Title: Odd rear tire wear
Post by HighME32 on 10/24/14 at 11:43:21

Hi All,
I had some really wierd tire wear on my 07 s40 ryca cs1 conversion. I was running the Kenda Cruisers on them and after a little more than a year the of riding about 60 miles a week the tire was baldong one side of the tire (front) and fine on another (rear). It was not a side to side wear issue. The mechanic at the shop that installed my tire thought it was from doing burnouts, but that has never been dome on this bike. Any ideas?

Do you feel a "Pulsation" when youre stopping? If the brake is grabbing harder in one area of the drum it will wear the tire like that. I had a warped rotor on a work truck ( company owned) and I noticed an area on the tire that was wearing faster and when the rotor passed thru the pads it bumped Juuust a little,, You might need to get the rear tire off the ground, in neutral, spin it, mark where it stops ( chalk line/swing arm, whatever) spin it, see if it stops in the same place. Then, if nothing shows up, adjust the brake a little tighter till its either ON or ya prove its not the brakes doing it. Problee otta mark the threads on the rod so ya can get back to "Square One" w/o a hassle when yer done..

I am confused. The heading says the rear tire had odd wear, and in the post the rear tire was worn evenly and the front tire was worn on one side?

Splain' this a little slower so me.....so I can understand what was worn "Odd".

I'm thinking he could have said Top and Bottom,,IOW,it's not a left and right sides of the tire issue.

Exactly, I meant the tire wear front/back wear imstead of side to side, so along the diameter of the tire the wear wss different.

Justin,
I haven't really noticed pulsation, but I did readjust the arm on the drum to go back more to decrease the play in the ryca rear brake lever. It isn't binding when I roll it. BTW ehat is an easy stand to use to get the tires off the ground?

Did you check the balance on your wheel/tire set up? Riding with a tire that is out of balance can make it wear uneven.

The RYCA pedal set up for the brake is goofy.....it needs a stop. I used Dime City pedals and built a stop that works great......Since you have a RYCA peg/pedal set - you need to build a stop like Gerry did.

There is a piece of aluminum on the back side, a threaded bolt, and a clear rubber sleeve to soften the return impact. It puts and end to all that "limp pedal" nonsense.

Yeah,it's supposed to be balanced. Whoever mounted it probably changed to balance it. If you're okay with the brake, then next thing to look at is balance.

The new tire is balanced. I saw them do it in front of me. Thanks for the info on the brake Dave! I will definitely look into getting that.

The only way you can get it......is to build it. Or ask Jerry to build you one. RYCA does not make this part - but they should.

I just noticed today that the drum is rubbing when i roll the bike. I have never had this happen before but it doesn't sound good. I repositioned the drum brake lever (took it off of the teeth and replaced it) maybe 15 degrees to get it the way the initial ryca brake adjustment set it. I had a mechanic install the rear tire recently and the drum still looked like it had a lot of pad left. I am going to take it apart and get the ryca brake pedal stopper. Any ideas what could have happened?

You guys think it could be the bearings? I guess I'll find out when I take the rear tire off

Hey Dave,
Ryca is charging 25 for that brake stop. How much do you think it wpuld cost to male Gary's? Should i even try or just buy one?

Title: Re: Odd rear tire wear
Post by Dave on 11/14/14 at 19:41:56

RYCA really should send those to anyone that bought a kit that did not include one..........

Send me the distance from the back of the rear set mount to the outside edge of the brake pedal, and the distance from the center of the bolt in the peg to a point about midway on the lever that actuates the rear brake...and I will make you one. You will be the test subject!

That's real nice of you Dave! I actually sucked it up and just bought one because it would probably take longer for me to get one. So as far as the drum rubbung when i roll the bike. Should i adjust the pedal height or just take the drum apart to see whats going on?

Soo,, I had it..

I guess he's trying to say either his wheel & as mounted tire is out of round (radially) in some really significant fashion or his tire itself wasn't made/cured correctly and it simply wore in an very uneven fashion as rotated.

Or he's saying something else entirely, in which case he should try explaining it again.

???? :)

You might be right Justin. It's odd that there is some grinding noise coming from my drum when I roll my bike, but it is on one side because I get free rotation until i hit that patch. An idea what ot coud be? I just got a stand, so im going to take it apart tomorrow.

Oldfeller, yes my rear tire was not wearing evenly radially. They guys at the shop i took it to didn't see any problems with the truing of my wheel. One thought i was doing burnouts on it. When I troubleshoot the rear brake grinding tomorrow, ill check the truness with zipties attached to the swingarm.

I just noticed that the return spring on the rear drum arm was missing. Luckily i found the part. This is probably what has been eating rear tire up unevenly.
