Real Time Tire Temps on Dash!

I haven't done this yet but i was looking into those IR surface temperature guns and wanted one. Finally got one on sale for $27 at Harbor Freight. Haven't used it on bike yet since my wheels are off and waiting for tires in the mail. Anyway, my idea is to get two small IR pyrometers with wire outs and mount them pointing at the tires and have a gauge that tells you real time front and rear tire temps.

- know when you get a flat cuz your tire is getting too hot. (if you dont already feel it)

-have more confidence and know that your tires are at proper temp especially in cold weather.

-be able to set proper inflation temp which gets you to proper temps recomended by manuf. example: in real life i doubt 36 - 42 is ideal psi for winter riding. Especially beneficial for people who ride into colder weather and who dont get on highway all the time since they may need slightly lower psi to get proper operating temp and full grip.

-don't have to stop to take a reading and when you stop the surface cools giving a different reading.

- some people may just put 36-42 and this may be costing them safety because in cold weather and in town they may never see even close to proper temps and this will cost evasive manover and braking traction even if you ride conservatively.

- you will learn when and how quickly tires warm up, especially after changing models or brands of tires.

Cons: cost, i have only found sensors which are $100 - $200 each sensor and that's without a gauge so far. actually closer to $200 each for desired temp range. That's why it's not in the making yet for me.

But i wanted to put this up here since it hasn't ocurred to me yet until recently this idea and i'm an engineer student. so i figured it would be beneficial to many which may wish to do this and see the benefit but haven't thought of it as i haven't ever heard of anyone having done this on a street bike. (I'm sure it's done on some race bikes for tire and suspension data).

A note about sensors: i've read that probe type sensors are more accurate since they get the inside tire temp instead of surface but i've also read from people who have both and used both simultaneously that they are both very consistent just that the surface reads consistently a few degrees lower than probe. I'm guessing that the degrees difference may be more in colder weather but after one person compares to probes for a couple different outside temps that difference will be known and can be taken into consideration if you want to be very accurate. It's probably not necessary.

Let me know what you guys/gals think and if you would consider putting this on yourself independently or if you would be interested if i tested and made a kit to be sold. with the prices i found so far it would total about $500 - $600 but i would think i can lower that with more research.

I personally would justify the cost since this is a safety feature and many people spend that on they're jacket and helmet combined. this will add a degree of separation between you and the ground and i beleive worth it. it also actually adds confidence since i would normally ride in the cold weather always kinda scared of my traction limit and this true fact based confidence would actually affect your level of enjoyment of the motorcycle.

couldn't you just take apart those temp guns you can get from the hardware stores and rig them up? they're not too expensive and they already have a display as well.
Yeah, i thought about that. I'd have to see how to power them and hook em up to a nicer gauge. they run on a 9volt as is. I'll take mine apart and try it. gotta buy more before the sale ends Dec 14th. BTW if anyone buys those from harbor freight you need the add coupon. maybe they have the ad in the store. these are $60 normally.
