When Should Tires Be Replaced?

The two key indicators that your Acura RDX needs new tires are time and mileage. With most drivers covering 10,000 to 15,000 miles per year, you’ll likely reach your tires’ mileage limit before their age becomes a concern.

However, once your RDX’s tires pass the five-year mark, replacement should be considered regardless of mileage. The sophisticated compound of rubber, kevlar, and specialized chemicals that protect your RDX’s tires against UV exposure, temperature fluctuations, and road hazards naturally degrades over time, reducing their effectiveness and potentially compromising your luxury sport sedan’s performance.

Acura RDX Tire FAQ

What tire sizes fit the Acura RDX?

Tire sizes vary by generation. The 2006–2012 RDX uses 235/55R18, 235/50R19, and 245/45R20. The 2013–2018 generation runs 235/60R18 through 255/45ZR20 depending on trim. The 2018–2027 RDX uses 235/55R19 and 255/45R20. Lionhart carries fitments across all three generations.

Which Lionhart tire is best for the Acura RDX?

The LH-Five is Lionhart's go-to performance option across nearly every RDX generation and fitment. For 18-inch setups on the 2013–2018 model, the Imara H/T and Lionclaw H/T offer a smoother, highway-oriented ride, while the LH-Ten, Ramani A/S, and LH-503 provide sportier handling for the 255/55R18 size.

Does Lionhart offer tires for Acura RDX owners with aftermarket wheels?

Yes. In addition to all OEM replacement sizes, Lionhart stocks niche and non-standard sizing options that accommodate a wide range of aftermarket and custom wheel fitments. Browse the full size catalog to find the right fit for your setup.

What's the difference in tire sizing between RDX generations?

The second-generation RDX (2013–2018) has the broadest range of factory sizes, spanning five different fitments across 18-, 19-, and 20-inch wheels. The current generation (2018–2027) simplifies this down to just two sizes, 235/55R19 and 255/45R20, across all trims.

How do I know which Lionhart model is right for my Acura RDX?

It depends on your priorities. If you want a comfortable, quiet highway ride, the Imara H/T is a strong fit for 18-inch wheels. If you're after sportier handling and cornering grip, especially on 19- and 20-inch setups, the LH-Five or LH-Ten will better suit your driving style.
