Lots Of Weight Added To My Rear

Not my a$$, but my rear wheel! Had a new PR2 mounted up on my 5 spoke rear wheel at Cycle Gear yesterday and they used almost an entire strip of the stickon weights! I have never had more than 3-5 of the 1/4 oz weights added to this wheel. Does this seem unusual?

It does seem unusual. Got any pictures?

Not until I get home tonight...

Mounted a set of PP3's last nite and the rear tire started out that bad so I deflated it twice and kept moving the heavy spot until I found the light spot of the rim(I had aleady mark the light spot of wheel) it took 3/4 of ounce to balance.

P.S. yeah thats alot of weight.

Possibly a bad wheel. Excessive overlap in the radial belt ? Investigate this before trusting it !

Yes, it does seem unusual. They should have tried moving the tire around the rim. I would estimate that the tire is off balance and the wheel is off balance. It sounds like tire and wheel both wound up at their heaviest spot.

As long as it's balanced it's only a visual atrocity. Probably needs to be spun as switchblade mentioned. Get them to re-balance it

I'd take it somewhere else, doesn't sound right at all.

You know Cycle Gear started out with awesone custmer service and even better prices on parts and services but now they have turned into crap. Not long ago it was $10 a wheel for mounting and balancing( didn't pay to mount your on) but now its like $30 a wheel and the do a $hitty job.

+1 Used to love Cycle Gear about 3 or 4 years ago. Now they carry nothing good and do nothing good. I buy basic maintenance parts there (lube, oil, filters, etc.) and nothing else. Sad to see them tank so far so quickly.

And yes, that's a lot of weight. Get it done again somewhere else.

A lot os shops do not have the right tools to mount a SSSA wheel on their balancer. Was this the first time you had them mount a new tire?

Nope, they have done a few for me. I think they just lined up the heavy side of the tire with the heavy side of the wheel and were lazy. They should have broken the bead and rotated the tire and remounted it...

Dang man your luck has got to change, next week for sure !!!!!

I probably just need to walk away from the bike for the next few days...everytime I do something, I cause a problem! LOL. Now I wasn't going to tell you about how my voltmeter registers 13.8V steady when it's running becase BLS said that was on the low side of being OK.

But hey, I bleed the clutch fluid and everything turned out OK!!!

I mount my own, I always try to find the heavy spot of the rim (no tire) and then match it up to the mark on the tire, very rarely is it the valve steam that is the heaviest part of the rim, but that is the assumption some shops use. Others just mount them up and stick on the weights. Most large shops are a crap shot, might have one good tire guy and several bad tire guys. Smaller shops tend to have just one tire guy.

You know Michelins don't really have a "light spot mark" like most other brands. The only thing I see is the Ber Code label on the bead area and use that, not sure if it's the light, heavy or anything at all.

Never needed that much weight on a Mich.

I do the same. Would be great to know if it's significant of anything. Seems to take a bunch of weight to balance my PR tires, bunch = 1.25oz or so.

I have had to take a tire/wheel back to my local Honda shop for a rebalance. It was fine until I hit about 80 and got the shakes. They tried to tell me it was my steering head bearings. I had to tell them that it wasn't that way earlier and just about wound up in a wrestling match with the GM over this. They SENT IT TO ANOTHER COMPETITOR'S DEALERSHIP for another shot at it. It came back perfect. Needless to say, Britt Honda of Littleton, Colorado is now a Doggie Daycare facility.

The PR2 on my 5 spoke has 1 1/2 oz's on it and the other with the PR3 has 1 3/4 oz's.

Did you mount and balance it yourself?

I just got new tires front and back PP and PR2. I had them mounted and balanced at the local bmw dealer and when I went to pick them up at the arranged time, the guy I usually deal with said it was going to be a few minutes as the tech was demounting the tire to spin it on the rim as it was taking 4 ounces (2 per side) to balance. I waited till they were done and he brought it out with 3 ounces(1.5 per side). I tried it on the highway tonight and was not happy with the way it felt so I came home and spun it up on the center stand, first at low speed and couldn't see any runout in either rim or tire. I then spun it up to speed and sure enough, it was shaking like the proverbial dog licking sh## off a thistle. I peeled 3 of the 1/4 oz weights off each side and tried it again at speed, taking it up to 160kph. Much better but still not perfect so I took all of the weights off and tried again. This time it was almost perfect and I think I'd be satisfied as it sits. I guess this is a cautionary tale about trusting your balance agent.

Those that rode with me on the Victoria to Bonneville salt flats run will recall that I was complaining about a shuddering at speed. Half way through the trip, I got a nail and had a proper patch and balance job which seemed to make the shuddering issue better but not fixed. Recently, before the tires were replaced, I had an opportunity to test at a significant speed and it was almost scary the amount of shuddering from the back end/seat at 80-90mph.

Now, finding this issue with a new tire and new mount/balance, I'm wondering if there is some irregularity with my wheel that makes it hard to balance? I'll pull the rear off tomorrow evening but in the mean time, does anyone have any suggestions as to the possible issue resulting in three bad balance jobs?

I would not think that it would be the wheel unless it has done it all the time. I have used dynabeads or the cheap knock offs and I have never had any tire balance issues....Even at significant speeds :wink: that might be worth a try I hope you get it figured out!

Sounds like your wheel to me. I'd pull it and take it to a straightening outfit and have them check it.

