Darkside regrets???

12

Anyone mounted a car tire on their rig then regretted it? 

Let's hear from those who have actually gone dark side...  tell us your first hand experience please, not a friend of a friend's brother's cousin's hearsay.

 

 

 

I've run a car tire on the rear of my 1998 Valkyrie since 2016   I have no regrets for having done it,  though I've learned not all tires of the same size are in fact the same width.   Study the tire charts to find which car tire sizes are the same diameter as your stock motorcycle tire so you don't get too misled by your speedometer.  I believe my current tire is a P205 60R x 16" and by GPS speed is very close to what the speedometer reads.

darkside is not for everyone but I think you are going to be hard pressed to find people that installed a car tire and then regretted it. I know there are a few out there that just didn't like the way it handled and removed them but they are few and far between. I too have been running dark side for many years, even before I found my way to the offset world of sidecars. I had 2 rear MC tires fail on me, most likely from too much weight, running 2 up with camper in tow. so sure it was probably my fault, however I have NEVER had a car tire give up or even act like it was going to get me in a precarious or dangerous situation. I run them right down to the wear bars and then put another one on

I’ve a feeling that Jan is asking somewhat rhetorically and building a discussion. 😉

that said, with exactly 90 miles on mc rear tires and 4 miles on car tire rear, I am comfortable saying that I don’t see a point at all of keeping a mc rear tire on the back of the tug.  Three times the cost, ¼ the lifespan and nothing like the load rating of a car tire just doesn’t even make sense.

I know, “lurk more and post less”.  I will get my popcorn.  This should be better than an oil thread!

In addition to the benefits mentioned above, the additional rubber on the road with a car tire mounted on the pusher of Mrs. SwampFox's Burgman rig seems to help braking efficiency as well.

In Nova Scotia a car tire on the rear separated while cruising along about 50 -55 mph. We weaved and swerved a little, but kept it under control.  Of course it was a holiday weekend, nothing open in Antigonish for three days. Finally could order a new tire, then two days to get it.  Five days of feasting on small town fish & chips, hand dipped chocolate milkshakes...

Wow Jon

glad to hear you were able to get it stopped safely. That is probably only the second or third time I have heard of a CT failing 

Did that make you shy away from the CT. just curious what style and size tire was that

This is a REALLY handy link to a tire size calculator.  Plug in the old and new tire sizes and it will give you all sorts of useful information, including diameter differences, affect on speedometer , etc etc. I've used it often when looking at changes on bikes and cars.

On my first rig, bought used and well set-up by the previous owner, I had interchangeable car tires on the rear and sidecar. It was an adventure-style rig [2005 GS + DMC M72D] and both tires were Vredestein Snow+. Fantastic traction in all kinds of terrain, great tire mileage and handling. The front was a stock motorcycle tire; I converted it over to a car tire using one of Strokers centerline automotive wheels and also ran a 15" Snow+ on it albeit a different size than rear. Only down side was the the tire tracked highway truck ruts more than the motorcycle tire did.

On my current rig, I have no option but to run car tires, and I am happy with that. I just wish EML would build their rigs with same-size wheels/tires on all 3 corners.

That was the tire Slacker used to explore Mexico for several months before I bought his vstrom1000 rig. Most likely that tire was well past its expiration date though there was still plenty of tread on it as can be seen in the last photo. Yes there was weight on it but not exceeding its load carrying capacity. 

BBBaker now has that tug with a Canadian tire on it.

Am still using car tires on the rear of my rigs.  Have even used a space saver donut tire on the KLR expedition rig. Was the only car tire that would fit the Kawasaki rear wheel.
