"SR" is an obsolete way of expressing the speed capability of a tire using a now largely discarded sizing standard. The size might read something like "P175/70SR13" under this old system. The same tire under the current sizing standard would read "P175/70R13 82S" In both cases the "R" means the tire is of radial construction, the "S" indicates the tire has a speed capability of 112mph.

To install a bike tire, first deflate the tire completely. Then, remove the wheel from the bike. Use tire levers to carefully remove the old tire from the wheel rim. Next, insert the new tire onto the rim, making sure the bead of the tire is seated properly. Inflate the tire to the recommended pressure and reattach the wheel to the bike. Check that the tire is centered and secure before riding.
The process for tire tube replacement involves removing the tire from the wheel, taking out the old tube, inserting a new tube, and reassembling the tire onto the wheel. To do this effectively, make sure to properly inflate the new tube before installation, use tire levers to remove the tire, and check for any sharp objects inside the tire that may have caused the puncture. Additionally, ensure the tube is properly aligned inside the tire before reassembling it onto the wheel.
To put on a new bike tire, first remove the old tire by releasing the air and unhooking it from the rim. Then, insert the new tire onto the rim, making sure it is aligned properly.
