Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Very top quality tire from Turkey (same country where my brother's Case farm tractor is made). Thick rims and deep treads. Tubes are good quality with hard plastic valve and base. Not too hard to mount with tire irons if you're patient and like to do it yourself. I own a big Kubota M Series plus a smaller Belarus tractor and these tires are as good or better than the original stock ones that came on my previous Kubotas.
