What’s the widest tyre option for a 38x15 rear wheel?
Currently running 460/85R38 and 420/85R24 on the front.

You will be able to get 520 70 38 & if you want 480 70 24 up front

Have 540s on mine. Definitely wouldn't go wider.

540 is dropping down a size

In radius yes, he's talking about width. Would obviously have to change fronts too...440 in my case..

Widest tyre option is what the question was. 520 70 38 is the widest tyre option for a 15x38 rim. 540 65 38 is equivalent to a 16.9x38 and ideally needs a 16x38 rim. So yes he is talking width, BUT with it being a 4wd, radius is more important

520/70R38 is OK on a 15"x38" rim

You don't need to change your fronts at the same time but 480/70R24 will need a 14" or 15" wide rim.

He should already have a 15x24 rim with the 16.9x24 equivalent already on
