Here you go, 245/75/16 Dunlop's on 16x7 Tacoma wheels. Ran these for a couple of months and loved the extra power and mileage. I was running a 3" lift with these as well and while they looked small they weren't that bad.
It's only a ~3/4" difference in width, which is about an 8% difference. I doubt you'd even notice, especially with the price difference between the 245 versus the 265.
