backspacing and offset

Where can I find the specs for the backspacing and offset on the stock fake beadlock rims on my TX pro?

thanks, Josh

On your tapemeasure.

Honestly, in my experience, that's been the easiest and most reliable source.

There should be stamping on the rim that rads something like 16x8jj ET0 or something like that. Post that up and we can tell you the backspacing.

Measuring also works but it can be a PITA while the rim is still on the truck.

I know this is an old thread but I'm wondering the same thing? Also what's the ideal offset/back spacing people typically want?

Depends what you are trying to accomplish as far as tire size.

What are the determining factors? Fenders, front bumper, cab mount, UCA and spindles? Are there anymore? What is the order in which the tire will hit and what are the typical fixes? Such as if the tire hits the cab mount, would spacers or spindles fix that? I'd really like to get some 295/75 or 305/75/16's on there without chopping the mount...

That depends on both the height and width of the tire, and the backspacing and width of the wheels. Different combos will hit different things.

Gotchya... so it's pretty much, buy the wheel/tires you want and cut away lol... I'm thinking spindles with the TX pro beadlock style wheels and 295/75 or 305/75/16's should be OK? Maybe 1.5" spacers if needed?

Spacers will make any rubbing you have worse. Those bead lock wheels are 4.5" backspace, if you add that spacer you will essentially have a 3" backspace

Thanks for clarifying that.. I kinda thought that might have been the case but wasn't sure... is that the same for spindles as well?

If those wheels are, in fact, 4.5" BS then they will clear the spindle with a gusset or an after market spindle

Awesome! Just hypotheticlly speaking... if the BSing is 4.5 and barely clears the spindles then a wheel with 5.5 BSing would more than likely hit?

I have the 2011 tx pro wheels and am trying to put 285 75 16s under it, will it rub against any suspension parts like the UCA or anything. I am putting in the 3'' toytech lift with 2'' aal in the back.

You should be alright for UCA clearance.

You won't have to trim the flares but you may have to chop your cab mounts.
