Tire pressure ? 5 Years, 4 Months ago  
I know everyone has an opinion ref tire pressure. So what seems to be best in general for my Roadstar ? I have Dunlaps D404s and should I run the max on the sidewall ( 41 psi )for handling which some say also prevents cupping or should I follow the specs on the mfg plate which is the same in the manual BUT no one seems to follow.

Re:Tire pressure ? 5 Years, 4 Months ago  
You'll find lots of posts about this elproadie. I follow the recommendations on the tire. If you're not too heavy, relatively speaking, you can inflate them just a tad under the max load. If you're heavy, or riding 2-up, then you might want to go to max load. I'm just over 270 at 6'2" and ride max load for air. I'm running the original Bridgestones at 36 psi front and 41 psi rear. Seems to work fine for me. You'll get other opinions for sure.

I think as long as your between what the book says and what the tire says your ok . ButI like to stay at the high end. Keep in mind that the cheap pressure gauges that we all use are not all that accurate.I think of my gauge more for consistancy in keeping the same pressure and it's a digital gauge. If you use a slide type gauge it's accuracy depends on a little spring and trying to decide what mark it's on.
Just check often

Re:Tire pressure ? 5 Years, 4 Months ago  
Thanks ...........I'm 5-11 and at 215 lbs so I'm running 38 psi up front and 40 psi in the rear and we'll see how she feels. I have a daily run to work down I-10 at speeds of 65-70 in traffic for about 47 miles round trip so that should give me a good feel and go from there.
Thanks again !

Re:Tire pressure ? 5 Years, 4 Months ago  
yah, welcome to the R* clinic. free shots of penecillin to every 3rd customer.

little squirrely mine was today but it's hotter than it has been latley and i assume it's tp.
so i'll go check. i'm runnin dunlop 402's and well by the rest of those who say tire wear stuff, it seems to me i'm gettin the best wear with 20KMi on the rear and hopefully i'll get that on the front too.
i run tubless and @ the settings on the label under the seat.

tire sidewall script is the maximum pressure at the maximum rated load for that tire.
you can run ANY tire that fits on the stock wheel's at the factory recomended spec (which you should) and compensate for any extra load by upping the pressure slightly.

as a scientist, i would say an average load ought to be 200# and i think the bike's like 1150Lbs GVW
an mine's about 800 and my fat ass weights in at 192, so for every additional 20# i'll ad 1 to the rear
ofcourse this means any girlies i carry cant be heavier than 120# (an if she is she better be taller than me)!

oh and BTW, were havin a sale on tire gauge calibration all next week, so hurry up an schedual yours before theyre all gone......

Re:Tire pressure ? 5 Years, 4 Months ago  
ok so i just cold measured, got 32 front and 34 rear and it's about 79*F
that explains why she was squirrely at ~85mph thisafternoon.

set front & R to 36 just now and took her for a blast around the block.
85-90mph without so much as a shimmy.

mind you i'm running the bias ply tubless, and they dont expand like a radial does
it just is what it is. atleast they are the WWW ones that look better.

and the seat says, 36/36 or loaded 36/41 (F&R respectively),
so if you are, find, or are expecting to pickup a heffer .......

Ditto on the inaccurate cheap gauges. I had 3 different pocket gauges and they all read differently; 10lbs between lowest and highest. My recommendation on tire pressure? Spend the bucks and get a good gauge so you'll KNOW what the pressure is.

Thats for sure!! I ruined a front tire real quick before I figured that out........
