Not to derail, but was looking at cigarette lighter volt meters and was like..woah, that's a photo inside an X3, perfect.. then noticed it was from you =D You think that's the best option to get?

Thanks for posting Lotus. Comprehensive and very useful as always. Any thoughts on what pressure to store summer tyres at?

Sorry if I am repeating, but I'm on the iPhone app and it's harder to search old threads. My dealer is offering a special on nitrogen in tires. I had never heard of this and wondering if people here had done it and what would be the benefits. It live in Wisconsin, so my winters are quite cold. Thanks for the help.

One caution. Set the tire pressure monitor to the expected running pressure and not at the garage pressure. It means first adjust the pressure to expected pressure in cold condition, set TPM and then inflate it to higher pressure.

What I do is "Lotus7 Math" each week as the average daytime temperature drops. Once I adjust the pressure (typically adding more air) I then set the TPMS. Should I actually be resetting TPMS later, once the air in the tires has acclimated to outside temperatures?

I'm planning to drive from 60 deg F to lake Tahoe where ambients are around 10 deg F, do you think I will get TPMS alarm as I had last set them when the temp here was 75deg?

Now my innovative senses are triggered and think that right way to generate TPMS alarm is : If Ts1, Ts2, Ts3 and Ts4 are the tire pressures when TPMS is set and t1, t2, t3 and t4 are the actual tire pressures sensed by TPMS, then Alarm shoul be generated if max{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} -min{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} > x amount of pressure. A warning for low tire pressures can be generated if max{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} > y amount of pressure. This simple mathematical formulation can take care of variations in tire pressures of all tires due to temperatures, altitudes, storms etc. Last edited by April1; 12-21-2011 at 09:31 AM.. |

Anyway for my Lake Tahoe trip this weekend, I am carrying a crude system of hand held tire pressure monitor and 12V air compressor incase needed to improve my driving pleasures. |
