Wheel by wheel: offset and tyres

Each original wheel from Mazda CX-5 is compared with the one from Mazda RX-8 of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

    Compared with the original ≈6.5Jx17 ET50 on Mazda RX-8: shock absorber side +6.3 mm, wheel arch side +6.3 mm, tyre diameter +10.2 % : fit it with the original tyre size of Mazda RX-8 (205/55R17), not that of Mazda CX-5. Comparison for guidance only (estimated width). Check in detail

  • 7Jx17 ET45 · 225/65R17 — Check on the car

    Compared with the original ≈6.5Jx17 ET50 on Mazda RX-8: shock absorber side +1.3 mm, wheel arch side +11.4 mm, tyre diameter +10.2 % : fit it with the original tyre size of Mazda RX-8 (205/55R17), not that of Mazda CX-5. Comparison for guidance only (estimated width). Check in detail

Before fitting the wheels

An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Mazda RX-8 (Ecrous - 12x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
