Not sure if this pic will work...

Oh, looks like it did I hope... lol
This is my stock wheel I have. I have been looking for specs on it but can't find any. I.e. Backspacing and offset...
I want to put a 37x13.5x17 Toyo Open Country M/T on it... wondering if there will be any problems with doing that...
I do plan to get a lift before... just want to know about wearing problems or fitting the tire to the rim problems... if any. or if I might need some wheel spacers or anything like that. plan to get a 6 inch lift kit, which says it will fit 37x12.5x17
That is off an inch... should I worry about that?
Thanks for your input

factory mega rims are 9.5 wide so no a 13.5 tire will not fit . 11 is max on a stock rim to ride safe without popping off the bead . and you will need at least 1.5 inch spacers . It will be in your best intreast just to get new rims . spacers on a 8 lug truck are $$ and not safe for these bigger trucks .

and FYI all you need to clear 37-12.5-20 is a 4 inch lift . with no rub i speak from experiance

 

I somehow forgot to put this... but the Rims I have (stock ones) are 17x8. Not sure how I forgot to put that lol.
So, what I get from this is no.. I couldn't make this work... lol. What would you recommend (width wise) for a rim to fit the 13.5 width that the Toyo Open Country M/T's come with in a 37" tire? I think I wanna stay with the smaller rim more tire kinda idea.. But... I dunno..
I'm definately set on this tire though.

Are you running 37's on a 4 inch lift then? Does the no rub stay with off-road use? Is it a specific 4" lift kit or will any 4" lift work?

I was hoping to get away with not replacing the rims... but if it's not gonna work then it's not gonna work

Thanks for your help btw RamHunter

 

Depends on your offroad use. Tooling around the farm will be fine. Actually offroading, you're going to rub.

 

So I should maybe stick with the 6" lift idea then?
how about the lift I was looking at, it says it recommends 37x12.5 and the tire I want to get is 37x13.5
Do I need to worry about the 1 inch differance? will that extra inch cause rubbing?

 

it will depend on the rims you get (backspace and offset) iceforever has 35s that are 13.5 wide with just a level and no rub at all with aftermarket wheels

 

+1 mine even rubs just a lil bit offraoding at full lock ( and i could fit 35s under mine easy, running 33.9), but anywhere else no problems, i would go with a 6" lift

 

there is a big difference in stock suspension from a 1500 IFS and 2500 SFA .
A 4" lift on a SFA is the same height as a guy with a 1500 IFS going 6" of lift .

And i have no rub and full articulation , but the truck is not a hill climber its to dam big , but like frog said going around the farm ect it works great .

Op in my opinion i would go 37-12.5 any wider and you will deffinetly need flairs . and with the 37 you will need gears bottom line . heavy truck with heavy tires = go slow need to get gears

 

ya i'm planning to get 4.56 gears after. I currently have 3.73 gears, so... they should get me around okish for a little bit until i upgrade.

The tire I want to get are Toyo Open country M/T's and they only come in 37x13.5x17
I haven't done all the calculations to see if they come in a similar size that are listed as... like... 315/75/17 or something.. (not saying those are 37's just pulled random numbers cause I can't remember what the sizing is called lol)
I'll take a look when I get a chance to.

I do have IFS, what kind of lift should I go with then? I found a top gun customz lift for a 2500 for 6" that is .. reasonably priced. Would that not work?

Thanks for your help guys.

 

You have IFS?? 2wd?? I thought all the megas were sfa... except 2wds...
