Styling Wheels & Tyres

Re: Wheels & Tyres

I've just asked for them to repair the kerb damage on 3 of the wheels, they are going to acid dip them to bring the paint back up and spray using the original paint where they have to to fix scratches etc.. Want to keep them as original looking as possible.

Re: Wheels & Tyres

Well, I fitted the front two wheels a few days ago and they are staying on, and the bolts are not coming loose or anything (catching around 7.5 turns), however I've just tried to fit the rear wheels and the bolts don't even catch 4 turns! So I'm assuming this means I need longer bolts, any thoughts or recommendations where to get them from and what length I may need?

Re: Wheels & Tyres

1 turn = 1.25mm, so work it out from that. Personally, I'd go for a stud conversion: easier, safer, and better when stuck at side of motorway with poor Polish truck driver (paid £2.50/hour, hasn't slept for 15 hours) bearing down at you at 65mph.........

Re: Wheels & Tyres

Sorry to be ignorant, but what's a stud conversion?

 

[fingers99]

Re: Wheels & Tyres

You swap the bolt for a stud and nut. Here for example.

Re: Wheels & Tyres

Talking of stud conversions, does anyone know where you can get these where the thread has been formed to a close tolerance?

I'm having huge problems with my lightweight wheel nuts, made to very tight tolerances, they go fine onto Subaru OE studs but keep jamming on the convertors I've had from Rally Design and a local motorsport vendor.

Re: Wheels & Tyres

Most UK stud kits come from one source, whoever sells them. There is a fastener specialist advertising in PCC who -- it seems -- make stuff for F1. Might be worth a go. The issue may be with the plating (which seems a bit clumsy) rather than with the thread itself.

Re: Wheels & Tyres

All this stuff is easy to work out if you take a disc/drum off

1 turn = 1.25mm, so work it out from that.

I'm not really finding it easy to work out at all.

So if 1 turn = 1.25mm, how many mm do I need catching in the hub?

There's an ad in the classifieds saying that 24mm bolts is recommended for standard alloys on most FIATs, but I measured my bolts and the thread length is 21mm, so I can't see 24mm being enough? Unless I'm measuring it wrong. I also measured the length of the bolt excluding the head and the tapered bit and that is 27mm. My bolts do over 10 turns using the original steel wheels (this is the rear) so do I have to measure the width of the bolt hole in the alloy to calculate the new bolt length? Because that seems difficult if not impossible to do.

Re: Wheels & Tyres

I don't know how accurate, but I read somewhere that a minimum of 8 turns (10mm) is recommended.

A couple of 42mm wheel bolts arrived this morning... needed because of the mysterious inserts in my alloys. On the packet it 'customers should ensure that a minimum of 8 full turns are made'

Sounds like you got them from the same e-bay shop I got my wobblies from

Re: Wheels & Tyres

So basically, I've got to end up with a set of bolts that do up at least 8 turns, so as I know my current bolts are 21mm and I need a further 7 turns (seeing as the back wheels only do up to 3 turns currently) so I need

7 X 1.25mm = 8.75mm extra length

(round up to 9mm) 9 + 21 = 30mm bolts

So I need 32mm bolts as the closest match if my calculations are correct? Does this sound right?

Also, these bolts won't be too long for the front wheels will they?! Seeing as they already do up 7 turns on 21mm bolts...

Re: Wheels & Tyres

Take one wheel bolt, measure the length of the bolt to the beginning of the taper, make a note of this number. Then with the bolt pushed fully home in the wheel measure the amount of thread behind the wheel. Take away the exposed thread from the total length of the bolt thread & note this number down. Next remove disc and measure it's thickness around the bolt holes & then measure the thickness of the hub flange, note down both those numbers.

You now have all the numbers you need, add them all together plus the depth of any spacer you may be using & finally you add 2mm. That length is the minimum bolt length you want. Though it sounds complicated it's damn simple to do.

Re: Wheels & Tyres

One thing to watch is that the bolts may be too long for the spare -- especially on the front. Check! If it's the case, you'd better carry some shorter bolts around with you. This is why I like stud conversions..............

Some spares have spacers welded onto the front of the bolt holes to avoid this problem, others come with a set of inserts to use when fitting the spare.

Hi David

My sei comes with a cute plastic box with spaces for the locking nut driver and the four bolts for the spare, or I assume that what they are, the handbook is less than helpful.

They're just 4 standard bolts, not specific to the spare wheel

Re: Wheels & Tyres

The spare is pressed steel the others are Al alloy, I think you have to fit the correct bolts, when you get a puncture or get one fixed?

That's a point -- I came across the issue when using the spare on the Orange Sei (which has a Punto spare). Since then I've done the sane thing and put studs on it.
