Popular Post DjPanJan Posted February 1, 2021 Popular Post Share Posted February 1, 2021 (edited) I used only one side of the EUC to replace the opening. CST 1488 stock tire rubbing when one leg riding: CST 1488 stock tire pattern was still good after 2200km "propably" but I wanted MSP to be more nible. The weight of michelin city for 70/90 R14 is 1874 grams Stock 1488 1322grams (even with dirt between pattern) (after job done and tire inflated to max allowed psi) Here is a setup for centering the weight using a moto weight 1, kitchen weight 2, board 3, wooden blocks. Used @mrelwood guide. I centered it on the rim using a ruler and a line on the tire to make it as straight as possible. + -1mm it fit all over the perimeter. Then I slightly inflated the inner tube and checked again. Finally the work is done and the beauty is on "MSP" spinning perfectly no oscillations or vibrations. No rubbing one leg ride perfect. Here is patern front VS rear i use rear direction (right on picture) I haven't ridden it outside yet. The weather here is extreme, everything is freezing. From home testing the first impression is distorted I inflated to 44 PSI (over tire max recomended) to fit into the frame. So it was almost uncontrollable and extremely nimble which is logical with so many PSI. After 1 hour my shaomi pump say 41 PSI 3psi loss i dont know if is coincidence i be watch longer time if slowly leaking somewhere i check iner valvefirst if ok i just slime it in future. I buy new inner tube because old one was slimed. But for balancing need tire without slime ,liquid inside completly block posibility to find most weight spot to counterweight this spot. After i ballance all positions tire is +-2grams. Before ballance 9 grams diference on one spot. What confused me a lot is that the tire can be given from two directions. Originally as a front or rear wheel on a motorcycle. I chose the direction for the rear tire I hope I didn't mess it up. I thought I would test it at worst by riding backwards MSP as the tire behaves in the other direction reaction noise, nimblenes etc. This topic is not finish (yet) i plan add moreinfo and small review this michelin city pro tire.

Also it was not zippy anymore. Not sure if the weight was the only reason. The lighter CST-C186 has much less gyro feeling and is zippy enough.

Shinko SR-244 has no sense on EUC imho agree on CST 186, really easy to tilt and fun to ride 2.1kg on my scale 1 Quote Link to comment Share on other sites More sharing options...

I had all weighed and posted it somewhere, but unfortunately can no longer find it myself. My memory is really miserable. Than the Shinko is even more than 2.1 kg Quote Link to comment Share on other sites More sharing options...

EUC Custom Power-Pads Posted February 1, 2021 Share Posted February 1, 2021 I found now one of my Facebook post and I wrote that the Shinko is 900g heavier than the CST-C1488. I have weighed my new CST-C1488 again and it's 1340g + 900 = Shinko 2222g. I thought the CST-C186 is much lighter than the Shinko, but it's only 100g. Hard to believe that this 100g difference is a the reason for the horrible gyro effect. Sorry @DjPanJanfor derailing your thread. 1 Quote Link to comment Share on other sites More sharing options...

Picture today after first 10 km. Fit great. Somewhere in my head is small tire evil who say me try 80/90 r14 try 80/90 r14 . I expect 80/90 fit but without my 3D printed fender propably this is choke point now on my MSP. I nonstop experimenting with pads i have ugly generic chinese one, and i dobnt like it at all. Since i buy them i try 100+ more try to fit my needs it better. After 10 km realy pre-view of this tire. I ride in -2 degree celsius what make tire material logicaly harder. I expect after 200km dynamics tire be changed is too fresh actualy "too virgin" The tire compound is stiffer on touch compared to 5167 or CST feel more solid if press hard force is aplicated to more "area" cm/inch square. Despite this, I was very pleasantly surprised how the vibrations from the asphalt really absorbed the noticeable difference compared to the CST 1488 very adult impression of driving. I inflated the tire to 33 PSI, which is definitely too much for sure, in time I will definitely go down maybe to 25 psi. I wanted to compare my CST 37Psi vs michelin to 33 psi. Gentlemen and ladies, whatever I wanted, I got it and almost too much! My MSP is now as nimble as the KS16X on the ChaoYang CYT H-5167 (he 35PSI) which I can compare and I did today. I almost lost my balance first meters this thing is nimble or without a gyro effect i dont know how say this . Feels like when you ride EUC on the grass super efortless to turn you know what I mean. Maybee like overinflated tire 45 Psi more. Turning on place is soooooo easy.(like on overinflated tire) All the way I drove slowly at most to 20km/h it's frost and I don't want to cutout with my weight. Tire is not silent +- same to CST in other rotation direction is noice more noticeable compare to CST loud.(shure not like sherman knoby) On the pavement it holds beautifully on the asphalt also on white (marking) on the asphalt too. Gravel good just tiny stones are cut in the tire pattern. This does neither the h-5167 nor the CST1488 at least I did not notice it before. During the test uphill and the stone medieval road incline to the church at a slow speed, it does not bounce as much compared to the CST. Plan drop to 30 PSI nextime and test as soon as the weather allows. When i look on tire deformation when i am on euc is almost zero this weight rating make good job. CST on 35 psi under me was visibily conical michelin no visibly change thsi mean i can go realy lower in psi experiments. I also tested the reverse rotation of the sample (+ - 1km) on asphalt and the tire seems noisier in this direction of rotation. Dont take all this seriously i am just noob who discover big world adult moto tyres. Simpy said i like this tire and feel of new EUC is here. Is MSP power + ks16x nimblenes hybrid happy me !

