About ThisProduct

The Accelera Iota ST68 All Season in 255/45R20 is a practical choice for drivers who want a dependable everyday tire for a vehicle with 20-inch wheels. Its aimed more at normal commuting and family driving than anything sporty, and its built to handle the weight and pace of typical crossovers and SUVs. With a 35,000-mile warranty, its also set up for drivers who want a reasonable service life without paying top-shelf prices.

In day-to-day use, this tire should feel stable and predictable on dry roads, like when youre merging onto the highway or making quick lane changes in traffic. The V speed rating means its made to stay composed at common highway speeds, which helps it feel confident on longer trips and not floaty when the road opens up.

For rainy commutes, the Iota ST68 is designed to move water out from under the tire so youre less likely to feel that slippery, skating sensation when you hit standing water. That translates into more controlled braking and steering in wet conditions, like slowing down for a red light on a shiny, rain-soaked street.

Comfort and noise should be reasonable for daily errands and school runs, though it may not be as quiet or as plush as some premium all-season options. One honest limitation: like most all-season tires, its not the best pick for frequent deep snow or icy winter driving, where a true winter tire will feel noticeably safer.

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.
