Spare tyre size for 76C3

<< < (2/2)

sirfixalot:
The important consideration is the rolling diameter of the spare wheel has to be equal to the diameter of the rear tyre

Philip:
Thanks Geoff. Yes I understand the tyre diameter must be he same as the rear to enable the diff to function correctly.

Vettech:
The spare is a low speed smaller setup as Ray and Geoff indicate.

I'm running OEM Wheels on my 78 - steel rallies, c/w 255's.

These can fit in the spare carrier, since the bolt up bit at the rear can be turned 90° and dropped to a lower position.
AND.
The front two hangers allow the carrier to be lifted, unhooked and also dropped to a lower position.

My STD 255's just fit in, but once the carrier is tightened up, be aware that speed humps are a no go, since clearance now under the rear is very close. (The 255's are a bugger to get into the carrier, esp now I'm old and decrepid.)

Keep in mind that the carrier, cross member, diff/ axle and spare are designed as part of the rear collision crumple zone, and it is highly recommended that the correct spare fully pressurised with air is always in position.

Philip:
Thanks for your info Vettech Ill take it on board. Cheers
