Speedometer

Could anyone tell me the serial no. and TPM of a speedo fitted to an 8cwt van with wide wheels and 165 sect tyres please?
Thanks

Depends on the final drive ratio - and the aspect ratio of the tyres. Since most Minor speedos were ~ 8% fast as standard - you may find the standard speedo is actually more correct now with the wider tyres - if they are 70 aspect.

I was after the standard fitted speedo serial and TPM for an 8cwt van which would have 165x80 tyres and 4.55 diff. Presumably as the overall gearing is slightly higher than a 6cwt on 145 tyres it would have a different speedo.
I am trying to add some more info to the speedo table on the Series MM website.
I am also interested in any info on KPH speedos fitted to export Minors.

I didn't think any Minors had 165 X80 X 14 tyres as standard? Did they ? I thought all production was on cross-ply tyres! Maybe they had 5.90 X14 tyres ? That's what I used on my Rally Minor.

As 8cwt vans came in towards the end of Minor production it is quite likely that they had 165 tyres to fit the wider rims

Any evidence to support this ? Personally think it's HIGHLY unlikely!!
