also your load rating will be to low

215/40/17 83 load rating which is 487 kg per tyre

235/45/17 94 load rating which is 670 kg per tyre

so a 183 kg down on your load rating per tyre

This topic reminds me of the Capri 2.8i I had many moons ago.

Basically the original diff broke, and I inadvertantly fitted another (secondhand) from a 2.0 Capri - this had a different ratio so that the acceleration was much improved (the original gearing was too long really) but the speedo read way too fast (like +20% I'd guess!!)

I always meant to try to get it adjusted somehow but never got round to it. Once you are used to it it didn't bother me too much. Did give some passengers a scare though when they looked at the speedo....
