If you're going to be doing a lot of loader work in dirt then yes ag's will provide you with better tractor. There is a great debate over ag's versus the wider R4 industrail tire. Both tires have their place and benefits. Alot of people love the ags for loader, grading and tilling work. Other people say the R4 industrail tires work well for minimal impact on an established lawn and wont tear up as bad as ag's will. If you're working on a budget then ag's are more affordable over R4's
