What can happen if I exceed the tow rating for my vehicle? The tow rating of any vehicle is based on numerous factors. The best advice is do not exceed the tow rating for any vehicle. If you do, you’ll be overloading the suspension, overextending safe braking distances, and experience further reduced and possibly unsafe passing ability.
