The general consensus here has been 30 psi.

But I've found I'm wearing the center too quickly on the rear and am now trying 27psi. No difference in ride or handling, too early to tell about wear.

I'm running Shinko and they're oversized.

Pretty sure the sticker calls for about 29/29, close to that.

I believe the Metzler site listed recommended tire pressure for those tires as 38psi front, and 42psi rear.....

If I can find the thread on this I will post it up....

Edit....only found their guide. The figures I gave were from past members...Metzlers own chart lists for the VN750 36 front, 40 rear:

Keep in mind their listing is for "minimum tire pressure" , so that 38/42 might be the way to go if you are heavy or riding two up.

Edit 2....found one of the more entertaining threads on this:

I'm going to openly admit my ignorance (stupidity?) up front.

When I got my new tires (Metzler 880) it didn't occur to me that the pressure would be different that what the VN750 manual suggests. I've been keeping them at the pressures stated on the sticker on the bike.

Time to up them to 38/42 I guess.

glad this thread was posted.

Not stupid...just uninformed... Am sure you're not alone.

But it is wise when buying any tire to check with the tire maker and see if they have a recommendation on pressure for your particular model. Not all makers list this of course, many, like Shinko, seem deliberately vague...

I doubt you did any damage by running that lower pressure, you may have accelerated wear, but it's not like these bikes eat tires. It's not uncommon for sportbikes to go through a tire in under 5,000 miles. Most cruisers are fairly kind on tires...and on tire pressures.

Heat is the biggest issue, and most tire pressure recommendations are based on finding a tire pressure that nets the lowest rise in tire tempature. You can get one of those laser tempature readers and do your own testing to find out the optimum pressure for your own tires too....

But how the heck am I supposed to measure tire temps while traveling at 65mph

Hahahahaha

DISCLAIMER: This post is meant to be sarcastic and is in no way to be used as instructions or as a means to measure actual tire temperatures. The correct method would be to drive the motorcycle and come to a complete stop. Rest the cycle on the kickstand/center stand. Dismount and then measure tire temperatures.

you need to get on 341 when the traffic is not there and get your wife to point a laser temp gun at your tires as she rides along beside you. Viola you temp

Grace and Peace to you!

Wrong....you have to stop the bike and take a reading at the center of the tire. You won't get a proper reading if the the bike is moving as its surface is being cooled by the moving air.

Yes, I realize you were joking ...but there are folks stupid enough to try pointing the laser thermometer at their tire while riding....

Good point. Now you got me thinking I should delete that post in the interest of safety. I'll just put a disclaimer.
