I just came across a two-year-old review of the current Hybrid Touring in the June 23, 2023 Road & Track entitled "I Like the Honda Accord More Than Most Luxury Cars." Below is an excerpt from that article regarding ride and handling in these cars. It exactly reflects my feelings about my 2023 Hybrid Touring, and makes me satisfied that no changes such as 17" tires are needed. Here's the excerpt from the R&T review:
" . . . .The Accord feels more sophisticated than any mainstream sedan I’ve driven, and better sorted than plenty of luxury cars. The ride is on the firm side of graceful, but without the harsh rebound or bucking a modern German sports sedan and its stiff chassis provide. The new Accord is closer to an early-Aughts BMWs. The body moves in corners and over bumps, softening the harshest edges without ever feeling sloppy or floaty. Push it hard, and you find a relaxed, competent canyon carver, always predictable and extraordinarily friendly."
Exactly the way I feel about mine. No 17" tires needed, thank you.
