Q: Will 20-inch wheels ride worse than my stock setup?

Not necessarily. Twenty inches keeps meaningful sidewall, so ride comfort stays reasonable on imperfect roads, and the lighter forged construction actually helps the dampers stay composed over broken pavement. You trade a small amount of cushion for sharper response and lateral support. Most owners find the balance better than stock, especially on the square 255/40R20 setup that prioritizes comfort and even wear. If you want more stance and grip, the 21-inch UP-05 package steps it up with a firmer edge.
