Your 235/75R15 is less than 29" tall, so there is going to be about a 2" diff. in tire height. Your speedo reading of 65MPH will actually be about 69MPH, without being re-calibrated. Your mileage will depend on your gearing, because that will be affected. A 265/75R15 is virtually the same size as a 31/10.50 -R15, and will give you more tire choices. I agree, the bigger tires do look better.

I've had 31x10.50 for almost 7 years and have never had a problem with them. They have good traction and do fine on or off road. I am, however, going to get 33x12.50 in the near future. My tires are cooper discoverer by the way.
Thanks for the input guys. I had a kid in a Jeep with 31/10.50s hit me once right after a rain and he tried to pass it off as the tires fault. Been shy of them ever since. He hit me so hard, he cut my bumper in two!

That would be driver error, not tire fault. The only way I could see it as tire fault is if they were bald tires or flat. A 31X10.50 is not that big of a tire.I had a Wrangler with 32X11.50's and it stopped fine. Heck the Rubicon's come stock with a metric tire that is pretty much a 32" tire.
