175 R400 Classic Tires

There aren't many cars that utilize a 175HR400 tire. 165HR400 is a relatively common tire size for cars of the 50' and '60s that were taking advantage of the modern radial tire technology. There were a few special cars such as the Lancia Flaminia Coupe, Alfa Romeo 2600 SV and some of the Ferrari 250 GT models that did use this extra ordinary tire size.
