Tire is the most important part of a vehicle because it maintains contact of the vehicle with the road, which affects performance, efficiency, and traction of the vehicle. The heavy vehicles that carry loads or used for off-road travels, need sturdy tires that can complement the higher driving demands of such vehicles. For this purpose, there are two main options, i.e. 8-ply and 10-ply tires. Now, the question comes, what are the differences between them? Well, in this article, we have explained in detail about 8-ply and 10-ply tires, how they differ, and what features they offer. Let’s get started by knowing about what actually the ‘ply’ means.
What is Ply in tires?
It will be helpful to explain what the term ply rating means in the context of a tire prior to getting into the details of the differences. Originally, tire makers incorporated actual layers of cotton in the construction of tires, specifically called plies. The higher the number of plies, the stiffer the tire. However, current tire construction boasts of material such as steel and polyester; therefore, the term ply rating is misleading as it is not ‘true’ plies. Rather, it points to the toughness of a tyre and the number of kilos it can bear. These ratings show the weight that can be supported by a tire, the tire’s ability to carry load, and the durability it offers under pressure.
8-ply vs 10-ply Tires
Now, let’s discuss how 8-ply and 10-ply tires are different.
Load-Carrying Capacity
Coming to the differences between 8-ply and 10-ply tires, one of the main differences is the load-carrying capacity. This is especially important for the vehicles that are used to transport heavy loads or towing trailers.
8-Ply Tires (with Load Range D) are designed for use under moderately heavy loads. 8-ply is used in light-duty trucks, SUVs or vehicles that sometimes tow medium sized trailers or carry loads. A standard 8-ply tire can have the load carrying capacity of about 2600 lbs per tire.
10-Ply Tires (with Load Range E) are built to take more load; thus, it is suitable for heavy-duty trucks, commercial trucks, and vehicles that are used for towing frequently. Typically, the load index of a 10-ply tire can go up to and over 3,000 lbs per tire based on the tire size.
Durability
8-ply and 10-ply tires both come with durability, but the 10-ply tires are better for heavy-duty and longevity of the tires. 8-ply are also sturdy but they might wear faster if exposed to heavy loads more frequently. 10-Ply tires have greater load-carrying capacity and stronger, thicker sidewalls that offer safety against punctures, damage, etc. They are designed to last long when used under stress and especially when used off-road and loaded with heavier items. They provide additional strength making them appropriate for use by vehicles that work in difficult terrains most of the time.
Towing and Hauling
8-Ply tires are all-rounder tires since they are comfortable yet stable enough to carry a heavy load. They are useful for tasks like pulling camper trailers or moving building materials for small projects. However, if your vehicle does not have high work loads or pull equipment, 8-ply tires are enough.
10-ply tires offer more support and balance when towing and guarantee that your vehicle can handle the extra load without pressurizing your tires to the point without compromising tire safety.
Fuel Efficiency
Tires play an important part in the fuel efficiency of a vehicle. Heavier tires generally end up using slightly more fuel as compared to lighter tires. 8-ply tires are lighter than the 10-ply, and therefore give a better fuel economy. This can be quite significant for regular drivers making frequent short travels and even for those who undertake long highway journeys. 10-ply tires are heavier which makes them consume more fuel for driving. Using 8-ply tires instead of 10-ply tires makes a difference in fuel efficiency.
Off-Road Performance
8-Ply Tires are comparatively lighter in construction and thus can give better performance during off-road driving. They provide adequate grip on slightly off-road surfaces. However they may not be much suitable for severe off road conditions which require additional protection against punctures or damages.
10- Ply tires have stiffer sides, and can better withstand pressure which makes them suitable for tough road conditions such as rocky areas and extreme weather. Although they have firmer riding than 8-ply tires which is useful for rough terrains, the added security and strength of the tires makes it ideal for most people who go off road often.
Comfort and Quietness
For those drivers who opt for comfort, 8-ply tires usually give a better ride quality. They do have more comfort, so they are able to better take in shock and imperfections that might be present in any road. This makes them suitable for normal road use and on highways. 10-Ply Tires provide extra capability when it comes to weight carrying, and they generally endure longer than 8-ply tires; however, they are stiffer, and provide less shock resistance. With higher load-carrying capacities, the tire’s construction has to be stiffer, which results in providing a rougher ride.
Pricing
Compared to 10-ply tires, 8-ply tires are relatively cheap in the market. For a vehicle that does not often pull big loads or tow large trailers, the 8-ply tire can save you big money. 10-Ply tires are a little more expensive than their 8 ply counterparts. They are more expensive initially, while being more durable, able to support much more weight, and being more protected, which makes the extra cost worth it.
Final Words
To sum up, the decision to use 8-ply or 10-ply tires simply depends on your requirements and habits of car use. So, if you are using a light-duty truck or SUV and you need more comfort and fuel efficiency, with a rare load carrying, 8-ply tires will most probably be perfect for you. If you use a powerful vehicle or SUV, and your vehicle often pulls large trailers, or if you drive on tough terrains, 10-ply tires will be better as they are much more robust, stronger and can bear much more load.
