Tire size/pressure advice 17" gt
Hi, just curious really.
My 06 gt 2.0 jts manual says tire size is 215/45/17 but when I put my reg plate in to various websites it tells me to buy 225/45/17. Is my manual out of date and should I have 225's instead? I put on 4 215/45/r17 87w Dunlop sport 3000a about 4 months ago as the manual said these were ok. A few questions;
Should they be 225's,
What tire pressure should I run my current 215's,
How would the ride change from moving to 215 to 225
And finally, would it make a difference to reported mpg, mph on the Speedo and miles travelled on the trip?
Thanks for your help.
