2026 GV70 2.5T AWD - Can I upgrade from the 19" Alloy Wheels?

[fmetz374]

Hoping to see if anyone else has done homework on the 2026 Genesis GV70 as it relates to upgrading the wheels? My 2.5T AWD comes with the 19" alloy wheels, and was interested to purchase and upgrade to the 21" factory OEM wheels that come on the 2.5T Sport Prestige Trim. I have checked with a couple dealer's parts departments, and they said this is not possible nor recommended as the suspension is tuned on mine for the 19" alloy wheels. Additionally they said even if I did swap out the wheels for the bigger 21" Sport Prestige wheels, I would be inviting all kind of trouble due to the increased wheel diameter causing calibration issues with the speedometer, ABS sensors, transmission, etc. Curious if anyone else has done any research on upgrading the wheels on a base 2.5T AWD to the bigger 21" diameter found on the Prestige Sport trim?

Total horse sh!t. You get tires to match diameter of stock. MANY people change their wheels without issue. I too kept my 19" for winter and purchased 21" aftermarket wheels, flow formed, light and custom milled offset for a flush to fender look and perfect match to our hub for summer. Lots of threads on this forum about wheels. I oversized my summer tires to slightly larger diameter 265/40/21 (stock 21" is 255/40/21) without issue. Good site to see difference in size and speed of tire sizes, google Tire Comparison.
