How Many Miles Should I Buy a Used Semi Truck?

Buying a used semi truck is a great way to save money while still getting a reliable, powerful vehicle. But how many miles should you look for when making your purchase?

The answer depends on several factors, including the make and model of the truck, its age, and its overall condition.

When considering mileage, it’s important to remember that each truck is different. Some models are more reliable than others and can handle higher mileages with less maintenance and repair costs.

Generally speaking, however, the rule of thumb is that a used semi truck should have no more than 400,000 miles on it. Anything over this amount should be examined closely for any signs of wear and tear.

Another factor to consider is the age of the truck. Newer trucks typically have higher total mileages because they tend to be driven more often than older models.

However, even newer trucks can experience significant wear and tear if they are not taken care of properly or if they are subject to extreme stress or environmental conditions.

It’s also important to take into account the condition of the vehicle before making your purchase decision. You’ll want to inspect the bodywork for any signs of rust or corrosion as well as check all mechanical components such as brakes and suspension for any potential problems. Visually inspecting components such as spark plugs, belts and hoses can also give you an indication of how well-maintained the vehicle has been in its lifetime.

As a general rule of thumb, look for a vehicle with no more than 400,000 miles on it and make sure all mechanical components have been inspected thoroughly before signing on the dotted line.
