There are loads of different sealants available from thin latex (best for minimum effect on ride feel of lightweight road tyres) to ‘heavy duty/ enduro’ sealants, which include extra clogging agents.
This new valve and sealant syringe kit from Swiss company Milkit can potentially take a ton of pain out of installation. The valves have cunning pressure sealing bases so the tyre stays up even with the valve core removed for faster air input. You can also inject/remove sealant cleanly through the valve to avoid mess and waste. Just make sure you drop tyre pressure below 20psi and lock the feed pipe as you stick the sealant syringe in or you’ll get a face full.
Different rims often come with different valve shapes, but valves with rounded/cone ends (Milkit, Schwalbe, WTB, Stan’s and others) tend to work best with most wheels.
Helps the tyre slip evenly into place. Washing up liquid works too.
If frantic pumping isn’t your thing, or you end up with an awkward rim/tyre combination you’re struggling to pop into place, a compressor is the answer, such as an Airshot (£49.99) or similar will be a lot neater. Alternatively, just get a motorised compressor (£70-plus). Beware of garage forecourt airlines though as they often use much higher pressures/dump volumes than are safe for your rims and tyres.
Spoke or construction holes in rim beds need to be sealed with tape to make them tubeless. Make sure the tape is wide enough to cover the whole bed.
(7) PRESSURE GAUGE
Take the guess work out of setting up your tyres with an accurate pressure gauge. The Schwalbe Airmax Pro digital version here costs £11.99.
