Dark side, run flat or standard?

Post by Mountain rider » Sun Jul 01, 2018 9:28 pm



When doing the dark side, is there any advantage performance wise, to use a run flat over a standard tire? Obviously not having to worry about a flat is one, but is there a significant difference when cornering? I have a standard CT on the rear now, but with a long trip coming up, anything that helps cornering and comfort over the long haul is a plus. The wife will never let me return to a motorcycle tire, so what would be a good choice? Maybe something with a round shoulder.

I recently added a Yokohama 195/55RF-16 AVID Envigor ZPS run flat to my 2012. I like the Avid as it has symetrical edges making throwing the GW from side to side a little easier vs asymetrical edges. I often ride two up and pull a trailer and I like the added safety 'if' we get a flat I will be able to (hopefully) ride the bike to the shoulder fairly safely. The Avid Envigor is a popular tire with darkside Wingers.

I am still a DS wannabe but, in prep mode, have been doing a lot of reading. Have also gathered everything needed for my 2008 GL1800, except have not yet chosen a tire. Per what I have read, RF is one of the major benefits for going DS. The benefits, of course include safety, and being able to limp the bike up to 50 miles, without air, if necessary.

I have not yet chosen a CT, but have narrowed it down to what seems the three current most popular, and all are RFs (Yoko ZPS, Bridgestone DG, and Perelli Snow Control).

A major criteria for me is noise. I have read, mostly from car driver reviews of all season RFs, they tend to be noisy. I once had a Harley with a very noisy front tire, and suffered through till it wore out. But refuse to go down that road again.

Back to the OP, my vote is for a RF, but only a quiet one. LOL

From personal experience, having a Michelin RF ZP tire, the Alpin Primacy,

you definitely want to find a tire with a Rounded Profile.... the tire I have is much too flat and square on the bottom, and it takes effort to make it stay in a turn in the twisties.

doable, of course, and I am used to it, but I won't put another Alpin Primacy on the back of my bike.

it will be one of the other brands with the more rounded profiles.

As to RF or not, that depends on your "Safety Zone" preference.
I personally chose the RF ZP tire because I ride solo mostly and having a flat and setting in the heat without Air Condition is something I can't allow to happen. I have a medical condition that will cause me to have a heat stroke at 85*F if no cooling air is blowing past my face and body.

The ZP allows me to ride at least 50 miles to where the tire can be fixed or replaced.

Thanks, John
I think I'm going to give the P1 a try. My current tire works well, but gives me just the smallest wiggle when I lay over in a corner. I think I'm just running it up on the shoulder.

The little wiggle is probably caused by the sidewall, rather than running up on the side. A radial is built to flex in order to keep the footprint flat. If running a bias CT(harder to find) the sidewalls are generally stiffer than you'd find on most radials.

Someone told me the Pirelli P1 would turn my Wing from a Cadillac into a Maserati, he was right. The ride and cornering are amazing. I'm currently running about 34 PSI in it and can't see how it could possibly get any better. I used Ride-on for balancing, since its sealing properties are purely redundant with a run flat tire. If you're considering going to the Dark side, the Pirelli P1 would be a terrific first choice. We're going to take an extended ride this weekend, so we'll see how she does with two up. :mrgreen:
