god has nothing to do with the sun,but if he did i would start to believe just before i die.because as i said,people fear death and made up the god thing.you used your supposed god to issue a threat of some sort to my existance this type of comment will have happened thousands of years ago to convert god fearing people to believe.

roger roger,you described the replacement of human organs and cancer cures as an act of god.surgeons replace the organs donated by generous people who want to help others.if all the donors believed in god why would they bother with having a belief that a better place is in heaven .sorry if this offends because i also believe that most.. god fearing people are a caring kind.

i used to work for a tyre company who made a tyre that had less rolling resistance.to prove this they got two identical cars and fitted there own to one and another manufactures tyre to the other.the cars were rolled down a ramp and one car rolled farther .of course some clever clog in the audience suggested that the cars maybe were not so identical.the same tyres were swapped over and the other car rolled the furthest.so i think the answer to you question is yes,a tyre can change the speed slightly because of the type of rubber and also tread pattern.
