About ThisProduct

The Westlake SU318 All Season in 275/45R20 is a practical tire for everyday driving on vehicles that use larger 20-inch wheels, often SUVs and similar daily drivers. Its meant for people who want steady, predictable traction year-round without paying premium pricing, and it comes with a 50,000-mile warranty to back up normal commuting mileage.

In day-to-day use, this tire is built to help you feel planted in the situations that matter most: merging onto the highway, cruising at steady speeds, and making quick stops when traffic suddenly stacks up. In the rain, an all-season tire like this is designed to move water out from under the tire so youre less likely to feel that light, floating sensation when you hit standing water in the right lane.

Comfort and noise are usually what you notice after the first week. For school runs and errands, you can expect a generally calm ride over typical bumps and patched pavement, though it may not be as hushed or as smooth as top-tier touring tires on rough highways. Longevity should be solid for a daily driver if you keep up with basic care, and the mileage warranty gives you some peace of mind if you rack up lots of miles.

One honest limitation: all season doesnt mean all winter. If you deal with frequent snowstorms, ice, or steep untreated roads, a dedicated winter tire will feel more secure and stop shorter.

choose this tire if:

You want an all-season tire that makes sense for commuting, errands, and road trips
You drive a vehicle with 20-inch wheels and want a tire backed by a 50,000-mile warranty
You prioritize confident everyday traction, especially in wet weather

Its a sensible, no-drama choice for normal driving when you want reliable grip without overthinking it.

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.
