I have a set of 17" OEM wheels that I've not used yet - I was planning to keep the Geolandars on the standard rims for use in the winter months and have the 17s on in the summer.
Now that the weather is beginning to warn up, it's soon time to put some summer tyres on and I'm debating what size to fit and whether to use the 17s or stick with the stock 16s.
215/55/R17s and 225/50/R17s are closer to the OEM 215/60/R16 circumference but 225/45/R17s are considerably cheaper though a bit smaller... has anyone run 225/45/R17s?
Obviously the speedo will be further out with the 45s (can this be adjusted via the ECU - MY03?) but is there likely to be any difference in fuel economy due to the smaller size wheel (more RPM per MHP)?
The alternative is to stick with the 16" rims and go with 225/55/R16s
Thoughts, opinions, etc???
