How knackered is my chainstay?! (pics)

So, just been sorting my bike and noticed this large area of rubbing on the chainstay:
Using my calipers it looks as though it is around 0.3mm deep
I am kind of assumng this is death to the frame, or is it quite typical? It is a Cannondale F800.
There is enough tyre clearance too, but I think it must rub when I put the power down on the pedals?
In the meantime I am going to wrap it with a bit of old tube to stop it fowling that area again and again...
Any thoughts onto how serious this is?

Don't wrap a tube, stop the wheel/tyre moving to rub it in the first place! Tyres look to big for teh frame, very little mud clearance.
If the black spec in the middle is a whole in the tubing then the frame is scrap. Otherwise just watch it like a hawk for a while.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
Hi, should have said 'I have a ride planned today with friends so will put some tube over it...'
Found a loose spoke on the wheel so going to take it in for a re-tension and see if that helps keep the wheel straight.Remember Rule #50 -

I wouldn't normally point out someones misspelling but you were all over me last week
if if there is a small HOLE, it wont right the frame off, a blob of weld and it will be fine0 -
Don't you just love your last sentence. If you're going to pick holes on the whole it is probably best you write it, er, right.0

Given that your frame is constructed in heat-treated alloy, getting someone to weld a blob of filler may result in accelerated failure due to heat stress. It might be better to apply a reinforcing 'bandage' of carbon fibre and epoxy - you can buy repair kits online.Make mine an Italian, with Campagnolo on the side..0

As mentioned that tyre is too wide. I wouldn't fit a tyre that sat that close to the stays.
I wouldn't wrap it with anything, you need to be able to keep an eye on it.
And fit a slimmer tyre too.0 -
0.3 mm is about as thick as a cats cock hair, that would be no problem your wear looks a lot thicker than that!pity those who don't drink, the way they feel when they wake is the best they will feel all day

Get your wheel fixed.
Get a tyre that fits your frame.
