The weight capacity for the 245 75 R 17 is 1120 kgs while that of the 285 70 R 17 is 1280 kgs indicating that it can safely carry more weight than its smaller counterpart without compromising its performance or safety features.

Fuel Efficiency

When it comes to fuel efficiency, the 245 75R17 and 285 70R17 tires offer similar performance. Both tires are designed to be more efficient and reduce drag on the road, resulting in lower fuel consumption. The main difference between the two tires is that the 245 75R17 is a slightly narrower tire than the 285 70R17, which can help with improved fuel economy. Additionally, the narrower tread pattern on the 245 75R17 may also help reduce rolling resistance and improve fuel efficiency.

Traction Ability

When it comes to traction ability, both tires offer excellent performance in wet or dry conditions. The 245 75R17 has a slightly narrower tread pattern than the 285 70R17, which can help provide improved traction in wet conditions by allowing more water to escape from under the tires surface. On dry surfaces, both tires provide excellent grip and stability due to their wide contact patch and tread patterns.

Pricing Difference

The pricing difference between the two tires largely depends on where you purchase them from. Generally speaking, the 245 75R17 is typically priced slightly lower than the 285 70R17 due to its narrower size. However, this may not always be true as prices can vary depending on brand and retailer.

Durability

In terms of durability, both tires offer excellent performance and are designed for long-term use. The 245 75R17 has a slightly narrower tread pattern than the 285 70R17 which helps reduce wear over time due to its reduced contact patch with the road surface. Additionally, both tires feature high-quality rubber compounds that help improve their lifespan and resist punctures or other damage from road debris or other objects encountered while driving.
