Yonex Poly Tour Fire Tennis String

This string is designed for aggressive baseliners who hit with heavy topspin and need a high level of control. It is ideal for players who swing fast and want a crisp, responsive feel that helps them keep powerful shots inside the lines.

The silicone oil infusion reduces friction between the strings, allowing them to slide and snap back into position instantly upon impact. This rapid movement is what generates the intense spin and rotation on the ball.

Yes, as a monofilament polyester string, it is built for durability. It is designed to withstand the high-impact demands of powerful strokes, making it a reliable choice for players who break strings often.

This string comes in a 1.25 mm gauge, which is a standard thickness that balances durability with playability. It provides a good blend of spin potential and control without feeling too stiff or overly thick.

Like most monofilament polyester strings, Poly Tour Fire is relatively firm to provide maximum control. If you are sensitive to arm issues, you might consider using it in a hybrid setup with a softer multifilament string in the crosses.
