This what fits and what hits could be broken down into 2 simple measurements. "Backset" distance from the rim mounting surface to the back edge of the wheel including tire bulge. The other measurement woud be from the rim mounding surface outward to the front edge of the rim including the tire bulge.
Tell me what back set just rubs a bit and what outward measurement just slightly rubs and I would be able to stuff one impressive tire under that rsx. I am sure some yrs have different measurements so that must be considered.
Camber must be at a stock setting or noted with measurement
All that is needed to do this calculation is a straight edge and a tape measure.
If some one could supply these 2 measurements to us we all could do the figuring on our own.
Going to stuff a 245/40/17 on an 8" rim under my RSX once I can get those measurements
Thanks in advance,

But this calculation "including tire bulge" would have a different measurement every time unless everyones tire size and brand were the same. The tire bulge would be different on a 7" wide rim than it would be on a 8" wide rim of the same size tire. And different manufacturers somehow have different tread widths for the same size tire. For instance, my old Toyo T1-S 225/40-18 measures 9.0" wide on an 8" rim, a BFGoodrich G-Force T/A KD of the same size and mounted on the same width rm comes in at 9.1". One of Bridgestones tires measures 9.2", so its not the easiest thing to go by.

I understand what you are saying though and it still could be done, but there are a lot of variables that have to be considered. If you wanted to you could take your wheel off and set the car down on a jack stand so the suspension would have a "load" on it, and then maybe get a measurement that way.

Nice list, but your avatar scared me with her ugly-ness.

You are right, tire bulge is a variable but not too difficult to figure. Pull the tire size and specification from Discount or Tire Rack table. Section width is given along with the rim width used for the measurement. If the rim is wider or narrower, adjust accordingly

nice thread with some good info
+ reps
now, if more ppl could give their info, like those with large body kits and stuff, it would be awesome

There was question on this forum as to offset. It is the relationship of the wheel mounting surface in relation to the wheel center line. If the mounting surface is exactly in the center of the wheel it is a zero offset. If the wheel mounting surface is between the center line and front edge of the wheel, the measurement is positive.
Hope this helps,

Stock backset for a OEM 7" rim is 5-11/16" Your wheel cal'c out at 6-1/16" Nice if some one could tell you if you could push it back or in another 1/8" to 1/4" and still clear suspension/fuel filler cover etc.
Did not state tire size but imagine the wall will have little or no bulge.
When you do get them installed please let the forum know how much room you have inboard.
Helps us plan our wheel / tire choices

17X8: +35 to +48. Tire sizes: 215/45-17

If I ran the +35 would they stick out too far, my car is lowered on tanabe coilovers.

Would a +47 rub on the LCA? Sorry I tried searching but the offset numbers are too short to search.

should be alright with neuspeed springs?
Okay those I'm sure will be okay with that set up. Only issue I see is putting such a wide tire on a 7" rim. But I believe its been done before and they had no problems.

After a couple hours of reading and searching (lol hard to search since we can't use "35" or "48" as parameters) I found that..

Those who have ran anything +47 or higher and are lowered more at around 2" usually rub the rear inside towards the LCA. Problem can be solved with a spacer though.

+35 will sit very flush with the fender. Its very close to sticking out past hte fender. Although I'm sure it will if you go with anything wider then a 225 tire it will stick out past slightly.
