Hi Guys,
I created a new topic as it's very specific to the FE and winter tyres.
If this is not OK can Mr Moderator please move it?
I've been trying to locate 235/55/R18 winter tyres, national suppliers and usual internet sources, with no success.
However, a search of compatible wheel/tyre combinations on the internet shows 225/65s on a 17 inch wheel gives an overall diameter within 1% of the 18 inch wheel combination. Great! So I phone my local Kia dealer to ask how much for 17 inch alloys;(I think they are used on the Sportage KX2, which has the same engine, 2.0L CRDI, with the same torque, brakes etc as the FE).
He then tells me there is an email from Head Office saying that on no account should wheel sizes be changed, either 'blinging' up, or sizing down, because of the different torque/speed characteristics between models, different speedo take offs (and its effect on the engine management inputs etc etc.) I can see the issues if someone tries to put 18in wheels on a 1.7GDI powered model, or tries to put 15inch wheels on a FE.
But a general ban doesn't seem right? A 1% difference is probably less than 6 months wear on a normal tyre set!
Please. can anyone with 'inside knowledge' shed any light on this.
Thanks Sparky
