The width determines if the tire will fit OK on the rim, if it will fit OK in the wheel arch, and the amount of traction it can offer. A car that gets too much traction can flip instead of slide when turning hard, which is more dangerous.

Which tire is bigger a 30x9.50R15 or a 225x70R16?

Which Tire is bigger you ask? The 30X9.50r15 is larger than the 16 in tire in width. To get the width of the 15 inch tire you need to multiply 30 by 9.50. This will give you a total width of 285. So the width of the 15 inch tire is 285mm wide. The width of the 16 inch tire is 225. So there is a difference of 60 mm. I am not familiar with the Jeep Cherokee. I have seen a few people place 255/70r/16s on their jeep cherokees. I think 285 mm wide tires might be a little too wide. If you decide to lift this jeep, then you should not have a problem placing a 285 mm wide tire on it.
