Hi guys, im looking at a set of after market wheels and tires a guy had on a 98 2500 dodge, just curious if there going to bolt right on or if will need a spacer and or different studs? Thanks in advance!

 

I am uncertain which year Dodge switched from lug-centric conical-seat wheels to hub-centric flat-faced wheels.

If these wheels have conical lug-nut seats, then yes, the bolt-pattern should fit and the nuts should work --- PROVIDING there is not any negative offset that makes the rim contact something, usually the caliper or tie-rod.

If the wheels in question are pot-metal, commonly called aluminum, then I would not have them as a gift --- but that's just me.

 

You can always test fit one on the front and then the rear to check clearance.

 

The only way to know for sure.
Aftermarket wheels may be different offset than the stockers.

 

And being "pot metal" aka "Aluminum" the rims will be thicker in stepped areas for strength. So there maybe, as suggested, clearance issues with the calipers and other front end components.
