Is this going to be a problem??? Help please!

I have a 1994 sport and I am currently running stock tires (235/75/15) and i am wanting to upgrade to a 31x10.50. I know that they will fit on a stock X but am I going to have problems with gears?? I jsut looked at the sticker on the door of the X and it says the axle code is 43, which i believe is a 3.08 gear. Am i going to have a problem with bigger tires?? Any info would be helpful!!!

235/75/15 are ~29" tall.
Only 2" shorter than a 31" (assuming the 31" is actually 31" tall).

if your gearing is 3.08's... well, you'll certainly notice the difference. Although, it shouldn't be huge.

I remember when I swapped out the 235/75/15 on my old Bronco2 for 31's, it was quite the difference. But that was also with a wimpy 2.9L V6 ;)
 






As much as 3.08s suck, I drove my family's 93 for years with those gears and bought my 94 limited which had 3.73s. I never noticed that much of a difference but with the small jump to 31s the 3.08s might leave the tranny jumping gears on any hill climb.

It's always a cheap option to swap over to a pumpkin and a rear 8.8 from a junkyard for a couple hundred bucks instead of paying for a full gear swap for $1,000.

If it was me, I'd run them.
 






thanks man, and yea i decided i am going to run them... and what do you mean get a pumpkin?

he means just replacing the "pig" ie, differential. On the D35's the gearing is setup in the "pumpkin" which is then bolted to the TTB beam.

basically, just swapping out a previously-used dif from a junkyard, instead of the more costly gear install
 






nice. yea that sounds a whole lot cheaper..
what if i know someone that will do the labor for regearing for practilly free.. still junkyard the better choice??

if you know somebody, that knows how to and can properly setup gears, then that is definitely the better choice.

you can get a junkyard axle, but there is always the chance at the junkyard axle will need to be rebuilt.
If you know someone who can and will do the work for free, and do it properly, then go that route instead.
 






Yea so i think that i am going to go ahead and get this mechanic that i know to regrear it for me then... and in your opinion what should i regear it to?
I am going to try to go all the way up to a 33..possibly 34????
 






for 33's I'd go with 4.10's.
 






4.10s are good, 4.56 will have much less regret if you're going to be wheeling it at all, 33s will be your stepping stone to bigger tires.

My truck ran 33s on 4.56 and it has really good power and when I run 35s it can handle those as well.
 






And when i get it regreaed i was thinking about lockers possibly.. Thanks to the X i am going to be broke forever.. Good thing I like Ford haha
