Yamaha does in fact make their newer Quiet Tech carts such that the tires wear out faster (when primarily driven on pavement). Alignment consists of caster, camber, and toe alignment. Yamaha purposely makes carts factory set with negative camber, which improves handling/stability. I suspect they do this to make their fleet carts more stable on the uneven grassy terrain of most golf courses, which is the biggest market for their carts. In my opinion, they should make their personal transportation vehicle line of carts, which are primarily driven on pavement, with a different factory camber alignment more appropriate for road use than on grass. Most likely to keep costs low, Yamaha has chosen to make both lines of carts with the same front end components. Unfortunately, there is no easy camber adjustment without replacing the front shocks with aftermarket shocks specifically designed for camber adjustment.

On another note, my BMW sports car also came from the factory with noticeable negative camber and the manufacturer’s suggested alignment is to not change it. It wears the tires faster, but it adds to handling/performance which is what the car is designed for. It also has wider rear tires than front tires, another performance feature for a rear wheel drive car, which shortens tire life because you can’t rotate them.

IMO difference in 8” tires vs 10” tires.
