should that be 16.9 x26. Our Marshall M tyre can be stretched a bit to this size. Chestnut miniatures use them as combine front tyres on the Allis Gleaner & Clayson.

cheers nigel, is there any current britains wheels that would be similar by any chance?

[Tractorman810]

anyone able to tell me roughly what size that would be in 1/32, or what the origonal size is so i can convert, is it dia x width ? or the other way round

[Dwross]

The 26 is the rim diameter in inches that the tyre is on.  The 16.9 is what is called the section width, the tyre at is widest part., again in inches . You would have a 100% ratio so would be roughly the same height as width with a full tread.  More technically this is measured at a standard pressure and load.  Divide by 32 to get the scaled down sizes.

cheers david thats just what i am after , time for some working out now

[Lord Ferguson]

So... (please tell me if I am wrong)

The wheel diameter is 26" plus 16.9" PLUS 16.9" - Is that right then

[Dwross]

Yes

[Lord Ferguson]

Thanks Dwross... so then...

26+16.9+16.9 is 59.8" (the tyres... sorry Tire if you are in uncle shermans garden.... height is)... 59.8"

Which is.... 1518.9mm... lets call it 1519 shall we...

1519 / 32 is... 47.46mm... so that's the height...

Width is simple... 16.9" wide is 429.26mm lets call it 429mm.... 429mm / 32 is 13.4mm... so that's the width..

No then Mr Pullen... do you have a tyre that's 47.46mm tall and 13.4mm wide then 

[tanvics71]

STANDARD TRACTOR TYRES SIDEWALL IS 95% OF TREAD SECTION WIDTH NOT 100%

EVEN THOUGH ITS NOT MARKED ON OLD TYRES 16.9X26 IS ACTUALLY 16.9/95X26 BUT THEY DIDNT BOTHER PUTTING THE 95 ON SIZE MARKING IF YOU WANT ILL LOOK IN TECH DATA BOOK TOM AND GET CORRECT HEIGHT ECT IN MM

PETE

Thanks Dwross... so then...

[sparrow legs]

be like me, find the wheel and make it fit as people put different variants on over the years

[Tractorman810]

i might just do that sparrow, think i may have found a possible set, but only a cheapo set, really want a britains or siku set it poss once i know the proper size

The only problem with scaling a wheel/tyre size exactly is that the model you put the wheels on may not have been scaled correctly in the first place. Sometimes you just have to use whatever looks 'right'.
