The stock Jimny rims (not alloy) are marked 15×5½ JJ 3007/1/55JK 010 and have 5 bolts. This translates to:

– 15 = rim diameter in inches (38.1 cm)
– 5½ = rim width in inches (13.97 cm)
– JJ = rim flange shape

Other info (obtained, not calculated: PCD 5×139.7, center bore 108.4, offset 5). Other Jimnys have it like this: 15 x 5½ JJ 3008/5/55JK 026, 15 x 5½ JJ 3002/1/55JK 11, 15 x 5½ JJ 3007/3/55JK 01, 15 x 5½ JJ 3004/2/55JK 2. Now, the “3007/1/55JK 010” remains a mystery.

The “30” (or “3.0”) in the beginning seems to be constant; the next two digits might be the manufacturing year (my Jimny was manufactured in 2007 and matches the “07”, while 02,08,07,04 also look like calendar years). The next digit (1,5,1,3,2) might be the manufacturing month. 55JK is also constant, while the last digits are also unknown. If anyone knows more about their meaning, please do speak.

Manufacturers seem to match the Jimny stock rim to 15×5½ 5×139.7/108.4 ET25 while others list it in the same way as the rims for Vitara 1st generation, with ET0. The center hole is 108.4 milimeters (110 works).

The tires are BFG A/T KO and are coded with 215/75R15 100/97S load C. This means the tire is 215 mm wide (widest point between outer edges), 75 is the percentage of the “aspect ratio” extracted from the width (that means the tire has a height of 161.25 mm), the R stands for Radial and the 15 is the rim diameter in inches. 100/97 should be the load and speed index; 100 means the load index is 800 kg (matches what’s written on the side of the tire), while 97 … good question. A “C” load rating means the tire is 6-ply.

The manufacturer lists this tire as LT215/75R15/C, which would match the “Light Truck” designation, and a load rating of 100 (so the whole car could take 4×800= 3200 kg).
