About ThisProduct

The Westlake SU318 H/T is an all-season tire made for crossovers and SUVs that spend most of their time on pavement. In this 285/50R20 size, its a good match for larger wheels on modern SUVs, giving you a steady, everyday feel for commuting, errands, school runs, and long highway drives.

In normal driving, this tire is set up to feel smooth and predictable. Its the kind of tire that should make your SUV feel calm on the freeway and easy to place in your lane, without making every crack in the road feel harsh. Around town, its designed to track straight and respond cleanly when you turn into parking lots, merge, or make quick lane changes.

Rain is where most people want extra confidence, and the SU318 H/T is built with channels and many small gripping edges to help move water away and hold on when roads are wet. That helps in real-life situations like stopping at a rainy intersection, driving through freeway spray, or heading home after a storm when the pavement still looks shiny.

For longevity, its treadwear rating points to a solid, everyday lifespan for a touring-style SUV tire, especially if you keep up with rotation and maintain proper air pressure. One honest limitation: its not meant for harsh winter conditions or deep snow, so if your winters bring frequent ice or heavy snowfall, youll want a dedicated winter tire for that season.

About Us

We didn't build Only Tires for us — we built it for you. Drivers who want straight answers, guaranteed fitment, and a tire that actually suits their vehicle and their life. No pressure. No guesswork. Just the right tire, delivered.

Shipping & Processing

We ship to the Lower 48 states for the advertised price. Tires typically take 1-2 business days to arrive (US48). Shipping timelines are provided on each product page. We can ship outside of the continental US for an additional charge. Contact Us for additional shipping rates. The buyer is responsible for all fees and paperwork beyond standard freight charges.

Delivery Inspection (Damage) - Ship to Home Only

UPS/FedEx ground shipments do not require a signature. Inspect the products as quickly as possible and follow up with us if necessary.
Notify us within 48 hours of receiving the order if any damage is found after delivery.
Very large tires may ship via freight. Inspect every piece BEFORE signing any documents. If damaged, please make full notes on the delivery paperwork before signing.

Returns & Cancellations

Returns

When vehicle information is provided, we review every order before it ships to help ensure proper tire fitment. If your tires are installed and do not properly fit your vehicle, they may still be returned as long as they meet our return condition guidelines.

Return requests must be submitted within 30 days of delivery to qualify for a return. Once approved, we will provide instructions for safely returning your tires. Refunds are issued to your original payment method after inspection. If the return is related to a fitment issue or an error on our part, return shipping fees generally do not apply.

All tires include the manufacturer’s warranty, and our team is available to help with sizing, fitment, returns, or warranty questions. If you need assistance before or after ordering, please contact us.

For full details, please review our complete Returns & Fitment Policy on our FAQ Page.

Cancellations

Cancellation requests or order changes should be submitted as soon as possible, as orders are processed quickly and may already be in progress. Return shipping fees may apply depending on the order status, but they may be waived if requested within 24 hours or if the error is on our end.

Manufacturer Warranty

All tires carry a full manufacturer's warranty. The buyer is responsible for shipping costs related to the warranty. All warranty returns must be approved by the manufacturer before shipping. If you'd like to start a warranty claim, visit our Warranty Center.
