Never been interested in installing auto tires on my MC and familiar with all the arguments pro and con. But the idea came and stayed and over 20+ years has taken a firm hold.
I am looking into the idea but loath giving up good handling in exchange for longer tire life. That said run flat tires and less costs to changing tires is very attractive.
What I am asking is has anyone gone to the Darkside, then returned to MC tires? Other challenge is finding a shop to install it for you.

Here is a good article from Rider that addresses it from all sides including technically.

I've been considering it for several years now. Just can't get myself to pull the trigger, even though they are less expensive than MC tires. The idea intrigues me, but at least I know what I have with the MC tires.

That article was from 2012, even in just the six years of that being published there have been major changes in both bike and car tires. I loved my bike when I had one, one thing I never skimped out on was tires....I always choose handling over wear.

Do I wanna skimp out on tires and maybe get a push or slide in a corner that cost me a wreck?? Or spend the extra bucks on a tire that would actually grip?? I'll spend the extra coin and sleep easier..

NOW....I can see the alure of car tires on some of the bigger bikes that do a lot of straight highway cruising speeds. I do have a very good friend of mine, his father has a GL1800 and for one trip out to Montana he swapped over to I wanna say a firestone tire in the rear. He said it was fine in a straight line, but once he got into turns, it took a lot more force to get the bike to lean over, dropping some pressure helped but he still said the bike handled funky in the mountains, when he got back he swapped back over to a set of metzlers and has never looked back. I believe he is getting upwards of 18-20K out of a set, he's retired and him and the wife just rack the miles up on the wing.

I totally understand - *When you refresh the rider article it updates to May 2016 updated article for some reason. I am probably getting a new Dunlop Elite 4 put on but makes for interesting idea.

I ran 3 or 4 on my XCT. They handle fine with a few exceptions.
1. If you are coming to an intersection where the road profile is a W you will experience considerable low speed instability. That said, you do get use to it but you need to pay attention.
2. You will scrape in the twisties more, not less. This is because your contact point is moved away from center, thus you must lean further for the same turn.
3. When you run one out and then install an E3 or E4, you will be amazed at how great you bike handles.
4. They are better if you have an encounter with mud.

On paper, the E4 looks great. Except for that center groove on the front - it tracks. An E4 on the rear, for greater wear and a Cobra on the front intrigues me.
I side with Paulie - I will always defer to the safer way to ride. Light colored helmet, extra lights, ATGATT.

I've been on the Valk forum since the day it went online (1998?) There are guys who have run a CT (car tire) religiously since that time. Was on a GW forum before that. Same-same with the subject of CT. Some guys swear by them forever-after, while some have gone there (... dark side) and returned to a MC tire. Some have refused to even consider the option. I've entertained the thought, but for my measly 8 or 9k miles per season I haven't spent much time arguing with myself whether or not to take the plunge. From all that I've read over the years there is a learning curve that goes with the running of a CT, and the particular choice of tire to go with. If a person is a distance rider each year it might be worth considering the seasonal miles vs. cost aspect. A very debatable subject based on all that I've read over the years.

If you've never tried, you'll never know!

I have run quite a few car tires on my wing over the past 8 yrs














For my type of riding with the XCT, I ordered a run flat for the rear, along with a Avon Cobra for the front, which I will install shortly.

Have you tried the 160/60 rear tire up front on your CCT. I suspect once you try it you'll never go back to a 130/70.

Car tires are designed for....................wait for it..........................wait for it.....................cars.


Motorcycle tires are designed for......................wait for it.....................wait for it.....................motorcycles.


I not only ride long, high speed highway miles but I like 'interesting' roads as well where it has been noted above, car tires are not, at a minimum, the most efficient. But, perhaps most important, getting back home in one piece is of exceedingly high importance. With all of the other risks inherent to riding a motorcycle, I choose not to add to the list by putting a car tire on my scoot.

Just my 1c worth of a plug nickle.


As for going to the darkside and coming back from it. I know a guy who is a pretty skilled rider that eventually got sucked in to the car tire vortex (primarily do to the mileage/cost factor as he put on a lot of miles) and put one on his bagger. Before the tread reached half its life he pulled it off and went back to a motorcycle tire.

I've tried 'double dark' with quite a few different rear tires on the front and found that with the 4-5 different brands of rear tires, (they were all dual compound tires) they would start cupping early as the softer compound on the shoulders of the tires wore away far quicker than the centre portion of the tread (I run 40 - 41 PSI) ..... so, I now stick with a purpose built front tires.

Any front tire I've tried with a front rib in the tread design, I found tended to follow tar snakes and grated surfaces etc more than those with a complete cross the face tread pattern.
Big reason why I chose the Avon for up front!

I could say the same thing about sucking dick. Never done it, but I know it's not for me.

I have ridden darkside and double darkside... The bikes steered like a dumptruck. No thanx.

I know... it's all about choosing the right car tire and finding the sweet spot on air pressure... heard it all before.

There was a dude on the Delphi darksiders forum who said he would challenge ANYONE to keep up with him in the mountains. I posted "I'm your Huckleberry" and they BANNED ME.

A good rider can get on a stock Suzuki Marauder 800 and **** YOU UP on a tight mountain road. It's all about the monkey between the seat and the handlebars.

That's the great thing about our countries! ... everyone can choose to do as they please! :wink

In these parts, one does not want a tire that racks due to the many grated bridges. One such bridge over the Columbia River is almost a mile long. I find that Cobras run the straightest on it.

Unfortunately, there are forces at work in both our countries that are narrowing down those choices. Ironically, they are the ones who profess to be pro choice. Go figure!

Thanks for talking about the handling issues encountered. Almost no one speaks to that. Safety above all but handling/fun (why I ride) trumps longevity and cost.

Ya know how a tire that gets ridden a lot on straight roads will wear flat across the middle? Ya know how a tire that's worn like that has like an 'edge' to it? There's a certain lean angle it doesn't like... it's teetering on the edge... it either wants to lean less or lean more to get off that edge. It also exaggerates any ruts in the pavement and steers the bike around to the point where it fights you.

A car tire out back feels just like that.

Neutral and predictable handling and traction are far more important to me than cost. I go through 2 rears and 1 front every season. Rears are $120 and fronts are $98. I can afford to ride on high-speed-rated radials, so I do.

This old guys get to chuckling when a motorcyclist talks about economizing, especially if it is at the cost of safety. Hey guys, its not only a hobby (which never comes cheap) it's your life. It's not only the original cost, its the upkeep too, my friends.
