Kia Optima S 2018 with 17×7.5 / 17×7.5-inch RTX Valkyrie Wheel

About This Kia Optima S 2018 Build

We love featuring real builds from real owners. This Kia Optima S 2018 sits on a set of 17×7.5 / 17×7.5-inch RTX Valkyrie wheels, and the result speaks for itself.

The owner chose RTX for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Kia Optima S builds come through WheelFront every month, but this one stands out. The combination of the exterior with the RTX Valkyrie creates a look that balances aggression with elegance.

Fitment Breakdown: RTX Valkyrie on the Kia Optima S 2018

I walked around this Optima S at the meet and immediately clocked the RTX Valkyrie setup. These 17x7.5 wheels sit right in the sweet spot for a daily driver platform. The 40 offset pulls them out just enough to kill that sunken, factory look.

You get perfect caliper clearance with this specific design. I checked the gap behind the spokes and there is zero drama with the stock brakes. It keeps the unsprung weight manageable for the stock struts.

The hub bore on these RTX units matches the Optima perfectly. You do not need annoying hub rings to get a vibration-free ride. It makes the install clean and professional.

I noticed the fender gap stays exactly where Kia intended. Since the owner kept the stock suspension, the tires fill the wells without looking stretched. You get a tidy look without sacrificing your spine on potholes.

The spoke design on the Valkyrie has a nice curve to it. It creates the illusion of a deeper barrel despite the conservative 7.5-inch width. It adds a layer of depth that the stock wheels totally lack.

Watch out for heavy cornering loads if you run meaty tires. The 40 offset is safe, but wide rubber could tickle the plastic liners. I saw no evidence of rubbing on this car, though.

This setup nails the balance between form and function. It honors the factory geometry while giving the car a sharper, more aggressive stance. It is a textbook example of smart wheel choice.

What We Recommend for Kia Optima S 2018 Owners

If you own an Optima S, stick to a square setup. Staggered widths will ruin your handling balance and mess with your traction control. A 7.5 or 8-inch width keeps everything predictable.

Aim for an offset between 35 and 42 for that flush look. Anything lower than 35 will poke past the fender and look like a mistake. Stay in this range to keep your alignment specs clean.

Avoid the temptation to over-tire the car. A 225/50R17 tire gives you plenty of grip without rubbing issues. It keeps the speedo accurate and preserves your fuel economy.

Do not waste cash on spacers if you pick the right offset. Spacers just add stress to your wheel studs and introduce potential wobbles. Get the offset right from the jump instead.

Many guys make the mistake of going too big on the diameter. Stick to 17 or 18 inches to keep enough sidewall for our rough roads. You want to avoid bent rims after one bad hit.

Style and Build Analysis

The Black Machined finish on these Valkyries pops against the factory paint. That high-contrast look draws your eye straight to the center of the wheel. It makes the whole car look more expensive than it is.

I love how the machined faces catch the sun when the car is rolling. It breaks up the dark void of the wheel wells. The design feels technical and precise without being too loud.

This build proves that you do not need a widebody kit to have presence. It is all about clean lines and proper proportions. The Optima has a sleek body, and these wheels complement that flow.

Compared to other builds I see, this one shows restraint. So many people ruin their cars with cheap, gaudy wheels that do not fit. This owner chose quality that speaks for itself.

The stance is aggressive but functional for real-world driving. You can park it at a show or drive it to the office without looking like a clown. It is a classy upgrade that respects the original design language.

Why We Love This Build

This Optima hits different because it looks like a factory prototype. The Black Machined RTX Valkyries catch the light and make the car look planted on the pavement. I love how the design mimics the sharp lines of the bodywork. It is subtle, clean, and perfectly executed for a daily driver.

Seeing this car parked under the lot lights made me stop and stare. The contrast is sharp, the fitment is honest, and the vibe is pure automotive joy. You do not need a massive budget to turn heads if you have good taste. This build is a masterclass in smart modifications.

Stop overthinking your wheel choice and just go for this setup. Your Optima will thank you for it.

Understanding wheel sizing: diameter, width, offset and backspacing all affect fitment on your Kia Optima S.

We talk to Kia Optima S owners every day. These are the questions we hear most before they pull the trigger on new wheels.

Will 17×7.5 / 17×7.5-inch wheels fit my Kia Optima S? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.

Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.

Can I daily-drive this setup? Absolutely. Thousands of Kia Optima S owners run 17×7.5 / 17×7.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
