Thanks for all your help guys...
The e-mail from Kenda>>>>
Hi Ard,
Below is the response I rec'd from R&D:
If he is worried about damaging his drive train, I would say the difference in the heights front to back should have no effect on that. We have run tires with this much height difference before and have had no problems.
Have a good day,

Laure,
I did measure tires and in the attachements there are some pictures off how I did it.
The fronttire is at 6psi and measures 63.5cm, 25inch
The reartire is at 5psi and measures 65.5cm, 25,8inch
I'm know expert on this, I'm just worried to damage my drivetrain, so please tell me if this ok.
Kind regards,
Ard

Mr. van den Berg,
The actual specs on the tire are 25.5 inch diameter for the 27x10-12,
and 25.8 inch diameter for the 27x12-12, so although they are an
undersized tire, they should be almost identical in height. If you are
experiencing a large difference in the two tires, one set me be
undersized/oversized. What psi are you running the tire at? Also, can
you tell me the diameter measurement of your front and rear tires.
Once I hear back from you, I'll send this information to R&D and see if
I can get you a more detailed answer. If there is a problem with the
tire(s) being over/under sized, we may be able to warranty them for you.
Have a good day,
Laura

Dear Kenda,
I just purchaced a new set of tires for my Yamaha Grizzly 2004.
I choose the Kenda bearclaw K299 with 27-10-12 on the front and 27-12-12
on the back.
Now I noticed that the backtire has a bigger diameter than the fronttire
so the fronttire is spining faster than the back and causing stress to
the drivetrain. How can it be that the tire size differs if their both
27?
regards,
Ard van den Berg
