Lean to the Left

[vej]

I'm the original owner of my 08 Mastiff. All my rear tires have always wore out to the left of center. I've always had a slight lean at certain speeds in order to go straight. I've had some mechanics tell me that is common for 300 rear tire bikes, but I was wondering how many of you have the same issue??

I've got about 70k miles on my bike now, so it obviously has never prevented me riding. But if it's correctable, that would be great. Ideas?

Thanks!

70k! Congrats Sir! Job well done there

I'm still a firm believer the crown in most roads is the culprit in these wide tires wearing left of center..

If ya don't regularly ride in the rain, just watch when you see it getting worn and then just flip the tire on the wheel and get another 2500 miles outta it The directional tires are only to wick the rain anyway.
If you ever follow other bikers, look at how much the bike leans from perpendicular to the road.

I've experienced the same issue with mine (also a 300), never had a problem with any other bike doing this, even with 200 & 250 rear tires.

May want to check the alignment, I have a 300 and it usually wear straight down the center.

I always have strange thoughts....Is it possible areas with a lot of rain have a more pronounced crown than a state like Nevada or Arizona? Any city engineers out there?
And I recall one guy posting that the off center tire wear improved when he moved his fat wallet to the other pocket of his jeans. The idea was that the fat wallet caused him to sit off center and he corrected the weight imbalance by shifting the bike slightly.
Just sayin'........

My wife's brother is a civil engineer. I gave him a call to ask a few questions. According to him, the crown can vary state by state depending on a variety of conditions, (weather can be one condition). He did not know any details other than the state he lives in. Just a little information for you guys.

Typically a sewer waste pipe in your house has 1/4"/12" pitch for comparison, the roads minimally have twice that, no wonder they wear on the left

Unless you live in Europe, then I guess it would be the right side that wears first, right?

How much air pressure are you running? I believe that FL has a steep pitch because of most of it is so flat and of course the storms they get.

 

[heybaylor]

the left side wear is caused by making wider faster left turns.
right turns are slower and shorter

My . Square your a$$ up, switch from left to right of center of your lane and ride more north east and south west that way you don't have to fight as much side wind.

Just ride on the other side, it's easier

Or do like Ker... and hang your bike on the wall in the garage.

Wrong John. your picture answers your question, unless you are riding on the wrong side of the road. Around Suffolk, all the back road are well cambered .

That's my point Paul, they do ride on the wrong side of the road in some contries so therefore like in JR's pic, your tire will wear on the right side instead.

 

[BWG56]

I give up. The roads in Suffolk are all flat and I'll get a picture tonight if it ain't raining.

I shoulda had Sue take some pics when we were riding behind ya all, there was a definite lean
