There are two options for tying the rebar. Either plastic cable ties or wire. I use cable ties. The argument for cable ties is that they will not rust. For horizontal rebar and simple joins in vertical rebar, I find cable ties are quicker to use than wire.
The letter R in a tire size stands for Radial, which means the layers run radially across the tire. Wheel Diameter is the size of the wheel measured from one end to the other. It tells us the size of the wheel that the tire is intended to fit. A size P215/65 R15 tire is made for a wheel with a 15 diameter. Load Index indicates the maximum load that the tire can support when properly inflated.
The industry rule of thumb is that for every 1/2 change in rim width, the tire's section width will correspondingly change by approximately 2/10. For example: a tire in the P205/60R15 size is measured on a 6.0 wide wheel and this size tire has an approved rim width range from 5.5 to 7.5 wide. The tire has a section width of 8.23 (209mm) when mounted on a 6.0 wide wheel.
