First time I am saying " this is a must have" for your bike or your whole stable.

As an added note: Years ago I was informed that 75% of the tire wear was in the first 25% of tread depth. Now this was for car tires, but going on Puc's post, it might seem to be true for MC tires as well. Just something to keep in mind.

Makes sense really. When the tire is new, there is lots of flex in the tread available to deal with the road surface, but as the tread wears the flex diminishes and so the rubber will start to scrape the road surface causing heightened wear.

Every time this thread popped up I would think "I should order that".... Ok, I surrender, just ordered from Amazon. I decided that it is too big a safety issue to ignore any longer.

 

Good move, you won't regret it. A word of advice...follow the installation instructions exactly. They can be a little touchy to install and connect the first time. But work well..

Ron. No.

 

The tire manufacture takes heat into account. If you set your cold tire pressure to the max on the sidewall or less...

Ok, I’m a bit confused here. It’s been my understanding from the “experts” that air pressure should be set at the recommended setting of the vehicle manufacturer (usually the sticker on the door of the vehicle or the sticker under the lid of the RSV trunk in our case), not the tire manufacturer. In fact I believe that has even been recommended on this forum some time ago. Is it relative to what type of riding you do, ie @cowpuc riding across the heat of the desert at 100 mph two-up loaded to the gills vs touring the backroads on a Sunday afternoon at 60 mph? Not trying to hijack the thread but some thoughts on this would be appreciated.

I think this in response to one poster commenting that he was surprised at the pressure increase in the rear tire after riding. This is just an assurance that as long as you set the pressure cold at OR BELOW the tire Mfg. Max Pressure spec. you are safe as they account for heat expasnion when designing the tire.

A good father will never abandoned one of his kids when summons and I am not about to do that now Son-shine :grandpa:even though I know I am going to step in it :big-grin-emoticon::witch_brew::stickpoke::witch_brew::big-grin-emoticon:...

You know your old Dad,,, you want the long version or the short version??? I know you would pick the long version :thumbsup:..

Many years ago I was sitting in a 4th year Business Law lecture in College.. The Prof began his lecture by reading a real life story about a man and his neighbor who had received extreme hand injuries from a lawn mower they were using to trim the hedges between properties.. Apparently this intelligent men did not know of the dangers associated with holding a lawn mower above the hedges in their hands and what would happen if their fingers got inside of the blade housing/deck.. The courts decided in their favor because no warning stickers were found on the deck stating DO NOT USE FOR HEDGE TRIMMING..

Many people will say,,, well Puc,, what has that got to do with tire air pressures,,, but I am sure you already know where this is going cause your smart like your old man :missingtooth:..

IMHO,, those factory numbers found on all street legal vehicles are put there to protect the manufactures and their dealerships as well as service centers from lawsuits that would result if a mechanic tried to determine the best PSI for any given vehicle.. I worked in a couple of auto service centers thru the years and was ALWAYS under the corporate rule to follow factory data to the tee,, under NO circumstances, as a Licensed Mechanic working for a company was I allowed to fudge the numbers,, whether it be in a tune up, front end alignment and yes,, even tire pressures and that was ALL,, 100% insurance based to protect the company. Outside of that,, with my own stuff and IMHO - any and all of those numbers are a guide at best for the savvy owner who wants to readjust his tire pressures to any given situation he/she may find himself in.. Personally,, I am not totally convinced that those numbers are not also fudged a little to increase tire wear to sell tires while at the same time still remain safe in the process too BUT,, you know me,, I am Mr. Conspiracy Man so there is that:witch_brew:..

 

Concerning the motorcycle tire psi concerns you bring up.. This is a can of worms that hours and hours of writing has been done about... One thing I would like to toss into your thinking Son cause I love you.. Your old Dad has seen many many issues come up concerning accidents caused by and people hurt by improperly inflated tires.. Guess what one thing that 99.9999% of the time pops up when ever I have seen this happen on street bikes??? If you guessed UNDER INFLATED TIRES you would have guessed right.. Over inflation,, on car/truck/bike/trailer and any other street application normally results in premature wear on the tire but seldom results in an accident.. Matter of fact,,, and speaking strickly of NON RACE/TRACK vehicles,, I have never heard of over inflation causing an accident except for the lame brain who cant see the cords sticking out of the tire and it blows.. That said,, I prefer to run at top recommended by the tire manufactures PSI or close to it at all times.. Yes,,, the tire may seem hard if riding one up with nothing in the bags BUT,, you know your Mom,, at any given moment we could be headed out cross country and end up filling the bags with all kinds of heavy stuff!! I like being always ready for adventure..

I will also add this though,, you are 100% on the "is it relavent to" question.. ABSOLUTELY! Dropping the PSI down to 25 pounds when off roading Tweaks is a MAJOR advantage!! Especially in loose stuff..

So,, all that said,, what do I suggest for finding your best PSI,, all around number... Because bike tires are made to run on a radius and not on a flat tread contact with the road I suggest that the next time you swap on some new tires,, inflate them to factory spec,,, now load up your bike and take a ride on it with it fully loaded like you were heading to Michigan to buy me an ice cream cone.. Go a couple miles,, get off and check the ride pattern on the new tires.. Is the contact area in the center more than a couple inches?? It shouldnt be... Your best handling is when you are able to ride the radius in the corners,, this increases the flickability and handling of your bike majorly.. Adjust air pressure allllll the way to top spec on sidewall if you need to to obtain proper contact patch.. Does that make sense?? Once you find the air pressure that accomplishes this task,, LIVE BY IT!! And live by it unless you switch brands of tires... Do this with both front and rear tires... Try it and see what ya think and then come back and let me know if you think I am nuts :crackup::beer:

There,, now I will let one of these other lop eared varmints :Im not listening toyour ear off!!

Dad

Does anybody remember the Ford SUV that was rolling over all the time? IIRC, that was found to be due the reccommended tire pressure from Ford being way too low. Any kind of sudden latteral control change at medium+ velocity resulted in the tires peeling off the rims and the truck rolling. Huge lawsuit over that one!

Ok, let's look at it from this perspective: I work for a manufacturer, although in an unrelated industry. Nobody knows a product and it's limitations better than the company who designed and manufactured it. The vehicle manufacturers do not design or manufacture tires. Tire manufacturers design and manufacture tires. Vehicle manufacturers buy tires from tire manufacturers just like we do. The recommended air pressure as per the vehicle manufacturer should match that of the tire manufacturer of the tire selected by the vehicle manufacturer to be the OEM tire on that vehicle. When the tire installed is not the OEM tire there may be a difference between the vehicle and tire manufacturer recommendations. I will go with the tire manufacturer recommendations every time.

Came in this morning and I have them installed. Only issue I had was one battery was dead and the other nearly so. But, they packaged 2 spare batteries in the box so it was just a minor annoyance.

I am in touch with engineering at fobo. They would like to escalate the battery issue to their quality team to find out how you got dead batteries and make sure it doesn’t happen to anyone else.

can you PM me the serial number(s) on the box?
