4 Motion Off Road Wheels Size Difference For Spare?

[Mark Howkins]

Intent - change wheel tyre combination for BF Goodrich

If changing the wheels/tyres on a 4 motion - do I have to keep the spare exactly the same size due to transmission system?

4 Motion T32 Steels - anything I should consider eg. size, big brakes etc.

2 initial thoughts.
1. A spare is an emergency wheel in this case.. therefore it would be fine to get from A-2-B. I would leave it, if it was me.
2. If you also upgrade your spare, will it fit in the carrier?. If not then it a whole new concern.

T32 will have the larger brakes.

You should have a spare the same size on a 4 motion, if not, use an inflation kit to get you to a tire shop, i'd hate to know how much a damaged driveline would cost.

I have been informed that 225/65R17 All terrain Kumho's fit by Trakka, (Australian Campervan manufacturer)

So the 225/65R17 KO2's should in theory fit, i do plan on fitting the Ko'2 in the next 3 months

I run over sized tyres 235/60/17, but my spare in OEM 235/55/17.

My thoughts are, if one tyre were under inflated by 10psi or so, it would amount to the same situation, and that would be absolutely fine in terms of 4 motion.

So I keep the OEM spare, and maintain it at a high pressure, I'm 99.9% sure it is fine

Ditto - BFG 225/65/17 fro me too. I just need to decide on refurbished Satin Black Steels or new New Satin Black Alloys, price difference is only around +200 for new Alloys, or +800 for the Rhino Warlords!!

I like your theory, in addition rolling speed of all wheels will be slightly different for all wheels dependent on road/terrain/cornering.

@Dannyb6467 has same set up.

They are my factory 17 inch T32 steels that came with the van, the powder coater sand blasted them and powder coated them in Satin black for me.
