Nope sorry they are the same, depending on the manufacturer the 2 sizes bounce back and forth which is taller, but its usually only about .1 of an inch. I don't see what running a 265/75 front and 235/85 rear would hurt even on a 4x4, the possible difference in size is so small it wouldn't be any different than tread levels or a few tire PSI. My truck is a 2x but I run 265/75 ATs on the front and 235/85 MTs on the rear and heightwise it's impossible to tell.

Didn't look to see what yours is, but I ran 31x10.5 on my 4x4 F150 with the alloy rims for 5 years and just put up with the rubbing. You should be fine, they never damaged anything more than the factory 235/75r15s and I wheel that truck (as much as you can a truck that height) on an almost weekly basis.

Ya my truck is 87 f150 4-4. Any reason why the alloy rims are deeper dished that the steel wheels. I noticed that when my front 4-4 centercap sticks out like sn inch more than it should when i have alloy rims on

Just depends on how you use your truck and how tall your wanting to go, a 315/75 would be about a 35x12.5 tire. If you just want a bit more height over your 235/85s you could pick a 285/75 which is about a 33x11.50, or pick a 305/70 which is about a 33x12.50. I really don't know if you could even fit a 315/75 under your truck without a lift, not sure on the 4x4 1tons, I've never owned one.
For you the 285/75 might be the better choice since you own a dually. There might be some less common size that might be the same height but narrower I'm not sure, thats just the usual easy to find sizes that you can get almost any tread pattern in. I friggin hate metric sizes such a pain in the *** compared to the old inch sized tires.

But to be honest I'm not sure really, I never swapped rims on that truck when I had it, I got rid of it MANY years ago. A tired 300I6, 3.08 gearing and an E4OD was a terrible combination for bigger tires and doing pretty much anything other than going slow on flat level ground. I parked it when I got my Bronco with a 351W and it's what I lifted and put bigger tires & different wheels on and never looked back.

I got a 300 with 4spd and 355 gears and it has no gett up and go what so ever. Doesnt help either running on 5 of 6 cyls. It seemed to go a little better with my stock tires. The truck dont want to move to fast no matter how you push it its hard enough getting to right speed limit dunno why its so slow dads 300 with 5spd is a lot more gitty up than mine also with 355s

I believe the factory had issued the trucks with an xl spec on the tire which is for extra load. Basically what I believe is similar to a LT tire(light truck). I hope you arent going to try load range c tires or passenger spec ones. Trucks need a stiffer tire for hauling.

Ok guys so i put tires that were 3 sizes bigger. from 235 to 265/75r16 ya they seem the same height but arent really. slightly taller and inch wider. i know this because i put procomp xtreme all terrain tires on my e99 dually. now the 235's didnt rub on the front inner wheel well but the 265's do just ever so slightly. and the duals DO NOT rub or flex under weight. now i havent had a full load in her yet but soon will and will see if i need to add a small spacer like 1/4in bt really no bigger. as of now i can barely fit my finger tips between them but like i said they are stiff tires with no flex in the sidewall at all. i hope this helps a little with all of your projects.

The aluminum rims are also thicker then the steel ones which might be here you notice the center cap sticking out a bit farther. I think the backspacing is the same just the middle of the rim is thicker

265s in place of 236s id a bit much with out a spacer. I would keep a CLOSE eye to make sure they dont touch wheel loaded up.
Someone brought up my wheel spacers
I have 2 pair. One from ARROWCRAFT and one from Wheelspacer.com
They are IDENTICAL billet steel with the hubcentric ring. The ONLY difference was the price.
Arrowcraft $200
Wheelspacer.com $320
DO NOT trust aluminum spacers on these big heavy trucks. They need to be Billet STEEL and HUBCENTRIC

Ya never said it was. but also if its dropped from about a foot high to the ground with the weight of a one ton truck and didnt budge then its a start. oh and if the truck didnt buge it from a drop then going down the road without a load wont do too much damage unless i rock the suspension good by hittin some good potholes. loaded though i know they will touch but dont wanna get too big of a spacer either
