forgive me 1st if this had been discussed somewhere else... I looked and read many threads already... Maybe I searched using wrong key words.
my ride - Liberty spec B 2.5 2007 Sedan just recently purchased. It had 215 45 18 of which are worn out.
I happen to have a set of 225 40 18 2 months old and I fitted it of which upon reading further on this forum and doing various checks reveal that
- rim diameter now smaller and will effect the speedo reading by around 2%.
Basically 100km will now be something like 97 or 98 and I will be clocking up the kms slightly faster.
- next best match should be 235 40 18 of which will lower the difference to 0.85%.
BUT further reading shows members on here and tyres/wheel packages from Tempe / TTF for example are using 225/40/18 .
should I purchase a new set of 234 and save the 225 for the wife' aurion? And one more thing ... How come most members on here don't have turbo timer fitted ?
Please let me know so I can use that money for tuning the car .. 1st priority for now.
Many thanks.
Tien
