Default Will those wheels fit my car.

I got a 2012 lexus is250 AWD.
someone gave me pretty nice looking lexus made rims. The diameter is 19 inch and the width is 9.5 inch. Not really sure how to read the markings in the rims.
If they fit, what is the size of tires I should buy? Thank you all very much.

These look like the stock wheels that came on IS350. Stamping says 18x8,5. Front should be 18x8,0 rear 18x8,5. Check if the other wheels are 18x8,0
225/40/18 8Jx18 ET45
255/40/18 8,5Jx18 ET 50

If you drive AWD then all four tires need to have the same outside rolling diameter.

To make it work with your car the tires should be F: 225/40/18 and R: 255/35/18.
To make things simpler you could do 225/40/18 on all four wheels.

Hope that helps

Thank you very much for the answer

Would it not be dangerous if I put 225/40/18 on all four?

See the note: Generally a width of 7.5" to 9" is acceptable.

You could do 235/40/18 on all 4 corners without issues
