No, 285 is the width.

How wide are the 18" wheels, since 285 is the width, not the height?

Not sure how wide they are .my bad I've always gone by the width
265 = 31
285 = 33

@Radwop 265 and 285 are the width, not the height. They aren't 31" or 33". 265 is 10.4", not 31". 285 is 11.2", not 35"

265 and 285 are the width, measured in millimeters (metric). The next number is the aspect ratio, meaning a percentage of the width. So, 285/70 and 285/75 are the same width and different heights, because one is 70% of 285mm and the other is 75% of 285mm. Get it?

Thanks so Im asking the wrong question. Will 33" tires fit on the outer banks without a lift ?

Outer Banks comes with 18x7.5. The stock tires are 32" tall.

A 285mm width tire will fit a 7.5" wide wheel. One inch taller than stock will fit your vehicle.

So, you can do a 265/70/18 or a 285/65/18. Remember, relative to width, the second number (aspect ratio) is just as important as the first (width). To find tire height you take the aspect ratio of the width (70% of 265mm), which gives you the sidewall height. Multiply that by two, because there is a sidewall above and below the center of the wheel (axle) and add the wheel height. So, a 265/70/18E tire is: 265mm * .70 = 7.3. You multiply that by two (7.3 * 2 = 14.6) + 18 = 32.6. So, a 265/70/18 should be about 32.5" tall, but all manufacturers have slight differences. You know it is 265mm wide, which is 10.4". A 265/70/18 is a 32.5 x 10.5 x 18 tire.

Personally, the difference in height is negligible and the performance is tread dependent. The only reason(s) to change your tire is tread performance, or looks. I would buy a 265/70/18 BFG AT KO2. It's the best tire ever made on the planet (and most others) and it's worth every penny, no matter how much they cost. And yeah, they'll fit.

Any time you hear/read someone talking about 255, 265, 285, 305, etc. and talking about tire size (height), you'll know they don't really know what they are talking about unless they include the aspect ratio (second number). You can't tell the height if you only know the width.

So for size 285/65R18 I am planning to get these tires which have a higher speed rating.
