Old Pickup rims on My 98 3.4

I have acquired a set of the old steel rims from a '91 pickup. I've got a set of BFG A/T tires the same size as stock to mount on them. The fellow I bought the rims from said that the wheel nuts on my stock rims wouldn't fit the older rims. He has worked on Toyota pickups for over 20 years, so I believe him, but he is on vacation right now.

What wheel nuts do I need to use with the old rims?

 

are the rims hub or lug centric?

I see no reason to switch over to a different lug unless it's a different size hole size.

Throw them on there and check for clearance and see what interference there might be

 

Will try when I get my new bfg a/t mounted on them, thanks!

And they are the hub..
