Does any one have any experience on installing those tires on a 07 roadking . I found a replacement for the front but the rear is not a direct replacement made by Michelin , talked to a sales rep and looking in a parts catalog and found tires that might work for the rear. Does any one know if the 150/80b16 77h will fit and work on the 07 road king or better size . Thanks Jim

The Michelin Commander IIs are great tires, but make sure the load rating (77, in this tire) is equal so you don't overload it.  What size and load rating ♦rear tire do you have on it now?  Is it different from stock?

Here's a link to a calculator for comparing the diameter of different sizes of rims and tires: http://www.rbracing-rsr.com/tirediamcalc.html

This lets you see if a new combination will change the effective gearing on your bike.  Remember that any difference in diameter will be multiplied by 3.14 for the circumference (i.e., the distance of one revolution), so a change of 1 inch in diameter equals 3.14 inches in circumference.  Doesn't sound like much, but at roughly 1000 wheel revolutions per mile, that is about 250 feet per mile...every mile.

Edited to include link to calculator.

Thank you for the advice Jim

I have a 2005 FLHTI with a 140/90B16 on the rear. That's the recommended size. Would a 150/ fit ?

Stock tires on a 2007 Roadking were MT90B16 72H front and MU85B16 77H rear.  The rear tire dimensions were 25.71" outside diameter, 5.51" overall width.

The MU rear tire is roughly equivalent to a 140 metric size designation.  Others have indicated that they had installed a 150 on their '04-'08 Touring models without issues, but you will want to do some measurements on your particular bike to make sure you have enough clearance.  The Commander II 150/80B16 77H measures 6.5" wide at the widest point, versus the stock tire at 5.5" wide.  So you will need to measure clearance on each side to parts like the swingarm, rear belt, belt guard, fender, etc.  Measure the clearances with the stock tire, then determine if you have enough clearance to allow for the wider tire.  There is also a difference in outer diameter, with the Commander II coming in at 26.06" OD and the stock tire at 25.71" OD.  One other factor is the rim width.  Stock rims are 3.0 inches wide.  I couldn't find a spec from Michelin for the recommended rim width for that 150/80 B16, but it is likely it really calls for something 3.50" or wider.

You are correct that you need to measure tire. My last Dunlop wasn't as wide as the commander II, same size tire. I also read awhile back that the 140/90B16 was the same as the MU85B16.. A 150/ would be close..
