great info PaulF thank you.
So if I run 30x10 tires that would clear me of all potential rubbing?
So much conflicting information out there hard for me with my lack of knowledge to get a clear yes or no with specific tire and wheel combinations
There is no magic "one size fits all" answer.
First off, when I say 30X10, I mean true 30X10. You will find that 30" tires vary from 28" to 31" and 32" tires vary from 30" to 33" inches. That is why you see one post that says 32's fit fine and another that says that 32's rub like hell on an X.
Next, an X+Y tire offset is completely meaningless. There are 5+2 wheels that range anywhere from +40 to +10 offset. That is over 1" difference so again, you will see one post that says 5+2 wheels are fine and another that says they are not. I will NEVER use X+Y type offset, I will always use +XXmm offset.
True 30X10X15 on +35 to +50 offset wheels will not rub on an X (front or rear).
True 31X10's with a rounded profile
on +35 or greater offset wheels will most likely never rub but it will depend on the profile. If they do rub, it will be very slight.
True 32X10's will almost always rub under left turn/compression.
If you run aftermarket skids that hang off the front, you may have to trim them, even with 30's.
