Didn't you go through all this in your other post SOA vs SUA ??
have you done anything regarding your SOA setup and is that what your going to do ?
GLTHFJ60 , you seem to be a little undecided on what you want to do , your thinking of going a 38 x 14.5 , you wont get that in like others before me have mentioned , ive got some 37 x 12.5 x 15 MTR's and they fit great but anything wider will not tuck in.
If your that concerned about 1/2" extra diff clearance with a 38" from a 37" tyre ,
what you do is when you do your your SOA if thats going to happen rotate your pumpkins upwards to the sky and you will be able to shave 1" of your pumkins which is really 2 inches of diameter , and then you've got under diff clearance that equals a 39" tyre !! , and you've saved money buying smaller tyres.
In other words " there is more than one way to skin a cat " ,
the other thing i remember you mentioned on another thread somewhere that your working to a reasonably tight budget ,
so what you can do is cut corners to save money on things like
* new springs vs good second hand springs ??
* 35" - 37" tyres vs 40" tyres , the initial cost of the smaller tyres will save you money , but the other thing is if you go too big and you haven't sorted out things like cv's , axles , ratios and ofcourse a motor that will turn them ,
it will cost you s*** loads more money in the long run from breaking things , so unless you going to sort all those issues out first dont bother .
And what you will have if you dont sort all that out is a nice 60 on 40" tyres , that you cant take off road cause you dont want to cut the guards ,
so that means that you will have no articulation ,
you will be s*** scared that you may break something because everything is too weak around those tyres , and also you wont get anywhere because your under powered .
I suggest you work out what type dream rig you want and work towards that in the right order of build up ,in this situation money is no object,
otherwise be realsitic and work to get the best trail rig out of the money you have to spend , which is probably what 99% of people including myself on this forum do and slowly chip away.
See how you go , cheers
