The front rims are marked: Offset 30. 18x8JJ FRONT.     3.1822 FRD.      CD100 FZ32.    Tyres are 225/45R18

the rear rims are marked:   Offset 30.  18x8JJ REAR.        3.1823 FRD.      CD 110 FZ 32     Tyres are 245/45 R18

What is different between the front and rear rims  as I have measured several dimensions and they seem identical?

can a rear rim be used safely on the front? And vice versa...

hope someone has the answer as I just bought what I thought were two fronts but have actually been sent one of each!!

cheers Mickel

Cars all over the world are frequently having the wheels rotated front to back to even out tyre wear. I'm thinking a front rim and rear rim is something like a right handed and left handed screwdriver. 

You didn't have to measure your rims, they are both 18 inches rims, 8 inches wide with a 30 offset. What were you measuring when you were trying to find discrepancies between the rims?

Looks like the only thing you need to sort out is a matching set of rubber for them. 

But if this was just a troll post, good job mate you got me.

No scam Murray"...........so why are the wheel rims stamped rear or front?

the owner's manual refers to different tyre sizes front to rear but doesn't explain anything about rim differences.

This is the famous "why is there a stud that stops me putting the rear wheel on the front?" question.

There is no functional difference except for the tyre size. Nissan put a little stud onto the rear wheel so you couldn't put the fatty on the front, is all. Stud is easily removed, problem goes away.

Thanks for the response GTSBoy, I looked over the rear wheel for the stud but couldn't see one on the rim. Where is it found? Both rims have 225 tyres on them so perhaps the stud was removed by the previous owner?

That would be the logical conclusion and the point to take from my reply.

Google up the search terms - or search on here. Multiple threads on the topic.

Each pair of the wheels are probably from a different batch or a different time when manufactured

Nah. The CD100 and CD110 codes on them are for front and rear. On other similar era cars from the same chassis types, Zs and V Skylines) that had different tyres front and rear, there was also codes like AL400 and AL410. Exactly as I described in my earlier response to the thread. They are different wheels, but only because of the stud to prevent you putting the rears, which carry a fatter tyre, on the front. Seems like a stupid solution to a stupid problem that didn't have to exist. But this was when Nissan was beginning to suck.

      🚨 Need Advice! Overcharged for Engineering Report 🚨

      By GTSBoy · Posted

      This is actually 2 whole different trains of thought that need to be addressed separately. No, as Matt says above, "Engineer" is not a directly protected title. A lot of guys who just do mechanical design via CAD, with or without even some sort of associate diploma in engineering, often have the job title of "Design Engineer". A train driver can probably still describe themselves as an engineer. But, to usefully get employment with anyone as a proper engineer, you're going to have to have at least the necessary and relevant degree qualification. You're not going to get a job as an electrical engineer if you have a chem eng degree, unless you can demonstrate x number of years of working in that capacity, sufficient knowledge, etc. Having the degree is at least in indication that you've seen the relevant text books, even if you haven't read them (like pretty much the last 10 years of graduates!). To be a self employed engineer.....you could get away with quite a lot pretending that you're suitably qualified, without actually being a proper engineer. But, you will find yourself unable to work for a large section of the client space because a lot demand CVs and capability statements when considering contracting for any engineering work these days. Insurances too. If you're not a proper engineer, it will be much harder to obtain proper PI insurance. Insurance companies have gotten hip to that. The "Professional Engineer" thing is a thing in Australia. If you have the right qualifications and experience you can apply to the relevant engineering top level body (mostly Engineers Australia, the less said about whom, the better), to be assessed and approved as a Chartered Professional Engineer, CPE. There are high bars to get over and a requirement for CPD to maintain it. The RPEQ thing is similar-ish, in that you have to demonstrate and maintain, but the bars are a little lower. It is required to be RPEQ in order to sign off as an engineer on any engineering design in Queensland. The other states haven't fully followed suit yet. There's "engineering" and there's "engineering". Being an engineer that signs off on timber (or even steel) frames for housing projects, council creek crossing bridges, etc, is a flavour of civil engineering that barely warrants the name, description and degree. That would be soul crushing work anyway. Being an automotive engineer working in the space where you have to sign off on modifications to cars and trucks would also be similarly soul crushing. At least partly because of the level of clientelle, their expecations, depths of bank balance, etc. And that brings us to your second question. No, we do not have professional engineers "do vehicle inspections". Well, not the regular roadworthies, etc etc. That's done by mechanics. There might be some vehicle standards engineers at the various state govco inspection stations where cars go to get defects cleared and so on, but that's because they (the cars) are there specifically for defect inspection and clearance and so the stakes are a little higher than on an annual lights and brakes working check. But, if you modify a vehicle in Australia, you have to get it engineered. A suitably qualified (and effectively licensed, which I will get back to) automotive engineer will have to go over the application, advise on what would be required to make the mods legal, supervise some parts of the work, inspect and test the results, and sign off. The "licensed" aspect comes from there being a list of approved engineers to do these things in each state. They have to jump through hoops set up by the govco vehicle standards divisions that mean only the suitably qualified can offer to and approve such mods.

      Meh, it's only got to last another 10 years or so until you'll be forbidden to drive it. Keep it dry and forget about it.

      The title of Engineer is not protected. However different states have different rules about what an Engineer requires to operate. Engineering for a motor vehicle modification is very different to engineering for a bridge, electronics, etc, including what that engineer needs as certifications.   In Canberra, "Engineer" is the loosest category with basically nothing stopping you calling yourself and engineer and designing a bridge or building. From what I've reviewed, QLD has the strictest requirements through RPEIQ.
