Tires and Performance

The convenience of vehicles must be paid with the price of your car and their maintenance cost as long as we have and drive them. It will take quite a lot from time to time but it is necessary to make sure the vehicle will run or work properly. One of the most important parts that affect your car’s performance is the tire because while they are equally black and round, different models and products are also going to be different.

Tire Size

Tire size is an important factor in your tire itself that directly affects the performance and characteristic of the drive. Upsizing them has been a trend for quite some time and for reasons ranging from improving the look to improve the performance such as in bad weather conditions and increasing the ground clearance. But, it is not always the bigger the better because it still has both good and bad sides as the effect of the design.

The good side is it can improve grip and traction because large and wide tires have more rubber on the surface so it provides more contact with the road hence the better grip and traction. It is also improving cornering and braking due to the same reason. On the bad side, a larger tire means heavier as well and this requires more energy to turn which is why your fuel will most likely dry up faster too. The same reason also affects steering to become heavier and slow in acceleration.

Tire Pressure

Not only the size, tire pressure is also affecting the fuel efficiency because if your tires are under-inflated, this causes the engine to use more fuel to move the car and in general the drop in pressure can cost fuel consumption by roughly 3%. The pressure is affecting their lifespan too because it increases the friction and causes the rubber to heat up excessively which means it will wear out faster as well or even risk of an accident.

Tread Depth

Another important factor that affects your tire is the tread depth which is often boasted by tires that are designed for off-road application or all-terrain types like Nitto Ridge Grappler Vs Toyo AT3 because the application requires this design. The thicker tread overall will give better traction and be very visible in affecting stopping time while also helping in gripping into loose or uneven surfaces. It is also the convenient indicator to decide when to change into a new set such as by using the Lincoln penny test.

About Nitto Terra Grappler G2 and Cooper Discoverer AT3

Changing to a new set of different tires is not a guarantee that it will perform better than the stock tire so it is convenient to stick with your old tire but, there are times when we want to improve the reliability as well such as when challenging new terrain or want to change the characteristics of the drive itself. Among the tire types, all-terrain and all-season are two of the most versatile to choose because they are designed to handle various different conditions.

Choosing a new brand of tire can be quite confusing because of the amount of options but, it doesn’t mean that we can’t shop quickly because it is easier to see what other similar owners are choosing for their vehicles since chances are you will like them as well. Popular models are famous for a reason and named brands are good options in general such as Nitto and Cooper Tire. The two are no strangers in the market with their extensive line of both versatile and specialized tires.

For those who love to do some adventures, there are plenty of options to consider from the collection and among those, Nitto Terra Grappler G2 and Cooper Discoverer AT3 are two ideal variants to consider. We have talked about the two in previous comparison with other popular all-terrain tires and they are working really well for many owners which is why they are among the favorite as well. None of them are budget options but seem to last decently long to give a better value.

The Terra Grappler G2 is a balanced combination of on and off road tire and it is probably one of the best too in all-terrain collection. It is a bit similar to the Ridge Grappler but the latter is more aggressive and better for off-road traction especially if you are dealing with loose surfaces often. On the other hand the AT3 or AT3 XLT as there are several variants in this line is designed for heavy load and ideal for rock or gravel terrain.

Nitto Terra Grappler G2 Features

Before checking what Nitto Terra Grappler G2 and Cooper Discoverer AT3 can offer, let’s first see the tire because they are quite interesting. Starting with G2, this new tire is coming with the brand new compound from Nitto that is claimed to be able to maintain the longevity and treadwear, despite being an all-terrain. It is also backed with treadwear warranty to cover 50k miles on the LT-metric and 65k for the hard metric sizes. Many of the sizes are also available in 3PMSF rated.

The Grappler G2 is made to be tough with coupling joints as you can see on the sample picture above in order to connect the outermost of its tread blocks to the center blocks hence it is more rigid to sustain stress. There are full depth siping all over the tread blocks in order to improve the traction in rougher condition.

Cooper Discoverer AT3 Features

The Cooper Discoverer AT3 in XLT variant is also not far behind with extensive thought on the design area. This tire is made with Cooper’s shred-resistance silica compound combined with their new-generation tread pattern. It has the Even Wear Arc Technology which optimized the shape of this tire’s footprint to help with balancing pressure and improving handling as well as even the contact for even treadwear. The stone ejector is also useful to prevent puncture when you are driving off the road.

Since you will most likely be driving on various terrains, the AT3 is featured with Rugged Traction Shoulders as you can see on the sample picture above with alternating scoop and cleat lugs as well as biting edges for better grip on rock or thick and slippery mud. In addition, the deep, circumferential channels and wide lateral notches will improve the hydroplaning resistance.

Nitto Terra Grappler G2 and Cooper Discoverer AT3 On the Road

Now for the most important part, let’s see how Nitto Terra Grappler G2 and Cooper Discoverer AT3 perform when installed. First thing first both of them are not lacking anything on the road and just as comfortable as typical all-season tires out there. The rugged design still feels smooth and while not as quiet, they are not annoyingly noisy as well. Dry road traction is never a problem with predictable steering and cornering stability for both sets of tires.

Wet traction is similarly amazing though not as impressive as the dry surface. The stopping distance is good and they feel firm as well when driven on rainy season while there is no issue for hydroplaning too. However, side by side we also feel that the drive is more confident with AT3, especially on traction both on dry or wet surfaces.

Nitto Terra Grappler G2 and Cooper Discoverer AT3 for Off-Road

For all-terrain tires, being good on the road is not enough because they need to be great off the road too. In this area the Discoverer AT3 is also performing slightly better because overall it is giving you a more reliable traction. Both of them are ideal for your weekend adventures and work really well in towing your vehicle across loose or gravels. They are also reliable for light climbing but probably not with sticky mud or clay as they will need larger lugs to get away from those properly.

They are all-season and can handle different weathers, making the two perfect for typical environments. In comparison however, while you can go with ease even during winter with any of the two, the AT3 is gripping to the surface slightly better, including with snow.

Nitto Terra Grappler G2 vs Cooper Discoverer AT3

These tires are what you want to go for their performance and convenience. What’s great is they are equally reliable so we do think you won’t regret choosing any of the two. There are however, small differences in traction due the AT3 ability to grip better and it is not only making your dry traction even better but also more reliable during off-road and snowy conditions.
