Im looking to get new rims but i dont know much about wheels.

I currently got the stock 16s on and looking to get 18's.

The 18s im looking at is: 18x8 +35 5x112

Now the stock 18's u can get are : 18x7.0 +43mm

is the 18s im looking at the right ones?

Also are 235/50-18 the right tire size for the 18's too?

Thanks
