Wheel And Tire Guide For Stock And Lowered Suspensions

This is for the second gen Vios. This should help you in choosing rims.

WHEEL BOLT PATTERN PCD = 4 x 100mm

CENTRE BORE = 54.1mm

OEM wheel sizes, offsets (ET), and tyre sizes (diameter in inches):

14x5, ET45, 175/65/14 = 23.0
15x5.5, ET45, 185/60/15 = 23.7
16x6, ET51, 195/50/16 = 23.7
17x6.5, ET51, 205/45/17 = 24.3
TRD Option 18x7.5, ET42, 215/35/18 = 23.9

With stock suspension, you may safely fit many tyres from 23.0 to 24.3, +/-3%.

Recommended offsets (ET) and tyre widths (mm):

ET35+ = 175-185
ET38-ET40 = 175-195
ET42-ET45 = 195-205
ET45+ = up to 215

Fitment depends on wheel width, offset, and suspension mods.

Staggered fitments:

1. Staggered offsets are common in Japan. These applications even out fitment front to rear and are purely for appearance. Tyre size generally remains constant front to rear. Staggered offsets preclude tyre rotation. Recommended maximum stagger is 10mm.

Example: FR, ET45//RR, ET38

Example: FR, ET42//RR, ET35

2. Staggered tyre widths are less common, especially on front wheel drive cars. These applications even out front to rear fitment. They are not recommended for the track, but as an appearance option they are safe under normal driving conditions. Staggered tyre widths preclude tyre rotation.

Example: FR 205/55/15//RR 225/50/15

Example: FR 205/50/16//RR 215/50/16

Example: FR 205/40/17//RR 215/40/17

3. Wheels spacers are another option to even out fitment front to rear. Maximum recommended rear spacer width is 10mm. Tyre rotation is still possible.

Example: FR, ET42//RR, ET42 with 5-10mm spacer
