    Default 2 Different tyre sizes on 4X4

    If 2 different tyre set sizes are used on a 4X4, same size front and same size back, I assume the drive train will be under strain and damage may occur if 4X4 is selected. Will it cause same damage when driving in 2X4?

    Depends on what vehicle it is. Older vehicles I believe it shouldn't be an issue, but newer ones, might still wreak havoc with ABS and Traction control.

    Vehicle 'thinks' the two smaller wheels are spinning...

    I think we will be better able to advise with more details.

    What vehicle?
    How big is the difference?

    Probably not the best thing to do, but might be ok depending on the above.

    Shouldn't be an issue in 4x2. In 4x4, if you have a centre diff it should also be okay. If you don't have a centre diff (like most bakkies) then you will get wind-up and put strain on your drivetrain. Definitely not recommended.

    Having said the above, for the workable otions I would only do this in an emergency to get to the next place where you can have the tyres fixed.

    Even if there is a centre differential, 2 different tyre sizes front and back aren't good for that either in the long run.

    Agreed, emergency only if you have no other choice.
