Wow.... interesting discussion. Bottom line is that each rider has to come up with their own game plan. I am spent time corresponding with several previous IBR vets gathering a lot of valuable information. Based on feedback from various riders and knowledge of my own limitations (granted the longest rally I have participated on is the Iron Butt 5000 so I still have much to learn..) I have come up with a plan. Typical for me, I have a plan that includes contingencies and minimizes potential stress of worrying about a tire that may or may not go the distance or a tire that has limited life left at a point in the rally that I expect to be mentally and physically very tired.
Regardless of the view of others, I am comfortable with my current plan. I have learned that it is important to ride your own ride. When I do that, I usually do well and have a lot of fun. Do I expect to be in the top 10? Of course not. But I will be riding to best of my abilities and I do not want to have to "back-off" during the rally due to mechanical/tire concerns.
My current game plan includes another set of wheels. For those interested, below is my "tire plan" for the rally.
1) Install a new set of PR2s tires (my current preferred tire) on spare front and rear wheels. I will leave the wheels with the new tires at a friends or with family prior to leaving for the start of the IBR. Note that I live only about 4 hours from the checkpoint.
2) Leave for Seattle with an "older" set of tires to ride the ~2500 miles to the start of the IBR.
3) Ignacio, who lives a few hours from the start, has graciously agreed to let me use his place to install a new set of tires and complete an oil change prior to the start. I plan on installing ME880s which should "go the distance" of the IBR if required. I have never ridden on ME880s before, so I will be installing a set of ME880s to use for my first LD runs when the snow melts and my 3 practice rallies before the IBR. Plan A is to ride the entire IBR on the ME880s.
4) During the first leg, I will have a good idea on my route and where it will take me. I am hoping that it takes me close to my local trusted dealer (only a few hours from the checkpoint). If so, Plan B, is to have the replacement tires/wheels delivered to my dealer to have the new tires/wheels installed.
5) If my Leg 1 route does not take me close to my dealer, then Plan C is to have the replacement tires/wheels delivered to the Checkpoint hotel and to install the tires/wheels in the parking lot.
6) If Plan B and Plan C do not seem viable or I change my mind, I can always revert to Plan A.
7) Having an extra set of wheels/tires available, also gives my the added contingency of replacing a damaged wheel during Leg 2 of the rally. (Damage to a wheel on Leg 1 would probably result in a DNF).
8) My preference is to have fresh rubber installed for the start of Leg 2. This is the lowest stress option and the option with the highest probability of success from a tire perspective. This option also gives me the ability to ride the 2500 miles home.
So all that said..... the question still stands. Anyone have an 04ABS, 05ABS, 06 or 07 rear wheel?
