Man, I remember wheeling the Rubicon, Barret Lake, and Fordyce back in the 80s with my longbed 82 Yota on 33's......and that was considered a BIG tire. LOL. I couldn't imagine trying to wheel a 40" tire through any of those trails. There are spots that you can't even get an original Bronco through because it's too wide. I know there have been guys on the trails in fullsize rigs runnin large tires like that, but thier rigs look like they've been put through a rock tumbler, and to me, that's no fun. What good is wheelin a big rig if you're just gonna smash the body to bits. I always preferred driver ability over smashing the pedal and getting through it at all costs. And that's what alot of the fullsize rigs have to do.....to a certain extent anyway.

 

i think that they should be at least 21 inches wide

 

iirc they are 54x21

 

on the link on the first page they say that they a 19.5x54x20

 

i myself am thinking of getting the 54's for my dodge, and a buddy of mine is for sure getting a set for his new 6.0 f-350. the only thing im worried about is price on the tires and the extra 4-6" of lift im going to need. btw, will these also be DOT approved.

 

Well, good luck fitting them.....and yes, the 54's are DOT approved like all of the other Boggers.

 

what kind of problems will i have trying to fit these? im working on another 6-8" lift, and my truck will clear 42's already and 44's will clear the fenders, but i need rims with less backspacing cause they will scrub up front. i figure that my buddy will be able to clear no problem. hes ordering 18" of air lift, and then somthing like 6" of body/spacers/blocks.

 

you could always just build a four link for your truck and the run some stiff coilovers. But i would get some good sway bars because that heavy cummins would get to rockin that high up

 

im thinking of getting air springs for the rest of the lift. a buddy of mine did a 4" air lift, and loves it. he says it rides and drives like a dream, so i was thinking of going that route on top of what i have already.

 

Hmm....all that lift just sounds scary to me.....any kind of measurable perfromance will go down the tubes. I take it these trucks are just for show? You are going to need one heck of a lot of axle gear and a 1 ton driveline with a Cummins won't begin to deal with 54" Boggers in an offroad environment. To each his own, I suppose.

IMO, 54's are just way too big for the average rig....I think they will best be suited to competition bogging mobiles or low slung buggies with 2.5 ton drivelines.

And without trying to come off sarcastic-like, I don't profess to know exactly what is required in the way off lift and wheels to make 54's fit on a Ram....the simple answer would be: A lot of everything!

 

yea, there alot of measuring/fitting/refitting, thats gonna go into it. mines not a "show truck", it will get drove a few times a week, and my buddies will get drove daily. im still not 100% if i want to invest all that time and money yet. mines nice the way it is, and 54's will make it almost impossible to drive on the road. on the other hand, my buddy just walked into $4.7 million, so hes got money, time, and everything on hand to do whatever may need to be done to his. im not sure about jumping to 54's yet, but after i get out of school and another ride for work, they may be on the way. im gonna see how the work out for my friend.

 

I've got 44" boggers on my bush buggy {GM 1ton} with the D60 and 14bolt I would go much bigger or heavier if you're gonna make any sort of power. My stub shafts are upgraded to 35 spline and they're cryo'd. with detroits front and rear. I would worry all the time about breakage if they were any bigger.

 

You're gonna need the Rockwells. Only other option that would have a chance of surviving would be D80 rear and Dynatrac D80 front with all of the upgrades you can think of. If you ask me you are gonna need alot to make those fit. Besides that you are gonna have one heck of a time getting your driveshaft angles manageable.
