If my calculations are right you should be OK.

Relative rolling radii are 239.77cm & 239.73cm

England 

the space saver spare is always a 19", irrespective of what size tyre is on the car. I know yours is a ful size spare, but that size is OK with your 18's.

Thumbs Up I still carry an 18" as the spare under the car even though I'm running on 19" as the change in profile evens out to rolling radius issue
