265/70R17 vs. 275/65R17

[Igor]

What would be advantages and disadvantages of both sizes?
17" Sport wheel. No suspension mods...
Currently have stock 255/65R17 Duelers.
Street/off-road 80/20. At least for now.

Thanks in advance...

I feel 265/70/17 is a very common size and more choices. That’s just observation when I was looking.

That's what I am trying to understand: advantages and disadvantages wider vs. taller

Wider tires generally speaking can give you more traction. Taller tires can give you the possibility of better MPG due to lower rpm at set speed. Between these two sizes I would go the 265/70-17 because it is more common and readily available and you won't see much difference between that to a 275/65-17.

I should add that I have the 265/70-17 and ir does just fine. No major issues what so ever and my MPG didnt drop much with just the tires and lift combine. I got that loss back with a tune and i figure you already got one of those.

I recently swapped same size you have for 265-70r and was going to go 75r but the price difference for the same tire was over $70 each, simply because 75r is an 'odd' size and they don't produce as many. keep that in mind when shopping. value>less than an inch in size was my choice.

I went with 265/70R17 because I have a specific tire in mind. However when doing comparisons I didn't find much difference in the ratings on a 75 series, but there are fewer options, and they cost quite a bit more than a 70 series. I have Toyo open Country AT 2 AW P265/70R17 with a 2.5" BDS front end lift. But I also do a fair bit of gravel and back country roads, and spend a lot of time in the mountains. I wanted a tire that will hold up well, give me good traction on highway and off road, and had to be "winter" rated as those are legally required here in the mountains from Oct1 - April 30th. With 30" of snow forecast for the next 4 days - I'll soon know how well they do !

good point about tire brand. I got the grabber ATX, and the 75r version is an LT tire, which is also what makes it more expensive. the don't offer a P version in that specific tire size.

Sorry to go off topic. Why did you go with the AT 2’s vs the AT 3’s?

Taller and narrower will be better in winter driving, mud, loose gravel and it will roll over obstacles better.
