I presently have 225/55 R16 tires on my 2003 Mustang Deluxe Convertible. I am looking for larger (Maybe17") and much softer riding, Summer tires.
Also, are there and rear shock absorbers recommend??
Going from 16” to 17” wheels will firm up the ride as you are reducing sidewall height. So even the softest 17” tires (which generally are touring style tires not summer performance) will still be firmer.
