Westlake SL369 are budget all-terrain tires designed for minivans, SUVs, CUVs, and light trucks. They have an all-season capability and could be used year-round in both summer and winter conditions. These tires have pros and cons and we have discussed both in our detailed review below.
Westlake SL369 Tire Features
- SL369 has an open five-rib design to provide wet and dry performance in addition to off-road capability.
- The tread design is aggressive with deep lugs spaced out enough to help evacuate water, mud, stones and resist hydroplaning.
- SL369 is an all-terrain tire so the lugs are not as deep and spaced out like a mud-terrain tire. But they are large enough to give good handling and traction on a highway and in light off-road conditions.
- Zigzag sipes present on the tread blocks create biting edges for added traction under slippery and snowy conditions while retaining tread block stability for dry traction and handling.
Overall Westlake has done a good job with the tread design of SL369 making it capable to use in all weathers. Since SL369 is marketed as an all-season tire so you should expect it to perform well in light snow and winter conditions.
These tires are available in multiple load ranges from 4 ply load range B to 10 ply load range E. 4 ply tires are good for light duty trucks and SUVs like Chevrolet, Tahoe, Ford Expedition, Ford f-150 etc. The 10 ply rated tires are for your heavy-duty pickup trucks and vans. Westlake has given a lot of options in the load range category covering different types of vehicles according to their load-bearing capacity.
SL369 Road Test
Ride Quality and Tire Noise Review
SL369s need about 500 miles to break in, just like other tires, and you would feel the ride quality improves over this period. These are balanced tires that offer a smooth ride on the highway and city without any turbulence or shaking. The impacts from bumps and potholes are absorbed by the strong sidewalls of SL39, improving the overall driving experience.
The main difference in A/T and H/T tires is the road noise. A/T tires create more road noise due to larger and spaced out tread blocks. Surprisingly, SL369 tire noise is noticeable but comparatively low compared to many other all-terrain tires. This could be attributed to zigzag tread block design that helps to reduce the noise level.
Handling and Traction Review
The dry and wet traction of SL39 is also commendable. You won’t experience any tire slippage and the SUV/truck seems planted on the road. They also grip well on the wet road thanks to the wide space between tread blocks which helps evacuate water effectively. If you are living in an area in the U.S with adverse weather conditions and heavy rain, SL369 tires can be relied upon for effective wet traction and hydroplaning resistance.
Handling wise, SL369 doesn’t have sharp steering response and it takes a little longer to turn into action. This non-responsive steering response is common in A/T tires, especially in big sizes. But, the road feedback is good with these tires and you know how much steering input you need in a corner or in an emergency maneuver. Don’t expect to take high speed cornering on these tires as they aren’t not made for this purpose.
Braking is also good in both dry and wet conditions. But you should be wary that budget tires usually lose their braking and traction, especially in wet conditions as they wear out. Westlake tires also don’t give the same performance throughout their tread life.
Snow and Winter Season Performance Review
Westlake SL369 also perform quite well in light snow conditions. The void between tread blocks and the siping gives a good grip on snow. The starting and stopping of the truck are also effortless and mostly without any major slippage or control loss. You can definitely rely on SL369 to get you through light snow conditions with good straight-line traction and cornering stability. But you have to keep in mind that these are not dedicated winter tires and there might be slippage if you brake or corner at a high speed on the snowy road.
Although SL369 are good enough for light snow, they might not be able to perform well in extreme winter with thick snow and icy roads. The braking distance would increase and the tires would slip and skid on the road. Its always recommended getting dedicated winter tires in this condition.
Off-Road Capability Review
Westlake SL369 A/T tires are designed for light off-road usage. They can perform well on gravel roads, beach and forest trails. But they cannot provide the traction on deep mud and very loose sand because these rugged terrains need more specialized M/T tires. Also, the sidewalls don’t have aggressive tread blocks and could be punctured on rock climbing.
Tread Life, Warranty and Tire Specifications
The tread life of budget tires is usually low and that is the biggest downside of Westlake SL369. You can expect a tread life of about 20K miles out of these tires. One more thing you should be aware of is that the tire traction is not same throughout the tread life. You would experience a deteriorating performance, especially in snow and wet conditions once this tire nears its overall life.
There is no Warranty offered by Westlake on SL369.
