i am looking at a set of rims and i found these numbers on the specs page for the 18 inch model. i don't really know how to interpret them.

PCD--------9.5 x 18---------8.5 x 18
5/100-------- ------------ ET 32
5/108-------- -------------ET 35
5/110-------- -------------ET 28, 35
5/112-----ET 28,35-----------ET 30,35
5/114,3---ET 35--------------ET 35
5/120-----ET 35--------------ET 15,35

which would be best to put on an 09 accord coupe v6 that originally had the 18 inch stock rims? or would a different size (they have 17 18 19) be better?

thanks.

 

You absolutely have to have a bolt circle of 5 x 114.3mm so there's only one line that says that.

But there's more.
You want the correct center bore diameter, since the rim needs to fit properly on the center part of the hub that sticks through the center hole of the rim. I don't know that diameter.

The "ET" number is the offset in mm. Hondas want something around 50 or so. A smaller offset number will place the tires farther outboard, where they might rub against the fenders. I bet that ET35 is too low, but I'm not sure.

Once you have the rims, you still need to worry about the tire size, so you get the right outer tread diameter & not so wide they rub against something.
