Wireless Air Pressure Monitoring

[Ron]

<FONT face="Comic Sans MS">For those of you that love gadgets and those who don't have a pair of those finely calibrated buns, the ones that allow you to "feel" when your 35 series tires are a pound low on air, might I suggest a Smartire wireless air pressure monitoring system.

I purchased mine from Jon B @ Partsrack and installed it earlier in the week. Installation requires removing the tires (which I had to do anyway as I was upgrading to forged wheels) and strapping on the 1.48 ounce sensors. The sensors are color coded, so you know which tire is reporting.

The sensor reports air pressure (accurate to 1.5 psi) and internal tire temperature (accurate to 5.4 degrees). In addition, it will warn you via a red light and audible signal if a tire is above or below a preset limit (which you set) and above a preset temp.

I found every tire pressure reading exactly the same as or within a pound of my external gauge, so quoted accuracy seems correct. The sensors are rated to 200 mph, have a &gt; 5 year battery life (non-replaceable). Replacement senors list for about $50.00 each.

I mounted the LCD display just below the dimmer rheostat. Easy to read and use. Requires just a switched power and ground connection, easily had by piggybacking a fuse under the dash.

More details can be found at Tirerack's website, but I found Jon gave a better price and of course, valuable advise, (plus it dropships from Tirerack anyway).

<FONT face="Comic Sans MS">My pleasure Doug.

Of course, you provide the ultimate "gadget", one which I hope you'll share with me someday.... (when I can afford it!)</FONT f>

Seems to me that next step would be to find out the "tire failure temps"...and I imagine that these will be reported as tread temps...then correlats said tread temps with sensor readings of internal air temps. This would need to be done for the 3 types of stock Michelin's used on Vipers, and also Hoosiers, maybe Pirelli's...anyone have a guess ??? Luke at TireRack???

Is the signal transmitted wireless? I could see a need for this on trailers (like mine) with 6 tires. You can't see when a tire goes down and usually can't feel it because the other two on that side are compensating for it. If it's wireless, then that would come in handy for most of us towing big trailers.

<FONT face="Comic Sans MS">It is wireless and the LCD display can handle up to 20 tires. I would imagine that there is a transmit range limit, but I do not know what it is.

<FONT face="Comic Sans MS">I confess, I did send John the link after chatting with him this morning.

One can never learn too much about cutting edge technology.... and I agree, seems like a great company and product.</FONT f>

I also just installed this system. I'll post a pic of how I did the remote display later. I have to say I was skeptical but it does do what it says. I'm not sure necessarily how useful it is just yet but at t-hill last monday, it did a good job of alerting me of a high-deviation. It was real cold when we got started so when the track and tires heated up, my tire pressure was way too high. I was out on the track when the deviation alert came on and displayed the psi of just how high it was getting. This was handy - not earth-shattering, but handy.

As Paul said, this system on a trailer would be great and I'd highly recommend it for that type of setup. I also got it because I'd like to do the silver-state sometime and this system seems like great peace-of-mind for an event like that.
