Description
Field work is hard on a tube. This one is built for it: butyl rubber, sized for farm service, and happy in either a bias or a radial casing. 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 18.4R30, 420/70R30. Fitted with a TR218A air/water metal stem, 1-27/32 in. long, so check that against your rim before you buy.
Features
- Keeps farm and tractor tires holding air, and runs in bias or radial casings alike.
- Fitted with a TR218A air/water metal stem, 1-27/32 in. long.
- Fits 18.4R30, 420/70R30.
- 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.
