What does narrower tires do to your ride quality?
I made a short video on the matter to show what can you do with your ride just by changing the wheel and tire size. There are many good options other than seen in the video if you like bigger size wheels look wise. The key here is the width of the tire if you want softer ride.
If your tire flexes more you can make your car ride softer with narrower tire. Like most people think suspension is too hard with the stock Model Y 255/45R19 tires.
Or if your ride quality is good to your liking if you bumb more pressure to your narrow tire and it will still have similar ride harshness but less rolling resistance.
Here remember that tire will have less grip if you bumb pressures up. So do your own testing what is the limit of grip you need. Its not a easy puzzle and everything impacts everything. even the smallest changes can have big impacts to your cars behaviour. Do remember that in evs the tires are not wise place to save money. buy good brand tires or ones that have got good reviews in tire tests.
Many people complain tire prices and specially with winter tires. If you put smaller size wheels and tires you can even halve your tire costs when purchasing them.
