Agreed - I wouldn't run MC tyres on a car. Tyre size is a compromise though and you wouldn't be able to carry as much speed into bends with something as narrow as a 145 - maybe not as important on a highway vehicle ? I have 155s on a much smaller car (think Metro sized) and know where the limit is - a lot lower than the 205s on my previous TDi.

What pressures are you running the 205s ? I recall from your early post you had a couple quite low which may have caused some of your lower FE numbers in your OP. I run my 155s at 45-50 (max is 55 and from the stealer they were at 35) and that made an immediately noticeable difference in coasting. If you haven't already then go higher. Eventually you may find the ride is more 'crashy' on rougher surfaces at which point you can gradually ease back to where it is OK for you but firmer than before.

I did this on the TDI for 20K miles and didn't see any adverse wear either.

Good luck.
