i have a Harley Heritage Softail '07 and it eats up tires terrible. i only get 5-6k miles the rear tire.  been using the Dunlop MT90 OEM..Anyone got a better tire???

That sounds low, but not completely out of the question depending on your riding style.  You got a lot of low end torque so if you quick start I could see that type of wear.  I have tried ever tire out there and found the stock Dunlops to give the longest life.

This has also been discussed in ohter forums and you may want to read through some of those...

I've seen this post somewhere before. I get 15K on my Roadking. But, I have to replace both tires at the same time. In the past, with my '98 WideGlide I got 10k on the back and 20K on the front. Having to replace both tires at the same time is pretty expensive. As for your 7,500 mile dilemma, there are any number of reasons but I figure it's probably the way you ride and the tire pressure. People talk about checking oil everyday before they ride. I don't believe that's as necessary as checking tire pressure regularly. It doesn't take much deviation from recommended tire pressure to create issues. Cupped tires is one of the most common problems associated with tire pressure.
But hell man, back in the day we didn't change tires until the chord showed. Then again, we were young and stupid, not to mention reckless. More of us are concerned with safety these days (a good thing) and I believe doing preventive maintenance, scheduled maintenance, and frequent overall inspection procedures is the best we can do to stay safe and extend the life of our motorcycle parts.

I'm lucky to get 8,000 miles but I am in no way a tame rider... I tend to be somewhat aggressive, mostly due to the lack of foresight from the idiot cagers! Plus pumping up your motor tends to kill two vital components, tires and fuel mileage, but thankfully I can always afford a few tanks of gas vs. filling up my big ass Suburban (which needs about $1100.00 worth of tires next month)

fishtime, what is your style and air pressure? As mentioned above tire pressure is neglected alot by some riders and that will make a huge difference in your wear. Normally get around 12-16K on my bike, but I met a gentleman that would be lucky to get 5K.

I have tubeless mags that require 35 PSI front and back and I'm a stickler for air pressure... still the torque just eats tires:-)

my fatboy got 2500 miles to a set of tires its a 07. look at the frt wheel is it centered in the shocks.if not the way I fixed mine 08 frt lower shocks with 08 wheel caliper,bushings.then for the rear 08 wheel ,caliper,caliper bracket,bushings,and swing arm.then u have to have left rear swing arm bracket its welded to tubes on frame it moves the wheel to the left app 1inch. you also have to have 08 frt wheel getting good milage now also run perrilla night dragon tires

Wow, 2500 miles on a set of tires... I would be replacing tires ever 6 to 8 weeks!!!!

MY last set of Dunlops on my '07 Road King were at 8,600 on the rear and 13,200 on the front when replaced!!!
