Wheel sizes are getting bigger and bigger, with seemingly every new automobile generation offering wheels with larger diameters than the previous generation. That includes GM’s full-size SUVs, which offer 24-inch wheels options in conjunction with the latest 2025-model-year refresh. Of course, that shouldn’t come as a surprise, as GM’s chief designer hinted way back in 2019 that 24-inch wheels and even 26-inch wheels were coming. Which begs the question – where are the 26-inch rollers? Well, as it turns out, the bigger wheel sizes are presenting GM with something of a challenge, in particular when it comes to fitting them with tires.
In a recent interview, GM Authority Executive Editor Alex Luft spoke with the program engineering manager for the 2025 Chevy Tahoe and 2025 Chevy Suburban, Steve Kersh. We asked Kersh if the GM team has tried to put wheels larger than 24 inches in diameter on the refreshed SUVs.
“The limitation is not so much the size of the wheel but the size of the tire,” Kersh told GM Authority. “If you have less tire, you can imagine the issues that would occur. We’re not doing that.”
Although Kersh did not specify the challenges associated with larger tires, there are a few obvious disadvantages. Among these are a stiffer, rougher ride due to a low-profile sidewall, as well as an increased risk of tire failure or blowouts, especially on rough roads. There’s also the issue of tire production. In fact, in order to bring the new 24-inch alloy options to market with the launch of the refreshed 2025 Chevy Tahoe and 2025 Chevy Suburban, GM partnered with Bridgestone to create a new tire with a new tire size specifically for the application, namely the Bridgestone Alenza A/S 02, sized at 235/40R24.
“We still want to balance the vehicle – beautiful proportions and looks, fantastic ride handling. That’s our goal,” Kersh told GM Authority. “People do all kinds of crazy stuff. Yeah, I love it, but you know, we’re not going to try.”
