As mentioned weigh...I'll add my two cents here. As mentioned weight is also a factor. If you are going to be riding two up with lots of stuff (face it if your riding two up number two SHOULD be a female and they always have to bring lots of stuff) Then max out the pressure. If you read your owners manual (yah I know how does that?) it will even state this.<br /><br />And Mr. Baron with all due respect you got the logic wrong. As you might know I work on Mercedes-Benz for a living. During service of these fine high performance machines I always check and set tire pressures. Each model has different settings. How do I remember all of these settings? I don't, I look in the gas door. Guess what? I quote, "for driving 100+ mph + 4PSI, for warm tires add + 4PSI." <br /><br />Here is why your logic is wrong. The extra pressure actually helps the tire hold it's shape and NOT expand as much as if it had lower pressure. Just as someone else said, lower tire pressure will also affect the contact patch of the tire, i.e. the shape. Now before you say "but drag slicks only have about 5 to 6PSI" remember this, these tires are designed to run at these pressures. Plus have you seen how that tire looks at speed? The back side (in direction of travel) is almost flat against the wheel and it has grown several inches in size. This is all the effect of low tire pressures. There is also this. Lower pressures cause higher tire temperatures too. Why? Friction. This why properly inflated tires give you better gas mileage, less friction. Less friction equals less heat. A under inflated tire will actually fail sooner (Ford Explore anyone?) then an over inflated tire because of high heat. Which all add up to long tire life. So in the end, for high speed riding, max it out.<br /><br />So after saying all of this can you guess where I run my tires? Yup, maxed out, 45 rear 42 front. For all of the reasons above but also because the bike does handle better and it does promote longer tire life. <br /><br />Last thing for you others who don't check your tires. For the love of God please do! Not only will it be safer for you but you will save money!<br /><br />fasthairfasthairhttps://www.blogger.com/profile/16578895011107651084noreply@blogger.comtag:blogger.com,1999:blog-6589437936874464039.post-84526196678506415142009-06-04T08:29:31.800-07:002009-06-04T08:29:31.800-07:00This comment has been removed by the author.fasthairhttps://www.blogger.com/profile/16578895011107651084noreply@blogger.comtag:blogger.com,1999:blog-6589437936874464039.post-7730489851782808152009-05-25T17:01:28.203-07:002009-05-25T17:01:28.203-07:00kathy: Wow!

Same speed same weather conditions.

It's amazing the difference a couple of pounds makes in handling. For the daily commute, I check the pressure once a week. For longer weekend rides, I check it before leaving. I have a small compressor powered by my car auxiliary port that comes in very handy for the job and I keep a tire gauge in my windshield pouch so I always know where it is.kathyhttp://www.chromeandpearls.comnoreply@blogger.comtag:blogger.com,1999:blog-6589437936874464039.post-21710395221284792562009-05-24T15:50:19.619-07:002009-05-24T15:50:19.619-07:00Baron: First, I would ask why you ride at higher p...Baron: First, I would ask why you ride at higher pressures if you think it will cause a blowout.

You deserve a good tongue-lashing;} Checking tire pressure is easier than paying hospital bills.<br /><br />Mastercheif: Do it today. Don’t wait till tomorrow tomorrow tomorrow… <br /><br />Big D: I hear ya, but I can’t say I’m shocked. I see low tires all the time. I’ll check my tires before I’ll check the oil. I can run just fine a little low on oil, but I can damn sure tell the difference between 5 PSI in the tires. Crashing sucks. Stupidity is avoidable. <br /><br />Ann: You “make” him check your tires? Or, could it be that he checks them because he feels that it is an honor to serve such a fine woman as you? ;)<br /><br />“D-Day”: A blowout at 65 in the rain? That had to suck. As far as your rubber goes, that’s none of my business :]<br /><br />Dave: That’s pretty good mileage. But I will caution you that dropping the pressure to low is baddd. It can cause the center of the tread to become concave and not contact the road at high speeds.Willy Dhttps://www.blogger.com/profile/13865633242705849475noreply@blogger.comtag:blogger.com,1999:blog-6589437936874464039.post-20975068464455029442009-05-21T17:57:15.368-07:002009-05-21T17:57:15.368-07:00My mechanic tells me 41 psi, so that's what I run ...My mechanic tells me 41 psi, so that's what I run with.
