Do Bigger Tires Affect Towing Capacity?

Do bigger tires affect towing capacity? This is a question that many people ask themselves when they are considering what type of tire to purchase. Bigger tires seem like an easy answer, but it’s not that simple. The reality is that there are a lot of factors which affect your vehicle’s ability to tow other vehicles and trailers. In this article, we will discuss the effects of larger tires on your vehicle’s towing capacity so you can make the best decision for yourself!

Many people make the mistake of assuming that bigger tires increase towing capacity. While it’s true that larger tires will have more ground contact, and therefore can better handle acceleration under load (like pulling or pushing a trailer), they do not in any way increase your tow rating.

Do Bigger Tires Affect Towing Capacity

Tires are one of the most important components on your car. They provide traction to help you get into and out of tricky situations, they keep you from hydroplaning in wet conditions, and they allow for a smooth ride when it isn’t raining outside- but did you know that tires can also affect how much weight your vehicle can tow? This is because there’s more surface area that needs to be grabbed onto with bigger tires and less ground clearance underneath due to the higher profile.

Larger tires have an increased radius than smaller ones; this means that while larger diameter tire will still contact the same number of points as a small diameter wheel if both were spinning at the same speed (so long as all other variables are equal), the larger diameter tire will travel a greater distance. This means that, with an increase in both size and speed of your tires, you may not be able to tow as much weight than if you had smaller wheels on your vehicle.

What are some things I should keep in mind when considering whether or not to invest in new tires?

Do Bigger Tires Affect Towing CapacityIf you need more hauling capacity than what is currently available from the factory for your particular make and model of car, it might be a good idea to upgrade your stock wheels by installing bigger ones without going too far outside of the wheel’s recommended rim width range; this way there won’t be any major changes other than just increasing how much load can fit onto each axle.

If your tires are worn out and you need to replace them, but don’t want to sacrifice hauling capacity as well, it might be a good idea to invest in taller rather than fatter tires. A higher profile tire will have the same contact patch size as a lower one; this means that while there may not be any extra weight on each axle with larger wheels installed (assuming all other variables remain equal), the increased height of these new additions will allow for more load.


Be sure to keep these factors in mind when considering whether or not bigger is better! Not only does changing sizes affect how much weight can be towed by an individual vehicle, but they also impact fuel economy because different diameter tires require different amounts of force to spin, which means that there will be a change in the car’s aerodynamics.
