PLEASE DO NOT PM ME ASKING WHAT WILL FIT. I ONLY KNOW THE INFO ON WHAT IS POSTED BELOW.

RSX Wheel Offsets and Tire Sizes.

All sizes and offsets listed below are known to work and have been used by a member here. Another tire size or offset may work than those listed, if you have used or are using an offset and tire size that is not listed below, post a reply to the thread and I will try to add it. Please be sure you know the offset works before posting and pictures always help too.

Shown below is a list of wheel sizes, offsets, and tire sizes known to work with them. All of the information below is based on RSXs without widebody kits and unrolled fenders. This way everyone will have an idea of what works on a stock body, lowered RSX. Also, these sizes are without the use of wheel spacers.

I hope this helps everyone...

-Offsets, Hub-Centric Rings, and Counterbores-





Basically offset is the distance from the centre of the wheel to the part of the wheel that sits against the hub of the car (mounting pad), more commonly measured in millimetres (mm).

As you can see in the diagram above, a positive offset is when the mounting pad of the wheel is toward the outer edges of the car and a negative offset is when the mounting pad is towards the centre of the car more. An offset of zero is the absolute centre of the wheel and would have an equal distance to each side of the mounting pad. For the RSX all of the offsets should be positive (+) I don't see where you would want or need to use a negative offset at all. The offset will change on wheel width too, you won't have the same offset on a 9" and a 7" wide wheel and have them fit the same on the same car.

When you buy aftermarket wheels the centre bore of the new wheel will be much larger than that of the stock wheel, this is because of the wide range of hub sizes on different cars and not all cars are made the same. So what the wheel manufacturer will do is make the hub size the largest so it will fit over any hub and then a hub-centric ring must be used to make up the difference between the RSX's stock hub size and the aftermarket rim center bore size. These are usually made of plastic or aluminium and should come with your new wheels to prevent any vibration that may occur. Without them, your wheel will not be truly centred on the hub and at certain speeds, your steering wheel may shutter and/or vibrate, just like an unbalanced tire - not a good feeling.

17x9 +28. Since it's only a few mm off of the typical +35 RPF1 size, +28 should fit fine right? Planning on either a 245 or a 255 tire, not sure yet. I know I'll need the rears rolled for sure, run a little bit of camber, but other than that the fronts should be fine right, no need to remove fender liner?

Please add to the list even though its 8 years old.

235/40/18 tire will fit a 18x9 +30 rim no body mods or camber, flush with body
225/40/18 tire will fit a 18x9.5 +22 slight stretch with -2 degrees camber, no body mods required unles you want to.
235/40/18 tire will fit a 18x9.5 +22 no stretch with -2 degrees camber, no body mods required unles you want to.

Just some info for you crazy wide rim fans.

The tire should look good on the rims, but you might have to camber that +27 rim slightly. If the +40 is going on the front I'm thinking you might have to run a spacer, to clear the suspension. Not sure though. But regardless the tire will look almost light my tires in the picture but with the side wall with a very slight stretch to it.

i dont know if this is the right thread.. :D

what hubcentric rings are you using? aluminum or plastic? i bought mine in Wheel Works but its not that tight.. its hella loose..:rolleyes:

mine looks like this (got it from the tire shop "NO BRAND")... same as kseriesparts but not (ENKEI)


from kseriesparts


this one is plastic but it has clips..


or the aluminum? do they hold onto the rims?



metal? do they hold onto the rims?

I run hubrings since they came with the wheels and supposed to be more stable. Didn't even get them rebalanced and no vibrations or shakes at 85+mph. The lugs center the wheel so I don't think I would even need them.

18x9 +35 ???

I am considering getting some wheels that are 18x9 +35 paired with either 235/35/R18 or 245/35/R18. Will this fit with no issues or modifications?
I have an '06 with an A-Spec drop. I don't plan to go any lower and don't want to add any camber. I wouldn't mind rolling the fenders if necessary. And I don't want stretched tires.
I know you guys usually recommend taller sidewalls, but the online calculators say that 35 will keep my speedo accurate.
