, load range, rim width, wheel load rating, clearance, and any front-to-rear size difference. Aftermarket wheels, suspension lifts, leveling kits, and larger brake packages can change clearance.
Have the tire mounted and balanced by a qualified shop. Ask the installer to inspect the wheel, valve stem or TPMS service parts, lug hardware, and clearance at full steering lock. A wheel alignment is worth checking when you install a new set, especially if the old tires show uneven wear.
Use the cold inflation pressure on the vehicle’s tire-information placard or in the owner’s manual. The tire’s 36 PSI maximum-load specification is not automatically the correct daily setting for your vehicle. Check pressure at least monthly and before long trips or towing.
What the Design Suggests About Comfort and Noise
Westlake uses variable pitch blocks and siping to reduce road harmonics, while the large tread elements support stable steering response. Those features make the SL369 a more road-oriented choice than a mud-terrain tire. You should still expect some all-terrain hum, and noise may rise as the tread wears.
Ride comfort also depends on the vehicle and wheel setup. Because this version is Standard Load rather than Load Range E, it may feel less stiff on an unloaded daily driver. That same construction is why it is not the right substitute when an LT tire is required for load, durability, or commercial use.
Pros and Cons
Pros
- Balanced tread for pavement, gravel, dirt roads, and light trails
- Variable pitch design aims to limit highway tread noise
- 12/32-inch tread depth and steel-belted radial construction
- 2,679-pound maximum load rating in this 115T size
- 40,000-mile limited mileage warranty from Westlake, subject to terms
Cons
- Standard Load construction is not suitable where an LT or Load Range E tire is required
- No Three-Peak Mountain Snowflake rating for severe winter use
- Amazon specification fields conflict with the manufacturer on ply description and pressure
Is It Worth the Price?
The Westlake SL369 sits in the budget side of the all-terrain market. It offers strong value for the price when your priority is ordinary road use with occasional gravel or mild trail driving. You get a recognized size specification, steel-belted construction, a 40,000-mile limited mileage warranty, and a tread designed to control noise.
The value is weaker if you need premium winter performance, frequent rock protection, or higher load capability. In those cases, paying more for an LT-rated or Three-Peak Mountain Snowflake alternative can be the safer and more useful choice.
How It Compares to Alternatives
The Cooper Discoverer Road+Trail AT is worth comparing if you want a Standard Load 275/60R20 all-terrain tire with Three-Peak Mountain Snowflake certification and a longer published mileage warranty. The General Grabber A/TX is a more aggressive option with severe-snow certification and stronger off-road positioning.
The Westlake SL369 makes the most sense when price and daily-road manners matter more than maximum trail durability or winter certification. Compare the exact load range and service description, not just the size printed on the sidewall.
Frequently Asked Questions
Is the Westlake SL369 275/60R20 a 10-ply tire?
Westlake’s official size chart lists part number 24466004 as Load Range SL, or Standard Load. Amazon displays a 10-ply field, so confirm the molded sidewall and manufacturer specification before installation. Do not use this tire where your vehicle requires an LT or Load Range E tire.
What pressure should you use in the Westlake SL369?
Use the vehicle manufacturer’s recommended cold pressure on the driver-door placard or in the owner’s manual. Westlake lists the tire’s maximum load as 2,679 pounds at 36 PSI, but that is not automatically the correct operating pressure for every vehicle.
Is the SL369 suitable for snow and ice?
It can handle light snow as an all-season all-terrain tire, but this size is not Three-Peak Mountain Snowflake certified. Choose dedicated winter tires or a severe-snow-rated all-terrain tire for regular ice, packed snow, mountain routes, or legal winter-tire requirements.
Can you use this tire for towing?
You can tow only when the tire’s size and load rating meet the vehicle manufacturer’s requirements and the loaded vehicle remains within every axle, wheel, tire, and gross-weight limit. A 2,679-pound per-tire rating does not override your truck’s placard, payload rating, or trailer limits.
Does the Westlake SL369 include a treadwear warranty?
Westlake lists the SL369 under its 40,000-mile limited mileage warranty. Coverage is prorated and requires conditions such as registration, original purchase records, even wear, and documented rotations every 5,000 miles.
Does it come with road-hazard coverage?
Westlake has a road-hazard program that names the SL369, but its published terms say online sales are not eligible and the tire must be bought through an authorized dealer. Seller-provided protection may differ, so check the exact terms before purchase.
How often should you rotate the SL369?
Westlake’s mileage-warranty terms require documented rotation and inspection every 5,000 miles. Follow your owner’s manual when it specifies a different pattern or interval, especially on four-wheel-drive or staggered-fitment vehicles.
Does the Amazon listing include one tire or a full set?
The listing states a package quantity of one tire. Confirm the cart quantity before ordering, and budget separately for mounting, balancing, TPMS or valve service, disposal fees, and alignment if needed.
The Bottom Line
The Westlake 24466004 SL369 is a sensible budget all-terrain tire for compatible trucks and SUVs that spend most of their time on pavement and only need light-duty gravel or trail capability. Its road-focused tread, 12/32-inch depth, and 115T rating are useful strengths, but buyers who require LT construction, higher loads, or severe-snow certification should choose a different tire.
