245/75/16 E tires to 265/75/16 E tires

Yes, the recommended rim width (bead to bead) is important, but many mount them
on the OEM 6.5" rim. There is an OEM 7" rim, but not all have that...most common
is the 6.5" rim width

Bead to Bead is the measurement on the 'inside' of the rim...unscrupulous marketing
uses the 'outside' measurement to make it 'seem' wider than it is

That narrower rim width creats more sidewall bendback and that increases the
potential ride quality...but reduces the tire's response characteristics

Of more concern is that the wheel's weight rating vs the new tires higher weight
rating

The wheel spec should be on the wheel somewhere. Suggest the OP check before
purchasing the higher rated tires


This is a picture of my Suburban, which has LT265/75R16E's on 16x10
alloys rated for 3.2K.

Recomended wheel width would benthe biggest concern.

Is there any reason not to change from 245/75/16 E tires to 265/75/16 E tires? I'm considering doing so due to the increase in load capacity from 3042 pounds @80PSI for the 245 tire to 3415 pounds @80PSI for the 265 tire.

I realize that the speedometer will read about 4% slower with the 265 than with the 245 tire.

No reason not to step up a size. I run the 265/16 on my '09 with no ill effects. The speedometer is off by about 1 mph when I'm going 65 mph. Nothing to worry about there either. The tires will cost a little more, but they will carry more, as well as look much better. Go for it.
