Pirelli sf3 tires are well-priced and offer a great balance between quality and cost.
They perform very well on both dry and wet roads, good noise levels and they are fine on snow roads.
I recommend them if you want a single set of tires and don't experience very harsh winters where you live.
If you face harsh winter conditions, winter tires are recommended.

The most recent owner reviews fitted in this size, in their own words.
Chinese rubbish don't waste your money, these tire ruined in handling of my car in all conditions both wet and dry. I took them off my car after 3 weeks .Pay a bit more and buy a European brand.
After 45 000 the Tire on the inside was cracked all around. The outside of the Tire was perfect. Tread left was 7mm. This to me was unacceptable my dodge tire set is Parkour pk07 tires and they are exactly the same size as they were purchased 4 months earlier 59000 Tread left 6mm but no cracks no defects.
These came with the car as I bought it, and under any significant degree of sudden acceleration, the wheels spin in even the mildest of damp road conditions. About 50% of the times I enter a roundabout they spin. These tires are dangerous, and I highly suggest avoiding.
Replaced the Goodyear's who wear worn for a new set of vorti's on the front.
Great tire! Good feedback en low noise. Tires gives a save feeling on wet and dry. Cheap in comparing with other first class brands.

Only had these on our Volvo S80 2.5t se sport good mix of roads, single, double and motorway. Nothing wrong with the tires performance wise just the wear is horrendous, they have only lasted 6 months! on the front the rears are still good and should last another 6. I have used Avons on all my other cars but sadly they are not for the Volvo.
Running an Audi A5 Cab S-line. Dry grip is fine, better once tires are warmed up.
Wet or cold grip is well under par. Pure lack of grip and confidence.
Now I thought this was due to the s-line suspension but not the case. I changed over to Mit MXTs which offer much better balance for UK roads.
No rim protection at all, If you want this tire, I'd suggest going to the max width of your nice alloys for protection
