The tyres on all my other vehicles, trailers and my quad are all filled with OKO tyre sealant. This does't prevent things from entering the tyre but it dramatically reduces deflation. In all the years I have been driving with it in the tyres I haven't had a single puncture - but when swapping the tyres the fitters have found nails and screws in there etc. I haven't put it in the Antara as it's a Co car so not really mine to mess with. If I am late for a meeting well so be it. But if I used it to tow as well, I'd certainly consider puncture reduction to avoid the need for the space saver. Or in my case no saver. I am really not sure I'd want to pull a van with no spare at all. Has anyone ever used the goo and pump to get them away? I guess it's similar to the OKO that I put in in advance but nothing will stop a catastrophic failure.
At least the TPMS gives you advance warning of pressure loss
The space saver is OK to tow, according to VX. However, the tyre has limitations, ie 50mph max speed, so I (for piece of mind) have a full size spare.
On the subject of tyre sealant,it is only designed as a get you hope temp. repair. There was a clip on "The One Show" on the BBC alerting drivers to the danger. If a tyre wall is punctured,the tyre should be replaced,but some drivers with the OKO type sealant are not always aware of the damage and continue to drive in danger.
