Description
Trail riding punishes tubes in ways pavement never does. This one is butyl rubber built for ATV and UTV service, where sidewall flex and low pressure are the norm rather than the exception. Worth knowing before you order: the size printed on a tube is a starting point, not a hard limit. Butyl stretches, so one tube covers a spread of sizes. This one fits 18x8.50-8, 18x9.50-8, 21x12.00-8, 18.5x8.5-8, 18.5x9.5-8. Fitted with a TR4 straight rubber stem, so check that against your rim before you buy.
Features
- Keeps ATV and UTV tires holding air through low pressure trail running and hard sidewall flex.
- Fitted with a TR4 straight rubber stem.
- Fits 18x8.50-8, 18x9.50-8, 21x12.00-8, 18.5x8.5-8, 18.5x9.5-8.
- Butyl rubber holds pressure noticeably better than natural rubber, so it stays up between checks.
- Made to stretch, so a single tube covers several tire sizes and you stock fewer part numbers.
