w202 | rims bolts and tyre

[badaboum]

Guys

I have a w202 featuring 15inch rims and tyres.

I have bought 16inch ones from a sport version

They are 7J 16 H2 ET37 5x112

They are basicaly compatible with my model

2 questions :

My actual bolds are too short. They are 50mm long. What lengh should i buy for those rims?

What type of tire those rims can handle?

Here they are on another car:

THanks
