18 Fat Rear Tyres: Need Vs. Want

Do we really need fatter/wider rear tyres..?? or do we just want it..??

Correct me if I am wrong but it seems like Indian bikers/consumers seem to prefer a bigger/wider rear tyre on their bikes.

One doesn’t have to look beyond the modifications that guys/"desi" bikers carry out on their bikes. Fitting a loud exhaust and a wider rear tyre always happens to be among the favourite ones.


Actually fitting too wide a rear tyre also has the following negative implications.

  • Decrease the performance and fuel efficiency of the bike by increasing the "Rolling Resistance" and adding additional weight.


  • It can also adversely affect the handling of the bike.


"Give bikers what they WANT and they would move Heaven and Earth to get it."

Even if "Average Kya hai..??" (What's the average mileage..??) still happens to be the national anthem among "desi" bikers, surprisingly they also seem to prefer a wider rear tyre. So why do we seem to prefer a wider rear tyre..??


Reason #1: Aesthetics

Most of us who have seen a Super Bike are always in awe of the impossibly wide rear tyre that those exotic bikes possess. Who wouldn’t like to dream of riding a similar machine someday? So while we work towards that transition, we may want to ride something which shows off to the world that we are indeed riding something powerful (Whether what they ride is really powerful or not is a different matter altogether).


Reason #2: Safety

Normally a wider tyre at the rear gives the feeling that while taking sharp turns and while braking, such a tyre would provide with more contact patch and therefore would be a safer one as well.

But the other day a particular guy put forward his point of view on this..


    "Most of the braking load is on the front tire and thats as thick as it needs to be. Shall i say it again, already tested and proven on the race track. You dont brake or corner half as much as that on the street".


Actually is it true. About 70-80 % of the braking in a motorcycle takes place on the front wheels. That’s exactly the reason why the front brakes are made more powerful on motorcycles.


Ok I understand.. But I would still say that a wider rear tyre is a "Psychological" need and maybe an "Emotional" need as well.




In the end it all boils down to what Bikers "Need" and what they actually "Want".. and I can safely tell you that "Give bikers what they WANT and they would move Heaven and Earth to get it."

Come to think of it, even Honda (HMSI) has to increase the size of the rear tyre of the New Unicorn from it earlier size 3.00 (inches) to size 100 (in mm).






Personal Experiences:

    It is not just the size that matters but also the compound of what it is made of:

    This is speaking from a personal experience of mine. I have a Yamaha RX100 (which my brother rides in Bangalore right now) and recently I went in for a rear tyre change. This time instead of going in for a tyre with fancy racing pattern, I went in for one with a simple pattern but which was made of "softer compound". The brand of this new tyre was "CEAT" and the tyre is called "SECURA".

    I went for this tyre on the recommendation of my mechanic and boy was I impressed with the tyre..!! Although the "CEAT SECURA" did not have any fancy patterns, the grip from that tyre was very impressive.



    Fitting an Wider aftermarket rear tyre:

    This is speaking from my brother’s experience. My brother used to ride a Hero Honda CBZ (Original) back in Assam. After a few years he decided to replace the stock 100 section rear tyre with a 120 section tyre.. the bike did look cool from behind but according to his own words, the handling all went for a toss.

    So the learning point here is that its better to stick to the stock tyre size. Going up one size (2.75 to 3.00 or 100 to 110) is should be ok, but going up more than one size would do more harm than good.

You have a reall valid point dude, but I really do feel that a factory fitted tyre, a wide tyre as per the might of the bike, is very necessary in order to keep the bike of the ground. For example the width of the tyre that we have in our P220 and P200 plays a very important role in the overall stability of the bike, because even though the majority braking happens at the front wheel, but the actual throttle is comming from the rear tyre because it's the spin of the rear tyre that pushes the machine forward. Therefore bigger and faster machines should always come with wider tyres as per the specifications of the bike!!!

What say?

GAGAN said...

i agree with the point of compound and texture. the compound factor actually pops up when we have air temperature almost touching 40 C...and that can actually mean ground temperature upto 60C or even more...an erratic compound actually falls apart in that heat..rubber goes softer and punctures become easy and more frequent. SECURA is a good one....plus it has that anti skid point added. Tried one more thing sometime back,lowered the air pressure by 3-4 points on the front wheel and the control and breaking became better but again its a very costly tradeoff with mileage. :))

Whatever Dudes.. "The Wider, the Better for me"

GAGAN said...

hehe...u bet!!

Sajal Chakraborty said...

Payeng Dude!!!

One more thing, a wider rear tyre also gives you more confidence when you are making those tight turns and you know the tarmac under your machine has lots of pebbels..........

Heehehe........ why do I feel I'm over cautious about things!!!

I concur...more grip(by reducing air pressure) >>means..less mileage(marginal) and less acceleration(marginal)...

I own a yamaha gladiator ss with mrf zapper tyres 2.75 and 3.00 at the rear factory fitted ... i am planning to have a wider tyre please anyone help me to choose the right size

Wider tyre is more even 'radius' over the shorter contact patch,less tyre deformation,lower deformation component to the coefficient of friction.

i m interested in buying a honda cb twister.
as we all know that the tyres in this bike r thin which is one of the disadvantages for this bike.i wanted to know that is it possible to ask the company to deliver the bike with thickker tyres if possible.
someone pls let me know asp.
thank you

shyam

@above,

as mentioned earlier, it's best to stick with the Original Equipment specs.. you can try mailing to the company letting them know what you would ideally like

Used Tires said...

Possibly! Front Tires needed to be strong in terms of Rear

I have a pulsar 180 UG4 with 120/80 R17 rear tyre. It looks really cool, and i must say that wider rear tyres are really great while taking tight turns in oblique position. They provide better grip over good and bad surfaces, but i must say that the tyre tread design also plays a big role in grip and traction, and MRF Zappers are the best in this regard..!

however i am planning to get a 130/80 R17 MRF Zapper rear tyre, for the same reason: looks and grip..

I think mileage will not be a problem,
*riding with a pillion and with stock tyres will definitely not give more mileage as compared to riding alone with little wider tyres, If weight is really an issue...
:)

Great Information.. Very informative...

Nithesh said...

Actually the fatter the rear wheal the more traction you get from the bike. It does help to keep ur bike planted on the road at all times!
