I know one is tubeless and one is tubed but what are the benefits to this? How do I convert my mountain bike tires tires
Tubeless tires have a different compound to enable capturing the air. Changing from tubed to UST can be VERY expensive: If you have single wall rims I would forget it as double wall stuff is required. Here's how to do it: 1) Purchase UST rim strips (about $40 EACH), UST tires (about $50 EACH), and sealant; 2) Remove the old tire, tube, and rim strip; 3) Install the new rim strips making sure it seals; 4) Install the new tire and place the wheel on a truing stand; 5) Unseat a small section of tire and pour in the correct amount of sealant then reinstall the tire; 6) Fill the tire with a high pressure burst, using a luggage hold down strap to go around the tire until it seats. Note that it WILL leak and WILL spew sealant- the amount spewed will depend on how careful you are; 7) Once the tire seats, fill it to approximately 35 psi and rotate the wheel slowly for a few minutes until you can no longer percieve air leaking; 8) Let the wheel sit off the bike for 24 hours and check pressure again. If the pressure remained steady inflate to desired pressure. 9) Plan to do this each time you have to dismount the tire (sans the rim strip) and about 3 additional times per riding season. Yucko.
