Will one fork with a "soft" spring or the lack of fork oil in one side cause abnormal tire wear? Could these conditions result in cupping?  |

On the valk the forks are different anyway (and on many bikes), one side dampens on compression, the other on return. Cupping is usually due to low pressure...the valk notoriously wants higher pressure than was in the manual for optimal tire wear. Also, they do wear out the left of center side of the front tire somewhat faster (as your are sitting on the bike) due to road crown/turning preference etc. All that said, a completely shot front end can result in abnormal tire wear, but it has to be pretty far gone and is usually the pressure thing... |

My standard is wearing both tires on left of the center of the tires. Tires pressure is always normal, as specified. I understand everything said before, but in my situation it looks like it is driven at a constant lean to the left. The last set of tires had to be replaced due to complete wear on the left side with at least half of thread remaining to the right of the tire center. Any ideas or suggestions?

sshlitz, In the US motrcycles wear the tires out on the left side faster than the right side. That is very normal! This happens because we drive on the right side of the road which causes us to spend more time in left hand turns than in right hand turns. For that same reason, people that ride in countries that drive to the left of center tend to wear the right side of their motorcycle tires out first. There is an explaination of this in the shop talk section. Wolf |

Not only that, but riding on the left means that all crowned roads are harder on the left side of the tires, riding straight and level. Generally, the narrower the road, the taller/steeper the crown.
I can find no such wear on my Darkside rears, but my fronts are always worn left over right. Need one right now.

As several stated above, wear on the left is normal. Also, pressure "normal" may be low...I run my front at 44psi and get better wear. The manual specs a much lower pressure... Here's some reading on the subject http://www.rattlebars.com/tirewear/index.html |

Same here with the left side wearing out faster. The dealer put a spin on this as we are more custom to leaning over more on the left side verses the right due to the throttle. After hearing this and paying attention while riding it is true with me. I have a right shoulder issue that prevents me from really getting into a right turn lean. The left is no problem. Not gospel truth but, just something to think about while you are out there on the twisty road.

I have a 200 I/S with over 100K, so I've been through a few tires. I do experience some extra left side wear, but yours sounds excessive. I've run through everyting in my mind and can't come up with a good reason. Do you run the darkside on the rear? Althouth I prefer the MC tire I have run some darkside and I can see where it might give you some extra wear holding the bike in the turns. I have been reading these articles and everyone seems to be right about raising the tire pressure. I've been running mine factory and it causes too much center wear and cupping. Wish I could be more help.

Thank you fellas for all your inputs. I was really concerned ever since the previous set of tires. I thought I might have a twisted frame ( I bought my bike 2 year ago used). But since the consensus is left side tire wear is normal, my mind is at ease. I will definitely follow your advise to increase air pressure and when the time comes for a new set of tires, I will go CT on rear and MC back tire on front. I put only 7-8k miles a year, however, changing tires even once a year is too often and, besides, it costs an arm and a leg. Thank you all for sharing your knowledge and expertise, I am learning a lot from this site.  |

I find myself riding in left (passing) lane, when on a divided 4 lane road that has median drainage. The way the road is crowned, riding in the left lane puts the uphill slope on the right side of the tire. It's like riding on free rubber, if you have a tendancy to wear out the left side of the tire early.

Thank you Fudd! I am riding in the left lane now, as you suggested, and increased tire pressure to 40 plus psi, as many others suggested and started to see the difference! Thanks a lot friends for sharing you knowledge and expertise. Sam Shlitz |
