Unsolved wheel mesh not showing up unless i spawn different car with those wheels

i dont know what i did but now when i try to use certain wheels only tthe tires show up only after i spawn the car that has those wheels in a configuration then they show u


for example when i spawn the black car it spawns with no wheels unless i spawn the other car then im able to use those wheels

 

the jbeam for the wheels is likely referring to a flexbody that's only located in the s15 mod. if you export the wheels on their own (assuming they're not already their own mesh), and put them in a common folder, it should work.
