Speedo is 10Km out?

1

It appears that my speedo is 10kph out on the high side.  at 100kph I am actually doing just 90kph. Is this common?


If I ever find a set of 15" wheels and 215x75x15 should get the speedo set correctly.

Original 14" rims and worn tyres might cause that.

BFG 215 75 15 AT tyres would be closer to accurate.

That is normal. All speedos are 5 to 10% over.
