manual recommends it i think before storage. Also, i heard that commuters and tourers run high psi but less traction while less pressure, more traction? I have a 06 Ninja 250r.
Get yourself a tire pressure gauge to be sure, then let out the prescribed amount of air. Guess work never works.
As others have said, running a car tire on a motorcycle is a really bad idea. The construction is very different because the forces exerted by a motorcycle are totally different than the forces a car demands. I have heard people say things like, it's just a cruiser - i'm not dragging my knee around corners. Okay, but you're still leaning the bike at anything over parking-lot speeds. That's a force that the car tire is not meant to cope with. I have heard, my friend did it for 60,000 miles, and it was fine. Your friend got lucky. Motorcycles rely on 2 tires to provide traction. If 1 fails, you're in a LOT more trouble than if 1 fails on a car. Why risk your life to save a few dollars? a decent set of motorcycle tires is under $200. How much is it going to cost to repair you and your bike if the car tire fails?
1) Why would you want to? 2) You can do anything if you're willing to cut and weld enough, or throw enough money at it.
Yes store the bike at 28 Front 32 Rear if possible with the tyres off the ground.(On a bike stand) tyres may get flat spots if the bike sits for a long time recommended tyre pressures are a guide depending on your riding style, you may need to vary these to suit your style. but unless your on the edge of traction your not going to notice a great deal of difference in tyre pressure changes I tend to run the rear a bit harder the front a bit softer on my Ducati But I tend to push front ends so feel happier with a bit more grip at the front
