I got a nail in my front tire today. I was able to plug it and inflate it and its holding air. So I decided to inspect the rear tire while it was on the service stand. pon inspection it apears the rear tire is cracking were the treas is and coming apart. It's not dry rotted it looks like someone to a razer blade and cut little slits on the part that contacts the road. Note I just bought my scooter in about 6 months ago it is garage kept and has never sen rain. This is a quality issue! The back tire also has a nasty vibration if you go over 30mph. With only going over a little more then 1200 mi and paying 2400.00 after dealer costs you would think the tires would have held up longer then they did! Now I have to spend extra money that I shouldn't have to on new tires due to the fact that kymco cut corners by using generic tires! I'm going to get the Pirelli Diablo Scooter Tire - front and rear tires. They are going to set me back a 145.00. The bottom line is if you buy a kymco plan on spending money on replacing the tire because the ones from the factory suck! :-[
-
I would limit that complaint to your specific scooter, since I'm on my 2nd Kymco, and while
one DID come with low quality tires (Agility 125, CST tires), they did not crack or wear
unevenly or show any other faults when I replaced them in 2010.
At that time, the scooter was 4 years old, has sat on on a showroom floor for 2 years
and I've put 7000km on it from 2008 to 2010 before replacing them, purely because I
wanted more grip since I ride all year round.
On the other hand, the Kenda tires that I got with my Downtown 300 are great.
I've also ridden a test bike with 6000km on the same Kenda tires and was amazed
with the grip. I did NOT expect that. I got worse tires on my 650cc Kawasaki!
p.s. Cracked sidewalls usually happen because of under-inflation.

How do you like those diablos zombie? I bought this for my rear tire: http://www.amazon.com/gp/product/B001Y401NC/ref=oh_o05_s00_i00_details (http://www.amazon.com/gp/product/B001Y401NC/ref=oh_o05_s00_i00_details)
Very similar tread pattern. I'm not sure if I'm happy with it yet. Great dry traction but I don't know about wet. I ride extra extra careful in the rain anyway, so I haven't pushed it. I don't really think any of these sport tires have good wet traction. I looked at those diablos but they didn't have a 120/80-16 rear. They do have a wider than stock 100/80-16 for the front. Still have good tread on my stock front tire though.
I love the extra width. It barely fit. I had to cut off some of the inner fender to make it work.
-
Wider is better! I like the Pirellis. It took a while to tune them to the scoot tho. They run at 41psi cold, and felt like solid rubber to me. I now run the rear at 36psi, and the front at 34 (same tire on both)
I considered the shinko but couldn't find any REAL reviews. Look up your tire sizes at Bike Bandit. They have the BEST prices I could find, and I spend HOURS looking for deals.
Oh yeah the Pirelli's are terrific in wet conditions. It's been rain/fog for the past 2 weeks here ALL DAY EVERY DAY. The Avon Vipers felt softer on dry roads but were like steel on concrete in the wet conditions. As long as I get 1 year out of the Pirellis I will stick w/ them
-
Ps... Kenda's SU(K. Non fuel proof rubber on a TIRE!
-
Yeah, I know the Kendas suck.

These Michelins look interesting. http://www.bikebandit.com/michelin-city-grip-scooter-tire (http://www.bikebandit.com/michelin-city-grip-scooter-tire) No 120/80-16. I'm a sucker for Michelins on cars and trucks. They're usually expensive but worth it. BFG sucks almost as much as Goodyear(IMAO)
-
The city grip was actually my second choice if they didn't have the Pirellis in stock. 3rd would have been the no sidewall pirellis. (?26/?36). I kinda like the "fat " look tho. (just on bikes)
-
I got my agilty 50 back in 07 and just replaced theam last summer with kendas also.I love theam they
are the same tire you would see on the honda ruckus. I ride all year and they are good for all seasons.
-
Just don't spill fuel on them. They swell like balloons on the affected area. Takes weeks for it to return to normal

you shoulden be washing your tires with fuel they make soap for that.
-
Well the big advantage is if you don't like the result just drop a match, and walk...
Really tho...I had a leak at the petcock, and the fuel drained on the top of the tire soaking the whole thing. When I rode off in the morning the rubber separated from the carcass. I was a rubber shell on top of an inflated poly tire.
No more Kendas for me. Not on a 60mph+ scoot anyway
-
mmmm my scoot has a drip pan under the petcock that stops gas from going on my tires.
theres even a over flow pan if I fill to full at the pump it well dran to the side.

I just ordered a set of perelli diablo tires from my local scooter shop. I used perelli's on race cars and race bikes so I think they should work well for scooters. I will write a full review on the tires and post it. I will also update it through out the tires lfe. It should be interesting to see how they hold up and how they are in wet weather. I hate the stock tires! The vibrate the scooter if I go above 40 mph, They suck and skid in the rain and the ruber is seperating on both tires. Niether are dry rotted and niether have cam in contact with gas.
-
I for one am eager to see your opinion. What size are you using? I don't want to influence your opinion so I will simply wait...
-
I have herd a lot of good things about perellis. Nice street tires.

