Not only is that not the correct size, for any highway travel it is
dangerous.

The two original size tires are either a 185/80-14, load range C or D or the
reinforced 205/70-14. The 185/80's are usually close to 25.75" diameter, the
205/70 just under 25.5". The 205/70 has a load index of 97, ~1570 lbs. The
185/80 can be as high as 102, 1,875 lbs. Your tire is only a load index of
89, 1,290 lbs. When a p-metric tire is used for an LT application, you need
to de-rate it by 10%. That brings you down to 1161. To make matters worse,
your tire is probably not rated to carry sufficient air pressure for the
proper handling balance of the van. The 205/70's should be inflated to 41
rear, 36 front. Are you tires rated to 44 psi? Time for new shoes quick.
