I agree with the post above, though I have found some differences. I did have slightly better gas milage with the 235s, I found I was a little less stable through turns at speeds I shouldn't have been driving. With the 265's, the truck handles like a go cart. Again these trucks are not designed to be raced around in but the bigger footprint feels more stable. I also used 4wd less last winter and use it less on wet grass. Not sure if it's the larger tire print or what??? If I were strictly looking for gas savings, I would stick with the 235's they weigh less and give the truck have a bit more get up and go and I found no drawbacks to them at all. I just ended up getting these 265's for the same price as the 235's brand new and tried them out. I'm not sure which tire I'll put on next time around.
If I had an 06+ 4cylinder Tacoma again, which will prob be the replacement for my current truck when the time comes (I really need the back seat space again) I wouldn't even dream of getting the 265's without a re-gear. I hated those tires on my 08. Killed the gas milage, killed the throttle response. I have 4.30's in my current truck and the 08 had 4.10's and what a huge difference that made. So on the newer trucks I would only get the 235's and they look really nice on an access cab.
Sorry I don't have pictures to post.
