Adding tires from other mods

I have a mod with some awesome tires and they would look really cool on the D Series. If possible, how could i do that. The mod they are currently on does not work and this is a big reason why i also want them.

 

if the tired are from a mod off of the beamng site it should be ok if you get permission to use them. Make sure to give credit to the author. If the mod your getting the tires off of are from a Russian site then NO.

 

why is it no? just so long as he credits them i see no reason why not.

 

I got the mod from this site
