Yes, you can put skinny tires on a mountain bike. However, it is important to consider the purpose of your bike. If you plan to use your bike primarily for off-road trails and rugged terrain, narrow tires may not be the best choice as they do not offer as much traction or stability. If you plan to use your bike mainly for commuting or road riding, swapping out the tires for narrow ones can improve the bike’s speed and efficiency on paved surfaces.

To replace a mountain bike tire, first release the brakes and remove the wheel with a wrench. Use tire levers to pry the tire bead off the rim and remove the old tire. Check if the rim tape is intact and correctly positioned. Install the new tire onto the rim and make sure the bead is seated correctly. Inflate the tire to the recommended pressure and reattach the wheel, tightening the bolts to the appropriate torque. Finally, check brake clearance and adjust if necessary.

To dismantle mountain bike forks, first, remove the wheel, brake caliper, and brake hose. Then, use an Allen key to remove the top caps and loosen the bolts on the lower legs. Slide out the stanchions and remove any spacers or washers. Remove the old oil and seals before replacing with new ones and reassembling the fork. Finally, test your suspension to ensure proper function.

To jump a hardtail mountain bike, start by gaining speed and then focus on having a balanced body position with your weight centered over the bike. As you approach the jump, shift your weight slightly back to preload the suspension. As you reach the lip of the jump, explode upwards and forwards, using your arms and legs to push the bike up and off the jump. While in the air, keep your body position balanced and level. Upon landing, absorb the shock by bending your knees and elbows, and immediately regain control of your bike. Practice with smaller jumps before attempting larger ones.
