@GoGreen Have some questions regarding new Michelin tyres
1.Are Michelin Sirac Street and Pilot Sporty Tube Type or Tubeless Type ?
2.What is the Michelin authorized price? Is there also a Pilot Sporty and Sirac for the front to match the rear?
3.What is the life of these tyres under mixed highway city and off road riding?

Irc tyre

This is the IRC tyre from my friend's ORKUT profile his name is SAHIN from team INSANE kerala.

Am not sure will this 130 will do good, moreover its a soft compound too. Heused to have his rear stock tyre on front and run.

I just rechecked the link which I had sent, it has separate images for the front and rear. The front has a distinct central groove so you wont have to worry about differentiating between a front & rear tyre. User reviews (though for bigger bikes using the same IRC model) seem to be good.

@ Sarvajit - Didnt know about fake IRCs. To my knowledge it is P220 owners who look at IRC as an option.

@ Dileep - Just saw the new pics. Is that a 130/70 or a 130/80? Whichever it is, the ride dynamics would have changed with a more forward leaning posture (i.e. lot of pressure on the wrists while braking). I met a guy in my office who had also moved his rear stock onto the front and used a larger MRF Zapper 17 inch at the rear. He changed to that from day 1.

OK is hey driving with the same set up till now. Am not very keen on interchanging. but planning to change it as a pair (front & back). And one more thing i also want the same handling as with the stock tyres. So only still thinking.

How about pirelli and michelin tyres?? i have no idea on these.

check the irc site they 80/90/17 and 100/80/17 for honda cbr125 same as r15 but i dont know its available in india the product code is nr-73

^^ Thats the front tyre.

@ Dileep - Check my post on this thread for michelin & pirelli details.

This looks very similar to the MRF stock tyre!
Will update this in the R15 thread too, thanks.

Hey dude the pic stated a front tyre but the sizes mention on the IRC site is for the REAR one. Just chk it out if i am wrong.

Any ways there are certain sizes which are not mentioned not sure either will keep it updated.

Will do that Neil

[QUOTE=dileep.anirudh;565466]Hey dude the pic stated a front tyre but the sizes mention on the IRC site is for the REAR one. Just chk it out if i am wrong.

ya you are true but site mentioning that pics for both tyers

i want a good tyre for my pulsar 150 front......it should provide excellent grip in dry as well as wet conditions...100% on road use...soft compound preferred.......can anyone suggest it.

can i get R15 front tyres....they must be available in market....i mean if r15 tyres need replacement....where does teh r15 owner get those sticky tyres..??

Very difficult to read the numbers listed one below the other. Is it possible to post this in tabular form?

Prajwal

While in this thread, a lot has has been discussed about tyres....the basics are still missing, so i thought its time to provide some basic info..

Deciphering a Tire Size

Motorcycle and dirt bike tire sizes can be expressed in 3 basic formats: Alphabetical, Metric and Inch. Each format tells you the tire and rim size.

Alphabetical Size Format

The alphabetical size format is mostly used on older bikes. Some current touring bikes still use the alpha size system. Most tire manufacturers use the metric tire size designations now. The size we will use in our example is MU90-16 B.

M====Motorcycle Code
U====Tyre Width Code
90===Aspect Ratio
16===Rim Size or Diameter
B====Load Range

The Motorcycle Code means exactly what it says. Tires made specifically for motorcycles are coded with an M.
The tire Width Code is just a letter to substitute for the width of the rim. The width codes below are for motorcycle tires with an aspect ratio of 80 or greater. A code of U means this tire will fit on a rim that is between 2.75 and 3.50 inches wide. Please note that the values in this chart are the RIM width not the Tire width.

Width Code-------Rim Size Range in inches
G ----------------> 1.60 - 1.85
H ----------------> 1.60 - 1.85
J ----------------> 1.85 - 2.15
L ----------------> 1.85 - 2.15
M ----------------> 2.15 - 2.50
N ----------------> 2.15 - 2.75
P ----------------> 2.15 - 2.75
R ----------------> 2.15 - 2.75
S ----------------> 2.15 - 2.75
T ----------------> 2.50 - 3.00
U ----------------> 2.75 - 3.50
V ----------------> 3.50 - 4.00

The Aspect Ratio is the tire section height divided by the section width (not tread width), multiplied by 100. The section height is measured at the center of the tire crown. The tread width is usually greater than the section width. The section width is measured from the middle side walls (above the bead, below the tread). It is multiplied by 100 to give you a whole number for the tire. So instead of .9 the tire is stamped 90.
Rim Size or Diameter is the outside diameter of the rim, also called the wheel size.
I have so far been unable to find a complete description and value set to explain the Load Range. When I find an adequate explanation, I will put it here.

Metric Size Format

The vast majority of tires manufactured and sold today come with metric sizing. The tire size we will use for our example isa 120/70ZR-17TL. It can also be written as 120/70Zx17TL or 120/70ZR17TL.
Some manufacturers put the speed rating at the end of the size and do not indicate if the tire is tubeless or not. In that case the size would look like this 120/70-17Z.

