Tires that came with the car were very much worn so I immediatelly had to buy 2 new sets: summer and winter tires.

I have in my possesion original 15-inch rims from Opel so tire sizes are also factory standard.

Summer tires

Size: 205 / 55 R15

Model: BFGoodrich

Type: ProfilerG

My opinion: I just bought them so I can only say that they cling well on turns :)

Winter tires

Size: 195 / 60 R15

Model: Fulda

My opinion: Good grip during acceleration and breaking, good water draining, but doesn’t hold so well on snow in side winds. I had such a situation: driving on a snowy road, over open terrain, I had to counter the steering wheel to keep on the road while cars in front and behind me did not have this problem. Although my general opinion on these tires is good since this type of situation is quite rare and one can always simply slow down :)
