As requested from another post: According to the OEM Suzuki Swift shop manual the VIN number is somewhat vague on its break down. To get the detailed info, the dealer will probably have to be consulted. However, the info as indicated in the manual;

My VIN number is: JS2AA34S0K5107169
JS2 - World Manufacturer Number
A - Car Line
A - Series
3 - Engine type
4 - Design Sequence
S - Body type
0 - Check digit
K - Model year
H - 1987
J - 1988
K - 1989
L - 1990
M - 1991 and so on.....
5 - Assembly plant
107169 - Sequencial number

Also according to my OEM manual, GT/GTi models all came with P175/60R14 and ALL Other Models came with P155/70R13

Models covered:
GTi, GT
All Other Models:
GA/GL/GS/GLX

edit: if the ITCS lists the GA as DOHC and 14" wheels, according to the OEM Manual that isn't true. It must be a miss print.
