Re: good and bad day for tires
I agree with you, I would never ride on a patched tire. I have yet to find a Z rated patch/plug or any other repair method. Keep in mind that you are dealing with radials, so you have not only a compromise in the integrity of the sealing capabilities, but you have also compromised the integrity of the belt. if the belt did not need to have material in that spot, it would not be there.
Then you need to consider the expansion/contraction qualities of the repair material versus the tire. Will a heat cycle for the tire have the same effect on the material it was repaired with? I am not a rubber engineer of any sort, but I would bet not. I am wiiling to put a lot of trust in the engineers and developers of the Pilot Sports, but my life is worth more to me than the price of a brand new tire.
Go ahead and feel good about replacing that tire and doing the right thing for yourself, your loved ones, and your bike.
Once you are done with it, post the old one with a repair done to it, with no warranty, on www.sportbikes.net or on www.stuntlife.com for some stunter to buy for 25-50 bucks. (the going rate) These guiys are always looking for good burnout tires/cheap 'stunnin' tires'.
