Look at my rear tire! Crazy!

[BLUEKNIGHT911]

Why Mike I am surprised in you, not giving the tire of the month shout out!!!:2thumbs:

:roflblack: ....I think I did ... I said it was a " CRAPENDA " :gaah:.......Mike

 

[BLUEKNIGHT911]

Respectfully, I disagree. I think most of the time the engineers DO know best. Unfortunately, it's the bean counters who override the engineers and install cheaper (both cost and quality) parts.

:clap::clap::clap: ........you nailed it ......jmho .... Mike :thumbup:

 

[Southpaw58]

If that Kenda tire has 16,000 mi , ( with lots of interstate ) .... then you are the luckiest person in the World :2thumbs:.....Mike :thumbup:

In all seriousness, that is the stock tire that came on my Spyder. I purchased it new 2 years ago this month and all I have done is make sure the pressure was correct before my trips. And it does have 16,000 miles on it.

What air pressure did you go by??? 28 psi?
I ran mine at 24 psi for quite a while. Just upped it to 28 recently.

I was serious, I have been on this Forum since 2012..... and your tire is very unusual from all the other Kenda REAR tires I have seen. ..... Mike :thumbup:

Yes, 28 psi on the rear and 15 psi on the front tires. The fronts look just as good as the rear.

 

[carsong]

Yeah, my front tires look like new! I'm a real stickler about tire pressure, and check it constantly. I suppose all the time running the rear at 24 psi was bad for it. I don't even really ride that aggressively. Plus, living in Florida, all roads in my area are straight and flat.

 

[BajaRon]

That's how mine wore and the dealer told me it was because I had the tire pressure at 29 PSI it was over inflated and caused the premature wear in the middle. He told me if I had the tire at 26 PSI I would have gotten more milage out of it. I don't believe my issue was pressure related, the tires do not seem to wear well.

You could run 15 lbs in the rear tire and you'd still get this wear pattern. The dealer should (and probably does) know this. Some dealerships just can't tell the truth. It's some kind of genetic defect I think.

 

[BajaRon]

I must be doing something wrong lol. This is my rear tire at the current mileage of 16,000. I have run the recommended pressure since new and check it before most of my trips. I travel a lot for my job, and I ride my Spyder most of the time (read lots of interstate riding). I am aware that it needs to be changed, and will be doing so this winter.

That is simply incredible!

I totally disagree with you. I have seen too many things ill designed regardless of the beaners assessment that I often say, "Where do they find these idiots?" I think that if engineers were forced to use the $*%t they design for 10 hours a day for just a week, they would design better $*%t. I redesign nearly everything I own to make them easier or better suited to use. Case in point: the grill I bought. If they would have added just 1/8" of lip onto the hood, the grill would not suck rain into it's guts and die a sad early death. Cost difference? Nothing. Think reverse curve gutter guards. That's only one example.

Same here. I've got 11K on my OEM rear Kenda and it's not quite down to the wear bars yet. I run 28-29 psi, check it often, always ride solo and drive rather easy. Slightly more wear in the center than outside edges but a lot of mileage left in it for sure.

 

[spyderwing57]

I think the rear tire was overinflated. I agree 26 Lbs. would have prevented this wearing.

Yeah, but if they made it so it last twice as long, you wouldn't be back to buy another one near as soon.

Doesn't that just prove a number of comments I have seen about Kenda quality control. If you are very lucky you might get a good one, otherwise you are with the rest of us.

True. But the average customer tends to think that engineers have the last say. Which, of course, is far from the truth. This is where the 'Engineers know best' mindset comes from. Technically, it's true. Realistically, it doesn't always make it to the retail product.

I don't think tire wear is a function of quality control. There are only 2 plies in the tread area. This is simply not enough strength to keep the tire symmetrical at freeway speeds. I am not sure where this ballooning begins to be significant. But I would guess that if you put most of your miles on at or below 50 mph, you might get a better wear pattern. But if you do a fair amount of 50+ mph. And especially 70 mph or higher. You're going to get this typical center wear pattern no matter what pressure you run in the tires.

Here is a good way to check. On a nice, flat piece of concrete. Run the tire through a wet spot and then out onto the dry. You'll see what kind of contact patch you have at 0 mph. If you are over-inflated. It will show up right there.

The chart below assumes the tread belts are adequate to resist centrifugal force at any speed the tire is rated for. Which is not the case with the Kenda's.

Yep, I got 10k out of each of my first two. Put on a Kumho on this time hope to get 20k.

Owners manual recommends29 psi in the rear.

Well, you give the beaners too much credit. Case in point : you would agree that the Spyder is more likely to be owned by someone over fifty. The F3 (at least in '17) had acres of digital screen banked by an analog tack and analog speedo. Then they make the time and temp font (among others) in 10 point Helvetica which is impossible for the age bracket to see - too far away for bifocals and too small for regular lenses. Plus they waste acres of space on the rest of the display. Don't know if they have improved on it 'cuz I haven't seen the later versions. Complete engineer failure. How about the standard fridge? Freezer, which you rarely get into up top, & the rest of the fridge that you likely get into frequently on the bottom. Unless you're only 4 feet tall, you gotta bend over to see what you have in there and there is a good chance you'll bump your head on the freezer door!

Speaking of rear tire on the back of the 2020 RT, does anyone have any good suggestions for an easier way to check pressure on this tire? It is extremely hard to reach and check/fill with air when needed!
Thanks for any suggestions.
