There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
FOBO question
- Thread starter Bigmo
- Start date
I run my F3L
at about 28 / 17 and usually inflate to 28.5 / 17.5 to account for a bit of deflation. I don't use FOBO but had bought it from Amazon and returned it. If you do a search on this site, you will find that people ride the fonts at 15 to 20. So you have to decide if you want a range for safety or comfort / preference. I check my tires manually every few days and set them to my exact preference 28.5/17.5. So in that context, if I used FOBO I would set the warning at +/- 1.

For the fronts set the low/high about 3 PSI each way... so for your 20 PSI set for 23 and 17.
The rear gets hot and pressure goes up a lot when riding. At 28 I had set for 32 high and the alarm went off on the freeway. The rear on a 80F day on the freeway went up to 35 PSI... I dropped my rear tire pressure to 26 and set my high to 34 PSI and low to 22 PSI for the rear.

Yes, exactly what Finless said....
Depending on ambient temp's, altitude, and time of day, your FOBO readings on the front tires will fluctuate as much a 4 PSI. The rear as much a 5+ PSI. Well, so much for those picky folks who try and keep their front tires inflated to within a 1/2 PSI of one an other. If you're headed south bound on the interstate in the afternoon your right front tire can show as much as 3 to 4 PSI higher than the left tire. That will require a lot of pit stops before one gets where one is going. The FOBO's are to help you detect an impending failure before it causes harm. The main goal here is to enjoy the ride and stay safe.

Yet another vote for Finless’ and 2dogs setting ranges, and for 2dogs statement above. I have never had an alarm go off at these settings. I do have the FOBO app live in front of me on my iPhone on the F3 and I have seen the psi show as high as 22.5 (starting at 20) on a long, hot day, so you could set the high temp to 24 (or a bit higher) depending on where you are riding.

You noticed....
I totally avoided using exact PSI figures for obvious reasons. Hint, hint, I didn't want to start another bru ha ha.

I have Doran Tire Monitoring system on my Spyder. We probably don't get as high of temperature as you get in California. I was on interstate 90 crossing So Dakota running 80 miles per hour at around 90 degrees and the most my rear tire went up was three pounds. It had 28 psi pressure and went to 31 psi. I was running 16 psi in my front tires and they went to 18 psi.

I was just stating what my tire gain was when riding in 90 degree temperature. I could careless what pressure people on here is running. I know what I am going to run in mind and careless what anyone else says. But what ever pressure you run my rear gains 3 pounds and front gain 2 pounds. That was in 90 degree temperature running 80 mile an hour for about 300 miles.A bru ha ha? On this site? Never happen, 2dogs:thumbup:

Not quite sure why you have quoted me when posting this response, Gerald? Am I missing something?

There are many outside conditions that can influence tire PSI. I live at 4000 ft. elevation and frequently go to 300 ft. elevation. Cool mornings at higher elevations to near sea level at 100+ degrees in the afternoon is likely what causes my PSI to vary a bit more than what you experience. If I just make a 3 mile run to the post office and back there's hardly any change at all. Maybe a pound and a half if even that much. I'm going to try the white caulk test at freeway speed and see what I get. I've done it at low speed but never at high speed.
