    Tyres

    MODERATOR MESSAGE:Use this thread for any discussion related to tyres.
    To begin with, please dont curse me for starting this discussion and ask me to chk the prev posts. I did, and the information is all sketchy. So i m posting a new topic... Sorry abt that...

    I am thinking of fitting imported tyres onto my p180dtsi
    BUT I ABSOLUTELY AM AGAINST DOING ANY STRUCTURAL MODIFICATIONS TO THE BIKE, LIKE TO THE RIMS SWING ARM ETC.

    So plz tell me which is the max sized tyre I can fit, keeping the same rim on my p180dtsi, where can I do this (in mumbai), and the cost of the tyres.

    I read Hatari's discussion on how the engine is loaded when tire size is reduced.
    I dont wanna put any extra load on the engine whatsoever.
    Will my engine stay fine, as I am keeping the diameter constant (rim is the same) , or will it be loaded even because of a fatness increase. If this is so, I will drop the whole idea.

    What are the pros and cons of the following two types of tyres: those which have a "spiky" grip, like in dirtbikes and "bald" tyres like those in SBKs.

    Regarding the front tyre, I ofcourse am not gonna upsize it coz that will make handling heavier, but what abt same sized tyre with better grip?

    and lastly, just for information sake, I read on this site that if u fit a smaller tyre, u gotta do resprokecting to compensate for the loss of speed at a particular RPM, in order not to load the engine. so can anyone plz calculate and tell me, if somebody has fitted an elim rim on the rear, how many teeth should each of his sprokets have, in order that the engine is not loaded at all, and the speed at a given RPM does not decrease??? Thanxalot...

    Once again teh same Post with some additions:

    I) Dunlop Monster..(800/- INR in delhi) if you have a bit of offroad on your dailly commute way..then its good.. 100% tarmac.. waste..

    II) Geo Cruiser.. (800/- INR in delhi): The THE worst tyre... good for nothing.. the cheapest tyre..many people use it..but trust me its THE worst...

    III) Ceat: SECURA Zoom(1300/- INR in delhi): the only Dual purpose tyre..that motorcyles can bear wit...

    IV) Ceat: MOCROSS (1800/- INR in delhi): 100% OFF road tyre..useless for you..
    rest ceat.. no much idea..

    V) MRF Zapper Q..(12-1500/- INR in delhi): THE BEST FRO ZMA .. 120/80 section.. tubeless.. direct fit... no probs.. ultimate grip..even on water.. after Nylozapper FS and S,it is the tyre that gives the best water resource planning and awesome grip on water on tarmac..

    VI) Pireli.. (18-2000/- INR in delhi) :Way to costly.. and gives you awesome grip.. but not on water,also a bit of soft compound..so wear's Off fast..


    VII) Last but not the least.. there are a couple of more brands:

    RALCO(650/- INR in delhi): Useless,this company earlier manufactured tyre for rickshaw's and cycles..with the brand name of "RALSON"..
    Reason being: tryes very hard,and heavy,gives a lot of stress to the engine..god for person's who are learning wheeliee's ..

    METRO CONTINENTAL(800/- INR in delhi): IF you put up in chhera punji or myswarryam..then this tyre is THE BEST ..

    KINGS(1200/- INR in delhi):100% chineese tyres.. worthless.. waste of money...

    VEE RUBBER(17-1800/- INR in delhi):Very nice tyres.. awesome grip.. soft compound..provides a less grip when comes in contact with water + tarmac..
    rest in all fine..

    i dont think u will lose speed if you put a smaller tyre...there was a great article last year in some month issue of overdrive (i forget which 1)about the art of sprocketing....maybe u will find it now on its website.....

    here the mechs say (i dunno if its true) the max size u can put in a P-180 is 120/90 with the same rim (without increasing the rear shocks).....the BEST tyres available in the "bald" type here are of the DURO company...u'r mileage WILL decrease definitely- i dunno abt accl and top speed....the max size with the "spiky" type is 4.60.....
    i HAVE seen bikes here with those size tyres.....but most of them have raised their rear-shocks and cut-off their rear mudguards....

    i have no idea on the pros and cons....i just know wider tyre= better grip =better stability
    DoN\'t LivE tO DiE, dIe tO LiVe

      i dont know abt the max tyre size tht can be put on the stock rim of 180dtsi.

      i suggest you choose the normal tyres instead od bubble tyres(dirt bike).The bubble tyres spoil the looks.
      The speed and acceleration and mileage will be affectedd.
      yup the engine will be stressed, so u have to perform re-sprocketing, if the tyre size is reduced or increased.

      you can the put fatter tyres on front too,the handling will be heavier, but you can easily handle the bike...
      You will pay for your sins. If you have already paid, please disregard this message.

        tanmay.. dont change ure tyres just for the sake of changing tyres.
        There'l be new issues.. rpm, speed, handling, mileage etc to address
        the Zappers on the 180 are good enough.

        DO NOT PUT SLICKS ( bald tyres )
        they'r meant for racing.. and have NO GRIP in the wet.

        spiky tyres are meant for off road dirt/muddy conditions.. not for city riding
        ( there are no pros for this.. only cons )

        now for the sprocketing..
        this depends on the tyre ( if u change it ).. so there is no fixed formula..
        however, if u dont change the tyre, its simple

        when i changed my CBZ sprocket.. this is the article i referred to..
        just found the link... it has all u want to know about sprocketing !

          hi i won a pulsar180...the stock tyres are not upto the mark....on harsh brakin it slips(no skiddin-----only straight lines..)i fine cbz tyres better than stoc pulsar 180 tyres...coz they hav wet stability also...regardin to mods......very wide option is available......u can fit duro or maxxis tyres.....mileage change will be around -6/7 dot.......michelin tyres are gud.....the one on tendonwrencher p 180..........but elim tyres luks gud..............
          the affect ur top speed.......elim increases initiial...and decreases top end......u choose one which is suited for u..........
          and duro tyres are unidirectional with a straight cut----which gives wetgrip...not as stock p180....

                thx rash, so assuming I put 120/90-18 or 130/90-18 tyres on the rim, without any mods, do I load the engine or reduce fuel efficiency? and btw why is fuel efficiency reduced? is it because of the loading engine factor caused by smaller diameter tyres, or is it because, more surface area in contact with the ground, so more friction caused, so more mileage...

                  I was referring to a discussion "Pulsars Vs Fiero F2" in which there's an interesting debate on Radial tyres. Which of the tyres in the indian market, or the imported ones mentioned above in this forum Duro/Maxxim/Barracuda are radials?? if not are there any radials available here??

                      Tanmay,

                      theres some confusion.

                      hatari meant tht,
                      you should use the normal tyres, thts the grooved ones which we use normally.

                      He thought tht the bald tyres (as u mentioned) as the tryes used in SBK racing which have no grooves, so he advised you not to use those type of tyres.

                      hope you understood

                      You will pay for your sins. If you have already paid, please disregard this message.

                          Sorry for replying late dude...
                          well the average drop should not be much, around 5-6 kmpl. thats because of the bigger contact patch...so more friction and the other factor will be the weight of these tyres ( Barracuda ). Being tubeless they are heavier than the normal tyres...I suggest u go for the Michelin M45 4.00 inch tyres...they are made of soft tyre compund and are very light weight. I did not find ANY mileage drop on my Karizma when I changed my Zapper to the M45.
