The 285/65R20 Tires Explained

Tire Size Specifications: Width, Aspect Ratio, and Diameter

To better understand the 285/65R20 tire size, let’s break down its dimensions:

  • Width (285): This number represents the tire’s width in millimeters. A 285mm width indicates that the tire is relatively wide, offering a larger contact patch for enhanced traction and stability.
  • Aspect Ratio (65): The aspect ratio is the percentage representing the tire’s sidewall height in relation to its width. In this case, the sidewall height is 65% of 285mm. A higher aspect ratio generally means a taller sidewall, which can improve ride comfort.
  • Diameter (20): The diameter, measured in inches, refers to the size of the wheel that the tire is designed to fit. These tires are meant for 20-inch wheels.

Primary Applications: Off-Roading and All-Terrain Use

The 285/65R20 tire size is commonly used for off-roading and all-terrain driving. With a wider contact patch and taller sidewalls, these tires can provide better traction and stability on various surfaces, including dirt, gravel, and mud. Additionally, the increased sidewall height can improve ride comfort on rough terrain.

Popular Brands Offering 285/65R20 Tires

Several well-known tire manufacturers produce 285/65R20 tires, catering to a wide range of preferences and budgets. Some popular brands include:

  • BFGoodrich: Known for their rugged all-terrain and mud-terrain tires, BFGoodrich offers the All-Terrain T/A KO2 in this size.

Performance Implications for the RAM 1500

Fitting the RAM 1500 with 285/65R20 tires can have a noticeable impact on its performance. This section will discuss some of the primary aspects that may be influenced by tire size, including handling, ride quality, and fuel efficiency.


The 285/65R20 tires’ wider contact patch can lead to improved traction and stability, which may positively influence the RAM 1500’s handling, especially on rough or slippery terrain. However, the larger tires may also affect the steering response, making it feel less nimble in certain situations.

Ride Quality

The increased sidewall height of 285/65R20 tires can contribute to a more comfortable ride, particularly on uneven surfaces or off-road terrain. The taller sidewalls help to absorb impacts from potholes or bumps, reducing vibrations transmitted to the cabin.

Fuel Efficiency

While larger tires may offer some performance and comfort benefits, they can also negatively impact fuel efficiency. The increased rolling resistance and added weight of the 285/65R20 tires may result in a decrease in the RAM 1500’s overall fuel economy. The specific change in fuel efficiency may vary depending on the tire brand and model chosen.

Necessary Modifications

In some cases, fitting the RAM 1500 with 285/65R20 tires may require modifications, such as suspension alterations or wheel well clearances. This is particularly true if the vehicle is equipped with stock wheels and suspension. Consult a professional mechanic or tire specialist to determine if any adjustments are necessary for your specific vehicle.

Weighing the Pros and Cons

Before deciding whether to fit a RAM 1500 with 285/65R20 tires, it’s essential to consider the potential benefits and drawbacks of this setup. By evaluating both the advantages and disadvantages, truck owners can make an informed decision based on their individual needs and preferences.

  1. Accelerated Tire Wear: Depending on the specific tire model and driving conditions, the larger tires may experience more rapid wear, which could lead to more frequent replacement.
  1. Possible Modifications: Fitting the RAM 1500 with 285/65R20 tires might require suspension adjustments or wheel well clearance modifications, which can increase the overall cost and complexity of the installation.

By taking these factors into account, RAM 1500 owners can make an informed decision regarding whether 285/65R20 tires are the right choice for their vehicle, given their specific needs and preferences.

5Th Gen Ram 275/65R20

The 5th generation Ram trucks were introduced for the 2019 model year. These trucks feature a number of improvements over their predecessors, including an updated design, new engine options, and improved interior and exterior materials. The 5th gen Rams also offer a wider variety of wheel sizes and tire options than previous generations, giving owners more choices in how they customize their trucks.

One popular wheel and tire combination is the 275/65R20 setup. This article will provide detailed information about this particular option, including specs, benefits, and drawbacks. The 275/65R20 tires are a good all-around option for those who want a balance of off-road capability and on-road comfort.

These tires are slightly larger than the standard 265/70R17 tires that come on most 4×4 trucks, but they’re not so large that they sacrifice fuel economy or become difficult to handle on the highway. The extra 10mm of width (over the standard 265mm) can make a big difference when driving in deep snow or mud, and the taller 65 sidewall helps smooth out bumps and provides better traction on loose surfaces. There are a few things to keep in mind if you’re considering switching to 275/65R20 tires.

First, because they’re slightly wider and taller than standard tires, they may rub against your truck’s bodywork or suspension components when turning or going over bumps. It’s always a good idea to check for clearance before installing new tires. Secondly, these tires can be more expensive than other options; depending on your budget and needs, you may want to consider cheaper alternatives like 255/80R17s or 265/75R16s.

Overall, though, the 275/65R20 is a great option for those who need a little extra size without sacrificing too much fuel economy or handling ability.

If you’re in the market for a new set of tires for your Ram 1500, you may be wondering what size to choose. If you’re looking for a versatile tire that can handle both off-road and on-road driving, the 285/65R20 Ridge Grappler is a great option. Here’s a closer look at this popular tire size:

The 285/65R20 Ridge Grappler is an all-terrain tire that’s designed for both on- and off-road use. The tire has a tread pattern that’s optimized for traction in mud, snow, and sand, making it a great choice for those who like to take their Ram 1500 off the beaten path. The Ridge Grappler also features Nitto’s proprietary “Sidebiter” technology, which helps the tire grip better when cornering or traversing uneven terrain.

On the road, the 285/65R20 Ridge Grappler performs admirably. The tire is quiet and comfortable, even when driving on rough roads or highways. And thanks to its all-terrain design, the Ridge Grappler provides good traction in wet or dry conditions.

So if you’re looking for a versatile all-terrain tire that can handle both off-road and on-road driving, the 285/65R20 Ridge Grappler is worth considering.

285/65R20 Vs 275/65R20 Ram 1500

To help you make a decision, let’s take a look at the differences between these two tire sizes. The first number in each size (285 or 275) refers to the width of the tire in millimeters. The second number (65 or 60) is the aspect ratio, which tells us how tall the tire is in relation to its width.
