I had to put on my spare wheel today due to a dredded puncture. I think its the wrong size, i mean i know its a different rolling diameter to my other tyres because its throwing my torque gauge on permenently which cant be good, and its also making my car shudder so much which could be due to being off balance.

Anyway my tyres on the car are 225/50 R17's

My space saver reads T125/90 D16

Now i presume that its basicly the same measurement system the 125 means width the 90 means profile and the D16 is the size of the diamter of the rim

Now would i be right in saying that because the rim dia is smaller by an inch my profile should be bigger by an inch making that a profile size of 60 not 90.

just need confirmation of what size my space saver my car should have whit my tyres?

Thanks

the 50 and 90 are a % of tyre width

See here - it is called aspect ratio

So how do i find out what size my spare should be so its the same rolling diameter as my other wheels

I'm pretty sure space saver tires are not available in Aus so try not to wear it out if you can help it. When I get a puncture I get my wife to bring me a whole set of rims/tires to drive home on. I know that someone is going to come in and say that they are available but I have been to many tire places and no one imports them anymore. I can't see this differing from state to state.

I did a comparison between my stock 17inch alloys and my space saver today and theres 30mm difference which explains alot why my torque gauge if going of its nut, not good for the system. Maybe it might be worth me seeing if i can get on off a falcon or something that has 17inch rims and would have a 17inch space saver. otherwise im stuffed if i get a puncture anywhere.

I just factor in a tow if I get a punture haha, I like the idea of a spare from a lager car hhhmmm maybe ford wreckers? Also is your space saver on the front or the back? I think it would cause less of an issue on the front though I have never tried it.

yeah but it would be a pain in the but getting towed if i get a puncture, i like to be able to get these situations sorted myself but if i cant get a spare sorted out i might have to enquire about getting a racv membership cause i know they give you free tow if your car breaks down.

As for the ford wrecker im not sure even if the falcons have space savers, im pretty sure they do but not 100% and i bet you if i find one that it doesnt have the correct size tyre on it. So that leads me to trying to source a tyre which could be a mission in itself as when i got my tyre back from the tyre joint today i asked about getting a space saver and they said you cant buy them, go see the car manufacturer.

I imagine that the tyre being on the front would be less of an issue also being that the front diff doesnt actually engauge unless your back wheels start to brake traction. Not sure about that though cause they do require a 4wd dyno and when you have them on the dyno all the wheels spin.

Can u check what size ur space saver spare tyre is cause mine is the wrong size and im wondering if they are all the same, cause if they are nissan sux. Its a pain in tha arse.

its only a temporary tyre to get you out of trouble....get to a tyre shop for a proper solution

I realise that and its fixed, but i dont alot of driving around Australia and i dont want to get stuck somewhere where i cant use my spare. The only solution a tyre shop can give me is to buy another full size wheel which isnt really an option as i will lose the room that i need in the back of my car, hense the posts to try and get this sorted.

OK so my space saver is a E-08A T125 / 90 D16

hope that helps

And I hope I never have to use it, it looks to small to go on my mountain bike let alone a awd wagon

yeah same as mine mate, i had issues with using mine the other day hense why im asking. f**kn nissan, hopeless. The least they could do is make a space saver that works and wont cause damage to your car. They have thought of everything else when designing the stag.

I booked my trip at the end of the year so we will have to catch up.......

Spare in a bottle?? I know it's not the ideal solution, but at least it will keep the rolling diameter consistent: a new tyre has to be cheaper than repairing a fried ATTESA system....

Spare in a bottle? what do u mean? id rather walk home and pay for a tow truck than use my spare.

The aerosol sealant that you find at autobarn/supercheap, etc: seals and inflates a puntured tyre, but the repaired tyre is pretty much a throwaway... Pretty sure some manufacturers were supplying it instead of a spare tyre for a while...

    • This has clearly gone off on quite a tangent but the suggestion was "go standalone because you probably aren't going to stop at just exhaust + a mild tune and manual boost controller", not "buy a standalone purely for a boost controller". If the scope does in fact stop creeping at an EBC then sure, buy an EVC7 or Profec or whatever else people like to run and stop there. And I have yet to see any kind of aftermarket boost control that is more complicated than a PID controller with some accounting for edge cases. Control system theory is an incredibly vast field yet somehow we always end up back at some variant of a PID controller, maybe with some work done to linearize things. I have done quite a lot, but I don't care to indulge in those pissing matches, hence posting primary sources. I deal with people quite frequently that scream and shout about how their opinion matters more because they've shipped more x or y, it doesn't change the reality of the data they're trying to disagree with. Arguing that the source material is wrong is an entirely separate point and while my experience obviously doesn't matter here I've rarely seen factory service manuals be incorrect about something. It's not some random poorly documented internal software tool that is constantly being patched to barely work. It's also not that hard to just read the Japanese and double check translations either. Especially in automotive parts most of it is loanwords anyways.
    • If you are keeping the current calipers you need to keep the current disc as the spacing of the caliper determines the disc diameter. Have you trial fitted the GTS brakes fit on a GTSt hub or is this forward planning? There could be differences in caliper mount spacing, backing plate and even hub shape that could cause an issue.
    • Hi there I have a r33 gts with 4 stud small brakes, I'm going to convert to 5 stud but keep the small brakes, what size rotor would I need?
    • First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist.   So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else.   The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.
    • How complicated is PID boost control? To me it really doesn't seem that difficult. I'm not disputing the core assertion (specialization can be better than general purpose solutions), I'm just saying we're 30+ years removed from the days when transistor budgets were in the thousands and we had to hem and haw about whether there's enough ECC DRAM or enough clock cycles or the interrupt handler can respond fast enough to handle another task. I really struggle to see how a Greddy Profec or an HKS EVC7 or whatever else is somehow a far superior solution to what you get in a Haltech Nexus/Elite ECU. I don't see OEMs spending time on dedicated boost control modules in any car I've ever touched. Is there value to separating out a motor controller or engine controller vs an infotainment module? Of course, those are two completely different tasks with highly divergent requirements. The reason why I cite data sheets, service manuals, etc is because as you have clearly suggested I don't know what I'm doing, can't learn how to do anything correctly, and have never actually done anything myself. So when I do offer advice to people I like to use sources that are not just based off of taking my word for it and can be independently verified by others so it's not just my misinterpretation of a primary source.
