About ThisProduct

The Westlake SU318 H/T in 255/70R18 is an all-season tire made for everyday crossovers and SUVs. Its aimed at drivers who want a calm, predictable tire for commuting, errands, school runs, and road trips, without paying for a more aggressive or sporty setup.

In normal driving, this tire should feel smooth and easy to live with. The sidewall height in this size helps take the edge off potholes and rough pavement, which is nice if your daily route includes patched city streets or older highways. Steering response is designed to be steady rather than sharp, so it feels relaxed and controlled when merging, changing lanes, or cruising at highway speeds.

Wet-weather confidence is a big part of an all-season SUV tire, and the SU318 H/T uses wide grooves and plenty of small edges in the tread to help move water away and keep grip when roads are shiny after a downpour. That can translate to less slip when pulling away from a stoplight in the rain and more reassuring braking when traffic suddenly slows.

For longevity, this tire is built with daily mileage in mind, so its a sensible option if you rack up miles year-round. One honest limitation: while it can handle light snow and cold snaps, its not the best choice for frequent deep snow, icy hills, or unplowed winter roads where a dedicated winter tire makes a noticeable difference.

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.
