265/70r17 vs 265/65/17

[jross20]

Currently I have 265/70r16 tires... I'm trying to figure out which size I want to get for my 17" Sequoia wheels.

I really want to avoid any loss of power or fuel economy... So yeah. Haha

Which would you go with? Or will the small change from my current size to 265/70r17 not be enough to be an issue?

To my mind, no. The difference between the 65 or 70 is in Sidewall height, which will affect the over height of the tire. That could change the way your truck's speedometer interprets "tire revolutions" to MPH which will LOOK to change your gas mileage.

My understanding that for highway mileage improvement, width is more of an important thing to consider. A narrower tire (assuming it is lighter as well) will be easier for the engine to turn.... gas saving. Consider a 245 width for better gas mileage.

Had P 245 65 16 on this when I bought it and switched to LT 256 70 17 on Sequoia wheels and the only difference I noticed is it handles better now! Also looks better!

I went from 265/70R16 to 265/70R17 with no noticeable difference. If you want to see the difference between the two sizes I like to use this tire tool: Tire Size Comparison

Interesting, so for the best mix of on and off-road do you guys think I should decrease the width?

For the cost and popularity I would just stick with 265/70R17's. There's not as much selection in the 255's or 245's. Here's another link that might help: Tire Size Chart It lists different tire sizes for a 17" rim and groups them by tire diameter (height).

Honestly I had a hunch that it would be better to go with a regular size.

What would you go with the 70? Or the 65? I'm really just curious to know if going up to 70 will have any noticable affect or if it will be miniscule

 

[Bad Luck]

I went with 265/70R17's. I haven't noticed any difference, but the tires I have are half tread light all terrains that I got for free. I'm also 4.30 gears so it's probably less noticeable for me than someone with 4.10's.

 

[Andy in Pa]

There will be NO difference between the 65 and 70... absolutely none.

Weight of the tires is the biggest factor.
Your stock wheels and tires were 60.5lbs each.
265/70/17 K02's C range tires with those wheels weigh 73 lbs each.
That's a 21% increase in rolling mass you have to push around. That certainly hurts performance.

Now, I'm running a wheel/tire combo that is even heavier than that, and I still average 17MPG with my 5 speed. Do I need more revs to get things done? yes but it's fine.

nose full affect

:lmao:

Noticeable effect?

You know, voice to text used to be good. It just blows now...

Anyway, alright so I guess I'll go with the 265/70r17 since the consensus looks like it will not affect things much.

Pretty sure the ones I have now are like 39 lbs and the ones I've picked are 42, so hopefully I will be okay. Haha

You'll be happy with them. They look good from stock height up to about 2.5" of lift and won't hurt performance much at all on the street.

If you get a bit of rubbing on the back of the front wheel wells, get an alignment with increased caster and it will be fixed.

When someone says increased caster I become nervous... When I had my second gen taco, I had a ridiculously long and painful ordeal of having 5.5 degrees of caster that could not be solved... I finally figured out after about a year that my aftermarket uca's we're labeled incorrectly. So after swapping them we got it down to like 2.8

Anyway, sorry I just have a little PTSD with caster...:crazy:

Increased, but in the stock range. 2.8-3.2* is the top end of the stock range (I think?) and should work fine for you. A good alignment will help tire wear anyway...
