    Hi,
    anybody have access to actual tire size charts ? I've used all the "tire calculators".....but they all seem to go off some master data base, and the bottom line in my experience is that the actual size given is a good inch to inch and a half big (i.e, 33's are actually 32", but the specs say 33, etc....). Hard to gauge what you can run when you can't even rely on your tape measure !

    I have LT255-70-16's, which are supposed to be just over 30", but are just under 29" in reality.

    My 32" tires are just over 31 1/2" if I take a tape to them... I think that is normal to round up or to closest whole number...

    Mine are 265/75-16"

    Correct. Tire manufactures round up. A 32.5" tire is clasified as a 33" tire. Same with a 33.2" tire. A 33.4" tire is considered a 34", etc.

    Do you have a brand in mind? Most of the tire manufacturers have pdf files of the tires that list the overall diameter on their websites.
