About ThisProduct

The Westlake SU318 H/T in 255/55R20 is an all-season tire made for everyday crossover and SUV driving. Its a sensible choice if your week looks like commuting, errands, school drop-offs, and the occasional highway trip, and you want a tire that feels predictable without making the ride harsh.

In normal day-to-day use, this tire is set up to feel smooth and steady. It should track confidently on straight highway stretches and feel easy to place in your lane when traffic gets busy. Around town, its the kind of tire that aims for a comfortable ride over cracks and patches rather than a sporty, stiff feel.

Rain is where most drivers notice a tire the most, and the SU318 H/T is designed to help you stay composed when roads get shiny. It uses built-in paths to move water away, which can help reduce that floaty feeling when you hit standing water in the left lane. For everyday wet braking and on-ramps after a storm, its meant to inspire more confidence than a worn or bargain tire with a simpler tread.

For road noise and longevity, this tire leans toward the touring side of the spectrum, so it should stay relatively quiet on the freeway and deliver solid mileage when you keep up with rotations and pressure checks. One honest limitation: while its fine for light winter conditions, its not the best pick for frequent deep snow or icy mornings where a dedicated winter tire makes a clear difference.

choose this tire if:

you drive a crossover or SUV for daily commuting and weekend highway trips
you want steady wet-road confidence without a stiff ride
you prefer a generally calm, low-drama driving feel

Its a practical, year-round option for normal driving and typical weather.

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.
