Kia Optima parts reviews

I recently purchased a set of 4 Toyo Celsius 2 tires for my 2019 Kia Optima. After living with them for a couple of days, they're good but they have a couple of weird quirks.

Pros: Pretty quiet, great snow/ice traction, soaks up bumps great.

Cons: The compound feels unnervingly soft, to the point it feels like it's running on low pressure (it's not). As a result, I feel like dry handling takes a big hit. I can't speak much for MPG but because of how soft the tires are, there seems to be a lot of rolling resistance.

Depo would probably improve on the design. Me and a lot of fellow Optima owners have burnt headlight bowls.

On our prescribed sighting-lap line, the Optima's chassis proved compliant while the standard high performance dampers (fundamental design shared with the Sorento's dual flow dampers) and suspension tuning found a good compromise between a relaxed ride and more aggressive roadholding. Off the driving line, the stock Nexen touring tires didn't enjoy steering corrections at speed, and predictably squealed in protest.

I would suggest the genuine Kia one, or a professional grade like NAPA's top line or an AC-Delco. I would avoid anything that says "USA Industries" or "Duralast" on it, based on personal experience. In our shop we have had nearly 100% failure rates with those brands.
