Sunlite Schrader Valve Tube

Yes, this tube is specifically designed for 18-inch wheels with a tire width between 1.75 and 2.125 inches. Please check the sidewall of your current tire to confirm your size matches these specifications before purchasing.

This tube features a 4.3mm wall thickness, which is significantly thicker than a standard tube. While this adds some weight, the extra butyl rubber provides a robust barrier against thorns, glass, and debris, making it ideal for riders who prioritize flat protection over speed.

Yes, you can. Because this tube features a removable valve core, you can easily inject your preferred liquid sealant to provide an extra layer of defense against small punctures.

This tube comes with a 32mm Schrader valve. This is a standard length that works well with most 18-inch rims, but if you have deep-section rims, you may want to double-check that your current valve stem length is sufficient.

While the extra-thick butyl rubber significantly reduces the risk of punctures from thorns and road debris, no inner tube is completely flat-proof. This tube is designed to minimize downtime and roadside repairs, but you should still maintain proper tire pressure to avoid pinch flats.
