What the heck is up with my front tyres?

First of all - I run the same tyres on all four corners; Uniroyal Rainexperts, 195/65/15s running at the correct pressures.

Here's the rears, almost good as new;

And um. The fronts!

Again - identical tyres, of similar ages and mileage replaced in pairs. The front left is the same as the front right in regards to condition, and the rears match each other too so its not like one wheel is wonky here...

I inherited these tyres from the previous owner and have been on them since January but I'm not sure what's wrong here - I suspect alignment or "keen" cornering to be at fault though.
 
Have you had an alignment check done? Usually done for free and if you go somewhere with a hunter system you get a nice printout - adjustments would be charged for obviously.
 
That's my next step, I'm going to see if I can get it checked on my way home tonight. It just worried me that the fine rib pattern on the fronts seem to have been smushed together unless they are just that worn its got to that point. The centre is fine however.
 
Are the inside of the front tyre edges worn like the outers?

If so, then either under-inflation or a suspension fault on each side (unlikely) / If not, then the problem is excessive toe-in. But could also be (very) spirited driving!
 
The shoulders on my front tyres are wearing quickly at the standard tyre pressures too. I have increased the front pressures a bit which seems to be helping.
My last Accord had 17" tyres with an XL rating and never had these problems.
 
The alignment is out if you're wearing unevenly across the tyre.

Now the front will generally wear quicker than the rears as these tyres have to handle the steering as well at the weight of the engine, breaking, etc. So quicker wear on the front compared to the rear wouldn't concern me.

As a general rule, wear on the outside means the toe is too far in. On the outside, means toe is too far out. However, camber is also involved.

Looking at your picture, it seems you are scuffing the outside of the tyre, I'm guessing you're toe is too much in. Ideal spec for toe is 0mm.

Oh and those rears are extra special the tyre size is printed on backwards! :)
 
Haha that's my fault! I took the pictures at different angles and then flipped them so the tread pointed in the same direction for comparison :) I've swapped fronts to rears for now and the rears are evenly worn. Fronts are wearing more along the outside edges with scuffing.

I'm thinking two new front tyres and a full alignment this weekend :)
 
Don't you mean two new rears now? Since you've move the original fronts to the back?

And then a full alignment.... ask for a before and after printout of the settings,.
 
Just bear in mind the rain experts are quite soft tyres. I found the same when I had them fitted and they wore on the shoulders more than the centre. Tracking and alignment check showed nothing out of spec but I do a lot of driving on rural roads in Cornwall.

They were great tyres but wore a little quickly for my liking so I replaced them with some Dunlop sport blureponses which should be a little more hard wearing.
 
The same tyre as I'm getting tomorrow! I'm hoping they're a little quieter than the uniroyals too - they're not bad, but the tread pattern makes roads more "rumblier" than I like heh.
 
They are definitely quieter. I've not done enough miles to see if they resist aquaplaning as well as the uniroyals (unlikely) but the sidewalls feel stiffer and dry grip is better.
 
Got them on now, certainly better overall! Quiet, doesn't lean as much when cornering, feels much more stable.

For the alignment, the only thing out was front passenger side toe, 0.1 degrees outwards, must just be the weight at the front then.
 
I'm pleased with them too - I'll certainly be fitting them to the rear wheels when they need doing. No noticeable impact on fuel economy though (If you go by the tyre ratings, the dunlops are meant to have a lower rolling resistance)
