I'll give my input. I've got a 94 Splash 4.0 2wd auto with 3.08s out back. I put new wheels and tires on back in September and went from a 15x7 stock wheel with 235/70s to a 15x8 eagle alloy wheel with 235/75 Toyo at2s and can tell a HUGE difference. Before these new wheels and 235/75s power wasn't great, but it's really not that great now. I went from probably 17-18 mpg to about 15. I cruise mostly around 40-55 on roads around where I live and can't stay in overdrive. If I'm on the interstate, I have a ton of trouble getting from say 60-70 mph. I have to get around 2500 rpms to pass. I'm constantly on the throttle to maintain speed and to get anywhere. I've strongly considered regearing to maybe a 3.73 or lower because I hate driving it everyday. I'd throw the stocks back on if I could afford another set of tires. . From my experience, I definitely wouldn't go with anything over a 235/75 without regearing. The case may be different if you have a manual transmission and a 4.0, but with my auto I'm not a fan and don't suggest a big tire. I couldn't even imagine running a 33 or 35, shoot even a 30x9.5 would be too much or a 31. Not sure what my advice is worth to you, but there's my own two cents. Not saying it couldn't be driven, but I wouldn't recommend even a 30.
