It's not about the dealer ....it's about what you need to use your feet for.
Google, "4x4 Tyre comparisons" and go from there.
Then find the best price for what you NEED based on your research.
From my experience all warranties are based on the manufacturer(however are all superceded by http://www.consumerlaw.gov.au/content/Content.aspx?doc=home.htm ...prices are based on the dealer/agent.
Hope that helps.
