Harold:

I had 185R14 Hankooks on my Syncro Westy.  I didn't like it
at all about 60 mph.  I then went to 15" and put on 205/65-15
Nokians.  They were about 8/10" wider.  That change--tire
and width--is the single best improvement I've made.  I
have cruised I-10 in west Texas at 80mph.  (Well, the Subaru
2.5 helped with that....)

I just put the Altimax 205/75-14s on my '81 air-cooled 7-passenger
Vanagon based on the recommendation of Dennis.  I haven't got
any miles on them to make any statements about them.  They
replaced the Hankooks which had been handed down to the '81.
But one thing I liked about their spec is the greater width.

Anyway, I would go with the 195 to get the extra width.  I think
it will make an improvement you will notice.
