Unusually rapid tire wear on front tires is going to require the 2nd replacement of all 4 tires within a 13 month period covering a total of 16,440 miles. The vset ofehicle was purchased used with new set of tires in 9/2018 (22,205 mi), by 3/2019, (31,648 mi) two tires were bald and required replacement of all 4 tires as car has all-wheel-drive.. again, by 10/14/2019 (38.650 mi) two tires are down to < 2/32nds (safety nubs) requiring the 2nd replacement of all 4 tires within a 13 month period. All tires have been per Kia specifications and speed rating (23560R18 103H). In all cases the tires have worn evenly and no alignment problems or subject to unusual driving conditions or use. Tires are rotated every 5,000 mi..mechanics consulted have not seen this unusual wear rate and acknowledge the even wear pattern and no alignment problem. Appears something is drastically wrong with the vehicle versus the tires.

Front brakes 8 & 8, rear brakes 7 1/2 & 7 1/2. service adviser suggest alignment. Service adviser reports vehicle alignment only needed minor adjustment, not significant to produce the wear and apparent loss of tread presenting on two front tires. Service adviser makes inquires on any extreme driving conditions including extensive driving on gravel roads or extreme stopping. As the sole driver of vehicle I can attest that vehicle has not been placed in any extreme driving situation. Vehicle driven approximately 650 miles per month. Dealer service adviser states he has never seen this in 20 years. He explains that at the next oil change, vehicle mileage at around 20,000 miles, tires will be checked and then rotated at the next scheduled time. The multi point inspection documentation does not denote any abnormal tire wear.. all systems checked green on dealer documentation. Photos of front tires attached.

The tire sticker at the side of the driver door does not state what the required load and speed index should be for the tire. The manual does not have any information on the load index, and has a vague speed index chart (rating letter vs. Speed) referring to passenger vehicles in general but no mention of this particular vehicle.
