Frequently Asked Questions

What is the correct tire pressure for my car?

The correct tire pressure will be shown in one of three places – a placard on the driver's side door jamb, a placard inside the glove box or listed in the owner's manual. Tire pressure specifications are meant for when the tire is cold; therefore, if the vehicle has been driven or the tire has been sitting in direct sunlight, the tire pressure may read higher than the manufacturer's specification and should not be adjusted until the tire is cold.

When should I rotate my tires?

Tire should be rotated in accordance with the vehicle manufacturer's recommendation. If no recommendation is shown in the owner's manual, tires should be rotated every 5,000 miles.

How do I know the difference in tire patterns – Asymmetric, Directional and Symmetric?

Asymmetric – The tire will have "Outside" printed on one side of the tire and "Inside" printed on the other side of the tire. A properly mounted tire will show the "Outside" side when it has been mounted on the vehicle. An asymmetric tire will have differences in tread pattern design between the inside and outside of the tire tread area, which necessitates proper mounting.

Directional – A directional tire will have an arrow and the word "Rotation," indicating the direction the arrow should roll when the vehicle is moving forward. If the arrow does not roll forward when the vehicle is moving forward, the tire has been mounted improperly. Most directional tires appear to have a "V" design to the tread.

Symmetric – This is a standard tire and will not have any of the above printed on the sidewall.

Where can I find a local authorized Kumho Tire dealer near my area?

Where can I get general information about filing a warranty claim?

You may go to our website and read through the aftermarket warranty policy brochure at This has all the information on what is warranted, for how long and who is eligible. For original equipment tires, please refer to the limited warranty brochure kept in your new vehicle's glove box.

How can I find the warranty coverage specifics for my tire?

Go to our website and find your tire at

On your tire's page, a warranty symbol, as shown to the right, will show whether the tread pattern carries road hazard / roadside assistance and the number of miles covered by the limited tread wear warranty. There's also further discussion of the tread pattern's warranty in the description just under the tire name.

What's the difference between Original Equipment and Aftermarket & why are the warranties different?

Original equipment tires are ordered by the vehicle manufacturer for specific cars and already come equipped on new vehicles. Aftermarket tires are the replacements that the consumer purchases from a tire dealer. Some tread patterns are sold both OE and aftermarket. OE tires are ordered for specific cars; the warranty coverage type satisfies the vehicle manufacturer's request. OE warranty coverage does not include extended warranties; e.g., road hazard, tread wear/mileage, 24-hr roadside assistance, etc. that are available with certain aftermarket tire purchases.

Why can't I process my warranty claim directly with Kumho?

Our network of retail locations and distributors handle both the sale and return of Kumho tires. Best results come through filing the warranty return through the original selling dealer; however, any authorized Kumho Tire dealer has the ability to return a tire for you.

What do I do about this bulge on the sidewall?

Replace the tire immediately. If the tire has road hazard coverage and is within 2/32" of the original tread depth, it's a free replacement. Get more info about road hazard coverage at

Without qualifying for road hazard coverage, it must be verified the bulge is due to defect in order to receive pro-rated credit based on the unused portion of the tire.

My tires aren't wearing evenly. What happened?

This needs to be determined immediately by getting the tires inspected by an authorized Kumho dealer (preferably the original selling dealer). If the irregular wear damage is due to inflation problems or mechanical wear such as alignment, the warranty is void.

If by chance the bad wear is due to a workmanship or material defect, this can be confirmed by a tire technician and a claim can be filed to compensate you toward the unused portion of the tire.

I just had new tires installed and something is wrong with the ride. What do I do?

Return to the selling dealer immediately to have them determine the cause. If your tires make the car pull left or right, vibrate at certain speeds, won't balance or make entirely too much noise, it's possible a tire may be out-of-round. Getting the problem identified and the tire replaced quickly is imperative because of the limited amount of time allowed to return tires of an out-of-round condition (must be within 2/32" of the original tread depth).

Is ozone or weather cracking covered?

Yes, ozone cracking and weather cracking is covered for four (4) years from the date of manufacture.
