With larger tires the truck WILL lose power, if auto-trans you may not notice it but with a manual you will need to shift to a lower gear to do the things you used to do in a higher gear... just the facts, I've lived it !
I'm well aware of the concept and benefits of regearing. When we did 1 tons and 39.5s on my 4runner with dual cases we regeared to 5.38s. When we installed a blower on an older cobra we regeared to 3.73s to aid in acceleration at the track.
The size difference in going from 245s to 265s is minimal. I already have 265s so I'm completely used to the truck now.
It's only 3.5% according to a calculator. According to my gps my odometer is 3.1% off, so it's a pretty accurate calculation.
To put the truck back to a stock power level would require a regear to just 3.90s. Since I doubt those exist for the front end, a 4.10 swap is more logical. That said, the 600-700 in parts to gain the tiny amount of lost power on truck for a 16 year old is just money wasted. If we are talking much heavier tires, or 35s, sure I'd go for it.
Hell according to discount the bfgs on my truck weigh in at 53lbs each. The tires going on my truck weigh in at 40. That's a pretty significant difference.
Between the weight loss of my current tire, and the truly minimal size difference, I'll be fine.
