I guess I'm mostly curious if others have seen similar tire damage,
..and if you think its a tire defect or not.
(oh and if I'm stupid for riding on it, or bah! it's fine!)

It doesn't look like it's super serious, but on a 2 wheeled conveyance, your tires are the most important part of the vehicle. I don't take chances with tires.

Were it me, I'd buy another Zippy 1 and use the f'd one for the spare. Get your money's worth out of them and then move on to some Pirelli's or be a cheap bastard like me and roll the Shinkos.

I doubt that is a defect. You would be surprised how big a cut a piece of Turtle shell on the road can make. Not to mention broken glass, metal brackets, roofing tacks, etc.
I bet it got cut on something.

I would not feel real good about riding on iy myself, it would always be on my mind. I would fell good about putting it on the spare rack and replacing it with a meaty new one on the rear. Then you would have a nice spare to use if the moment demanded it, but you wouldn't be rollin' steady on it till you found out how much it would take to make it go POP.

Post tubes and rims Reply with quote
hello all! i'm new to the forum as i just purchased my first bajaj chetak! as alot of you have recommended my first mission is to get those stock tires off of the bike. i have read, i think, all of the posts concerning tires and i have a couple of questions. i am going to order 3 of the pirelli sl26s. i understand these tires are not manufactured to be tubed tires, but from what i have read you guys put these on the stock bajaj rims, right? i saw a post where someone ordered rims and tubes and tires in one sweep. i was confused by that. do i need to order new tubes as well or can i reuse the tubes that were in the nylogrips? i don't understand the new rims threads so maybe someone can help me with that. thanks for your help. i'd love to get these off the bike asap. i am thinking this beautiful bike has some good handling hidden in there once i get those off.

It will be a new scoot with the Pirelli's. I used the stock tubes when I switched. They are standard 3.5 x 10's just like anyone will sell you. I went 28 front, 32 rear on the tire pressure. The recommended tire pressures from Bajaj are for the Nylo's only.

Although you could re-use the inner tubes that came with the Nylo-death tires, I certainly wouldn't recommend it.

The rule of thumb, as I've been told by shop owners and scooterists alike, is to always replace the inner tube when you swap out your tires.

In addition, you might think about buying some Slime and putting that in the tubes. It won't stop a leak, but it can stop a sudden blow-out. And after you've had one sudden blow-out, you'll be using Slime (or some other similar product) religiously.

Post to slime or not to slime Reply with quote
thank you rufusswan and matty!
on the slime front. is it injected into the inside of the tube? it's not like fix-a-flat right. it's just a goop that covers the inside of the tube? i think i will try it out. i like being on the safe side.
oh, and the whole new rim thing. you only need new rims if you've somehow damaged yours right? there aren't ones better suited to different tires?

Slime is this green goop that you squeeze into your inner tube before filling it with air. It distributes inside the tube as you ride.

New rims are only necessary if yours are rusty or bent. Bajaj rims are better than the aftermarket rims you'll find at SPD, ASC or Scooterworks, which are typically Prima rims.

Make sure you let the air out of your tires before you split the rims or else you can end up bending/warping the rim.

Hey mostly_lurking...

You might want to look at that tire and see when it was manufactuered. I'm kind of curious.

http://www.abcnews.go.com/Blotter/story?id=4813029&page=1

An old co-worker/car nut sent me an email pointing to a story that ABC News did about how tire distributors and sales locations may be selling tires that are over 6 years old. That figure is, in some parts of the world, accepted as about the maximum safe age for tires. In car tires, a too-old tire is much more susceptable to catastrophic tread loss at speed. Notice all those treads lying along the interstates?

Anyhow, the link I attached here shows how to read your tires to see how old they are. On cars, prior to 2007, this apparently was on the inside tire wall so you'd probably have to crawl under your car to see the date codes.

I checked my Bajaj scooter's tires. It's a 2003 model.

Original tires: Made in 6th week of 2003. Yea for Bajaj.

My new tires I put on last year in 2007: Made in the 36th week of 2006. Yea for Motorcycle Superstore's Michelin S83's.

