2007 Defender 110 Puma 2.4 SW Java Black
Speedo Calibration
Hi,

I'm about to change from 7.5 R16 Latitudes on 5.5 steels to 235/85 R16 Wrangler MTR's on Boost alloys and was wondering what, if any, difference these will make to my speedo calibration on my 2007 Puma 110 given the slight difference in rolling circumference?

Also, as these are both standard fitments on the Puma 110, did LR calibrate the speedo differently depending on which tyre/wheel combo they were supplying on the vehicle?

Mark

Both about 31" diameter so should not be any problem
