does anyone run a TPMS system?

does anyone run a TPMS system similar to

RV AND RV TRAILER

these are internal as opposed to screw-on and measure temperature too..

That Valor system looks pretty cool. I wonder whether they sell it for one-off projects like ours? I had always assumed I'd have to brew my own with a TPMS receiver reference design from Atmel or Microchip and buy compatible transmitters on eBay or something. The Valor system looks spendy enough that I'd still hack my own instead of buying theirs..

ive thought about doing exactly that.. building one.. then I found there are quite a few online so I may not roll my own.. esp since some of them have RS232 ports on them so I can keep Techie-Geek theme going in my Bus...

I found one PressurePro system on amazon for 4 wheels .. it is a little less eye candy for the screen but goes for $350.. you need 2 more sensors at $50 each for 6 wheels.... the disadvantage to the Valor is that you have to have the tires dismounted and remounted to install it.. so that adds a lot of spendy.. whereas something like PressurePro is screw on sensors right on your valve stem so they are less pricey..

the upscale version of the pressurepro is spendy..(pressurepro pulse).. it is $700 complete for 6 tires.. its more commercial.. does data logging and has RS232 port..

they do sell an embedded board for DIY projects..

i use a bat. my friend had a system like that and had nothing but problems with it. they would not work at all or give false readings/ alarms. the sensers he put on the tow vehicle require you to put about a pound of counter weight on to balance out the tire. he took them off a few months after he installed them.

how do you get accurate readings with a bat? or are Even and equal tire pressures not as critical on a Bus as they are on a car or esp a 4x4...

I always used to check them all the time manually.. had extenders on my Tandems. . but was looking for a more modern way..

which system did you have that worked badly?

most of the things im looking at now are .5 oz or less sensors so i can simply counterweight it opposite assuming my tires are balanced from the beginning..

you mean your not using the dynamic golf ball counter weight system?

trust between stops has been the otr truckers mantra for over 100 years. tire sound can tell a 7 pound difference to the discerning ear. just by hitting with a bat. that and the thermal gun allows instant readings for things like differentials and hubs and exhaust at the cylinder head, serpentine idler pulleys electrical boxes for the E after 444E or 466E, auto trans sump trailer hubs etc. all for less than 50 dolllars.

the thermal gun I get.. in fact I carry.. and I agree easy to use for many functions.... and very quick to do a walkaround at a stop and ht various components.. yes Ive used these in the Mechanical world for a long time.. and correct very Cheap..


I just dont understand how to tell that ive got 100 PSI in a tire by hitting it with a bat... I suppose I'll learn it if thats what everyone does though id rather have numbers.. maybe because im a computer and physics kida guy so I like to see numbers to things....

Get a club, small hammer, axe handle or even a tire iron and thump on your tires. It's almost guaranteed that you'll hear the difference in tone that a low pressure tire produces. This has been used for years by truckers. For heat, just put your hand on the tire, wheel, brake drum or differential.

Technology doesn't always cut it. Yes it's fun to play with but an investment into a bus deserves real world information even if it's not numbers.