I actually read many reviews that stated "short life span". I attribute this to their "nature" being a high performance tire. MOST performance parts have a shorter life span due to working much harder than their OEM counter parts. ( HA HA ) oem "counter parts"
-
Ive been running Bridgestone ML50 Molas on my A50 for about 6months now and they are a big improvement especially in the wet over my stock tyres. Seem to be holding up well too on their treads after 6months use. I would definately buy them again.
-
..ive always been quite satisfied with Avon Viper Strykes...
..they stick like glue, even in the rain...
-
I loved the avons. Just wanted to face lift the whole scoot.
-
The Diablo's are nice even though I only have the front tire on so far. I ordered them and 2 front tires showed uo si I sebt the ibe from tge rear back.They dont make thre stock pirekki duablo size 120/180 /14 so I ordered I49/80/14, Cornering is much easier buy I will write a filll feveiw anfyer I get noth on

..lmao....

I have both pirelli diablo tires on the bike the look great and handle even better. On the back I had to go with a size other then the original so I went with a 140/70/14 and that is huge compared to the stock tire ( wider and taller). This tire is such a big difference I had to remove my fender. I think the bile looks 10X better . On the ron the is a 120/70/14. No more vibrations at high speeds! The scooter also sits up higher so you can lean more in the turns with out scraping. I smply love this tire set!
-
Will a 150/70-14 tire fit on the rear of a Super 8 150?
Also, what is the largest tire that will fit on the front of the Super 8 150?
I want larger diameter tires for smoother ride and less rpms. Realize I will lose some acceleration and not worried about the trade off.
-
It's unlikely that anything over 1 size wider will fit.
I'd be very surprised if 150 rear would fit.
If you want larger diameter, stick with the width, get 1 size taller.
You will gain some smoothness, but you'll loose A LOT in the handling
department with any of those mods, considering it's even possible.
Mods like that are usually illegal too.
You're better off just deflating them a bit then changing the stock size.
There's tires that are smoother and more comfortable.
I've gained a lot in that respect going from stock CST to Michelin City Grip
tires on my 12" wheeled scoot.
-
Why would increasing the tire size be illegal?
I'm baffled why the handling would be way worse. If you have experience to share on this, I'd like to hear it because I don't want handlling to suffer badly. Everything I read says a taller tire won't have the steering response, but will track better. A 150/70-14 is only an inch taller than the stock 120/80-14 that is on the rear of my Super 8 150. There seems to be room under the rear fender. The extra width also seems to "fit". a 150/70-14 is 15mm wider on each side and best I can tell, there is enough clearance there too.
It would be good to hear feedback from someone who has "plus sized" their rear tire.
Thanks for the input!

Check your registration papers/documents, if the tire size is specified there (it should be), then
that's the tire size you need to have on your scoot to keep it road legal. At least here.
As for handling, I've ridden ONE 250cc scoot whose owner swapped the rear 14" wheel
going from 130 to 140 width. It made the scooter turn in a lot a lot slower (it basically
resisted direction changes a lot more then before).
Taller wheel will also change your gearing.
Those tires will also be more expensive.
There's a good reason manufacturer decided to use the tires that you
have on right now, and it's not one of those things that should be messed with.
But what the hell, try it if you must.
If you want more comfort, change the seat, not the tires.

No tire police in the US :)
I have a 120/80-16 rear tire on my people and love it. 100/80 is stock. The 120 width is actually quite a bit taller than the 100 width even though the aspect ratio is the same. I have a Shinko SR568R. It's been good to me. Haven't lost traction yet.
As far as handling, no noticeable difference in steering response. I'll tell you, I can lean much much further into a turn now. Before, my kick stand would scrape the ground all the time.

That's exactly why it's taller. :)
You had 80% of 100mm before, and now you have 80% of 120mm.
It's 16mm taller, or 0.6".

Guys, any comments on the Duro brand scooter tire? I've seen them here and not familiar with the brand. Thanks!
I'm searching for new tires for my Super 8. I can't wait for the original Cheng Shins to wear out, it may take a hundred years. These tires are tough but quite slippery when wet. Rainy season is coming, that's why.
-
How many miles are the original Cheng Shin tires lasting on a Super 8 150cc?
I have 1300 miles on mine, front looks great, rear looks good too. I ride conservative.

They'll never wear out, but will try to kill you repeatedly after about 4000 miles.

Ah! makes sense. Hence aspect ratio. Duh!!!
Duro makes good tires for 4 wheelers. They last. Not sure about they're scooter tires though.

That's why they last a hundred years, the scoot and rider died.

I just put a 150-70-14 on my Kymco Super 8 and it fits… Did have to modify the splash guard on rear tire. Handling is fine better if anything as I have exactly the same ratio as before with a slightly larger from tire. One thing I did definitely notice is that take off is slightly slower and RPM slightly lower for same speed.Highly recommend this tire over the original ride is so much better and smoother. For a good place to locate this tire try Chaparel my brand is Shenko sort of like the Cheng shin original which I got 5000 miles out of on pavement roads and it was still legal when I took it off. Front tire still going at 15,000 but is getting close to tread marks. bought a Michelin 120-70-14 City Grip and it lasted 2000 miles and was toast (Illegal) so didn't have a good experience with the Michelin thought maybe I got the wax prototype it wore out so quick… I ride all year long Rain Snow shine -20 doesn't matter if it's not fresh slick snow thats slicker than… I go. Hope this helps all who are seeking this answer. I looked for hours and found surprisingly nothing or no one who's tried it. Was shocked it actually worked… (literally Shocked) Praise Kymco for their insight to engineering a great scooter that performs well is easily adaptable to oversized tires and designing a scooter that can withstand a crash and still come out not badly scathed. Well done in their design.

Did it make any difference in top speed? You've effectively increased your gearing quite a bit.

Can you give us some pics on the modifications and details on what you had to do. Please.
