This vehicle is designed for two 245/35r21 (HLC/99Y) tires on the front wheels, and two 265/35r21 (HLC/103Y) tires in the rear wheels. When I took delivery of the car from the manufacturer, it was incorrectly outfitted with three 245s and one 265; one of the rear wheels had an incorrect tire installed. Attempts to resolve the issue with Lucid have been fruitless, and I am concerned that it may be a widespread issue. ##Timeline##: [2022-09-26] -- I accepted delivery of my 2022 Lucid Air Grand Touring [2022-11-26] -- I discovered that one of my rear tires (I don't recall which side) was incorrectly sized [2022-11-27] -- I reached out to Lucid customer care/warranty, and received a reply the following morning [2022-12-15] -- While taking a left turn in wet and cold conditions, the car briefly lost traction and ran over a curb, resulting in damage to the vehicle that would take several months to repair. There were no injuries nor third-party property damage. (I'm not sure if this loss of traction was related to the tire mismatch) [2023-02-09] -- I contacted Lucid again about the OEM tire mismatch issue. The Lucid team promptly replied with a promise of enlisting the service specialist team [2023-05-08] -- Repairs are completed by an third-party authorized Lucid service shop [2023-05-12] -- Having heard no response, I replied to the email thread again. The Lucid team promptly replied with a promise that they would follow up shortly. I have not heard from them.