My shell opening measures 3.110". Not much extra room... shell alignment will be critical. Your 70/90 size sounds much less fussy, good call. 2 Quote Link to comment Share on other sites More sharing options...
DjPanJan Posted March 25, 2021 Author Share Posted March 25, 2021 @RagingGrandpa What orientation tire you use "rear" or "front" ? Becasue is front/rear tire and on motorcycle is using oposite patern for front and rear whell. I select same orientation what original 1488 have. (this mean rear rotation arow on tire) On my MSP looks 5mm on each side aceptable (gap is visible on photo) but as i say my 3d print fender be shure weakpoint. Original tire rubing when oneleg that one of reasons i decide 70/90 R14. I have some "fear" if chose "smaler" because was woried about riding characteristic ,but no this michelin is beter in everything i never want go back to 1488. Maybe big part is my weight with gear +- 120kg (260lbs) and compare to stock tire michelin not visibily deformate under my weight. Still experimenting with PSI after more km/miles i update this thread. Now is rideable outside again. Absolutely respect riders who like/love stock tire i speak here about my "Feel" and subjective personal experience. Anyway i hope you 80/90 fit and you enjoy this tire like i do . 1 Quote Link to comment Share on other sites More sharing options...

But it should only matter if the surface is wet... likely very little difference in grip between the two orientations. 1 Quote Link to comment Share on other sites More sharing options...

DjPanJan Posted August 4, 2021 Author Share Posted August 4, 2021 update after 500+ Km Excelent nimble tire.

(this mean rear rotation arow on tire) Opposing directions doesnt apply on single wheeled vehicles. Recently, manufacturers are suggesting opposed tire on 2 wheeled vehicles, to mitigate the feathering wear pattern that can be caused by cyclic vibrations from tires mounted same direction. This cyclic feathering does not apply on an euc. Mount the tire as you would suspect it needs be, for proper water shed, quieter running and better traction. Some tests show that air acts as water when entering a tire channel and being compressed to center. Tho traction isnt effected with just air, noise at speed can be. Not a fan of a center depressed/solid channel on a tire myself, but it surely makes direction of rotation a lot more moot.

Amarucide Posted August 23, 2021 Share Posted August 23, 2021 was your original tire at 18x2.5? i'm curious because I've been looking at 70/90 14 for my KS18XL Quote Link to comment Share on other sites More sharing options...

Funky Posted December 17, 2021 Share Posted December 17, 2021 (edited) So we know that City Pro 80/90-14 mounted and inflated on the MSuper rim is 3.058" width. @DjPanJan Could you please tell us the width for 70/90-14 tire? I'm looking for new tire also witch is better than stock 1488. Wanted to know it's width. Height would be around ~64mm? Would appreciate if you could measure it.

I'll sit with you waiting the same info Theoretically, 70 is the width of a 2.75" tire, not 2.5" of our KS18XL, so 70/90 is a little bit more than the stock tire width, to get the real dimension is very interesting. Moreover @DjPanJan, what about wobble with this tire ? Edited December 22, 2021 by digithom forget to ask last question Quote Link to comment Share on other sites More sharing options...

Moreover @DjPanJan, what about wobble with this tire ? City Pro 80/90 is ~78mm, 70/90 maybe is 68mm? Who knows, it can be also 72mm.. Luck of the draw buying unknown tires.. Height also from original 1488 18x2.5 tire is 53mm from where tire/rim meets. I would love to get closer 18x3 tire, but most of them width wise are to big for 18xl.