I picked up the Pirelli SL26's as recommended. Bought the 100/90 10s - front and back. Picked up Slime from the bike store. The Slime company recommended 4.2oz for 3.5x10 tires and the bike-sized slime container was 8oz - so i just split the slime half/half in both tubes. Bought new tubes from Scooter World. Put it all together night before last.

Bottom line: love them. So much more stable at higher speeds. Sound from the road and vibrations are also greatly reduced. Put ~50 miles on them yesterday.

Anyone need some '03 Nylogrips with <100 miles on them? Smile

BTW - the 100/90 although wider, are a $1 cheaper, at $23.99, than the 3.5x10 from motorcycyle superstore.

Edit: Need to add a big THANK YOU to all for the input/advice/recommendations!

I have some new tubes for 3.50 X 10 tires, . If I switch to 100/90 X10 tire, can I use the tubes ? I don't see much of a difference, so correct me if I'm wrong....

The sizes I got from our local shop, Scooter World, were 3.5-4.0 x 10 (literally stated on box). Even if you get ones that are 3.5 only, pretty sure you are OK as 100/90 is like 3.57" or something not too much bigger (Monza has measured earlier in this post). Not sure I should be giving advice based on my previous experience with mountain bikes, but prettry sure as long as you buy the bigger 3.5 sizes you will be fine. You probably do not want to try the smaller 3.0x10 sized tube, though.

You will likely be fine with a 3.5x10. Inner tubes stretch and it's not a huge difference.

p.s.- I also installed one of these handy-dandy exhaust deflectors to try and keep the whitewalls white. http://www.scooterworks.com/Exhaust_Deflector_P3381C204.cfm

An interesting side-effect of installing this item is the growly/grumbly sound now emanating from my stock muffler. It sounds like an angry machine now.

This probably goes without saying, but if you put on one of these exhaust deflectors, be sure to pick yourself up a lock washer for it. That stock bolt and nut vibrated off in less than a week. (Had to pull over and grab it when it went clanging down the street.) I'll try and get pics of my scoot and accessories up soon. K


Kyle, or anyone else with the deflector

Now that you've used the exhaust deflectors for a while, how is it working? I just put the shinko whitewalls on yesterday (enter love of new tires vs. Nylos here) and would like to preserve their glorious brightness for as long as I can. Can't beat the price at scooterworks and I like working with them.

Thanks for all the advice on this board. It pointed me to cheap tires (3 + shipping for under for just over 90 at tires unlimited), saved my fingers and or rims because I would NOT have let the air out of the tire prior to splitting the rims, and made a job I would have taken to shop easy enough for me to do.

any one post a how to on replacing a tire?

I did a search but i didn't find much, just talk about tire types and what not. I'm looking for procedure cause i have to venture into this. the owner before me rode the crap out of the nylodeaths.

I was thinking of getting some Pirelli SL26s cause they are a little cheaper then Zippys and i'm going for the battle scooter look, not the I Talian classic look.

second question: can i use the stock rims or do i have to buy some new rims too?

Your stock rims will work fine. So will your old tubes, BUT everyone recommends new tubes. I wouldn't hesitate to slap new ones on. You may find (as I did) that pulling off the old nylo's revealed several patches on the old tubes. Luckily I had purchased new tubes with the new tires.

Not much to tire replacement, but there are a couple of things you need to be careful with, and there can be bone-headed things you should avoid.

Remove rim/tire and DEFLATE THE TIRE, that avoids exploding rims.
Getting the skinny rim off is usually easy and then you should be able to pull out the tube.
Getting the other one off is usually frustrating case the tire usually welds to the rim. A couple of big screw drivers and about one beer per thick rim is my ratio. Others have their unique methods for separating the two.
Clean the rims once shed of the old rubber. I generally rub them clean with warm soapy water and some sort of scrubbee.
Now is the time to rattle can them if you wish, same with the hubs. I did mine in black - cool.
Inspect and clean out the new tires as there can be debris inside the carcass which will eventually rub through the tube. Rub the inside of the tires with your hands to be double sure of stuff.
Be mindful of rotation arrows on the tires, and look for something like "E3" on the tire. The "E3" emblem should line up with the hole in the thick rim where the tube inflater sticks thru.