120 / 70 Z R - 17 TL

120====Section Width (MM)
70=====Aspect Ratio (%)
Z======Speed Rating
R======Tyre Type
17=====Rim Size or Diameter
TL=====Tubeless

The Section Width is the width of the tire measured from the middle of the side walls (above the bead, below the tread).
The aspect ratio is the same as for alphabetical sizes and is defined above.
The Speed Rating is explained in detail below. For our example a speed rating of Z means this tire is rated for speeds exceeding 149mph.
The Tire Type can be either B for bias or R for radial. Most newer bikes use radial tires. Bias are still available for older bikes if you are going for authenticity.
Rim Size or Diameter is the outside diameter of the rim.
TL is a descriptive abbreviation. It indicates that the tire is meant for a tubeless application. The majority of modern motorcycles use tubeless tires. If your bike has wire spoke wheels you need to use a tire designed for use with a tube inside. All those spokes and nipples are not air tight. Not all manufacturers will add the TL to indicate that it is tubeless. It was used more when they were not as common as today.

Inch Size Format

The majority of modern motorcycles and dirt bikes do not use these tires. These were standard equipment on older machines. The Inch or Standard Inch Size Format does not include an aspect ratio. The aspect ratio on these tires is 100. Meaning the section width and section height are equal.
Also, inch size format tires are all bias type. They do not come in radial. The size we will use for this example is 4.60x17H 4PR. You may also see this written as 4.60H-17 4PR.

4.60 x 17 H 4PR

4.6====Section Width (Inches)
17=====Rim Size or Diameter
H======Speed Rating
4PR====Ply Rating or Bias Casing Strength

The section width and rim size are defined in the same manner as described for the Alpha and Metric size formats.
The speed rating is explained in detail below, but in our example, a speed rating of H means this tire is rated for speeds not to exceed 130mph or 210kph.
The Ply Rating is a descriptive abbreviation. It refers to the number of plys (layers) that make up the tire. For more on descriptive abbreviations, see sections below. For specific strength of the different ply tires, refer the tire manufacturers literature.

Dirt Bike Tires

Dirt bike tires are sold in both metric and inch sizing format but do not always have a speed rating. More often they are rated by terrain.
Descriptive Abbreviations
Sometimes a catalog will list a tire as TL, BL or RWL. These have nothing to do with the size or handling. They are strictly descriptive. They describe the look or another feature of the tire.

Abbreviation--------------Meaning
B -----------------------> Belted
Blk ---------------------> Black
BW ----------------------> Black Wall
NWW ---------------------> Narrow White Wall
OWL ---------------------> Outlined White Letters
PR or Pr ----------------> Ply Rating
RBL ---------------------> Raised Black Letters
RWL ---------------------> Raised White Letters
SW ----------------------> Slim Whitewall
TL ----------------------> Tubeless
TT ----------------------> Tube-type Tire
WW ----------------------> White Wall
WWW ---------------------> Wide White Wall

Tire Load Index Ratings in Pounds

In addition to the information listed above, tires can contain Load Index or Rating info on the sidewall. This refers to how much weight a tire can safely transport. It includes the weight of the bike and rider(s). Not all tire manufacturers make tires in all load indices. Dunlop, for example, starts at 33.

Load Index Rating = Carrying Capacity in Pounds

Tyre Size Conversion

Tyre size conversion from metric to inche is very confusing and can not be done by simple conversion from MM to Inch. please use the table below to find out equivalent size. the major difference is that tyres with metric size are generally low profile tyres and Inch system was used earlier when tyres had square profile i.e. aspect ratio of 100%. Approximate equivalent tyre sizes are mentioned below


Motorcycle Tire Size Conversion Chart

Street Tire Sizes - Front

Alphabetical---Metric-----Std Inch
MH90-----------80/90------2.50/2.75
MJ90-----------90/90------2.75/3.00
MM90-----------100/90-----3.25/3.50
MN90-----------110/90-----3.75/4.00
MR90-----------120/90-----4.25/4.50
MT90-----------130/90-----5.00/5.10

Street Tire Sizes - Rear

Alphabetical---Metric-----Std Inch
MN90-----------110/90-----3.75/4.25
MP85-----------120/80-----4.50/4.75
MP85-----------120/90-----4.50/4.75
MT90-----------130/90-----5.00/5.10
MU90-----------140/90-----5.50/6.00
MV85-----------150/80-----6.00/6.25
MV85-----------150/90-----6.00/6.25

The above tire size conversion chart does not mean that these tires are universally interchangeable. They are to give you a point of reference when upgrading your older tires. Consult your motorcycle's manual or manufacturer's customer service department for correct replacements for original equipment tires.
Critical clearances, motorcycle compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations, and front-to-rear tire matching will all vary with tire selection.
Wrong selection can result in tire failure, loss of control with serious injury or death. You can also contact the manufacturer of the tires you want to put on your bike. They have reps dedicated to this stuff.
