    Problems with balancing a tire

    My problem is simply it's taking 3oz of weight to balance my new rear tire.

    I bought a set of Shimkos and I mounted the rear today today. When I try to balance the tire, it take 3oz of weight at the valve stem. That's a lot of weight by my experience. The original tire only had 1 oz of weight in the same spot on the wheel.

    To be fair, I've been working on the wheel and may have taken off a light weight but not this much.

    The red circle is three inches off of the valve stem but since the weight is at the other side it shouldn't matter that much.

    I tried to rotate the tire on the rim but it wouldn't budge. My thought was to place the mark at the opposite side of the valve stem to help distribute the weight.

    Any comments would be very helpful.

    I have run into rear Shinko 712"s that take a lot of weight like yours. I have had some also that take little weight to balance. Must be the pitfalls of a $60 tire. When I balance a tire, I run the rim on my balancer first without the tire and find the heavy spot and mark it. Then when I mount the tire, I line up the light spot mark on the tire with the heavy spot on the rim and that way it will take the least weight. The valve stem isn't always the heaviest spot on the rim.

      In hindsight I should have done that. I hadn't replaced the bearings yet and wanted to mount the tire before I put the new bearings in. I will certainly do that on the front one.

        break the bead loose on both sides and spin the tire 180 degrees.

        BTW.....did you line the dot on the sidewall of the tire up with the valve stem? There should be a red or yellow dot.

          8oz. bottle of Ride-On with 4oz. in each tire balances, reduces 'cupping', extends wear a bit AND gives flat protection. Least has been my experience past 4yrs. on my two different bikes. Majority of bike shops offer that as an option and retail it.

            I would split the weight. Make it so you have three heavy sides instead of two and call it good. I learned how to balance car tires that way when I was a kid.

              Hi Rich,
              According to the sticker on my Shinko 712 tire:
              The Red spot is the LIGHTEST part of the tire.
              Try taking all the weights off and begin again.
              Good luck

                I'm having a lot of trouble spinning this tire.

                The red "dot" is near the valve stem (it moved on me). I'm going to try and reverse it to see if that lowers the weight difference.

                However, I still need to spin the tire. I broke the bead but it still won't spin, even when lubricated. It was a very tight tire to put on in the first place.

                  Shinko's are pretty soft sidewalled compared to most others. I'm suprised you can't turn it on the rim. Pull one side of the bead off and you can move it.

                  I have Shinko on the front of my bike I can't get right either. It hops right at 75......frustrating. I've tried everything.

                  The rear isn't usually really a noticeable issue.

                    Greg, you possibly have one of those egg shaped front Shinko's, I've had a few and I sent them right back, that hop is annoying.

                    Rich, you learn as you go, all good avice from everyone.

                      Did you break the tire away from the rim on both sides?

                        As a follow-up...

                        I was able to rotate the tire once I used soap and clamped the tire away from the rim. I placed the low side dot 180 degrees from the stem and it balanced with less than 2 oz. On the front tire, the dot was next to the stem and it balanced with less than 2oz as well.

                        I used HF weights which are large and contain no lead. I split each weight in half and placed them on both sides of the tire. This made it so they were flat on the rim.

                        Tires are balanced nicely now. Still bugged about the weight it took.

                        I didn't have the disks on the wheels when I did this so I'll check it one more time when I install them just to make sure. Shouldn't matter.
