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.

I am currently running Work Cr Kai 18x8.5 +43 on Achilles ATR Sport tires 235/50/18 with KW V1 coilovers. I am having a bad ride issue and I was thinking of downsizing to a 17" wheel but I am unsure on width, offset and tire size. I am pretty much flush right now and would like to keep that look but in a 17" package. Suggestions?

235/50/18 is very tall, are you sure that is the correct size?

If you want to keep the same wheel fitment, just do around 17 x 8.5 +43 , then use a 235/40/17 tire.

My apologies, 235/40/18. Key punch error!

Why does the OP say that those sizes are for RSXs with no modifications or alterations to fenders etc. when a lot of the wider sizes need the back fenders to be rolled?

This is an excellent sticky!

I just put on a new set of 17x8 wheels with new BF Goodrich Gforce Comp2's 235/45/17's, and although I have a conservative Eibach Spring set with 1.25 inch drop in the rear and 1.00 inch drop in the front, they are still a very snug fit. I did have my rears rolled prior to getting this set up on my car, however, I was not prepared for the front to actually get some minor rubbing when hitting a dip on the freeway/road. Granted, the offset is aggressive with a +25, so the rears are good to go, but the fronts are not. So, needless to say, I have a mobile fender roll guy coming out this Saturday to do the fronts and remove about 1 1/2 inches of the liner to resolve the issue. I knew I was taking a slight chance with the fronts with this aggressive offset, but did not think I was going to have an issue. Although it is minor, it is more than enough to ensure that it is simply wise to get all wheel wells rolled when going with a wider tire/wheel/offset. I just hate that feeling when driving and you start to "cringe" when approaching an unknown dip on the highway and then you hear that inevitable "scheeecht" sound from the tires hitting the unrolled lip and liner..... ugh. But, it will be all good come Saturday and I will be able to drive normal again.

Thanks again for this wheel/tire chart! It has been a tremendous help.

Will xxr 527 18x8.75 +20 with 215/40/18 fit my rsx type s without rubbing or fender mods?
You should roll the rear fenders for sure

Wondering if mb battles 17x9 +30 offset would fit flush without spacers and would be the ideal tire size (not too thick but with good width)

Any idea would be very helpful

Car will be lowered about 1 inch from stock or a little more depending on how the wheel fitment is

Also with mb battles would I need to extend the studs or get longer lugs?

Thank you

what about 17X7.5 45 offset with 215/40/17 tires? I am lowered with skunk2 coilovers. I was thinking either 215/40/17 or 215/45/17

now I am looking at Montegi MR131 Traklite in 17X8 40 offset. What size tire would be closest flush with the rim? 215/45/r17 or 225/45/R17???
I do not want the tire to stick out past the rim and I do not want the tire to look "to narrow" for the rim.

Obviously a very old post, and no I didn't go through all 1,556 posts, but I'm assuming the initial chart reflects how things were almost 20 years ago. I'm looking at some xxr wheels that are 18x9.5 +20. I'm dropped decent, rear slightly tucks 225/45r18. Fronts about flush wheel gap. Should those specs work out for a pretty flush fit with minimum rubbage? I know 18x7 +38 with a 25mm spacer was pretty flush, but I'm unsure how rim width is going to change me up
