As mentioned a lot of variables go into tire wear as do certain trade offs. The pressure stated on the tire is the max load the tire can take at its max pressure. The bike manufactures tire pressure is the recommended tire pressure for that specific bike based on what the manufacture considers would be an average load or weight place upon the tire. One can vary on the pressure based on what he is carrying. Constant highway driving and at what speeds or constant twisty's also effect how a tire wears. Measuring the tread depth across the face of the tire is the best way to judge if the pressure in your tire is right for your style of riding. For example if you do mostly highway riding and the tire shows more wear on the sides than in the middle you need to raise your tire pressure (NOTE too low pressure also causes more side wall flex creating more internal friction in the tire casing raising tire temperature and premature tire failure ). If the tire shows more wear in the middle than your pressure is too high for your situation. This also creates less contact area between tire and road surface. adding to excessive tie wear mostly down the middle of the tread. Another thing to consider is the fact that in most cases (and there are exceptions ) that tires that wear faster generally have better road grip due to softer compound versus tires that produce higher wear miles. I have run dunlop E3 and E4's through my last several tire changes and got amazing millage out of them. BUT I always ended up changing them before the tread were down to the wear indicators, because once they reached a certain point they became slippery in the corners. So if your doing a lot of twisty roads I would probably stick to the 777's But if your primarily doing straight highway driving specially two up and/or with extra payload I would recomend giving the E4's a try.

I got to talk with the boy this morning and he is 8 years old. Stopped to tell him that school had a two hour delay due to the cold. And talked with him about staying in the driveway and be seen when the truck or buss is coming. And he was a very nice about it, And he said that he would from now on. I am thinking he got a pretty good scare out of coming so close to getting hit. And he had on a new blue jacket instead of the black one he had on yesterday.

Add to all that, if you lower the pressure because you ride all highway you might find that very comfortable until you decide on a whim to do a twisty or two and find out that the rear gets squirrely,,, yep, now you have too low a pressure for that exercise.,,,, so somewhere in-between maybe??? always a bit of a guessing game.

Welcome aboard. I joined about 2 years ago. Good people here and a great knowledge base too.

LOL We are the only group that can secure our employment. If it ain't broke upgrade it.

I am surprised they even plowed in that fashion. Up here highway plows usually team plow, with three staggered trucks 1st plow does the third lane and a piece of the left shoulder as well as part of the middle lane, depositing the snow to its right. The second truck follows slightly behind and to the right down the middle and part of the right lane picking up the windrow left by the 1st truck moving it even further to the right and finally the third truck taking whats left of the 1st lane and the right shoulder. all the snow is progressively moved off beyond the right shoulder. Nothing goes over to the left.

The secret is simple. I am always easy on the throttle ever since I've had my 777 installed and religiously keep my rear pressure at 40 psi. I expect my front tire will last almost twice as long as my rear or at least close to 16K - hopefully.

The factory actually says 0 psi required and 7 psi is the max pressure, you need to use a syringe type pump with a zero loss chuck to add air and make sure both forks have the same pressure.

If there are progressive springs in the front then they suggest no air needed, but i'm with Spencer.

My head hurts.

I can not say for a new gen 2007, but my old 83, I ran just enough air to keep pressure on the seals. Basically a little above zero.

Hey, Marcarl , don't you accuse me of not being a long haired hippy. I did get a haircut last week though.

So I learned a tidbit of info in this video. Unfortunately it doesn’t apply to the shinko website early in the video he mentions that the tire manufacturer has the recommended pressure for a specific bike. I found pirelli website tell the recommended pressure. https://youtu.be/wHYbP2wd_Zg

I too like my Shinko's. I run 38 in front and 40-42 in rear on both Ventures. Cool video. Thanks for sharing....
