wheel offset

the offset of the rim/alloy is the amount of distance from center of rim/alloy.
in other words how much the rim/alloy goes in or out of the body.:D

see the picture below.

a + offset rim will reduce the standard track length of the jeep gypsy. (mostly sock rims are + offset ones in almost all vehicles)

& a - offset rim will increase the track length.

but the increased track can also result in the suspension (in IFS) & bearings (in rigid & IFS) issues.

some times the increased track limits the articulation too.

example. armada/bolero rear wheel arch. (even thar ):Frustrati

in stock form the tyre goes in the body tub under heavy articulation (pic 1, 2) , but when the track increases the tyre directly touches the wheel arch thus limiting articulation (pic 3).
