## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [Pit Bike Chassis Parts > Dirt Tires and Tubes](https://tboltusa.com/store/pit-bike-chassis-parts-dirt-tires-and-tubes-c-50_1029.md)

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## Description (the store's own text)

Featuring a front-tire redesign, Dunlop's Geomax MX53 tire features a taller profile to offer a larger contact patch for smoother handling, a higher lean angle and better maneuverability. 1mm front tire blocks have been redistributed giving riders better steering feel and more biting edges. Horseshoe block pattern reduces stiffness for greater rider compliance, and grabs dirt to provide better braking grip. Tie bars between knobs reduce flex, improving durability.

**Key Features:**

- Superior grip in a wider variety of terrain from new block-within-a-block Progressive Cornering Block Technology (PCBT).
- Block-in-a-block rear knob design offers more progressive cornering action and aids in slide control.
- Enhanced handling and improved knob durability via more flex, and less knob tearing through recess carcass design.
- Front knob design, construction and pattern are optimized to work in one direction, which provides advantages in feel and traction.
