Hi all, a while ago I bought a set of Mercedes 15" SLK alloy wheels, intending to fit them to my 1998 T4 Caravelle. Luckily I subsequently found out that wheels fitted to buses have different weight bearing capacities to cars. It sounds obvious to me now but I was ignorant of this before. What would like to know from you experts out there is; how do I found out what the load bearing is on my particular wheels and, if they are unsuitable, what i need to know in order to buy the correct wheels??
