I am in the process of cleaning up some rust and repainting in the rear interior of my 2 door range rover. I have the aluminum floor panel removed. I am just wondering if you guys think there are any really good things to do while I have it removed. other than getting rid of all the rust possible.

I live in Louisiana, No snow, some rain. I need to replace my stock tires. Contenitnal Cross Contact Do anyone suggest i go back with the same or something that will fit my local conditions. i currently ride 275 40R 20. Any sugestions would be helpful. By the way I dont off road.
