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.
You may go to our website and read through the aftermarket warranty policy brochure at https://www.kumhotire.com/fr-ca/global/warranty 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.
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.
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.
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.
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.
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. To get more info about road hazard coverage, click here to download the warranty brochure PDF.
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.
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.
