Does anyone know of a good thread/reference for what tires fit/recommended for both 16'' and 18'' stock rims? I've got both sets of rims, but am thinking of goin with 275/75R16s (which I assume will fit my stock 100 no problem). Also, what is the biggest tire that fits well in a stock 100? Could you go up to an 80R16? But any reference/recommendations would be greatly appreciated. Thanks in advance.
