Evening all,

I am looking to purchase some new alloys & tyres that are 205/45/17 5x100 et38. Are these or a big 'no no'??

Any help and advice would be much appreciated.

205/45/17s are too big - you'd need 205/40/17s to keep the gearing right.

A recent thread on this subject is here <--------clicky, clicky,

or another that gives more details here <-------------------- clicky

You need 205/40/17 tyres to keep the right rolling radius to avoid issues with rubbing, speedo accuracy and rolling resistance.

5x100 are right, but i'm not certain on the offset for the Fabia, it maybe et38

There are loads of threads on this subject, so try the search, it's what it's there for:thumbup:

Offset is fine, Best kept between 32 and 42

215/40/17 is an option aswell!

i have 205/45/17 on my vrs and its fine no rubbing and speedo is bang on

Cheers for all the comments and links

Is it lowered at all?

no mate, dont rub at all even when got 4 people in

Mines lowered 25mm so may have issues. Probably go with the safe option 205/40/17

you may think it is but impossible as theres an inch difference in rolling radius.

if wheels are 7 1/2 x 17 and 38 offset ish you wont have any problems with 215's

I have 215/40R17's, speedo is now bang on with what GPS says

Its lowered on Eibachs, and have had no rubbing issues etc

I have now purchased some 205/40/17's will i be needing new wheel bolts?

I doubt it, width should be the same as the tyre width is still 205mm

It depends on the thread on the alloy wheel where the bolt goes if its flat or thicker at the top than the bottom. Damn this is a hard one to explain can anyone help

If your new wheels are original equipment VW, Audi, Seat or skoda wheels you should be fine with the bolts you have. If you look at a wheel bolt the head of it just above the thread is shaped (it'll either be rounded or tapered) - this sits into the wheel bolt recess on the wheel. You need to make sure you're using the right shape of bolt for the recess in the wheel. Usually OE wheels have rounded heads and aftermarket ones tend to use tapered heads. The other point to consider is the amount of thread available to bolt into the hub. If you take a wheel off the car and stick the bolt through you'll see how much thread is poking out the other side. Try the same again with your new wheel - if it's about the same you should be fine.
