Thinking about a wider rear tire

[Offroad]

Don't get me wrong I DO love the look of a big fat rear tire....I was in love with the 2014 CB1000R for that reason among others, but it just didn't fit my body.

One thing I thought I'd point out, I had a physics professor point out one time....if the reason for a big tire is added is for friction, that's a false assumption, because surface area doesn't actually exist in the physics formula for friction.

However, from what I remember, the reason wider tires are more successful at providing more friction than narrow tires is because wider tires can dissipate heat better. A little skinny tire on a funny car dragster tire would just melt immediately and lose all friction. Wider tires can absorb and dissipate that heat and remain intact.

If that is true and we aren't out there power sliding our CB's around curves, I'm not sure wider tires would actually help much.

I know there are a lot of educated people on here so if anyone can clarify, correct or enlightening me on this I'd be glad to correct my remembered conclusions on this subject I've carried around for years ;-)
