    hi, its not only the diameter and tyre size you need to think of with wheels. you need the number of studs and the hole centres also, not to mention that some wheels have different angles on the wheel nut seat. so check and double check if they are not listed as direct replacements for your wheel hubs.:thumb:

    You will need to know what your base vehicle is Fiat or Merc or ford cos only they will fit. the holes are set different some are 5 stud an some are 6 stud, you need to be aware of this.:thumb::thumb::thumb::thumb:

    unless someone knows what your stud /bolt pcd is ,i would say they cant tell you .
    there are loads of stud spacings .
    are you on 5stud or 6 stud to start with ?

    also it depends on the wheel offset.

    looking from the front or rear of the wheel its the distance the studholes are from the centreline of the wheel.
    too much and the wheel with rub on the suspension....not enough and the wheel could rub on the wheel arch.

    then of course, theres the shape of the wheel....will the brake disc and caliper fit inside it or will the caliper foul the wheel.

    far to many variables to make a guess.

    why not wire brush the wheels with a twisted wire brush . then give a coat of hammerite them while its still wet spray with a an aerosol with steel wheels silver ,makes even old crappy wheels look nice again . then have new tyres and valves all posh again .
    spray can of silver hammerite is best .

    They'll probably fit the tyres, but not the vehicles. You need a match for:
    1. Diameter of wheel
    2. Depth of rim (tyre manufacturers will publish an allowed range)
    3. Number of holes
    4. Diameter of holes
    5. Nut bolt seating angle (can also replace bolts/nuts to match)
    6. Maximum load capacity
    7. Maximum allowed tyre pressure
    8. Hub/bolt centring (hub centring common on dual rear wheel - DRW)
    9. Hub hole size (must be exact for hub centring, or at least required size for bolt centring).
    10. Offset (how deeply set into the wheel the bolt flange.

    Cars often have the flange right on the outer edge when no wheel covers are intended. SRW commercials often have flanges in the middle which makes them stronger and cheaper. DRW commercials have flanges well outside the hub edge, so two wheels can be bolted back to back without the tyres rubbing.

    Thanks guys I'm almost sorry I asked. It seems from all the great advice received the best solution would be either a refurb or as suggested I wire brush them and spray with hammerite silver paint. Even if not a great job this will look better than they do at present.

    Once again guys thanks for all you help. I will soon have the Beast looking as good as new.

    if you use hammerite then use the smooth stuff....nowt looks worse than dimpled wheels.

    and after rubbing down give them a coat of hammerite primer/undercoat to provide a proper key.
    hammerite is different to ordinary car paint...its a form of enamel...so spraying wheel silver while the hammerite is still wet will possibly cause a reaction.
    never tried it but logic says dont mix different paint.

    once hammerite is completely cured, approx 24hrs, it can be overpainted with any paint.

    hi .yes silver hammerite .
    2nd look in a good accessory shop they will sell something like hycote spraypaint ,,wheel paint silver .
    this makes them look a sort of factory finish . not as glarey as aluminum spray paint .
    with a bit of care you can make them look like new . put some nut covers on or dayglo check it arrows . ask in the accessory shop . you have to know your wheelnut size


    pappa thats why i say spray the silver on while the hammerite is still wet .it smooths it out a treat .
    give it a try learn something new. it works honest.
