Toyota IQ wheel fitment — AJ1, /-MS1
Toyota IQ wheel fitment
Toyota IQ wheel fitment comes down to two things: the factory hub spec, and how far the aftermarket width and offset can move from it. Both are here for the Toyota IQ AJ1, /-MS1 (2012–2015).
| Bolt pattern (PCD) | 4x100 |
| Centre bore | 54.1 mm |
| Bolt / thread | M12x1.5 (nuts) |
| Wheel-bolt torque | 105 Nm |
| Seat type | flat |
| Factory setup | square |
| Tyre pressure | 36Psi |
| Brakes | e6*2001/116*0119*..;e11*2007/46*0238* |
| TPMS | direct |
Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 5J–7.5J | ET30–ET45 |
Go wider and the offset has to rise with it, about 8 to 10 ET per extra 1J, or the wheel pokes past the arch. The fit-check settles the exact offset and any spacer.
