I think I would brush up on my physics before dispelling Capri racers info , there is plenty of science involved in tire technology and I think that there is more to rolling resistance than just width or lack there of.
At the other end of the spectrum , when I was a young lad getting into auto performance , someone with more expierience than me suggested to me that you would get MORE traction by running a skinnier rear tire than the fatties I was looking for , his theory was that given the weight of the car , and less sq inches of foot print you would achieve *greater* pounds per square inch , sounds logical , if you only look at a single variable , but after doing more research I found that there is more to traction than just psi , there is different rubber compounds , coefeicents of friction , temperature and the ability for the rubber to interlock with the pores and imperfections of the asphalt or concrete ,hence why wider softer tires create more grip . I am no engineer but I am open to the Idea that wider does not nessacarily translate into more RR , if you optimize other factors .
