Took the S out to try the airbox mod and managed to scrub a little more off the tyres than I was expecting.....the end result is that they are down the markers

I've got a set of,literally, scrubbed S02 JZ's maybe done 500 miles tops and I am worried that if I fit these they are going to be ruined after a day on the airfield

Sooo are the markers there to warn you they are illegal or to warn you they are 'getting' illegal

I can't afford to buy a set of rear tyres and muller them, my pockets just aren't that deep

Zero - under no circumstances should you change the tyres before the airfield day. I shredded my rears at Heyford (all my own fault I hasten to add - but going THAT sideways was too much fun).

Just be careful for a few more days, and take another car if it rains

what's the fine if you get done?

The fronts have loads of tread left......hardly worn at all

If you're stopped, you will most likely be given 14 days to appear at a Police station with the ticket they give you stamped by an approved MOT centre confirming any vehical defects have been corrected, i.e. you've got some new rubber! Unless of course they consider your car to be dangerous.
Not that this has happened to me in the past...

What's the deal with "markers"??......didn't even realise that we had such a thing to tell us that tread was getting low. Where are they etc?. I'm on my original SO2's with about 12500 miles on the clock......they might be getting a little thin!.

If this happens to you, talk nicely to a nearby fellow owner and borrow their wheels for the day

Inside the tread grooves, you'll see some little bumps that are raised 2mm (IIRC) up from the bottom of the tread - there's usually some sort of indicator on the tyre wall pointing you in their general direction.
The legal limit I believe is 1.6mm, so if you haven't quite hit the markers, you've got a few miles left, although an airfield/track day stands a fair chance of taking you over the edge.

in that case I may be lucky.......the problem is that I've always been very heavy on my rear tyres and the fact that I am running 225 S03's is serving to exaggerate my driving style

I can't see them being legal at the end of the airfield day unless I refrain from getting on the power too early....and for me that's the whole point of the day
