Larger rims usually mean a lower profile tire to retain the same overall tire diameter. Lower profile tires flat a lot more easily as their is less sidewall to flex and absorb road shocks.
There are the most high load capacity tires for 16" wheels which are commonly used with commercial vehicles. Fewer exist for 17" wheels and even fewer for 18" wheels. When you get to 20" wheels you are in light truck territory.
The one advantage of 18" over 17" or 16" is that the rims are wider and better support higher load rated tires.
Check this for yourself by doing a tire search and see what is available for various wheel diameter and width sizes for different load ranges.
A secondary consideration is having a complete tire failure while traveling. Lot easier to find replacement tires at a local shop for the more common wheel sizes.
