These wheels and tires fit perfectly on my used AlumaCar golf cart. AlumaCar is a Chinese knock-off of a Club Car Precedent. The tires are 18x8.5-8 on 7 inch wide rims. It took me maybe a bit over an hour to remove the old wheels and worn out tires and replace them with this combination of wheels and Antego tires.They look great for starters, but more importantly, the ride, speed and handling of the golf cart are so improved it is almost shocking. I bought this cart used, knowing the tires needed replacing. It turned out to be not much more expensive to buy the wheel and tire combination instead of just buying tires and dealing with the cost and hassle of replacing the tires on the existing rims. Even my existing wheel covers fit perfectly.The fit is perfect on the four bolt studs. The studs are three inches apart and I forget the diagonal measurement, but it matched what was recommended. The 7-inch wide wheels are perfect, as wider wheels would have rubbed against the front suspension.With the work finished, I took the cart for a quick test drive. It was like driving a new golf cart. The ride is so much smoother, the steering is lighter and it feels like the cart accelerates much more quickly than it did with the old tires.At just over $200, this was a bargain. I don't use the cart outside our certified golf cart community and no high speed driving, so they serve my needs perfectly. I couldn't be happier with the the purchase. Only time will tell how well the tires wear, but for day one, I am totally happy with these.
