The "crown" in the road will normally cause the rear to go the the right when you spin it.
That is of course if you happen to be going the direction you are supposed to be going in that particular lane at that particular time.

The centrifugal force is what made the tire go to one side on acceleration. From the belt being on one side
There is only one company I know that has over 4 years of experience and testing running tires on a one wheel rear drive vehicle. Can you guess? And they haven’t put mixed tread design tires on their vehicle yet, front or rear.

I feel your commitment to this topic, Bigdog. I spent considerable time researching tires for the Grasshopper where I contacted BF Goodrich, General. Goodyear, and several other major tire companies and they all said that there would be no problem mounting an asymmetrical tire on a tricycle. I honestly do not understand why you are wasting all of this time with us when your expertise would best be served advising these tire manufacturers on how they all are passing on dangerously erroneous information and have obvious need to rethink who they are hiring in their design departments, for they seem not to understand how their tires actually perform? Please, Bigdog, you would be doing a great service to us all, including tire manufacturers themselves, if you would contact these tire companies before someone is critically injured, or, heaven forbid, possibly killed?
Thanks,
Bill

Have 2k miles on this baby and doing just fine! Was a little slick and had to get the “new” off at the beginning but happy now. Federal super steel 595

One additional comment - While I wrote I never experienced any handling problems, I seem to remember a tendency for the rear end to move towards one side if I accelerated hard enough to spin the tire. I can't say if I was just imagining it, or since I was spinning the wheel when I seemed to notice it if it might have been associated with high torque, or if it was actually attributable to the asymmetric tire. It never caused me any problems and I think I felt similar slippage when using the stock Kendas. My current Nitto 555 G2 315/35R17 tire seems to be wide enough that sometimes it feels like one side is slipping under hard acceleration, but others times it seems to be the opposite side.
I'm still working my 305 Kenda and it slides to the right when the tire starts to spin.

These tires were on my final list, primarily because Les Schwab is local, and will be curious how they continue to work for you in the future?

Another one that does not come in 305...

Kendas are crap - so by your logic we should all use crap just because the factory tires are crap?
As only one company - what about Morgan three wheelers - - been around much for over 50 years - what tire is used on the rear of it? - - - they clearly have the most experience with three wheelers - so by your logic we should all be using what morgans use
-
That’s the answer what kind of tire do they use?
-
I did a quick Google Image search and saw motorcycle ties on the rear of the older Morgans and what looked like regular car tires on the rear of newer models. Michelin seemed to show an asymmetric tire for the newer Morgans, but I didn't take to the time to make sure.

My next new tire concern would be sidewall stiffness....and rim protectors on the sidewalk of the tire....lots of torque on the sidewall of the rear tire...from bends and acceleration...don’t need no mushy sidewalls..

Based on internet comments posted to various performance car forums, the Nankang NS-20 reportedly has a soft sidewall compared to other HP tires. I had one on the rear of my Slingshot and at standard interstate speeds, the tire seemed a little wobbly just due to minor steering wheel movements. Oddly enough though, if I tried a high speed chicane-type lane change (rapidly shifting from right to left and back to the right lane) such as trying to avoid tire debris or other road hazards, I never noticed any problems with the rear end handling of my Slingshot.

even though I dont need tires for the sling yet this is good reading and info for me. as far as asy. or sym. traed pattern I cant physicaly see a problem there but then again I am one of the people who runs a car tire on the rear of their motorcycle (2 wheeled one) and you know what they say about that.

I never ran "dark side", but I'd think if an asymmetric tire might be a problem, it would be most apparent on a two-wheeler when leaning one way puts a different tread pattern on the road compared to leaning the other way. As little as the Slingshot leans, an aymmetric tire on the rear doesn't bother me. If the Nitto 555 G2 I have on my Slingshot doesn't last as long as I'd like for the money, I plan on installing a Nitto Motivo (asymmetric) in its place.

I’ve read some tire reviews about some of the different tires that we could use....from people that installed them on their car...some complained about the soft sidewalls..
When you run low profile tires...like we do....a soft sidewall is not in our best interest...I would worry about breaking the bead in a tight turn, going flat and losing control...
I have to run heavy sidewalls on my vans...that usually means two extra plies on the sides .. which helps with load capacity and reduces flex.
Not that we have to worry about heavy load but with one back tire it has to be somewhat of a concern...I’m also thinking about all the potholes I haven’t missed....a stiff sidewall could help prevent rim damage...I hit a hunk of 4x4 going 70 with the back wheel...I missed clearing it by a half inch....took a bite out of my sidewall and nicked the rim..I got lucky. Didn’t lose air or control...
I’m not sure what the Kenda sidewall is rated..
One more thing.....I know the split tread design is to help with water removal....what happens if one side of the contact surface gets more water under it than the other side? Making it lopsided....I know we’re only talking about a few thousandths of an inch but could that make the one rear wheel want to do funny things...by making half the tire want to hydroplane...or lose more contact than the other side? Now it’s not helping it’s defeating the purpose....not as big of a deal with two rear tires...

Have you tried contacting tire manufacturers and sharing your ideas with them?

If you believe Polaris are the experts in what tires should be on the Slingshot then you must run Kenda's. In the service manual it specifically states that OEM tires are the only ones they recomend
