Hi Sam and yes I've tested it.

https://www.aulro.com/afvb/images/im...016/06/277.jpg

The diameter difference is 12mm (smaller) for the 255/55 R19 compared to 265/60 R18 assuming equal tread and equal pressure. In reality, the difference will be less because the 18's will be partially worn and the 19 is brand new, never used (original spare). So the most likely diameter difference would be around 6-8mm, possibly further reduced by maintaining higher pressure in the 19.

I tested this wheel combination without reducing pressure in the 18's around my local streets for a few km's. I would expect going around bitumen corners a few times to be a good way to get errors if they were going to happen.

Also, I've read on the forum of someone (garrycol) running a 255/55 R18 in combination with three 255/60 R18's from Melbourne to Canberra without issue and that's a diameter difference of 25mm (smaller).

In any case, this is an infrequent situation when a 2nd flat has occurred before the first is fixed (noting the first spare is a GOE 18). It's not a long term solution but I don't expect problems with such a small diameter difference.

Cheers,
Scott

Glad I found this topic!

I'll be ordering some GOE rims soon and the big decision is whether to get 4, 5, or 6 rims.

In the context of all the other things I'd like to buy for the car, my preferred option is to keep costs down by buying 4 GOE rims and carrying OEM 20" rims as spares. One spare for short trips, 2 spares for longer ones.

My main concern with this configuration is difference in tyre diameters and the potential problems that might cause. It's great to hear that you, Scott, haven't had any issues. Can anybody else comment on this from experience?

Ultimately I decided it wasn't worth the risk. I have 5 GOE rims and a LR 18" rim that will fit the rear, all with 265/60/18 tyres.

Steven, I bought 5 rims and only carry the OEM as a 2nd spare.
While the slight mismatch in overall diameter is small, I still didn't want to rely on that exclusively.
Not sure what tyre size you have on the 20" to compare overall diameter to 265/60/R18

PS .... good to see you back

Hey Scott,

Physically I'm still in Mexico, but mentally I'm almost back in OZ. :D

Great video of you tackling the Big Red!

You will kick yourself if you don't buy 5.

Even if you do minimal damage and plug up tyres you can retire one to be the spare, without having to buy new tyres.

My belief always, a set is 5
