Hi,
I have read all the TPMS related posts here. A lot of you think the external ones are unsafe, especially on rubber valve stems.
I have used external ones for 5 years on classic Lambrettas and Vespas with angled metal valve stems without any problems (up to 75mph). My 2024 Vespa GTS has got rubber valve stems. According to Bennetts this should be no problem, as long as you replace the valve stems with every tyre change. The only problem I see is that the space between the wheel spokes is narrow and the TPMS cap might touch the spoke at high speed. Has anybody used them successfully?
Another question: Someone said the Vespa speedo display is already enabled to show TPMS information. Is that correct? What TPMS are supported by Piaggio?
Cheers,
Semp
