I'm an idiot. Let's just get that out of the way up front. I bought an Evo X MR back in July. I didn't want to deal with the huge hassle of parking it somewhere out of the way during the winter and buying a second beater, so I asked the service guys at the dealership about getting a set of snow tires. One of the sales guys heard I was looking for a set. He'd just had a kid, and I guess the wife made him get rid of his Evo, (I assumed an Evo X GSR) so he was looking to sell his never-used snow tires. I happily agreed to buy em off him, and I didn't bother to check size because I stupidly figured, "Hey, basically the same car, so of course it'll fit." Yeah. I'm dumb. The MR, of course, has those huge Brembos up front, and he was selling me 17" tires.

So I'm now stuck trying to sell off a set of snow tires and 4x Kosei K1 17x8 rims. (Pictures of the back of the wheel on the eBay listing, though you probably can't glean much from them.) Problem is, I can't tell for sure what the bolt pattern and offset are from the back of the wheels. I think they're 5x114.3 and +35 offset, but I'd really like to know for certain.

The back of wheels lists three different bolt patterns: "5H-100", "5H-112", and "5H-114.3" And the offset on the back of all four wheels is barely readable. Says, "OFF+3_" where the last digit is obscured by excess metal. It looks like a 5 but I really can't tell for sure. Might be a six. I thought it was an "F" at first, but then realized that made no sense.

Is there any way to be 100% sure of what I've actually got? I don't want to tell someone something, and then have them try to install it on their vehicle only to discover it won't fit because I told them the wrong numbers.

I did measure the bolt pattern with a measuring tape, and it looks very, very close to 114.3, so I'm pretty confident that part is accurate at least.

Any help is appreciated.

 

If the studs on your wheels will fit in the holes, then it's 114.3 (even if they won't go all the way on because of the brakes).

I don't think that Mitsu makes those other sizes.

As far as offset, you're going to have to measure, or find out what width the wheel is, and see what the manufacturer made in that width/bolt pattern and made an educated guess.

 

if they came off of an evo, they are 5x114.3. id say +35 sounds about right, i wouldnt worry too much about that, as it wont be a big deal if your 1 or 2 mm off.

 

And they must be from an old GSR, the new GSR has the same size brakes as the MR and 17's would never fit.

 

Measuring offset is actually not as hard as people think. It is, though, harder with tires on, I believe you could still do it in a few minutes. Basically, you want to try and figure out the different between the centerline (the direct center of the rim) and the hub face. If those rims are x8, then the overall width is actually x9 (it includes the outer lip from either side at 1/2inch each). So, the center line should be 4.5inches. An inch is 25.4 mm, so multiple that by 4.5 and you'll get the centerline in mm (something like 114mm). Next, measure the hub face to the back of the wheel, but make sure to measure across the diameter of the wheel with a flat surface, not including the tires. Subtract that amount by the centerline, and you'll have the offset.

If the centerline is 114mm, and the hub to the back of the wheel is 75mm, then your offset would be +39. Unfortunatly, this doesnt give you the face type, so figuring out brakes could still be a problem.

If it sounds too confusing, because I suck at express thoughts through the internet, theres a bunch of rightups all over the web.

 

Hey, thanks. I think I understood that.

 

Does that still hold true for older Evos? Assuming i8fizh is correct, my assumption about the wheels being off an Evo X GSR must be wrong.

 

if they came off of any evo(8 9 or 10 at least), they are 5x114.3. call the guy and ask him the specs man

 

^ +1 yeah, they all had the same bolt pattern, 5x114.3, however I don't think anyone has been able to find a 17in wheel that will clear the brakes on a any X, GSR or MR.

 

 

^+1

 

Bolt pattern takes 3 seconds to find out and they didnt come off any X.

Learn this picture and decide how ever you want to measure offset, it isnt hard.

 

Did he not tell you they were 17s when you agreed to buy them? Take them back and shove them down his throat.
