Spare wheel size

[Nath69]

Hi All

I'm in Australia looking at buying a 1999 2500 LT 4x4 turbo diesel Suburban as my tow car.
Only reason being we don't have many 7 seat 4x4 wagons that have a pay load over 600kg. When I'm loaded with kids, surf boards bikes and caravan on the back, I'm well over the legal limit in my current car.
I have done plenty of research and have a long list of modifications I would plan on doing to it.
One question I'm hoping to solve is how big a spare tyre will fit in the back as I'm would be looking at going to 33" or even 35" all terrains.

Thanks

if you do a search you will find that 35" is a very tight fit and may not work. The 33" should be no problem.
