Alloy wheels (NOT Motorhome) - Have I balls'd up? Advice welcome...... Help!

[Jev88]

The Mrs has a Fiat 500 2012. Little 14" steel wheels. 4 stud 4x98.
Found some cheaply priced Fiat Punto 2011 alloy wheels 15" and had them sprayed / baked to Red colour to give her a bit of bling. 4 stud 4x98.

Fronts seem to fit pretty well, no gap from wheel hub to inside surface of wheel (as far as I can tell).
Rears - Different Story! - it has drum brakes rear and I can't get the new alloys over the central part (hub?) that sticks - so, so Close, but not quite!

What have I forgotten to account for? Maybe ET - offset? NO arch rubbing etc but the wheels simply are not fitting snug. The central hub is about an 8mm protrusion so I thought perhaps some 10mm universal 4 stud wheel spacers would remove this problem?

I don't mind being called a twit - just remember I was doing this out of kindness to my better half (had to say that as she is looking over my shoulder.......)

Your a twit.
There you are I gave you a funny and called a twit.

Fancy spending all that money on them without checking first. What a plonker is more appropriate.

Oh bugger - Might have solved it myself. Fiat Punto in 2007/8 had a cross over and some cars had Centre Bore 58.1mm (same as Fiat 500) and some had Centre Bore 56.6mm........ Might explain why I am so close to fitting! Have I hit a brick wall?

Does the above link make sense in terms of your problem?

Thankfully they were cheap and should get my money back but she loved the Fiat Red colour I had them painted!

It’ll be something to do with the offset.

You won't be the first trust me!

Can you get them machined?

e.g. http://www.tttoolsltd.co.uk/services/

 

[RandallC]

personally I’d just locate a decent machine shop near you and get them to bore out the centre hole to the required size. 1mm a side change in centre bore is in reality very little. Make sure you do all 4 just in case You need to rotate or next tyre change they do a side at a time

You need something like this:

I understand how spacers work and also how PCD adapter bolts (wobbel bolts) work but I will have to email that supplier to see if the smaller wheel centre bore (56.6 against 58.1) means I simply can't use the wheels.

I would have thought a machine shop can sort it.

Agreed, just need to find one in Peterborough now.

so close to fitting! Have I hit a brick wall?

No but it will cost yet more money.
A machine shop will open up the wheel centre to suit the drum flange.

Nah! Looks way too small .

As an alternative to machining four wheels, you could get the two hubs machined down. Just about anyone with a lathe could accommodate those.

If you are fitting wheels not originally part of the vehicle, that are from a different vehicle (even if there is a close apparent match), this is a customisation. Check your insurers will accept it. People are suggesting drilling bits out, fitting spacers or whatever. Is that still satisfactory perhaps it could be changing stresses on the wheel hub, studs or other mountings.

Now I have fathomed that the wheels are an older internal hub of 56.6 I am going to get all 4 done as although it feels straight at the front I can't be sure. Either that or I sell the lot and buy new.......

I hear you, but I am only going one step away from factory, a few mm.

1,5mm Run a flap wheel through it a few times.

Reducing the wall thickness could seriously weaken the hub and machining the wheels could also weaken them.

 

[Supaimpy]

Need to confirm whether the original wheels are hub centric, (that is aligned by the centre ) rather than aligned on the bolts. If they are then spacers will not be suitable

 

[Carpmart]

You can get some 5-10mm spacers made (or buy if available) with the 56.6 bore one side and 58.1 flange the other, way easier than machining the wheels. 5mm extra offset should be negligible in terms of clearance, but do check...
