Pondering the Impossible?

I put on a cheap, off brand, tire not long after reinstalling the pig pen.  After only 1200 miles it is bald and now, after not riding for 4 months, almost flat out in the garage.

So, I made the decision to look into going to the darkside, putting a car tire on a motorcycle.  Researching the topic shows a consensus that you can't put a car tire on a pre 2009 Harley FLHT.  Reason being there isn't a car tire that will fit the 3" rim and inside the frame.  

Never the one to take no for an answer I will attempt to do what they say can't be done.  There is the possibility I have to much free time on my hands, but who knows it might even work!


  1. Many years ago I used to drive a Geo Metro. If I'm not mistaken, I had a 3 inch tire on that car. I remember the guy at the shop laughing at how small the tires were and saying that they never see such tiny tires.

    I know that the Metros are out again, but made by Chevy I think. Anyway, they had tiny tires back in the day. I'm excited to see what you do with this!!

  2. What does Troubadour day - never let fear and common sense stand in your way........

    You never know if it will work until you try it.

  3. Sash; all the small cars I have checked have 15 x 5" rims and I need a 16" to fit petunia. I'm nowhere near ready to give up.

    Trobairitz; What is this common sense thing you write of? That left when the love of a motorcycle set in.

  4. If you can find one, go for it!

    I used a car tire on the pusher wheel for my V-Strom DL1000 rig and it was a bit of a hassle finding the tire.

    Pro: longer wear

    Con: hell to find someone to change out tires. Luckily, I had a friend with the expertise and equipment. Shops won't touch it, in my experience.

  5. Charlie6; The pro added to the fact the bike no longer leans makes this sound to good to be true. The con is a good enough reason on its own to make me want to do it. Following the rules isn't my strong suit.

  6. Just use a BFH* to install

  7. B. D.; I tried the BFH. All I got was a bent rim and busted knuckles.

  8. Good luck in your search for a tire. I just passed 7000 miles on my pusher but it is a square profile tire designed for use on sidecar rigs. I hear that car tires last much longer than that especially with a heavy bike such as yours.

  9. Richard; Rim size is a big issue on the Harley and weight. There isn't a K Block tire that will fit, Heidenau makes the square cut tire, but the 16" one is to small for Petunia. Going to see a bike wheel expert tomorrow to see how big I can make my wheel. Just measuring I think I can use a 5" rim, but not sure if I can still use my hub. Finally having spokes may be an advantage. I have also found a site that claims a spoke wheel can be made to run tubeless tires. Then auto tires are to big. I'm not giving up until I prove to myself it is impossible.
