Wheels

[Bola]

        Hi, a wheel question plz

I found these 307 wheels for sale locally. So my question is, will these just bolt on or do I need longer bolts/studs. And are there any disadvantages to changing my rusty old steel wheels with these?
Current wheels are 195/65/15, these are 205/55/16 so similar RC

The bigger wheels will affect your speedo, and may be an insurance issue if they are a non standard size.

Take a look on this website for bolts PCD & Offset etc:

Alloys often have different stud/bolt design, with a thick flat washer mating with a flat face on the alloy, whereas steels are usually countersunk. So if you do change to alloys make sure the bolts come with them!

I have checked the Rolling circumference and it's ok. Some berlingos were fitted with 16" alloys but not this style. they are 108mm pcd so that is ok too I think.

I can always nip to the scrapyard for bolts, but that's a good point. The Alloys from my old rover were round-bottomed bolts. I don't expect bolts to be an issue but worth thinking about

You need to know the ET of the rims as you may need spacers with them to stop the tyres from catching the inner wheel arches on full lock as well as needing the proper studs. 307 rims seem to be ET30 or 31 Berlingo around ET27. 4mm difference you might get away with it, Opponeo has a good explanation.

Good link.
Hopefully, someone else has tried 307 wheels on a Berlingo and will know

I fitted C4 VTR alloys in 17" and never had a moment's issue with them. You do need the bolts for alloys as the steel wheel bolts are the wrong taper behind the head. Round vs cone shaped on the steels. Get the alloy bolts, you definitely need them..the 307 wheels should fit perfectly.

You can always declare the alloys to your insurer, it won't make much difference and better that they know. Click the thumbnail to see mine:

Out of interest, as I'm happy with my old steel wheels, do the C4 saloon tyres you have there meet the same load carrying spec as the 'van' tyres that would normally be fitted ?

Yep, they came fitted with Nankang XL rated tyres as the C4 Picasso is a people carrier so is above the standard weight for a car when fully loaded. The B9 Enterprise is rated to carry 625kg load in the back so is below the 2 ton limit anyway for a panel van. Both vehicles share the exact same floorpan and mechanicals.

You can buy XL (eXtra Load) tyres in most brands and sizes now. 100H or 100V are for example, rated at 800kg per tyre (3.2 tonnes total) so even 91H meets the "van" requirements at 615kg per tyre or 2.4 tonnes max load in total.

Black circles have a chart online for anyone interested.

Mine passed two Mots in two years with the alloys on and only in the last year did I replace them with Goodyear Vector IV all weather tyres which again passed the commercial MOT.
