Regarding diameter
235/55/17=691mm
255/45/18=686mm
In my non expert opinion 5mm difference won’t destroy front differential if you fit 17” spare
I fitted 255/55/18=737, I don’t do much city driving but for country roads the ride is heaps softer with higher profile
Hey Kombi,
What brand did you go with for the 255/55/18?
Just back from a farm stay - got stranded after the standard fit Bridgestones gave up the fight with the gravel roads.
No spare. Repair kit didn’t work. Hopeless.
Thinking a bit more sidewall will improve things.
Have you got a spare? What fits under there?
Cheers!
Tim
