Actually, it works the other way around.  After 20+ years of off road racing (Baja 500 - 1000, etc.), I can assure you that the higher profile of the tire helps protect the rim from damage.  

Just look at the rim/tire combinations that are run by serious off roaders.  Off course, they also use bead locks...

Cheers, 

Jeff

Good advice. I have the alloy 14-inchers from VW and do wonder how tough they are  that said, I've hammered them quite a lot and they're still straight.

I believe that the larger the wheel is, the more one can punish them without failure, and I suspect this is true of the alloys as well. Not sure which way I'll go when upping to 16"...
