Anybody able to take accurate measures of a tyre ?

[HornetMaX]

Hi all,

I'd need somebody with track tyres (front and rear, rear more important): if you have motogp ones at hand, that would be great, but I can settle for SBK ones (or for whatever you have).

Would it be possible to give me:

• The tyre basic data (brand an name, plus ususal measures like 180/55 ZR17).
• Some of the measures in the below drawing:
  
  
  • The total tyre diameter (taken from the middle of the tyre, i.e. the biggest diameter): the 650mm in the pic
  • The tyre width (taken where the tyre shoulders connects with the part of the tyre supposed to make contact with the trackl) = the 225.17mm in the pic
  • The height of the profile = the 65mm in the pic

Ideally, the measures should be taken with the tyre not loaded (e.g. in its axle, not touching the ground) and as accurate as you can (let's say down to 1mm, especially for the width and profile height (225mm and 65mm in the pic).

It's just a curiosity so don't waste an afternoon to do that.

Yeah, that would be good. Assuming they are for your 675, I'd like to get some rear for bigger bikes (190 or more size), but the front is probably the same.
And right, let me know if they are new or worn.

Ah. They're 120 17 55 and 160 17 55...

The triumphs got Pirelli Rosso 2 (120 17 .. and 180 17 ..)

I will be getting some Dunlops for the triumph in the near future or supercorsers (price dependant )

[matty0l215]

 Dads 1199 has got supercoarses but there half worn so they might be no good to you.

Here you go

They are 200's btw, il pick out the best set over weekend and measure up.. But! They are loose not on rims. That ok?

Edit: il measure my mates instead, he runs them on the zx7r.. Already on bike.


Are you building a bike MaX??

[HornetMaX]

Thanks Matty !

@BOB: hmm I'd say on rim is better (as they are inflated).  If you measure the ones on the bike, let the wheel unloaded (i.e. not touching the ground).

I've found a drawing from a Dunlop Sportmax Q2:



Then I've layered on top of the red line a circular profile, as GPB does it (or at least as i think it does it). Black is dunlop, green is GPB:



Looks like a pretty big difference. Too big ?
