Thread: 15" RR rim, about how much, Can I use 16"

If it's only a spare just use a 16 inch rim. Just make sure the tyre you put on the rim is the same or as close as possible to the diameter of your other 4 tyres.

The problem is what would happen if you needed the spare for the front?

You'd have to change the back one to the front then the spare to the back.

Ultimately it's your car, your neck and your licence therefore your final choice but I know I wouldn't be doing it. Especially off road

I could be mistaken here but it wouldn't be the first time.

It shouldn't matter what diameter the rim is, only the tyre. Ok the offset of the rim may play a part too. But if it's just to get you to somewhere to fix the flat one it should be fine.

Also make sure you have wheel nuts to suit the steel rim. The alloy ones are different I think.

These are offroad tyres on the 15inch rims

What happens if you are offroad and get a flat tyre, you change it

Now consider having to air down a lower profile tyre to meet the same profile of the original muddies and travel out of the bush immediately to get the rooted tyre repaired or replaced so you are not risking at least a damaged driveline. I can see potential to even roll the car in this situation due to the different geometry you would have the car set at when traversing ruts etc....

I can see different offsets would give the same result

Thats the way I see it though I am no expert and may just be talking out of my 4r53

Would you go bush with a space saver wheel as your only spare?

You've put a little to much thought into that i reckon, if its around the same size overall diameter it'll do, but not for long distance stuff, like when your crossing the simpson

15" for $90 is cheap , NO ****ING WAY, you can buy a new 15x8 for that

jUST PUT A 265/75/16 TYRE ON THE 16" RIM AND YOU WILL BE FINE, AND AS SAID BEFORE IF YOU HAVE A FLAT ON THE FRONT JUST SWAP A FEW WHEELS SO ITS ON THE REAR.

thanks for all the advise.

The spare would be emergency only and I will get a 15" rim as soon as I can.
Quokka etc
I have good 15" spare tyre, the 16"s are a bit crap but with luck will get me out onto a sealed road at least then if need be I could call the RAC.

I wanted to check I wouldn't bust any diff's etc.
I'll just try and keep the height about the same until I get a 15" rim with a (big) bit of luck I won't need it.
