Rear tire #3

[NancysToy]

So the absence of enough weight could cause the tire to have a tendency to be running more on-center than evenly flat?

If you mean weight on the Spyder, possibly, but that is where the tire design, proper rim width, and proper pressure take over. Supposedly the tire manufacturer took this into account. In addition, any road design has a tendency to operate well over a wider range of conditions, than say a racing tire. My belief is that like gas mileage, there are differences from machine to machine (or tire to tire). I still believe pressure has the most influence on how a tire wears on a passenger vehicle, but other factors can influence it, even the type of road paving in your area and the specification of the asphalt.

REAR TIRES

I am by no means an expert on tires and I won't pick up my SO's new SE5 :yes:until the middle of the week but... there is always a but... from my weeks of researching, 4 to be a straight arrow, and 48 years of riding from 2 to 18 wheels it looks to me like there is a round shoulder tire where there should be a speed rated Michelin mxv4. Also centrifugal force also determines where the tire will ware. If the tire is soft when at speed it will bulge out in the center of the thread similar to when over inflated. The air we breathe is 78to 80 percent nitrogen. Nitrogen is a larger molecule and doesn't get through the microscopic holes in a tube or the tire casing. Air, oxygen, is a much smaller molecule which can squeeze through these invisible holes. I believe the key is you are using dry nitrogen which eliminates any moisture or oxygen molecules. Hope this helps. Science is great unfortunately I really didn't understand a lot of it until my mid sixties. To bad for me in my opinion.

I am a novice on the 3 wheels but it's an observation I have made. Some one please give me advice on this area so when it is time to get a new one I go in the correct direction.:dontknow:
