Wheel fitment

Postby TOYO-GT-T » Wed Jul 04, 2012 10:10 pm

I am not too good at offset and tyre size....

Found a set of rims of trademe.

4x100
Offset - seller not sure,but believes its 35 or 45
Tyre size is 195/45/16

Have been trying to use this guide to assist, but it confuses me - the rims will be going on a Vitz.

WHEEL BOLT PATTERN PCD = 4 x 100mm

CENTRE BORE = 54.1mm

OEM wheel sizes, offsets (ET), and tire 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 tires from 23.0 to 24.3, +/-3%.

__________________________________________________ ________

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

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

Optional tire sizes (diameter in inches):

*Commonly recommended replacement sizes

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

175/65/14 = 23.0*
185/65/14 = 23.5*
195/65/14 = 24.0
195/60/14 = 23.2*
205/60/14 = 23.7*
215/60/14 = 24.2

185/60/15 = 23.7*
195/60/15 = 24.2*
195/55/15 = 23.4*
205/55/15 = 23.9*
195/50/15 = 22.7
205/50/15 = 23.1* (Most lowered applications)
215/50/15 = 23.5
225/50/15 = 23.9

195/50/16 = 23.7*
205/50/16 = 24.1*
215/50/16 = 24.5
195/55/16 = 24.4
205/45/16 = 23.2* (Most lowered applications)
225/45/16 = 23.9

205/45/17 = 24.3*
205/40/17 = 23.5* (Most lowered applications)
215/40/17 = 23.8

215/35/18 = 23.9*
225/35/18 = 24.2
205/40/18 = 24.4

Staggered fitments:

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

Example: FR, ET45//RR, ET38

Example: FR, ET42//RR, ET35

2. Staggered tire 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 tire widths preclude tire 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. Tire rotation is still possible.

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

Based on that, there measurements are concerned with guard clearance, The wider the rim/tyre the higher the offfset needs to be to tuck the wheel in. Rolling guards will significantly change what you can fit.

My dad is running 17x7 Mak rims with a +35 offset on his Vitz RS, paired with 205/40/17 tyres. There isn't a hell of a lot of room between the tyre and the plastic front arch liners when turning but still clears no problem. Would be a different story if he was running 205/45's though.

Before that he was running 16x7 Advanti Fluid's with 205/45/17 tyres, offset was +40.

Springs are standard RS height and no rubbing/scraping with either wheels.

If they are 45p yes they will fit fine, 35p, youll struggle without a decent guard roll.

Even if they are 45p id suggest a slight roll on the rears.

If you are in auckland feel free to drop past and ill give you what ever info you want to know!

You must mean 205/45R16?
