Wheel sizes with tyre height for formentor.

[Sartuzi]

Hey there,

Does anyone know if 19inch wheels and 45profile tyres would fit? I Know the VZ5 has 20" wheels but lower profile tyre, so was wondering if all formentor variant wheel wells were the same size.

Yup. Standard wheel and tyre size on many formentors

245/40R19 94 is the standard for most formentors. I think the V1 has 18 inch wheels as standard but 19's will fit no problem.

Yes, so out of factory they come 245/40/R19, I wonder if 245/45/R19 would fit, since looking deeper into the arches near the bottom it seems like it would be a tight fit.

@Sartuzi; be aware that increasing the tyre sidewall height will result in a speedometer reading error. According to the tyre size change calculator at the link below, with 245/45 R19 tyres your speedo will under-read by around 4% compared to the factory fit 245/40 R19 tyres, so when your speedo is indicating 100 kph, your actual speed will be 104 kph. It would be worth checking in your country (Lithuania?) whether or not there are any legal implications of having a speedometer that over-reads or under-reads the true speed being travelled.

Speedo error calculator calculates speedometer error as a result of the change in tyre size. It shows the actual speed your car is going after the tyre size change.

This is great, thanks! @SRGTD

Not all tyres are equal in size.

Michelin Pilot Super Sports were a touch wider than advertised.

The side profile value is the percentage of the tread width?.