Well, the ride to work this am, I was able to test at about 120 k and it was smooth smooth so I think the balancing shop just screwed up. As to why the seemingly recurrent problem, I'm now thinking that the nail in the tire was causing the first issue on the Bonnevlile run, followed by imperfect balancing when I had the tire patched. On the recent run, I now realize that I found another nail in the tire afterward so that's probably the answer. Like I said, I didn't see any runout in the rim or tire. Just got to figure out where all the damn nails are coming from because this makes three in the last two years as the tire that just got replaced was itself installed due to an unrepairable nail in the previous tire.

So you were able to do a little testing :unsure: the unbalance would be a good thing....if you had the beads in you wouldn't know you had a nail :cool:

V-FORE

Well then maybe we would have stayed on schedule last year, at least till the nail came shooting out like a bullet on some of our spirited adventures. :cool:

I've been doing a little reading and it seems folks are having good success with airsoft pellets. One guy even said he put golf balls in his 4x4 tires with good results.

Had my rear wheel balanced on Saturday. When the PP was fitted the balancer machine was not yet in (new shop starting out). I did notice some imbalance it at certain speeds so now the machine was in, it got done

It needed 35gramms on one side and 15 on the other.

Got the rattle can out to hide the weights somewhat.

So if deflating the tire and rotating a bit will eliminate -some- of the imbalance, I will ask him to try this next time/tire... :cool:

Next time before he inflates the tire put it on the balancer and see how far out it is . I like to put it on the static balancer and see how hard it swing's down to the heavy spot and it does rotate down fast then I put back on the tire mounting machine and rotated 90 degree and check it again ..

Some OEM wheels are way out of balance. Pirelli on a Dymag showed less than 1/8 oz, which is close enough for me. Pirelli on Suzuki wheel took 4oz's, removed the tire and there was no difference. The wheel was out 4oz's (8 weights). Now I balance wheels first to find the heavy and light spots.

I recall a few years back sending my 250 in for new tyres, when I went to pick it up the mechanic greeted me with a concerned look on his face and an "I tried to balance your front wheel, but there are 3 major buckles here, here and here.. you should look into finding a new one ASAP"

So that was.. encouraging :P ended up blowing the engine before I found a new wheel anyway

Back to wheel weights though, every time I've balanced one myself I always aim to get within 5 grams.. the OCD occasionally kicks in until the machine reads '000'.. but even with wheels that are significantly out with zero weights on I've rarely noticed the difference.

Old bike / new bike / old car the imbalance wasn't noticeable at any speeds. Brand new car that can cruise highways with negative decibels inside started to hum a little as if the road surface was a bit rough, but didn't vibrate at all.

Either way I wouldn't worry about having a few extra weights on the rim, as long it drives nicely.

Spray paint on your newly powdercoated wheel???

I taped off the rim and any stray paint removed with some terpentine! I like a clean rim! :goofy:

There is actually black colored weights awable, so no spay can would be needed. I had the guy that painted my wheels HRC gold paint a few weight straps same color to get a nice look as i change tires.....HRC gold weights not awable in shops....

And this is why I use Dynabeads. I just drop 3 ounces into each tire and I'm done. Smooth as silk!

FYI I have tire pressure sensors in my wheels, hence the need for 3 ounces.

Time to trade back to VFR ?

Fact 1... Tires are elastic bodies and cannot be produced absolutely

round without imbalance. Therefore balance is paramount after fitting

a new tire...

Fact 2... Dynamic balancing is the preferred method because the wheel

is rotating and measures the deviation of masses with respect to

center...

Conventional wisdom states that you align the dot (lightest spot of the

tire) with the valve stem (heaviest spot of the rim)... true but

deceptive... your wheel's heaviest spot may be independently of the

valve stem which can be learned if you first balance the bare wheel...

Now what??? well I marked the heaviest spot of the wheel with the

letter "R" so I may align the tire's lightest point indicated by the

Red Dot...

Why all the fuss??? by aligning the heaviest spot of the wheel with

the lightest spot of the tire you add the least amount of lead weight

to achieve harmony balance... weight is the enemy especially on a

spinning wheel... it negatively effects acceleration... suspension and

braking... to what degree is mainly tied to the level of your

sensitivity... if you don't care then you don't care... it doesn't

mean it doesn't effect your machine...

But what if my tire has no "dots"??? Some tire manufactures skip the

expensive step of adding the "dots"... but that doesn't mean your tire

was produced absolutely round... quite the contrary... you still have

to balance because a Unbalanced tire/wheel assemblies can hop at

certain speeds and greatly accelerate tread wear...

How much weight is too much??? if you employ more than 3.5 ounces of

lead weight which is 14 1/4oz stick on lead weights to the tire it can

be judged defective in manufacturing and you may request a refund or

replacement... contact the seller and state your gripe...

Ive seen no evidence the barcode is of use on Mich's, with my own installations. out of dosens of powers and road 2's the weight seems to be fairly similar and in the same place, as a general rule. If I wasn't so lazy Id balance the rim itself, it would be a lot simpler afterwards, little to no weight. All tires ive ever mounted all seem to need weight in the same general area.

I haven't used cycle gear for mounting for many years, they used to be about $30 if not bought from them and about 20 dollars if bought from them, but that was many years ago, I think nowadays they are $30 for even there tires, or higher if not.

The problem with their mounting, Is employee turn over rate and inexperience, the last time I used them they tore the bead on my tire. But whether cycle gear or the dealer, they all are pretty bad with balancing IMO. they normally get the weight in the right place but its not right.
