Can I mix a PR3 tire with a PR4 tire?
« on: March 23, 2014, 11:07:38 PM »
I want to get a new PR4 to replace my rear bald pr3. My PR3 front looks like it still has a lot of life on it. Is it safe?

No.  Send it to me before you suffer a catastrophic tire mismatch.


Seriously though, it's fine.  I generally ran through 2 rears per front before switching to the GT-spec Bridgestones.  Rears still wear out faster than the front, but not twice as fast like they used to.

Neither you or your bike will know the difference.  The front and rear almost always wear at different rates.  I have always changed mine (riding motorcycles for 57 years) when they were worn out.  On my C14 there is currently a Dunlop on the rear and a Continental on the front, my other bikes also have mismatched tires purchased at different times with price the deciding factor when choosing between tires of equal abilities.

There was recently a thread containing the same topic (although it is not in the topic name)

It is perfectly safe.

023 GT.  Running a 180/55 rear, turns in nicely, is lighter, and was available in GT-spec when I last installed new rubber.  Looking around, I see that a 190/55 rear is available in the GT tire now... might try that next go around.  They stick nicely all the way to the edges, and does 2-up just fine.  I run my rear tire at 43-44 psi cold, and it's great.  Of course after my first sportbike experience on Dunlop D204's, pretty much anything is light-years ahead.  I ran 003 RSs on my race bike, and have BT-016s on my Ninja 250.  Ran Pilot Powers on the Superhawk (the race bike) before the 003's, and based on those I'd be completely confident in a set of PR4s.  There are simply a LOT of good choices for tires these days.
