CT for 2007 Vstar 1100 Classic(cast rims)

Post  mayrel on Fri Dec 16, 2016 4:13 pm

I've read where the biggest problem is mounting a CT to a motorcycle rim. Apparently there is a big difference in the inside of the rim where the bead of the tire seats. But I've also read where certain tires fit fine and will seat easily. I'm currently running a 170/80B15 Bridgestone. My interest in running a CT is my bike is a sidecar rig. The driver tire wears the fastest particularly when hauling a sidecar around that weighs over 200 pounds.
I received one input depicting a diagram of the inside of the motorcycle rim compared to a car rim. There is a small difference in the outside diameter of the rim and a bead-stop(small bump in the rim where the tire seats). This fellow explained you can remove the rim and take it to a machinist and have the outer rim edge milled down just a little(exact measurements I have on his input)and also mill down the bead-bump. He recommended purchasing a used rim to experiment with. These go for about $200 which is a lot of cash to experiment with.
I also realize there is a lot of controversy about going to a CT on a bike; safety and insurance issues. But if there is proof from owners like yourselves that a CT will work on my bike, and you can share with me the brand and exact size tire you used, I'm willing to give this a try when I need to replace my rear tire. I just had new tires mounted less than 200 miles ago.
Early thanks for any help, Mayrel.

First,
There is NO insurance issues running a c/t on a bike in the states. In all my years running a c/t and looking on the net I have yet to find a person being denied a claim because of his tire of choice. Hell if you wanted to you could run a dirt bike knoddy tire as long as its DOT approved.

I also have never seen anyone mill their rim to get a c/t to "fit". 15" rims are the easiest to mount, when you get to the 17" and 18" rims then you can have problems seating the tire(some 16" rims too).

Looks like $57 with free shipping. Don't over think this, its not that complicated.

Thanks Rod for your input. I found Yokohama 185/65 15 is one of the tires which will fit a 15" rim on my bike(cast rims on 07' Vstar 1100 Classic). I need to find out what the numbers mean in terms of height and width in comparison to the recommended tire size for this bike. I'm running a 170/80 15 at present. When I need to replace the rear tire, I'll try the CT. Thanks, John

OK read this
http://www.americastire.com/en/learn/reading-tire-sidewall

Now what I'd do is take a tape measure and see how tall your bike tire is then look for a car tire around the same size. I would also go a little taller (1 1/2" or less taller) A 165 c/t will put down more rubber than your 170 bike tire so you don't need to go real wide, 185 is as much as I'd go.
When you take off the rear tire measure how wide your rim is and post it. You don't want to go with a wider tire if the rim is not wide enough.

I just took a look and it looks like the '07 has a 4.5" rim, you could go up to a 195 wide tire if it is a 4.5" wide rim.

Yes, 15" rim but I think its 4 1/2" wide so it can take a 195mm wide tire.

Sorry Rod, I misread your comment; must be an age thing! I will see what I can find on line; sure wish some one had already tried this on a similar bike/rim like mine. John

Thanks Rod. I had seen this be didn't realize it was a conversion table for CT's. I just had new tires installed a couple months ago. When the rear tire needs replacing, I'll install a CT. Based on what I've read the 15" motorcycle rims are suppose to be the easiest to fit a 15" CT. I've also read where the 165/15 CT which is used on the older VW rims has been used. I believe it's not as wide as the 195/15. Considering I'm using this as a sidecar rig, wider might be better, as long as it doesn't rub anything. Another issue I need to address is the rear spring on the bike. I've found a progressive spring which will fit. The original shock should be fine, plus the difference in replacing the spring versus a shock and spring is substantial(installed about $180 or spring, $550 for shock/spring). The progressive spring is basically the same as stock but gets stiffer quicker. Cruiser suspension is designed to be soft and compliant, adding a sidecar you need a stiff suspension. Thanks again for all your help; I'll keep you posted. John
