Hi everyone, I'm a newbie just joined so bear with me please if I sound like a twit/monga etc or I've posted in the wrong section(!)
Ok, my question is this: I've just bought a brand new Zetec 1.25 (the facelifted version with the humungus front grill, does that make it a Mk8?) and while it is an excellent car so far (light years from my old 1999 Zetec), I feel the wheels could do with an improvement - they look a little piddly if you get my drift?. The car came standard fitted with 15" 5 spoke alloys (Ford code 1 817 616) with 195 55 tyres. I've looked on the Ford UK website and have seen a set I really like; a 17" 8 spoke job (Ford code 1 817 293). Using the tyre size change calculator on etyres website, it turns out that fitting 205 40 size tyres to the 17" alloys will keep the overall diameter of the wheel at exactly 596mm so no probs as regards to gearing or speedo accuracy. I have also found that the offset on both types of alloys is exactly the same: ET47.5mm so in theory, no probs there either (I think?). My question is this - does anyone know if I can simply buy the new set of 17" alloys and fit them in place of the standard 15" ones (seeing as the 17" alloy is fitted as standard to higher spec Fiestas) or will I/could I run into probs as regards to fouling the wheelarches or suspension strut etc? I know the overall width of the wheel with the new alloys and tyres will increase by 10mm but would I still be ok? Any thoughts anyone?
