not disagreeing with you. More to do with a discussion i have had on the Honda forum. Could not get them to see the logic of what Honda Recommends for tire pressure. Both my current CBR500 and former NC750S said 42r/36f - passenger or not. Also that pressure is max rated printed on sidewall.jon, just a point you may or may not know. The tyre pressures you are using are way too high. 36psi in the rear is for pillion carrying only. Front tyre pressure always stays the same at 25psi with or without a passenger. IF you are a very big guy, then by all mean go up just a tad but going so high (36) will wear your tyres very quickly and make the bike less comfortable and less stable with less grip in the wet.
The maximum pressrure printed on the tire is the absolute maximum safe cold pressure the tire should ever have--under any circumstances. Beyond that misunderstanding you are confusing automobile and motorcycle recommeneded pressures.Quantum Mechanic, I have always set my tire pressure at or just below max cold rating on the tires of every vehicle i have driven. I haven't known about manufacture recommended tire pressure until it was mentioned here. But after doing some browsing it seems that there are varying opinions/experiences among people who have or have not followed the recommended pressure. Here's how i understand it from my quick search.
Pros: optimum contact patch, optimum comfort, little better feel with front tire at recommended.
Cons: faster tire wear, little lower mpg, little more drag.
Pros: little higher mpg, slower tire wear (especially in rear), little less drag, quicker handling(?)
Cons: less contact patch, twitchy/slick in wet conditions.
I'm guessing the tire wear is improved because more of the riding is being done on the harder center rubber.
Am i missing anything?
