When do larger tires require larger brakes ?

[Front Runner]

For the record, (and I know weight/mass plays a role) I was mostly referring to the tire circumference ... A larger diameter tire has far more leverage to overcome ...

Mass is one aspect of this but an increase in tire diameter with the same diameter brake disk would make a large difference in stopping ability ... Better pads or more pistons in the caliper would help of course but larger disk would likely help the most ...

If anyone wants proof, look at the disk diameter on a sports car ... Some are close to the wheel size ... That larger brake disk stops far better than typical sized disks ... And a larger diameter would have the same effect (Only it would make stopping worse) ...

I was simply wondering what the collective experience has been in stopping with 35, 37, or 40 inch tires with no corresponding increase in disk or caliper size/capacity ..

Larger discs dissipate heat better also.

I’m trying to be funny, but probably came off being a dick. You can’t argue with the physics of it though (I guess you can, but you will be wrong). When a tire radius increases, your braking power decreases.

Fair enough, sorry for taking it the wrong way.

I think we may agree that the braking power changes. The more I looked at it today the more it seems like the stopping distance was less dependent on braking power and more about the tire friction.

All just curiosity, I can understand the math if I can find it written out somewhere. I'll take the word of everyone here saying they notice a difference
