Had to replace my NSR tyre due to damage from a nail.

Got the same make/size Pirelli PZERO etc. The OSR tyre has a lot of tread left, feels almost new.

Should I have replaced both? Rang my Subaru dealer and they said should be ok.

Wanted to check with you guys.

 

As long as the difference isn't too much it will be ok.
How many mm difference is there?

 

I'd say about 2mm MAX. I think???

 

Stick the new one on the near side front - it will wear slightly quicker (hence even the wear) due to taking the load on roundabouts.
Thats the reason they swap fronts to rears at service intervals etc.
