snip Either would work but if you can find a wider (700 35~45) tube it would be better as it will not stretch as thinly to fill your wider tire. At any rate be sure to find the cause and correct the problem before fitting a new tube. Thanks for the response. At any rate be sure to find the cause and correct the problem before fitting a new tube. Flat tube when pumped up was leaking out of a patch : ) I did not see any damage to the tire inside or out where the patch occurred and the rim appeared smooth. The schrader/ presta fix I was referring to is here. Do you have any opinion? TIA. https://www.youtube.com/watch?v=76AQ8RFvCX4&t=127s |

You can put small things like Presta valves into big holes like Schrader rims but not the other way around without some metalwork. Unless you have some need or desire to change, replace with whichever valve was original. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

TIA. https://www.youtube.com/watch?v=76AQ8RFvCX4&t=127s Going with the concept that the simplest solution is usually the correct one, I would say to buy the type of tire made for the type of rim that you have. In this case a Schraeder valve. Why would you be limited to what is available at Wal-Mart? A local bike shop sounds like your best bet and in addition to finding you a tube, they should be able to answer your questions. I see no value in trying to get a presto tube to work in a rim made for a schraeder tube. Seems like just asking for trouble. -- duane |

I just use a Mavic Schrader to Presta Rim Valve Converter in each rim. They're just simple plastic inserts that reduce the diameter of the hole that takes the valve. -- Dennis Davis |

Installing a Presta stem in an oversized hole is certainly a bad idea. A suitable shoulder washer should provide adequate protection. Most of my rims are drilled for Schrader, while most of my tubes have Presta valves. Don't ask why I got myself into this situation. I initially used rubber grommets as adapters (because I had some). However those eventually crumbled or devulcanized from UV or chemical exposure. Another advantage to using an adapter is that I can stock only Presta style tubes, and they will fit both Presta and Schrader drilled rims. No need to stock tubes with both types of valves. Other adapter designs are available: https://www.google.com/search?q=schrader+to+presta+rim+adapter&tbm=isch I used a lathe to make a few that looked something like this: http://wheelsmfg.com/catalogsearch/result/?q=presta+stem+savers -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

When my kid was living at home stocking shraeders for his bike guaranteed he wouldn’t need to grab my tubes. Didn’t seem like an overly complex solution. -- duane |

On my road bike I bought a replacement rear wheel and it was drilled for Schaeder but the front wheel is Presta. I would prefer to only carry one tube. |

I did it, for the same reason that the O.P wants to change from Presta to Schraeder. I didn't have a pump to fit Schraeder valves. What I did was turn up a couple of shouldered washers to fit the larger Schraeder holes although it probably was over kill. A couple of years so far with no problems. -- Cheers, John B. |
