Ya your tire is about 2" shorter (little less) than the tire he wants (30.04" compared to 31.9"). What year Rodeo was it? I wouldn't say ground clearance but larger wheel wells (but sure the VX has more clearance too, stock listing is bout .5" more than a 99' Rodeo), I know my 1st gen Rodeo had much larger wheel wells than the VX but the 2nd gens (98 and up) have tiny wheel wells. They need so much trimming for larger tires than stock unless you suspension lift AND body lift and don't wheel it much lol
