265 MM
10.43 inches
10.43 Inches (rounded to two decimal places).
A ski boot size of 265mm typically corresponds to a men's size 25.5 or a women's size 25.0 in the Mondopoint sizing system, which is commonly used for ski boots. This measurement indicates the length of the foot in millimeters. It's important to try on ski boots, as fit can vary between brands and models.
It is not necessarily any taller, there are other factors to consider, mainly aspect ratio (if the tire is a 60, 65 or 70 )
Actually the cross section width, 265mm , is about 10.5". It may fit but I would check with a tire dealer. I seem to think the the width of the rim has to be a little bit smaller than 1/2 " for the tire to be safely mounted.
To determine if a 265/70R17 tire will fit on a 17x9 rim, you need to consider the tire's width and aspect ratio. The 265mm width is compatible with a 9-inch rim, as the typical range for a 265 tire is 8.5 to 10.5 inches in rim width. However, ensure that the overall diameter of the tire does not cause clearance issues with your vehicle's suspension and bodywork. Always consult your vehicle's specifications or a professional for the best fit.
