Giti Tire USA and Continental Tire are issuing separate recalls that when combined affect more than 265,000 tires, according to the National Highway Traffic Safety Administration.

The Giti recall concerns 250,620 imported Primewell Valera Touring II tires (sizes 205/50R17 93V XL, 215/50R17 95V XL, 225/50R17 94V, 225/50R18 95T, and 205/65R16 95H); GT Radial Champiro Touring A/S tires (sizes 205/50R17 93V XL, 215/50R17 95V XL, 225/50R17 94V, 205/65R16 95H, and 225/50R18 95T); and Dextero Touring DTR1 tires (sizes 205/50R17 93V XL, 215/50R17 95V XL, and 225/50R17 94V).

These replacement tires for passenger cars, manufactured by PT. Gajah Tunggal TBK in Indonesia, might develop cracks in the lower sidewall and lose air.

“A loss of air pressure may result in sudden tire failure, increasing the risk of a crash,” NHTSA warned on its website.

GITI dealers will replace the affected tires, free of charge. The recall is expected to begin this month. Tire owners can reach Giti customer service at (877) 342­0882.

Continental Tire is recalling 14,567 Crosscontact LX20 tires (size P275/55R20 111S). They were manufactured from May 3-9 in 2015. The tires were sold as replacement tires as well as original equipment on General Motors full-size trucks and SUVs.

The Continental tires at issue may have insufficient adhesion within the belt package, resulting in tread wear, vibration, noise, or bulging areas on the tire, according to NHTSA.

“The insufficient adhesion can cause partial or full tread/belt loss, increasing the risk of a crash,” NHTSA said.

Continental Tire dealers will replace the tires, free of charge. The manufacturer, however, has not yet provided a notification schedule. Owners can reach Continental customer service at (888) 799-2168.
