Thread: 18 inch 3.0 wheels.

I tend to keep the spare as a spare only and just replace 4 tyres at a time when needed. Is it feasible to buy 4 GOE rims and keep the oem rim and tyre as a spare with the view that I would replace a busted tyre asap and the oem would resume duty as a spare. I presume that I would need to get tyres for the GOE rims that come close to the diameter of the oem tyres.

Thoughts gentlemen.

If you were going to go the 4x GOE wheels route, I would pick up a LR 18" wheel (or two) as your spares, so you could then use common tyres on all rims. The LR 18" wheel could only be used on the rear axle though (no different to using a 19" wheel as a spare). LR 18" wheels come up on Gumtree etc for around $100 each.

Cost $75 and fits in wheel well no issue. Maybe something to consider.

I have a Kaymar rack on my D3 so I have 6 18" wheels and tyres. The 20" rims and tyres will go on the D3 from the D4 and I will put 4 18 " wheels on the camper trailer (2 for spares) and two on the Kaymar rack once fitted to the D4. If I have a front flat I will have to take one of the GOE wheels off the back. For your spare issue there are plenty of D3 18" rims floating around. They just won't fit on the front.

255/55/19s & 255/60/18s are similar diameter. However, I went with 265/60/18s as a lot more common than 255/60/18s. The speedo is now quite accurate.

Just get 5 GOE rims then you don't have to muck around swapping tyres/rims around.

I put 265/65/18 tyres on the GOE and (deflated) the spare fits underneath.

I think carrying tyre plugs and a compressor are a must so in the unlikely event of a damaged tyre and you need to swap the spare around, then you will have a compressor on board to pump it back up

Main reason for GOE rims is more comfortable ride (my wife has a bad back) with a larger diameter tyre as well as more choice of tyre. My compressor sits in the back all the time and I drive in the city mostly so that wouldn't be an issue. My concerns were about the spare fitting and I have rear air con which may have to be rerouted if I get too large a diameter tyre. BTW what is the issue with fitting the spare under the car? Is it diameter or width or both?

Does that affect the odometer much if at all? Certainly wouldn't mind an accurate speedo for a change.

Martin,

265/60/R18 is close enough to OEM diameter that there is nothing rubbing anywhere and the spare fits underneath without being deflated.
This size also makes the speedo closer to correct as mentioned.

265/65/R18 is a bit bigger again and requires the spare to be deflated to fit underneath. The issue is diameter.
Even deflated it requires a bit of persuasion as its being lifted to ensure it goes up evenly into the wheel bay.
This size gets a little bit of minor rubbing that many report as not a big issue.
I'm not sure about the rear a/c lines for this size. It may be only an issue for the bigger sizes.

I have driven with a single OEM 255/55/R19 together with 3 x 265/60/R18 for a few kms as a test.
There was no errors but over time this would cause crabbing and uneven wear etc.

I'm happy enough to take a 255/55/R19 as a 2nd spare for remote trips but use it as a last resort.
For example, i would plug the first flat if suffering a second flat rather than use the 19.
But if very unlucky and get 2 x unrepairable flats then the 19 would be pressed in to service.

But I wouldn't stuff around with all that for the first spare which is carried all the time (I got 5 x GOE rims).

Cheers,
Scott

The speedo now reads 1 or 2 km over actual speed according to my navigation app.
