I'm about to purchase a new set of tires and I can't decide if I should get the 265/70's or the 75's. I'd like to hear from those that run 265/75's. I'm curious about the following:
Any noticeable power loss?
Noticeable loss in fuel mileage?
Ride quality better of worse?
Handling better of worse?
Performance while towing (I tow ~3500 lbs a few times a year)?

Input based on your personal experience it greatly appreciated.

No noticeable power loss (i only notice a loss when i jumped to 33's), no fuel loss

ride quality is gonna be same if you get the same tire and load range, handling is gonna be the same.

My bfg at's were 31.5 and a 265/70 is roughly 30.6, not that big of a difference, and if you have a gps your gonna find with the 265/75's your speedo will almost be dead on.

I am running the BFG All Terrain in the 265/75 on my 98 4Runner in a Load Range D (8 Ply). Most guys in that size run Load Range E's which are 10 ply tires. I personally would go with a Load Range C tire if you can find it in the 75 series because your ride quality will be the best compromise for towing and not towing.

Power loss...maybe a little bit, I did not notice a seat of the pants difference with the 75 series.

I think I calculated an average loss of .5 mpg going from the 5 ply P-metric tire to the 8 ply LRD tire in the larger size so I would say no real noticeable loss in fuel mileage for me.

Ride quality is a bit stiffer with the LRD tire, the LRE tires are designed for 1 ton trucks towing practically anything so they are going to be pretty unforgiving on a lighter weight 4Runner.

Handling is probably a little better for me. It leans a little less on off-ramp corners in my case. I also had a pair of Bridgestone Dueler H/T tires before which are pretty inferior to the BFG's in rubber softness and tread design.

I would say the looks of the 75's and the slight off-road advantage out-weighs the negatives of a heavier tire for most situations...if you tow 3500 occasionally I would recommend any size in the Load Range C if you can get it...I have only towed a 6x12 enclosed trailer twice on my 4Runner and it seemed equally as slow with both size tires...if you throw a lot of hills into the equation you will probably notice an advantage on the 70 series.

It's an easy size for the 4runner. More meat without the lift issues. You won't notice much difference. I tow with 33"s and it is a bit of a headache. Under 65mph in 3rd and the power band drops pretty good.

I like my 75's, my gas milage has'nt changed that much.

You could split the differance and get 275/70/16,They fill out the wheel well nice.

From going from 265/70's to 275/70,milage is about the same,acceleration a tad less,braking a tad less(unless you have the tundra brake upgrade),handling the same.

Although when you go to the 75 series there are more choices in turck grade tires,ie load ratings.

You may encounter slight rubbing up front on the front mudflaps if you care to run them if you step up the size to the 265/75/16. This is a concern of mine as I have no fender flares and the spray from moisture coats my body sides thus I must run front mudflaps to minimize it. Seems everyone out here waters the streets when they water the median landscaping....

I noticed no change in power or fuel economy in doing so. The ride quality is better perhaps "stiffer" and less softness when hitting potholes or railroad tracks.

97ltd4x4s idea is a sound one as well. You would get a slightly taller sidewall and keep the tread width identical while filling out the wheel well somewhat better.

This is a topic that is discussed almost daily, certainly weekly on this forum and t4r. Have a tire dealer show you the 2 sizes in an identical tire choice side by side and be sure they fit properly.

I have people constantly trying to argue with me that 265/75s do not rub but for me they do and I am now lifted slightly in front with 881 springs and more so in the rear with 891s.(old man emu Prado designed springs)

i went from 70s to 75s didn't notice a change in anything but they do look better and fill out the wheel well much better
