Hi folks I hope you can help, my 1981 puck came with inner tubes on the 10 inch wheels, I have now got
a new set of tubeless tyres the wheels are a little rusty around the valve holes and the tyre fitter says to fit them
as they may not seal with out tubes others have said tubes on tubeless tires can cause blow outs as the inner
tyre surface is rough and can wear the tube through causing a blow out , the tyre fitter says modern tubes are designed to
be run on modern tyres and many new trailer's have inner tubes fitted and being only a 450 kg puck I would
be fine so my question is what do you classic puck owners have tubes or not ? And what tyre pressures do you
run them at
Cheers scooby puck

I would clean up and repaint the steel wheels rather than use tubes.
The modern tubless tyres are very rough inside and could chafe through
the inner tube resulting in instant air loss.

Thanks for the reply crow I think I will end up getting the rims shot blasted and re painted ,
I just want to be safe and do the right thing, the fitters say its the valve hole that might not
seal without tubes and one suggested welding it up and drilling a new hole on a non rusty
part these steel rims aren't available any more so I will have to get them restored some how
any way It still would be good to get other vintage eriba owners views if there are any on here

Thanks guys do I measure between two bolt hole centers for the pdc if so it's 70mm with a 60mm center hole for the axle shaft
the wheels have MEFRO stamped on them I think thats the manufacturer and 3.50 x 10 and the year 1980 the only other number
is 602800 may be a part number there dosnt seen to be any offset they are no deeper which ever side you look at so I don't know
what offset that would be called ? 0 may be ?

Can any one help me locate a new set ? Or what spec to ask for when getting new repro ones I just need pcd and correct offset
cheers scooby puck

Thanks] i'lI re measure the opposite bolt holes then



cheers scooby puck

Right they are 100 mm between the bolt hole centers I can find some new mefro ones on ebay but there 4 inch
which is just over 100mm would they fit ? Or do I have to stick to 100mm its only 2 mm difference
cheers scooby puck

Hi Randa the tyres are 145- 80 -R 10
Cheers scooby puck

Thanks Randa yes they are the same as the french guy 100mm pdc and zero offset , ive messaged the ebay seller
to see if he knows if the 4 inch pdc would be ok there isn't much difference the french ones look good but the ebay
ones are in the uk so I will see what they say first
meanwhile if any one else knows please let me know
cheers scooby puck

Hi your right not close enough the ebay guy says he may be able to get the right ones in with the melfro number
so we will have to see what happens
