A couple of questions for you guys.

I have the opportunity to pick up a set of Fox racing 17" off a coworker for cheap. They are on a Ford Sierra and I just want to make sure they will fit. I imagine they are 4X108 just like the mondeo but am unsure. Not sure of the ofset but the tyres are 205/40/R17...rubberbands! Any ideas if they will be good?
Hope to get pics later on today.
Cheers,

From what I remember of my Sierra (1990), they should fit. But I'm sure someone else will be along in a moment to confirm this..or not.

I am thinking that they will fit. I just need a second opinion to confirm it.

I know for deffinate that they bolt on as I fitted some Focus steel wheels on to it when I sold it. And I know Focus wheels also fit onto the Mondeo as I has ST170 alloys fitted for a while. It's the the offset that I'm unsure of.

another issue with the wheels...the right side tyres are 205/45/R17 and the left side tyres are 205/40/R17. Isn't that against MOT standards????

I beleive so. It will also make traction control think that one side is wheel spinning and then activate.

It does matter on the mot but you can still get away if you put both of the 205/45/R17 on the back and The 205/40/R17 on the front or vice versa. If you do it that way It will pass for an MOT just happened on my brothers Fiesta.

Hope It helps :L

Was sort of thinking that. Only problem is they are a directional tyres. Just can't swap right bact to left from or vice versa. So will need at least 2 new tyres on it from the start. Now just to figure out which ones to go with the 40s or the 45s.

I had 45's on the ST170 alloys I had. Some others have tried both and most seem to prefer the 45's.

I think that the 45s are the ones I want. They appear to fit the rim just a bit better.

45`s look thicker matey. i have 45`s on mine ( 205/45/w17`s and they fill the rim better. ) the 40`s look a bit small and the ride is slightly harsher. BTW think the sierra was a ET of 35-42 on the PDC of 4x108 as i had 15" mondeo si rims on my sapphire and they fitted no probs and no rubbing with 195/50/15`s

Still at a loss on these. i know that i can get these cheap enough, but know i am going to have to pop 2 new tyres on right away to get them all the same size. Also, two of the wheels have alot of curbing on them and i am worried about them. That said, I do love the look of the wheels though!
