265/70R17 vs 265/65R17

[bigdon]

Hi guys. I looked all over the place here and it seems everyone only talks about what size tires fit
when they are also talking about lift kits in various amounts, but my 4Runner is bone stock.
I'm buying new tires because mine are almost bald, and I was wondering which you guys would go for.

These are the same size I got from the factory, same ones I have on it right now.

Or, for $1.00 more per tire, I can move up to a tire that is 1-inch taller, which seems like a great deal to me:

I have a 2006 2WD 4Runner SR5 with no lift or mods, so getting the rubber 1/2 an inch closer to the mud flaps and fenders won't matter right?
It stays on the street 100% of the time. Shouldn't be any issues right?
Or am I looking at this all wrong?

if you go taller you'll get slightly worse gas mileage...not horrible just -1 or 2 mpg's. Something to consider as well. But it's up to you. I went big and don't mind at all but that was my choice.

Agreed with the gas mileage. You won't have a problem with the taller tires fitting, but I recommend Michelin's. lol

i just yesterday ordered 265/70/17 Terra grapplers and am getting them installed saturday for some reason they were $1 less than 265/65/17

I just bought my 4Runner last week. Came with 265/70R17 Nitto Terra Grappler's on it. While the tread is low, no rubbing issues. Here's a pic:

I averaged about 18 mpg on the way home all highway averaging around 80-83 MPH (can anyone tell me, is that low or normal for those speeds? Was hoping for more around 20-22mpg hwy). Averaged 17.5 MPG around town on the second tank.

EDIT: FYI, Discount Tire Direct.com has the same Cooper HTP tire in 265/70/r17 for $4 cheaper per tire. The Discount Tire stores around here match Direct's per tire pricing.

Why do you want worse gas mileage? I'd go for better if I had the choice.

I get about the same, 19-21mpg combined but never go above 70mph. If you slow down 5-10 mph and accelerate a lot easier, you'll get way better mileage. Try driving 60-65 in the freeway for a full tank, it's actually very peaceful and the savings in gas is noticeable.

It stays on the street 100% of the time.

I prefer the 70 series tire but I doubt I'd prefer it for 100% pavement.

All the performance advantages seem to apply only to off-pavement operation. Price and availability are often better, though.

I went with Destination A/T 265/70/17 last month, happy. Still need to find the right formula to figure out MPG correctly. Hate to think I lost that much MPG.

Adding 5% to odo mileage should get you very close. If you want better accuracy, you'll have to put in some GPS comparison time.

Thanks, under 16 is the low end of what I expect in city mileage. Still A/T is needed in Southern Oregon, snow and ice at times. previous interstate was 24 MPG. Plus, it looks so good.

It's actually 3.3% to be accurate. If i was going to stay on the street all the time I would go back to 65s. But I wheel all the time so I'm keeping my 70s. The difference on the street is noticable especially since i went up to C-rated LT Duratracs. The weight difference is the biggest thing, it accelerates just a bit slower and has to work just a bit harder.

Ok thanks for the feedback

I know that's what tire calculators say but that doesn't account for any imprecision in the stock setup odometer reading which is inevitable given the variation of tire dimensions within a nominal tire size.

I prefer comparing GPS data (lots) to current odometer readings and, of course, that changes not insignificantly as the tread wears. It's probably hard to get the margin of error below, say, 1/2 a percentage point with any method.

I don't like going by gps data. I'm sure in the flatlands of Nevada it's accurate, but here in Colorado every road has a minimum grade of 1-2% so the gps is usually off by a couple mph. I go by 3.3% because that's the difference in the tire sizes and no matter which size you go with both would wear down. 5% is almost better tho just due to the weight difference between the sizes.

No matter what numbers you go by doesn't really matter in my mind tho. With all the wheeling, taking dogs to the park, pulling trees out of the ground, etc. my gas bill is split between my gas budget and entertainment budget. It makes me feel a lot better about how much I spend in gas.

265x70x17 General Grabber AT2s on stock suspension. No rubbing on full lock, love the stuffed look.

Thanks for the pics xxaarraa.
Helps me picture what the 70's would look like on mine.
Sweet.
