rear tire question

[Funbaldguy]

 The 5th on my way to work I developed a flat rear tire. pulled into gas station called my wife. she packed up air pump and headed out we pumped it up 3-4 times to get to dealer who was closest.  been there over the years many times never used as service though. Arrived half hour before they opened. they had me come in and get started filling paper work anyway. left the bike at 10am. stopped back just before 2pm. it was ready but no one had called. my valve stem was bad. the new one has a support. I have been noticing that at times it still seem wobbly like a flat but it is not. slower speeds like in first getting going. this worries me a bit. but yesterday  I was noticing that my wear pattern has seem to drifted to the right side of the tire instead of middle. after my 200 mile ride. is it possible they missed something on putting the wheel back on?? or am I just being paranoid?
 another  thing they charged me for two valve stems and only put in the one. I didn't notice this till I was home.

If you have a way to do it, get the rear wheel off the ground and spin it while watching for trueness.  Most tires have some bands next to the wheel to help with this.

If you're not comfortable or don't have the way to do that, go back to the shop and ask them to check it.  You got to go back to get the money for the second valve stem anyways.

Have you checked tire pressure?   Or check to see if they mounted tire going correct direction?

Both my rear tires have shown a difference wth the ware pattern on the right side more than the left. I run 42/44 psi on my rear tire and ride 2 up. Have you checked the rear shock upper bushings, it could be coincidental, but if you remove the upper bolt you will be able to see if it is worn out. As far as the valve stem, I always replace it during a tire change (cheap insurance) and that plastic support is there to stop it from moving around. That could be the second cost of a valve stem (holder) when you looked on the bill.

Both my bikes have all metal valve stems.  I wouldn't let anyone ever put an OEM one back on. Long story short I had a rear and a front fail.  Never again. I even have spares so in the event I ever need to replace one.

My guess is the wear is weird from running at real low pressure.  Keep it at 40-44# and see if it straightens out.

Next time, buy these when there is a sale, no shipping. Get about 3 sets.

They last a long time, but you are more likely to give away the spares to someone else. The OEM valve stem is suppose to be changed out with every tire change (10K miles). Either yours was too old or never changed. Metal stems do not need the support, but most still leave them on.

Next time, if you can find the time, ask here first, you'll know more when you go into a shop. I'll do everything I can to not bring my bike into a shop, they just don't know enough about it, and even if they said they do, the proof in the future that they didn't could end up costing you a lot of $$.

  FBG , start over. If they removed your rear tire and rim to put in the stem , if is probably installed wrong. Get the Jake Wilson stems now. If you can't , PM me and I will send you a set. I install them on the bike in 15 minutes per rim. I usually talk to much when I do them.  If they did not use the proper tightening sequence , you are looking for early failure.  If the tire is a Dunlop, (dunflop)    that kind of wear is common.

ok sorry I took so long.. life seems so busy. just finished celebrating grandsons 5th birthday.  I finally got around to checking the air pressure. 34ish. not the37- 38 I was looking for. after pumping it to that point all seems fine.. thank goodness. thanks to all for the feedback. ride on, be happy

37-38 is still too low to prevent cupping and premature wear. 42-44 is more like it if you want a smooth ride and maximum miles from that tire.
