I have a 2010 SE estate on standard 15in alloys. Currently I have 205x60x15 tyres, which I have found are not a common size and hence more expensive.

 

Can I replace these with the alternate sized 195x65x15 on the current SE rims? The 195 seems to be an option for the car and more garages stock it (cheaper too). I am guessing these are the standard sized tyre for the greenline or S trim?

 

Obviously if I were to change it would a full axle.

I believe the standard size should be 195/65 R15 on 15" Pyxis alloys, unless you have the 4x4 where it's 205/60 R15 on the same rims.

 

I would image either are fine although I'd suggest that all four are the same size

It will make a minor difference to the speedo to as you will be changing the circumference of the wheel/tyre combination by about 2.5cm.  That will give an error at 80mph of 1.03mph.

 

I wouldn't worry about it but at least you will be aware.
