National auto warranty denied coverage due to tire replacement on my truck same size as it was sold to me with howell (800) 430-4428 National Auto Division, LLC 9 years in business 2323 Us Highway 9 Howell, NJ 07731-3392

The warranty was sold to me at time of purchase said it covers steering and suspention on my truck 1 month ago i replaced the tires with the same tires same size that it was sold to me with. 

Turns out that the tires are 1 inch taller and 2 inches wider than factory tires wich voids my waranty so the truck wont steer unless it is moving very dangerous but cant be covered by this warranty i paid over $4000 for this is very wrong shame on you National warranty customer service is very rude i will be requesting a refund.
