MT90 verses the MU85
I have an 02 Heritage Classic. It has the MT90 rear tire and I would like to install the MU85 (higher load rating). The tire is .310 inches wider. Otherwise, no difference in physical size. Anyone know if this would fit? Harley-Davidson went to this size beginning in the 03 model year.

I think the MU85 (140) is a bit taller as well. When I looked up tires for my '06 Deluxe, it called for the MU85. Currently it has a MT90 (130). Explains why the speedo reads a bit fast

It'll fit. That's only about .155" (5/32") per side wider. I just put a 150/60-18 on my 02 Heritage two days ago. It's definitely tighter in the fender mainly around the bag studs but man it sure looks good. Mine is also lowered 2".

According to Dunlap spec chart ( http://www.dunlopmotorcycletires.com/tire-line/d402/ ) the height difference is .01 inch. That should not be an issue. I mostly concerned with the .310 inch total width difference. Hoping it is not too wide. Really like the 70 lbs load specification difference. Like the contingency.
I know guys have run the 02 and earlier bolts on their 03's so I'm suggesting to you that you'll be fine. To verify, measure your clearance between your fender bolts and the tire and see if you'll have the .155 add'l clearance needed. With weight on the bike of course, you want to check clearance with full load, in fact, on the bump stops if you can arrange it.

Harley introduced the MU85(140) & 150 to the Softail line in 2003 (depending on sub-model and whitewall or not) ALONG with changing the offset in that rear wheel on both the laced spoke and Cast "Mag".
As previously said, a MU85 (140) should fit fine

Comparing the 85 to the 90 on J&P Cycles website the 85 is only $7 more but has 2/32 more tread. That alone is worth going with the 85 in my book.
Of course if you are really rich you can get the harley logo whitewalls, about $230 ($70 more) at Surdyke HD. They look great but not worth the $70, at least not on the back.

The tires on my bike are new whitewalls. We had a warranty issue with the rear tire. I will stay with the whitewall but I really want the extra load and tread groove depth. Thanks for the feedback.
