An Audi dealer installed 245/40r18 93h tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40r18 97h. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. After discovering the mismatch, the concern was reported to the dealer and Audi, but the dealer stated the 93h tires were acceptable rather than providing a safety-based correction. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the vehicle may have been operated with under-rated tires and because the issue can affect handling, braking, tire durability, suspension/wheel components, and safe vehicle control. Tire/repair-order records, door-jamb placard evidence, load-index comparison evidence, and dealer communications are available.
