bigger tires on a superduty

No, I do not feel like searching on google, or posting on some diesel website to find this out.

I have the stock size on my 2001 and was thinking about taller tires next time. What will fit on the 4x4 version without any lifting?

285/75/16 fit no problem. I would think a 305 would be a good fit too. Given how close my 285s are I think 315s may tag the inner fenders especially on a diesel with a little sag to the front springs.

285s

33's fit on my bronco with sagging springs, and a little bumper trimming. My father in law has 35's on his 03...

About 7% based on the difference in diameter from the stock 265s but I never had stock tires on the truck. 7% on the v10 is about 200 rpms in 5th gear. The big thing to take note of us I have 16x8 wheels now. When I was running the stock 16x7 wheels with the 285 tires it was tougher to run high pressure and get eventire wear across the tires. With the wider wheel I run 55psi in all 4 tires all the time without issue and very even wear.

For me the difference between 48psi and 55psi is about 1mpg fuel economy

I take it you went to a 16x8" rim on yours to get the tire to run flat on the road again?

were any of the superduties 16x8?

Yeah I swapped wheels after I got the tires. I didn't need to but I wanted to and so far it has worked out better for tire wear and pressure.

I think all super duty wheels were 16x7 from 99-04

I'd go with a 285x75-16
The 305's fit but they are a bit wide for the stock wheel.

i don't think chris understands tire sizes or what they mean.

a 195/75 is more akin to a compact car tire dude.

I think he meant the 195/75 thing as a joke.

And go 285, a co worker of mine is running that size on his 02. He dropped down from 305s, and although it's not that much of a size difference, people who are sick in the head like him and I think they fit the truck much better

Reading comprehension and sarcasm don't seem to be some peoples thing on here I noticed.

The tread pattern on tires come into play for fitment as well. I could run BFG Mud Terrains in 33x12.5x15 on my 86 and they didn't rub, I tried a set of Good Year Wranglers in the same size and they rubbed like crazy on the front due to the tread pattern. Both sets of tires had about 80% tread left when I put them on. I worked at a tire shop so I had access to lots of tires Backspacing on the wheels will affect clearance as well. http://www.rimsntires.com/specs.jsp Good place to start to figure out what should fit.

Bronco Info: none right now.. should be picking up some more soon
i can run 35" tires (i think that is a 315 tire) on my 97 powerstroke 4x4 (with sagging front springs) and rub very little. I went down to a 285 due to $$. I also run treadwright.com tires on the back. no complaints at all and i have over 10k on them.
