Introduction

I’m currently in the market for new tires for my truck, and I’ve come across two sizes that keep popping up: 285/75R17 and 285/70R17. I’m looking for some advice on which tire would be better for my needs, especially considering off-road performance, compatibility with my vehicle, and any necessary modifications.

Size Differences

First, let’s break down the size differences:

  • 285/75R17 has a larger sidewall, which can provide more ground clearance and potentially better off-road performance.
  • 285/70R17 offers a shorter sidewall, which might be better for on-road stability and handling.

I’d love to hear from anyone who’s used both tire sizes. What have your experiences been like?

Compatibility

I drive a [insert vehicle model here], and I’m trying to determine if I need to make any modifications to fit either tire size. Has anyone faced fitment issues with 285/75R17s? Do they require additional lift or trimming?

Off-Road Performance

I enjoy taking my truck off the beaten path, so performance in rugged conditions is paramount.

  • Does the taller sidewall of the 285/75R17 help with absorbing shocks?
  • Do the wider tires offer better traction on mud or sand?

Technical Specs and Resources

I’ve found various tire calculators and sizing charts online. If anyone has links to reputable resources or tools that compare these two sizes more directly, that would be super helpful!

Conclusion

Overall, I want to make an informed decision here. Thanks in advance for any advice or insights you can share about these tire sizes and their performance in different conditions. I appreciate it!

I’ve been looking into the differences between 285/75R17 and 285/70R17 tires as well! The main difference is the sidewall height. The 285/75R17 has a taller sidewall, which can provide better cushioning and a more comfortable ride.

That’s interesting! Does that extra height affect fitment in terms of fender clearance for lifts?

4

Yes, the 285/75R17 can rub on the fender well if your vehicle isn’t lifted enough. But it also provides more ground clearance. I personally prefer that extra bit of height for off-road conditions.

5

That’s the trade-off, isn’t it? More height can be great but could limit your fitment options.

6

Exactly! And with the 285/70R17, you’ll have a slightly wider contact patch, which can improve handling. However, it doesn’t give you as much ground clearance as the 285/75R17.

7

I’m actually in the market for new tires and can’t decide which is better. Is the height difference significant in everyday driving?

8

I find that ground clearance makes a big difference off-road, but do you think the height matters much for city driving?

For city driving, the 285/70R17 might be the better choice because it’s more stable at higher speeds due to less sidewall flex. But if you’re planning on doing any off-roading, I’d still lean towards the 285/75R17.

Great points! But I wonder if the difference in tire pressure affects performance between the two sizes? Anyone have thoughts on that?

I believe that while the pressure remains similar, the taller sidewall of 285/75R17 might be more forgiving in rough terrain.

12

So many variables to consider! Height vs. width can be a real headache. Anyone else feel like picking tires is like choosing a new pet? Just so many options!

13

Haha, that’s a good analogy! I’ve definitely felt overwhelmed by the choices. At least pets don’t require fitment checks!

14

True! But I suppose we want our choices to be the right ones for our vehicles and lifestyles.

15

In the end, it really comes down to your driving style and needs. If you off-road frequently, the 285/75R17 is probably the way to go. If mostly city, I’d stick with the 285/70R17.

I’m trying to decide between 285/75R17 and 285/70R17 too! I hear the 285/75R17 offers better off-road traction because of the larger diameter. Anyone experienced this?

17

That’s true! The larger diameter can improve ground clearance, which can be a game-changer on rough terrains.

Also, don’t forget about fuel efficiency! I’ve read that the 285/70R17 might be better for on-road use since it’s slightly smaller and can impact MPG positively.

19

Exactly! The difference in height can lead to less rolling resistance, which is key for fuel economy.

What’s your main use? If you’re mostly off-roading, the 285/75R17 could be a better choice. But for daily driving, the other might be preferable for handling.
