To all who poo poo the C/T on a motorcycle. I took an early morning breakfast ride to meet up with a few of the gang. Bike felt good leaving the house, short 40 mile ride to the meet up.

Leaving the Park the bike felt a little squirrelly at low speed but nothing major. Had Breakfast and then we split up and I headed home before the Heat.

Hit the Suncoast PKWY and traffic moves at a minimum of 85mph on that road. I was doing my share of keeping up and or passing, and everything felt just fine. Got to the house and I gave the tire a check and found 12psi in the tire.

Bike never felt loose passing and changing lanes at speed. No doubt that a Bike tire would have broken the bead and or had a total failure at that speed. I am running a Yokohama Envigor, and it actually performed like a Run Flat. I am sold on this tire and C/T in general on these Big Ass Bikes. my 2 cents.

I run that runflat tire on my GL1800 Goldwing and will put one on my Interstate after I run this taxis tire out.  I really like the Yokohama Envigor runflat.  Harder rubber but it saved us once when we rode several miles with no air in it to get out of the mountains 2 up pulling a trailer.  I've always ran a tire pressure measuring system when running a runflat.  Keeps me from having to check every morning but also tells me instantly if air is coming out.

I'm all in on car tires too Nick. cooldude

But how can you not notice 12psi??  (I suppose at high speed, the high revs of the tire may created a lot of centrifugal force keeping it up.  But slow, that thing should have been very squirelly.

Hole, leak, or not checked since Christmas?   Grin

Low air at speed will keep the tire feeling pretty good.

A few years ago I had to run up and over Fort Mtn on I 40 east of Asheville.

I had picked up lotsa small glass pieces on the BRP. Filled the holes I could.

Stayed overnight in Lenoir NC and had to get to M&R Cycles in Hendersonville.

I had a pocket full of quarters and stopped at avery air machine i could find.

BUT once at I 40 that's the only direct route.

I put 55psi in just before I got on I 40

It felt pretty good going up and over the mountain so I continued to Tunnel Rd

At the first air machine I had 10 psi and the bike was wagging it's head at slow speed.

My riding angel was close to me that day.  angel

When I was putting my TPMS caps on my MC wheels, the rear tire came up as 15 psi. I had ridden it that day, and didn't notice a thing (I had visual quick check caps on the valves at the time, but as you see, they don't work), and probably for the last 300 miles.

I check psi pretty regular Jess, I think the tire probably had 20 / 25 psi when I headed home. By the time I got home and checked it it was at 12 psi. So I guess I lost air on the way home, pulling tire anyway for rear service, will check then, dont see anything in it?

Yeah, (I think) I picked up a nail dead center in Roanoke.  But the tire still had the pressure in it I left home with (40), and I couldn't make bubbles, so I rode home on it, and lost no air on the way home.

I had it plugged with a single string plug (tire nearly new).  I seem to be losing about a half or whole pound a week (and riding on it), and there are still no bubbles, so I don't know if I actually have a tiny leak, or if this is just the usual pressure loss from sitting in a hot shed, and day and night temp swings. Pretty consistent with very gradual loss that has always occurred before the nail.

I always check my pressures pretty consistently, but now I do it every time the bike comes out of the shed.

One trick to look for leaks... stick in 55 lbs of air then do the warm soapy water bubble search (tread AND rim).  Just remember to let it back out.

I have been doing a lot of reading about going D/S. i plan on doing it when i need a new rear tire.
i am lucky enough that my local motorcycle shop is D/S friendly and will install it for me.

I always tip these guys.  Sometimes it's not easy to find places that will do it for you.

only had about 500 miles on my car tire. it saved me from going down.  riding state forest rds early one morning. 30mph slight curve with a wooden slat bridge in the middle of the curve. front tire hits it and immediately bike starts to low side, car tire hits the wood and immediately cycle stands back up and slide stops and I'm in control. I have zero doubt that a rear motorcycle tire would have continued with the slide and I would have went down. nothing but trees and lower ground and the stream is where I would have ended up. Thank God for the car tire rescue!!!

I have been Darkside for quite a few years, just wanted to put this out there for all the Nay Sayers. I have had to ride thru downpours where a car tire not only shines but Braking is also much better with a big foot print.

There's a lot more Pro's than Con's running Darkside, once u get use to it, U will never go back. Oh and the 30K miles between tires is a plus as well. Did the Dragon scraping floorboards many times, to Going over the Great Divide on Car Tires, I am sold  cooldude
