If you've seen an NV200 on the road, you are probably familiar with its strikingly tall, narrow shape.
But, the NV200's tires are even narrower. Fitted on the standard model are 185/60R15s, the same size that the 2300 lb Nissan Versa gets. But, completely unladen, the NV200 weighs 3200.
How on earth are such narrow tires safe on a van!?

I guess it depends on their load rating, are they e-rated in that size?
EDIT: from Nissan's site "185/60R15 (high-load) all-season tires"
I found some XL load rated tires in that size that have a 1235 lbs per tire rated limit which puts the grand total to 4940 lbs evenly loaded, given the GVWR of the NV200 is 4751 I'd say that sounds reasonable. Suckers are going to have to have 50 psi in them all the time though.

Ridden in more than a few of these (taxis) - best thing you can say about them is you can charge your phone. Toyota Highlander Hybrid much more comfortable.

This one thing about the Nissan NV200 will shock you. Short answer: load rating. As long as the tires are rated to te NV200's GAWR, there is no problem from a manufacturer's standpoint.

Trying to find this information on Tire rack because it isn't clear on Nissan's website, they say there are no 185/60R15 tires available from them. Strange.

Are 215/75R15s on a 6,000lb van any safer? Cause that's what I have.

Tire load rating also varies with the speed that they're rated at. Most commercial tires are rated at 65 mph and the TRA (Tire and Rim Association) has guidelines for increasing and decreasing load rating based on operational speed as well as recommended inflation pressure changes.
Tires are a very complex beast. I've been doing a lot of tire research lately. :-/

I saw that last year when I saw one in person. How the hell does such a van run on tiny 185's?

a cursory search of a UK spec NV200 shows a smaller tyre size of 175/70 R 14 with a load rating of 95, that corresponds to a safe maximum load of 690kg per corner leading to the the max weight permissible on them being (if evenly balanced) of 2760kg. the UK NV200 has a max payload of 728kg. The Kerb Weight with a 1.5 DCi is 1269kg, which gives a margin of 700kgs on a smaller tyre, so yes it's safe.
if the Kilograms are confusing then multiply by 2.2 to get the figures in lbs.

UK Spec is 175/70 on a 14 inch rim. still has a 1400lb difference between GVWR and max tyre load.

Narrow tires will slide before wider tires. It's not rate for OEs to put narrower tires on tippy vehicles.
Actually, Toyota put skinnies on the MRS relative to the MR2 for the same reason. Better to keep a convertible shiny side up. same for a tippy van.
When Americans look at the new mini and micro vans, we have to remember they have been selling these overseas for a long time.
