Bigger tires on my 2000 Suburban?

    The sticker on my 2000 Suburban calls for P265/70R16 tire size.
    Question:
    Can I put a set of Firestone Wilderness P265/75R16-114S-M/S on it without a problem?

    Is that 75R16 vs the prescribed 70R16 too much difference?

    Thanx

    replied to other post but only adds 1 inch and makes it 31.6, basically a 32" tire. Shouldn't be an issue but I'm sure others have tried it and will now for sure

    The difference between an aspect ratio (that is what the 70 and 75 refer to, or 60, 50, 40, etc, it is the percetage of the sidewall height) of 75 and 70 is not that great as to be a concern.

    In the old days you would replace a 78 series tire with a 70 series to increase the width of the tread and shorten the sidewall. You are going the other way and slightly decreasing tread width for a little more sidewall height.

    the tire width will stay the same 265 is the width 70 is the sidewall aspect ratio (70 percent of the tire width) and 16 is the rim diameter

    you will be fine running that tire
