I second this. The math doesn't lie. However, different manufacturers will have different actual measurements for the tires so you're best off looking on the manufacturer's site to check if they have the actual dimensions. They'll just more or less "classify" the tire as a 265/75/15. It might be a little bigger or smaller.

it's official outside diameter is 30.7"x10.5". The only place it rubbed was the outer front fender/bumper and it seems its the width that made it do so. They look good now though and I'm happy I went bigger than oem.

I was under the impression that 265s were 32s. Guess I've been wrong for quite awhile haha
What are 32s in metric then? 285s? Because I always thought that 285s were 33s... Sooo confused now!

he's on a 15" wheel vs the 16" wheel you're thinking about.

265 is the tread width in millimeters. The /75 or whatever number it may be is a ratio of the tread with to sidewall height. A 265 is pretty close to a 10.50 width wise.

Nice link and a great place to buy tires. I've purchased my last 4 sets of tires from them. I've driven out there each time to pick them up.

I've read a lot of great things about the tire rack. Never used them because I'm only about 40 minutes from summit racing and my cousin has worked at a tire and repair shop for about 25 years.

I'm a little farther than that from Tire Rack. I want to say South Bend is about an hour and a half away from me, give or take a little. I actually bought my wheels from Summit. Summit is another great company to deal with. They have incredible customer service. When I got my wheels, one of them was stamped poorly and looked drastically different from my other 4. I called them about it, they told me to sent it back on their dime and they'd be sending me another one. They've also got some crazy customer service hours so they can service the whole country conveniently.
