Tires seems out of alignment
 
I am new to cycling and I have a question regarding the alignment/truing of my tires. I often use the front quick release on my to remove the front tire to allow me to fit my bike in my car easily. Is there a way to easily put the front tire back on and keep the wheel straight? There is a slight wobble on the tire when I spin it after I put it back in place. Any help is greatly appreciated.

Are you talking about The wheel or tire?

I guess the wheel is the issue. I apologize, I'm still learning more about the sport.

Not sure what you're asking? Most tires (i.e., the rubber part) aren't perfect and they do appear to wobble slightly.

The rims should ideally be wobble-free, although there is some debate regarding how much wobble is "acceptable". Adjusting any wobble in the rims requires a spoke wrench though; just taking the wheel on and off wouldn't affect this at all.

If you take your wheel off, you want to be really sure that it's fully seated in the frame again before you clamp the quick release back down. I usually open the QR "wide open" so that it slips in and out of the frame a little easier.

Removing the front wheel and reinstalling will not cause any problems. I do it all the time.

Might be time to have a bike shop true the wheel.
My bike shop does it for $15.

Yes, DO NOT use the quick-release to position the wheel between the pads. Shove the wheels ALL THE WAY up into the dropouts and clamp the QR lever down TIGHT.

Misalignment of the wheel between the brake-pads can be caused by a number problems:

1. brake-caliper not rotated to have centerbolt centered on fork & frame

2. brake-caliper springs weaker on one side than other. This is caused by ADD/rushed mechanics using a punch to bend the spring on one side to center the brakes. This is a quick & dirty way to do it, but causes other problems in the future.

3. brake-cable too short can cause one arm to be pulled to one side.

4. wheel needs truing. That is, the rim will move side to side between the brake-pads when you spin the wheel. This is fixed by adjusting spoke-tension

5. loose wheel-bearings can cause similar symptoms to out-of-true rim. Best to check & adjust the bearings 1st to verify they have no play.

I think we need a video of the wheel wobble.

Thanks for the responses, sounds like I need to take it to the LBS to get trued.

To get the wheel fully and repeatably into the dropouts, hold the bike vertically with the wheel on the ground and press firmly down on the frame. Then secure the quick release. The quick release nut should be adjusted such that the lever takes considerable force to close; it should make a mark on your palm when you swing it closed. Having the wheel in a predictable position will ease further troubleshooting.

Don't try to mount a bike wheel with the bike upside down. Be sure the axle is fully seated in the dropouts.
If fully seated and the rim wobbles the wheel needs to be trued and spokes tensioned. The rim should be centered relative to the axle lock nuts. The brake pads should then be centered relative to the rim, not the other way around.

there is problem if you using qr when you try to putting back into your fork sometime not align in center anymore the solution is don't release your wheel and buy car bike rack :thumb:
