All 4 Tires wearing on Outside
« on: May 16, 2011, 12:13:23 am »
I have an '08 Honda Fit that came with Dunlop SP 31 A/S (crap!) tires.  Currently they have 27,800 kms on them and I noticed that all four of them are wearing heavily on the outside.  Bad enough so that the outside tread will probably be gone in a couple of thousand kms.
It's not the tire pressure as I check it regularly.  The car does not pull to either side or wander.
These tires are not directional, but are marked "outside" as they do have an offset tread pattern.  At least I believe that is how you would describe them.

So what's up with this tread wear?  They are crappy tires: very noisy, worse than the snow tires, and have terrible traction on wet roads.

Thanks
Do the means justify the end?

The word is asymmetrical and it`s common that the OEM tires are less than fantastic (crap).

I had OEM Dunlop SP tires on an '05 Civic for about 10K kms.  Outside wear was noticeable on the front and rear, but more prevalent on the front.  I switched to Nokian WR's for the remainder of the time I had the car, and never noticed outside wear again.  And ya, crap was a good word for those tires.
Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction, and skillful execution; it represents the wise choice of many alternatives.

If you're going through hell, keep going.

Time for new and beeter tyres.

The OEM BS tires on my 07 CX-7 were crap as well, couldn't even get 20,000Km out of them on mostly summer highway travels.

You have an alignment problem.  Even the best tires can get uneven wear if the alignment is off - and even the crappiest tires can wear evenly if the alignment is good enough!

Just be aware that published alignment tolerances are generally too wide to assure good tire wear.  You need to have the alignment within the inner half of the spec.

Plus, many vehicle manufacturers have alignment specs that are designed for good handling, and not for good tire wear.  Any spec that results in more than a degree of camber is prone to problems.

Our '07 Fit with 25000km and those same not very good Dunlop Sp31  is wearing evenly and slowly.   To be fair, only about 20K of the 25K is on those as its on Blizzaks all winter ( and they are wearing evenly as well.

Sounds like an alignment problem to me.  Here is a nifty web page with some nice graphics that illustrate the various issues possible with bad wheel alignment:

How gentle or hard do you take your curves?

Could be. I have a 50% chance. OP says no wandering. Excessive toe and it will track like a missle...

My wife usually drives this car, gently I think!  When I drive it, it's a similar fashion.  My hotdogging is on a two-wheel Honda.
The car has been treated very well and hardly ever abused.  I just can't see pushing a Fit like it's a Porsche. :-[
