About ThisProduct

The Westlake SU318 H/T is an all-season highway tire made for crossovers and SUVs that spend most of their time on streets and highways. In this 255/60R18 size, its a sensible pick for everyday driving like commuting, errands, and long weekend trips, where you want steady grip and a calm ride more than anything sporty.

In normal use, this tire should feel predictable and easy to trust. The grooves and small cuts across the tread help move water away so youre less likely to feel that floating sensation when you hit standing water on the freeway. On dry pavement, its set up to track straight and feel stable when you change lanes or take a curving on-ramp without needing constant steering corrections.

Comfort is a strong point here. The tread layout is designed to keep road noise down, so youre less likely to hear that steady hum on concrete highways or rougher city streets. That can make a school run or a road trip feel a little less tiring, especially in an SUV where tire noise can echo through the cabin.

For longevity, Westlake backs the SU318 H/T with a 50,000-mile warranty, which lines up with what most drivers expect from a daily-use tire when its kept properly inflated and rotated. One honest limitation: its meant for paved roads and light winter conditions, so if you regularly deal with deep snow, ice, or muddy trails, youll want something more winter- or off-road-focused.

choose this tire if:

You want a quiet, comfortable tire for daily driving and highway miles
Rainy-day confidence matters for your commute
Your crossover or SUV mainly stays on paved roads

Its a practical, no-fuss choice for normal driving where comfort and steady grip come first.

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