I use clean soapy water to wet down rims and tire and tube to make them easier to slip onto rims, and to help prevent pinching the tube between the rim sections. I try to push on the thick rim first, then slip in the tube and get the inflater out its hole. Then I like to put a few pounds of air in the tube. Only a couple of pounds, just enough so that it is not flat. If tube is a little round, and has wet soapy water on it, you should not pinch it when you push on the skinny rim.
At this point I push the rims together and install nuts only on the studs. Slowly crank them all down. Then I grab the tube inflater and pull it all the way out and start inflating the tube. Sometimes you have to fidget with things to get the inflater correct. Once all is well you can add air and set the beads. You can see the bead line on the tire, it should be uniform all the way around. Completely deflate the tire, remove nuts, add the lock washers, retighten, double check the tube inflater, and air them up to proper pressure.

Post Tubeless Reply with quote
I have a set of tubeless rims & tires arriving tomorrow... the first thing I will do is
remove the air from these wheel/tires and take them to Costco and have
them filled with nitrogen.
(It's all about the molecules, but that is another story).
I EXPECT these wheels to perform flawlessly ... I for one will feel much more
comfortable knowing I won't go instantly flat if I do hit something that causes a
flat tire.
Most of you youngsters... (oh hell, I can't believe I have finally used that term in my life)
Have never had the pleasure of a tubed tire going flat on them INSTANTLY...
I raced Triathlons on the U.S. Navy's 1st team and I am here to tell you... at 30+ MPH
a flat tire reaks havoc and does it right now!
So I decided to buy a set of these new 10"
tubeless rims regardless of the cost involved... .
*** more reports on the wheels soon***
IMHO- I wouldn't feel comfortable on anything less than tubeless at over 30mph...
Personal choice I guess... but for me it adds an additional amount of security, worth the
cost.

All I gotta say is I'm going to stockpile tires next spring in preparation of the summer months. Scooter tires are hard to come by now...at least in a timely manner.

Post Tubless wheels & yoko tires Reply with quote
Ah...so there is at least one person who is still talking to me...
I was feeling like I was in high school - nah... grade school... and someone passed a note & said don't talk
to him... he has kooties... haha

Maybe I joke around to much... but forums can be fun... can't they?

Anyway... back to the wheels and tires...

-Wombat...
Got the tires & wheels... very fast shipping (but very expensive at $152.00) from Vietnam
& www.ScootRS.com _

---However there is a new source coming online shortly)
More on this as soon as this new company has ramped up...

as for sccotRS... nice fit & finish... Powder coated wheels ..nice...

I decided not to get the stainless steel wheels at this time as scootRS has a disclaimer
stating the wheels are for show only and may be to brittle for everyday use or in extreme
climates...

I will say this... my tires & wheels showed up with 50lbs + of air in them...
when I lowered the air down to specs... immediately one valve stem started leaking...
Of course I didn't discover theuntil the next morning as I started driving down the road...
Funny how hard it is to turn on a flat tires....hahaa
Lucky for me I thought ahead and bought a second set of top of the line valve stems.
Breaking the bead was a trip at my local shop & the guy didn't really want to touch them.
We popped them open...and I swapped out the stems and perfect. I used a very tiny amount of silicon
around both side of the stem.
The Yoko's provide great road feel... there was a bit of a rub on a tiny bolt at first... It has since
not been an issue... I think it was rubbing when I first put the tires on with the 50lbs in them.

I am doing some fun stuff to my scoot and don't want to bore everyone with pix today...
I am hoping to have a number of fun modifications done by this time next week, that is, if everything
else arrives on time... then I will show my "Lil' Mule"...

And now back to a more serious note... to those I may have offended with all my Mighty Putty stories...
I apologize for trying to have fun... I will try to be much more sober from here on.
I just thought if others could cuss, bitch and moan, I could joke around... apparently that is not the case...
so... In the spirit of wanting to get along with each and every one of you I will refrain from being overly jocular.

and I thank you for your support,
