Last semester we have learned about tyres, and tyre dimensions. And in theory it says, lower tyre profile and wider = lower rolling resistance, higher tyre profile = higher rolling resistance.
Here is a picture of the difference betwen high profile, and low profile tyres
As you can see the the wider and low profile tyres have less surface contact (I don't know hot so speel it right because my English is still not that good, and I know that now sounds like the wider tyres are less safer than thyn tyres, but I hope somebody will get my point
)
