The Corsa G's luxurious 320 TPI is a final element that sets it apart from other tires. TPI measures the number of threads per inch in a tire's casing, with higher counts equating to a lighter tire with a suppler ride. Whether it's due to the high TPI, the claimed benefits of graphene, or a combination of both, we can attest to the Corsa G's supple road feel and ability to smooth chattering chip seal surfaces. In the clincher version, each Corsa G Plus will add between 235g and 265g to your frame, depending on size, and the tires' classic, gum-wall aesthetic makes them an eye-catching addition to your frame.
