Does anyone know where I could find information on the max wheel pressure? I am looking to upgrade to the Goodyear G614 and it says they are 110psi. My current tires are rated for 80psi.
The most accurate information will be provided by the wheel manufacturer. They are required to provide model & serial numbers on each wheel along with contact information.
Off the top of my head they are a Chinese tire but properly made to ISO standards. If you do a google search you should find a lot of comments about them. One advantage to going to a Sailun 17-1/2" tire is that the tire circumference is no greater than typical 16" tires. Again, google is your friend.
