I have an opprtunity to purchase a set of custom wheels that are off of a GL450. Does anyone know if these would fit a 99 G500? My other option is to make the drive and just try one but didnt want to go through the hassle if somone already knows the answer. They are 18" which I already have and they have 265/70/18 tires on them. Just a great deal so I thought I would ask! Thank you!
