    alternative tyre to 100/80/14?????

    Hi Guys,

    I will shortly be needing a replacement 100/80-14 front tyre for my Mojo 150 GTiR - its still on the original Chinese front.

    I have just had it serviced byYam City, and they cant get this size of front tyre from their suppliers. Tried a host of other places and no-one has one in - and cant order them at all apparently

    so - is there another size that would fit and work fine without affecting things like my life expectancy or speed readings etc?!

     

    any advice much appreciated

     

    Cheers

    You could write to the manufacturer, they may or may not answer.

    My experience with bicycle tires is that a variety of widths will fit on a specific rim without issues within limits.

    I am wondering why the tire dealers you have asked haven't given you an answer.

    EDIT: I have found a manufacturer that makes 100/80 14" tires, CST but they specify rim width and I don't know what yours are so here is the web page of them. They have specified 2.50 inch rims.

    Edit: I think you need to match rim widths, a table of Heidenau tires  has 110/80 models K63, K66 for 2.5" rims. I have looked at guides for motorcycle tires and scooters seem to be similar, the other close sizes might be 100/90 or 90/90 (90 seems to be too narrow, it may be good if the specific tire states it can be used on 2.5" widths) for 2.5". If you need to match to the rear that I assume is also 100/80 then maybe you need to change that as well or handling may be bad. Cross ply front is legal with any rear (e.g. radial) or otherwise must match. Wider taller tires must fit between the forks, fork brace and mudguards. Taller front will slacken the head angle with wheel height going from 80mm to 88 for 110/80 or 90mm for 100/90 or little change for 90/90, may be significantly greater than this with variation from brand to brand. Speedo will slow by 3-3.8%, this may not be bad if speedo reading is too fast. Probably be more succesful if both tires are changed to match if clearances are good. 90/90 tires might be moped style, 100/90 is the same width but will they fit under the mudguard, the clearances need to be good, the tires will grow considerably when spinning. Don't really know that much just did some research this evening out of curiosity.

    Changing tire sizes will likely affect the handling, maybe not too badly but likely worse than the proper sizes or the tires won't fit the scooter.

    Probably best to ask tire shop people about the correct choice of tire.

    EDIT: Sava MC 38's come as 90/90 14" tubeless for front and rear, some 90 widths seem compatible with 2.5" rims but you will have to check with Sava if these ones will. The load rating is also only 46P, your best fit seems to be Cheng Shin C6577's or C918's that come as 100/80 14" tubeless front + rear with load rating of 48P.

    thanks for the info

    just checked and they have fitted a Michelin 120/70-14 on the rear (14inch front and rears) so the front and rears are not identical

    checked with the importer yesterday - they have no idea and reckon they are looking into it for me! they claim that the bike is  no longer brought in after 6 years - but you'd reckon they would still have an idea as to a basic question of what front tyre can be used if these sizes are no longer available?!

    I was looking at an old thread about your scooter here and someone provided a link to a description of it where they call it a CFmoto and the rear it says is a 120/80-14 not 70, but the front it says is a 100/80. The michelin scooter tires they sell here on their website that are 120/70-14 are all for the front.

    What is the model of that tire?

    The CFmoto version that has the same front wheel as yours was sold until 2012, so you should be able to get that tire I think so, and I have seen them selling so people have them, you might need to ask someone who has one where they get their tires!

    Hi dp20 Not sure if you have replaced your tyres but here is a previous rant i posted

    [Well just had a service completed and the tyres fitted.  The mechanic who is Kymcos dealer of the year in Sydney said that the tyres are extrememly hard to get in the size required.  I now have Front KENDA 48S 100/80-14 [China] and Rear SAVA MC38 MaxScoot 120/80-14 [Slovenia]  He did me a deal as I needed to get a seal in the rear replaced due to a leak so the tyres cost me F $80 & R $135 plus $55 fitting each. I guess I am a captured audience as no one else was interested in trying to source the tyre sizes I needed and I rang 4 other places in the Sydney area.]

     

    Good luck

    Hi Jeff,

    I managed to find the Kenda tyre in the correct size but only from BikeBiz in sydney  - they were very helpful and shipped itdown to Melbourne for only $10.

    Still waiting to hear back from the importer after 4 phone calls - something tells me they arent getting back to me!

    Unfortunately, after having it fitted, the speedo was way off - indicated 38kmh was 50kmh, 44 was 60kmh! apparently it was a 'coincidence' that one of the 4 magnet sensors failed at the same time as the tyre was replaced.........mmmmmm.........$75 later its been fixed.........

     

    cheers
