noob question - don't read unless you want to help
sorry...
but i don't understand the whole offset rim thing..
I've never bought rims...but consider our rims look too similar to the RSX and TSX rims, I want to change them to something a lot nicer...especially cause if I'm buying tires for like..5 to 600 bucks....might as well just spent a a little bit more...and get rims included with tires....so anyways..i'm looking for those black anodized rims with the chrome lip...probably 19x8.5 in back and 19x8 in front...but then i don't know what i can do to prevent rubbing and so that it'll fit my 6 speed MT with the brembos....
sorry for such a noob question. thanks for your help. sorry if repost, but all the other offset questions doesn't read like it's for noobs like me..

search the forum for "offset" and/or "backspacing"
each is a differnt #, but they both measure the same thing.
look at a rim width-wise, place a vertical centerline right in the middle (width/2). now, from that centerline you measure to the mounting surface face. if you place the rim in the left front spot and look at the rim from the rear, if the surface is to the left of centerline that is + (positive) offset, if it's to the right then it's - (negative) offset. increasing + offset will move the rim further in under the car, decreasing + will move it out (positive or negative just means what side of centerline it is). so a decreasing +, say +42 to +40) means the rim moved out 2mm. you won't be buying negative offsets.
offset along with the rim width #'s and tire size will dictate any rubbing issues.
i suggest same rim width on all 4.
hope this helps.

sorry...
but what do all these numbers mean..
19inch-------> 19x8.5 40et w/ 245/35-19
19x8.5 is the rim size by width
40 et = no clue?
245/35 = tire size?

40 is the offset.
245 is the width of the tire.
35 is the profile (i.e. the thickness of the tire). Since the "35" is a function of the width of the tire, a 245/35 tire will be a higher profile tire than a 235/35.
edit:
Here is a much more detailed explanation that I could ever provide. It is from Tire Rack.
