Does anyone have any experience with TPMS? I am aware there are many after market systems available, but I am looking for one that fits neatly, not to obtrusive, and works reliably. The Direct method of monitoring is probably the easiest to install. Perhaps someone can remember a previous thread for this. I read somewhere in one of the overseas markets manuals that they are fitted standard. Alternatively is there another strategy to mitigate against being stranded with a flat tyre?
Thanks,
Barry

This may not be much help but if you're looking for something that'll prevent you from being stranded (I assume no spare being carried) then a TPMS probably isn't going to do much good. If you get a slow leak and aren't one to check your pressures regularly then maybe but the only flat I've had in 30 years of driving was a sudden deflation. By the time TPMS would've alarmed I was already well aware of the issue.

I have a factory system in one of my cars so can't recommend anything aftermarket but I'd suggest checking 4WD/Offroad forums as tyre pressure is a common subject and I know several offroad brands offer aftermarket systems, I've just never looked into any of them.

Whatever you do. Don't get aTPMS system that has the sender IN the wheel. My 911 Turbo had the factory in wheel system but the sender batteries failed after 5 years but the tyres were still good. My option was to ignore the dash light or strip the good tyres. New senders cost me $2 large. OUCH

Just bend over and check occasionally with a $20 digital tyre pressure gauge. Keep It simple.

Thanks guys, it looks like the technology is not quite there yet. It just terrifies me going anywhere without a spare. I understand that simply knowing the tyre is de-flating does not solve the problem, but it might just save the tyre from destruction, and maybe a roadside disaster - Murphys Law. We will just need to rely on the powers of positive thought.

Thanks again

As you have an NC3, you might already be all over this, but we've no way of knowing, get an RX8 space saver &/or a can of goop - at least you won't be stranded.

My other car (a vw) uses the abs system for the TPMS indirectly which means quite a big drop before it triggers.

I have been considering getting an aftermarket set for the mx5 which screw onto the tyre valves and connect to the display by Bluetooth. I have an Android head unit and could use these with an app but some of them come with their own little display unit. $100 on Ali express.

I agree I wouldn't go with an internal sensor even though they are more accurate.
