Which is it?????** A: I wondered the same, it seems to be thicker than a standard tube by a fair amount. It is a good quality tube, especially for the price. **Q: Will this fit a mh90-21 Avon cobra chrome tire ?** A: Yes it will it will fit any 21inch. I have the Dunlop harley tire and it fits fine. **Q: Where do you put the two nuts?** A: One nut goes at the base of the valve stem inside the wheel, the other nut should NEVER be used against the rim on the outside. It should be up against the valve stem cap. **Q: Will this tube work for 90 / 90 - 21 ?** A: Yes, 2.75 / 3.00 / 21 is the same as 90/90-21 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great IRC Quality *by on Reviewed in the United States 4 January 2021* Needed a replacement tube that could handle the gnarly rocks and roots I ride over. Tube is heavy duty and very thick. Stem feels like good quality and has good hardware for holding the stem in place. Installation was definitely more difficult than a thinner tube, but no where NEAR as hard as I had imagined. Was just a little careful and did my first solo tube change with one of these and no pinch flats.After installing I made sure to inflate the tube juuuust a bit so it expanded into the tire and that made all the difference. I also took my time in reinstalling the tire and was super careful with my spoons.Definitely recommend. ### ⭐⭐⭐⭐⭐ Verry strong *by on Reviewed in Canada 13 November 2018* Heavy duty ### ⭐⭐⭐⭐⭐ Tough tube *by on Reviewed in the United States 2 August 2025* Good quality fast shipping, changed my first dirt bike tube with no experience with no pinches using this tube ## Frequently Bought Together - IRC Standard Motorcycle Tube 80/100-21 HEAVY DUTY - IRC Tube 110/100-18 Heavy Duty - IRC Rim Strips - 21"/-- --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/446724660-irc-heavy-duty-tube-2-75-3-00-21-tr](https://www.desertcart.sg/products/446724660-irc-heavy-duty-tube-2-75-3-00-21-tr) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-08*
