Hello everybody

If I am considering buying 17inch rims for my Fiesta, what dimensions should the rims have:

Thanks in advance for your guidance :)

The streetpack 17" alloys are 205/40/17. Though others that have a similar total diameter/circumference (ie wider and lower profile or narrower and higher profile) also fit. They would affect the speedo though, so best to stick to what size Ford use!

So if I choose the 205/40/17 it won't affect it right?

What about these dimensions?

205/40/17 are specs for tires....or tyres. The 205 would be width of the tire in MMs, the 40 is sidewall height (40% of 205mm in this case) and the 17 is for the size rim it goes on....in inches.

For rims, you need to be concerned with lug pattern, size (diameter and width) and offset.

Offset is where the rim's hub lines up with its center line. I think most 17"x7" rims with offset @42 will work, but don't take my word for it. I have one set of 17" rims with a 45mm offset and it does not rub. I have another set of 17" rims with a 40mm offset and it does not rub. I am no expert on the matter and only kinda read up on it when purchasing the rims, but I think the lower the offset, the more pushed out the rim is and the higher the offset, the more sucked in it is. Like my 17"(diameter)x7"(width) et45 set...where the wheels attach to the hub, has the tire pulled more in towards the suspension, while my set that were et40 was pushing the tires out towards the wheel wells edges. This is important because you don't want this number to be off to the point that you rub either on your suspension or your wheel wells.

Rim size is just diameter and width. Easy enough. I don't think you want to go over 7" for width. I have seen people do 8" on the Fiesta, but that is stretching the tire in order to keep it from rubbing. Just keep it simple and don't get a rim wider then 7". Possibly 7.5" will be fine too, depending on the offset. Seen 18" diameter rims fitted and they are fine, but they just look kinda too big for the car to me.

Lug pattern is 4x108 for the Fiesta. 4 is referring to the number of lugnuts/holes and 108 is referring to the spacing/pattern. It has to be 4x108 otherwise it will not line up with the lug patern on the car's hubs.

Thanks Casca for the detailed information. I will try to check it out with the place that sells rims. Hope they can help me :)

Have a great weekend!

Thanks a lot! This info is really useful :)

Tato,

Sorry gave you the wrong ET, it should have beeen 47.5mm ET.

See page 44 of the catalogue.

Don't forget that Ford fit steering rack limiters to the Fiesta when fitting 17 inch wheels.
