Check out what best tyres to put on an xc90 thread ....plenty of info on there...
I'm running Pirelli scorpion Verde all seasons at the moment and they will go on next time they're due for change....been on 2 years now,20,000 miles in and still showing 7mm of tread on all 4 corners.
If you're interested see ..........
www.camskill.co.uk...... for all the different flavours but I recommend 107v XL's.
The Goodyear vector 4 seasons are also very good and my missus is running these on her C30 d5 185 se lux.
