According to the website above, the width of a Suzuki Maruti Gypsy is 1540mm. However, there is no mention of the front or rear wheel tracks.
Is there a difference? Is the rear wider, or the front wider, or the same?
Most vehicles created with a single pair of wheels up front and a single set of wheels in the rear have the same wheel track (I could think of a few, like some Porsches have different wheel tracks ... and if a vehicle with dual rear tires, like a Silverado 3500 or Ford F350 have different front to rear wheel tracks). If they don't specify there's a difference, then it is a good assumption they are the same front/rear.
Well, a quick google search (enter link description here) gives wikipedia as the first link which has lots of information and states exactly what you look for:
Front track 1300mm
Rear track 1310mm
So, rear track is larger than front, a possibility mentioned by @Paulster2.
These values are based on the standard wheeel/tire combination, if an owner has changed wheels/tires then the track dimensions may be different.
An easy way to check is to use a piece of angle iron with two points on arms and a ruler.
