    So this means that we cannot conclude just on basis of the central groove.
    Now, in case it is not mentioned, how do we figure out whether a tyre is made for front or rear usage?
    For example, if we end up using say a 100/90/18" tyre for our bike's rear, which is actually a front tyre for a bigger bike, would it not give any problems?
    A Front only tyre will have "F" mentioned on sidewall. Eg. 100/90 18 SIRAC F. Otherwise technically the tyre can be used at the rear and front both. A tyre which can be put for front and rear will always have opposite side arrows stating front and back on the sidewall. This shows direction of rotation when fitted as front and when fitted as rear. A Rear only tyre does not have two directions of rotation on sidewall and does not have any other special marking on sidewall indicating it is arear only tyre.

      Thanks for the explanation. So in case of the M45 that I got recently, which side should I check to confirm?

          • RX 100 Tyres

            Guys

            Planning to change tyres for my RX 100, need your suggestion on which to go about...searched on the net and narrowed down to

            Front

            2.75X18 - MRF Zapper FS or Michelin M45

            Rear

            3.00X18 - MRF Zapper FC (Not sure about Moto C / Moto D) - If somebody can throw some light it would be great

            or Michelin M62

            This is only for my regular usage - No Racing ....though would require both wet & dry ride comfort and better cornering/grip

            Will fix disc for the front soon

            Pls suggest
            Never Give up on something that you can't go a day without thinking about.

              I saw pilot sporty@2200 at one place and liked it for rear. But now I saw some comment that its not good in gravels and got confused. Guys, is it worse than Zapper? For front tubeless (2.75/18)I am not getting options. Someone mentioned that Duro has that kinda tires..
              Guys please let me know if you have any other TL options for tubeless(Last one would be to convert M45 to TL).
              Also, please suggest it pilot sporty is good for Uni in my travel conditions.
              Thanks

              Guys, any comment please....

              • In my 13 years of experience with Rx, I'd say - STICK TO STOCK SIZE. I've tried all the fat tires, button tyres & what not & finally found nothing is as good as stock for 2 reasons...
                1. Engineering
                2. Life of tyres

                The stock size for front tyre is 2.50 X 18 & rear is 2.75 X 18

                Go for Michelin any day compared for MRF. But check which one has soft compound rubber. The ones with soft compound lasts very less but gives you best comfort than the hard compound rubbers.

                I'd used MRF zapper long time (read it 2000's) ago & again, over a period, the braking weren't that good because the area of contact with the ground was less. However, the turns were good ones. But the one I used to own had different tread pattern, so MAY BE, the ones now had been improved over time, not sure though.

                Just saw the pattern of it now, MRF had similar looking one long back & I'd used them. Frankly, nothing impressive on them. May be its due to MRF, not sure though.

                I'd still say STOCKS are best; I use CEAT these days which is bang VFM product & sizes as per manufacturer including the tread pattern. Yes, they're little bad when it rains or on slippery surface. But on try tarmac, they do an excellent job. Oh!!! the zapper does a good job too in rain.

                • Thanks Aargee....

                  are you sure it was 2.5*18 in the front and 2.75*18 in the rear...I saw somewhere the stock is 2.75 & 3.00 as stock. ok will go for the stock

                  Brand - Michelin
                  Size - Stock (2.5 & 2.75) - Michelin / MRF doesnt have 2.50 I believe hence for rear will go for michelin soft compound M62 & M45

                  Any other choice

                  DIY - Dint wannu risk on this safety parameter - Will have some expert work on it.

                  • @Ramesh: What Aargee suggested is the company recommended sizes. Using the stock size rear tyres have felt that good but 3.00 is better.
                    Here is my suggestion:
                    Front tire: 2.75 MRF Nylogrip
                    Rear: 3.00 Michelin Sirac Street

                    Sorry for deviating from the stock sizes. It is my personal experience that I strongly recommend you to go for 3.00 size for the rear. Shortly I'm planning to change the rear to Sirac Street.
                    RX100 1996 | Karizma 2004 | Karizma-R 2011 | RXZ 1999 | RX 135 1998 | RX 100 1993 | CBF150 2005 - 2011

                    2012 - Meghamalai | Kuttralam | 2011 Ooty | Munnar | 2010 Point Calimere | Horsley Hills | Yercaud

                      VERY MUCH sure for Rx. But, but...it was 2.75 in front & 3.0 for rear only for RXZ 5S.

                      CEAT; I switched to CEAT sometime during early 2008 on both front & rear. They're currently serving me OK for over 27K+ Kms. I'm sure they can last easily for another 3K Kms.

                      This WORKS no doubt, but the thing is that, there WILL be a slight drag. If you're willing to live with it, then its fine. Anything more than 3.0 in rear or 2.75 in the front is a KILL (or unnecessary) for sure.

                      What's Sirac Street

                      • i got the tires on my Fiero changed over the weekend from the factory fitted TVS tires to Michelin tube types.

                        I got the M35 for the front and Sirac Street for the rear. Both in stock sizes (front - 2.75x18 ; rear - 3.00x18). Now the bike does not tramline on bad roads and is very stable on straights.

                        I only have one doubt. The sirac on the rear has button type treads and is more rounded which makes my bike feel like its tipping over when i am negotiating a turn. Earlier the bike was running on factory fitted TVS tires which was more of a "flat" tire on the edges. I could corner harder and faster with more lean angle earlier, but now the bike feels more eager to lean and is not stable through the turn... maybe i just have to get used to it. It feels like its eager to lean and also turn and the bike feels unstable.

                        Any thoughts?

                          Good choice made!
                          Now for the rear, two things. Sirac Street has softer compound at the sides, which aid in cornering, so don't hesitate.
                          About the wiggly feel, two reasons:
                          1. The tyres are new-they need a few hundred kms.to set in.
                          2. You were running a larger size tyre previously, so you are used to a higher sidewall height.
                          I also felt exactly the same for the rear, but now am enjoying it. Both will improve with time. Just keep riding!

                          @aargee: That is the Sirac tyre, this is the Sirac Street.

                              Thanks a ton for your suggestion Sarvajit. I'm glad the tires were changed, both of them. The front also had to go without doubt as the rubber had cracks on the sides. Was thinking of selling off the bike and getting a new one but will keep it for some more time, hence the makeover.

                              I also felt that the grip levels would improve after the rubber wears in.

                                All you need to do is get the right parts that both Sri & myself already have bought . Remove the front suspension & it will be a direct fit. Very simple & should be a half day's work & will not exceed more than a day even if one runs to any problems.

                                OT - Ask Sri how issues can be fixed in 15 mins Lol!!!

                                Sirac looks tad heavy to me; as a stock lover, I'd stay away from it unless I need any beatings on the conrod!!!
