I put the lower profile tires on the front and the 65's on the back and picked up about 2mph on my wifes cart.
The 10" low profile tires are not any taller then the stock 8" tires that are normal sized on carts.
The 65 series are taller and will not fit all carts. In order to have them on my 2005 Yamaha I would need a small lift kit for them not to rub anything.
I paid about $65 each for new 10" 65 series mounted on white rims.
I also prefer the ride on the 65 series compared to the low profile tires.
