EricV I would be interested to know what pressure you run the Motoz on your S10 please.
I have experienced a few rear lockups since install. Distinguishing feature is all occasions on tar with a day above 22 degrees C which is not at all hot for down here.
I suspect I may be a tad high in the tyre pressure.
I liked 38F/42R psi for fully loaded tar riding. Dropping 10-12 psi for dirt/trail riding. Usually not dropping pressures for gravel roads. Temps in the desert ran from 20C to 45C+ for my riding conditions. Note that MotoZ marks their tires differently, the sidewall marking is not max pressure like other tires, but the pressure used for testing. It's not the max pressure for the tire.
@RoadWraith - I'm not Keith, but for the IBR I ran Heidenau K60 Scouts and did a rear tire change at checkpoint 2. I actually had the take off rear shipped back home and wore it out later. I could have finished the rally on one set of tires, but did not want to ride the last 10% of the rally on the last 10% of my rear tire. Considering the high winds and torrential rain on the last day with a hard push against the clock, that was a sound move on my part. I would not have wanted to ride that last night in the rain on a nearly worn out rear tire.
Generally speaking, the staff recommended shop is worthless. (every year is different) In '13 they were unwilling to be available off the clock for riders and asked us to make reservations for service times that would have been on the clock. I found a small Indi shop and shipped my tire and some other supplies there well in advance. That shop serviced many bikes and worked late into the night on a Sunday, thrilled to be making good money. Regardless of which checkpoint you decide to do a tire change at, find a shop willing to be available off the clock for your needs.
FWIW, I shipped my tire in a box, tossed in some socks and other supplies I would need, AND a return UPS label for the tire/box weight. I made a point of telling the shop to keep the box, as I'd be re-using it to ship the take off tire home. Worst case, if the tire was shot, I'd grab the label and get it refunded after the rally. That worked well for that time. Another time the shop tossed the box and I ended up paying some extra to ship the bare tire, IIRC.
