ByLiberty Is Viral Desk Blog

285 75R17 has a larger sidewall height and is best suited for off-road applications, while 285 70R17 has a lower sidewall height and is better suited for highway driving.

285 75R17 Vs 285 70R17

285 75R17 and 285 70R17 are two standard tire sizes which provide different levels of performance according to their respective dimensions. The first number (285) denotes the cross-section width of the tire. The following two numbers (75 and 70) indicate the aspect ratio – the percentage of height relative to the width. The letter ‘R’ stands for Radial type construction and the concluding number (17) is used to denote wheel diameter in inches.

In comparison to 285 75R17, 285 70R17 offers a slightly shorter sidewall. As a result, it gives a feeling of being more responsive and planted on the road surface. Also, it provides better grip in wet or dry conditions for improved handling levels and braking distances in extreme conditions but comfort levels may be compromised in comparison to similar size tires with taller profiles like those of 285 75R17.

Size Comparison – 285 75R17 – 285 70R17

When comparing the size of the 285 75R17 and the 285 70R17 tires, there are two main things to consider: dimensions and weight. The 285 75R17 tire has an overall diameter of 34.3 inches, a section width of 11.2 inches, and weighs 44 pounds. The 285 70R17 tire, on the other hand, has an overall diameter of 33.7 inches, a section width of 11 inches, and weighs 43 pounds. As you can see from these numbers, the difference in size between the two tires is minimal but noticeable.

Advantages and Disadvantages – 285 75R17 – 285 70R17

The performance and traction benefits of the 285 75R17 tire compared to the 285 70R17 are significant. The larger profile of the tire offers more surface area with which to grip the road or off-road terrain while providing improved hydroplaning resistance. On the other hand, due to its smaller profile, the 285 70R17 offers slightly better cornering performance at high speeds than its counterpart.

Tread Wear Ratings – 285 75R17 – 285 70R17

Tread wear ratings give consumers an idea of how long a particular tire will last before it needs to be replaced. This rating is based on a standardized testing process that measures how quickly a tire wears down under certain conditions. The tread wear rating for both the 285 75R17 and 285 70R17 tires is 420 miles per month; however, this rating may vary depending on factors such as driving style and weather conditions.

Price Comparison -285 75R17 -285 70R17

When it comes to price comparison between these two tires, there can be quite a bit of variation depending on where you purchase them from and what type of discounts you can find online or at your local dealer’s shop. Generally speaking, dealer cost for both sizes is fairly similar; however, retail prices can vary significantly due to discounts or other promotional offers available at certain stores or online retailers.

Load Capacity of Both -285 75R 17-285 70 R 17

The load capacity for both sizes is determined by their axle weight rating as well as their tire load index number (TLI). The TLI indicates how much weight each individual tire can support when fully inflated; in this case, both tires have a TLI rating of 118Q which translates into 3195 lbs per tire when loaded evenly across all four wheels (for dual rear wheel vehicles). Additionally, both sizes have an axle weight rating that allows up to 8600 lbs when loaded evenly across all four wheels (8600/4=2150lbs per wheel).

Speed Rating

The speed rating of a tire is indicated by a letter, which corresponds to the maximum speed that the tire can sustain. The speed rating for 285 75R17 and 285 70R17 are both “E”. This means that they are both suitable for speeds up to 120 mph, or 193 km/h.

Year Models Fitting

285 75R17 and 285 70R17 tires can fit vehicles of different makes and models from various years. Depending on the vehicle, some brands may not be available in certain sizes or may require special fitment kits. It is important to check with the manufacturer for specific size requirements before purchasing tires.

Brand Variations

When selecting tires, it is important to consider reliable brands as well as availability of different sizes and models. There are several reliable brands that offer both 285 75R17 and 285 70R17 tires including Bridgestone, Michelin, Goodyear, Pirelli, Continental, Yokohama and more. Each brand offers different levels of performance depending on their construction processes and materials used.

Fuel Efficiency Impact

The difference in size between 285 75R17 and 285 70R17 can affect fuel efficiency due to the rolling resistance of the tire. Generally speaking, larger tires will have higher rolling resistance which leads to increased fuel consumption compared to smaller tires with lower rolling resistance. Additionally, using lower profile sidewalls (shorter sidewalls) also increases rolling resistance and decreases fuel efficiency so it is important to use appropriate sizes for optimal performance.

FAQ & Answers

Q: What are the size comparisons between 285 75R17 and 285 70R17?
A: The overall diameter for a 285 75R17 is 33.5 inches and the overall diameter for a 285 70R17 is 32.9 inches. The width of a 285 75R17 is 11.2 inches and the width of a 285 70R17 is 11.0 inches.

Q: What are the advantages and disadvantages between 285 75R17 and 285 70R17?
A: Generally, the performance of the 285 75R17 tire is better than the performance of the 285 70R17 tire due to its larger size providing more contact area with the surface. The traction of a larger tire like the 285 75R17 provides more grip, but it also has more rolling resistance which makes it slightly less fuel efficient than its smaller counterpart, the 285 70R17 tire.

Q: What are tread wear ratings for both tires?
A: Tread wear ratings provide an indication of how long a tire should last before needing replacement due to wear and tear. Tread wear ratings are measured in UTQG (Uniform Tire Quality Grade) which uses a scale from 100 to 400 to rate tires based on their performance in laboratory tests conducted by tire manufacturers. The tread wear rating for both tires,285 75R17 and 285 70R17, usually falls between 330-400 UTQG rating depending on their brands and models.

Q: What is the price comparison between both tires?
A: The price difference between both tires can vary depending on brand availability, dealer cost, retail prices, etc., but generally speaking,the 285 75R17 tire tends to be slightly more expensive than its smaller counterpart -285 70 R 17 – due to its larger size providing better performance overall compared to its smaller counterpart.

Q: What is the load capacity difference between both tires?
A: The load capacity rating indicates how much weight a particular tire can safely handle when inflated properly at maximum pressure rating indicated by manufacturer specifications. The load index of a285 75 R 17 is 117 while that of a285 70 R 17is 113 indicating thatthe28575 R 17 can handle more weight when inflated properly compared to its smaller counterpart -28570 R 17 – due to its larger size providing higher load capacity overall compared to its smaller counterpart .

In conclusion, the 285 75R17 is a larger tire than the 285 70R17, with a larger diameter and width. The larger tire will provide better ground clearance and improved traction in off-road conditions. However, the smaller tire will provide better fuel efficiency, handling and acceleration on the road. Ultimately, it depends on the driver’s needs and preferences when it comes to choosing between these two sizes.
