I suppose ignorance is no defence, and safety has no price, but I wonder how many people realize that TPMS have a limited lifespan..?

I didn't tick the box and have kinda regretted it since, as I accept that it's an excellent step forward in safety, probably up there with the inertia seat belt. But at $1000 here in SA, and given that I've made do without it up until now, I'm just going to have to continue with the old-world precautions as to tyre safety, and to be fair, tyres themselves have come a long way too.

So mixed feelings I suppose...But time to move on....
