As you have probably read my other post's, I need to chnage some tyres on my dad's FL SRI CDTI, currently running on Goodyear NCT 5 215/50/17.
From another posting, someone has mentioned I shoudl go to 225/45/17 instead of 215/50/17.
Can anyone comment on their thoughts on this please, and also those that have changed to thse, can you please tell me the difference and/or benefits that you have seen? Do I need to have anything done, i.e. speedo calibration, etc?
