Morning all, a quick one on tyres

[b2tf]

Just a query, Focus MP3 rims (17") will fit a Fez ok yes? I have heard stories of Ford denying them as an option and telling owners to go with the 16" versions instead.

On mine I am running 215/40 profile tyres, I am assuming these would be ok on a Fez too?

TIA.

[Timmeh]

I have heard of it done, buthaven't done it myself. I have a spare set of MP3 rims in my garage that I was going to test fit to Lotsy's Fiesta but we ran out of time modding her car.

I'll try it sometime if no-one can give you a definitive answer, if Lotsy's over anytime soon.

I think Ford's problem with the setup was that the tyres need to be a 35 or 40 profile on 17 inch rubber - if you're running 40 profile on your Focus, that's pretty thin and I'd suggest your speedo is out, because 45 is the factory approved profile for 17 inch rims on a Focus.

Dunno.... my dealer just wouldnt let me take delivery of the car with the 17s...

Tim

speedo calibration may be your answer, also tire ratings adn their suitabilty may also be a consideration.

[b2tf]

Tim I checked this morning and I am running 45 profile, sorry, was past midnight and i couldnt remember what i had - 40 or 45. So speedo should be fine yeah?

[Perana]

Im sure I have seen them on a Fiesta over here somewhere.. Looked like they fitted alright..

Yah ive seen them on a Fez too but im not sure if they were 16's or 17's - the wheels are available in 16" too.

[Perana]

Im fairly sure these were 17's..

[outback_ute]

How do the 15" tyre sizes compare between the two cars? Does the Fiesta run a smaller diameter tyre?

[GROOV3]

i have the factory 16 " and the tyres that came with them are 40 profile


and the car i tested had the focus 17" but they guy is like you cant get them

Possibly, not sure. Focus runs 15x6.5" steelies standard (i think?), mines wearing 17x7's.

[Scareybear]

The Fiesta 15" tyres are a 195/50R15 where the foci's are 195/60R15, a bit taller.

[Teki04]

There is a fiesta in the nxt suburb.... has the zetec 16s on it from the focus series 1

[zetec]

That would look good. Focus Zetec 16's run a 50 profile.

[RichieMK6]

i have a 40 series on my 17 < house tyre but my speedo dosnt seem to be out

[0xyg3n]

going on the std fiesta tyre being 195/50/R15

Speeds of other tyre sizes should be:

Optional Fiesta 16's
195/45/R16 = 101km/h or 1.0% over
Others
215/40/R16 = 100.4km/h or 0.4% over
205/40/R17 = 103.4km/h or 3.4% over
215/40/R17 = 104.8km/h or 4.8% over
205/35/R17 = 099.0km/h or 0.1% under
215/35/R17 = 101.1km/h or 1.1% over
205/30/R18 = 100.7km/h or 0.7% over
215/35/R18 = 101.8km/h or 1.8% over

[Teki04]

what is the legal % difference allowed?

[0xyg3n]

i think in vic its 2% but iam not 100% sure on that. Other states might be different.

If it goes up than thats fine for me because my Fiesta speedo is out BIG TIME. When i go through the speed measuring device on the Geelong freeway its only doing 94 when it shows 100 km/h.

great data, where did you find this? would be interested to look at other types

No... i was in a hurry to get to the police station, only to see them before hand! :gren:

Not 6 kays out mate..... 1 or 2 kays is the general average with most cars at 100km/h indicated.

[fordel]

now if i cbf i would pull the 17's off the focus and chuck them onto the fiesta to give you all a answer if they would fit or not

but that would be work and i am on holidays

Chris

[0xyg3n]

The focus 7 spoke wheels like the ones below do fit the fiesta.

The focus ST170 wheels also fit. :P Just dont put 215/40/R17 rubbers on em.

[Timmeh]

The rims in the photo you posted appear to be the optional 16 inch Fiesta rims, as seen here on Teki04's car, from making the photo light to look at the tyre details on the tyre wall, and looking at the size of the rim compared to the guard:



However, I do reckon it's possible. I have a spare set of the 17 inch MP3 rims in question sitting in my garage, I just need a Fiesta to try them on!

Tim

[GROOV3]

look i can tell you they fit 100 percent they fit as when i baught my car over a year ago the test car was the fez with striped and the ford 17" rims on it, yet you arent aloud to order them

they fit fine as long as the tyres arent to wide

Yeah I have no doubt they fit but if Ford wont let you order them with the car then there has to be a reason for that and Im wondering what it is.

[Timmeh]

I'd say that's a pretty easy one!

No Fiesta comes out standard (or optional) with 17 inch wheels so I bet they are not listed on the Fiesta tyre placard (found on every vehicle), and therefore dealers won't sell the Fiesta with a factory Ford rim that is outside the vehicle tyre placard specifications.
