Hi it's my first post so go easy on me!

I just noticed my tyres have worn all the way down on the outer edge of both front wheels. The rear tyres have 'cracking' (right word?) on the outer edges. I've attached images below to make it clearer.

I just wanna check which (if any) are not road legal. I've been checking forums etc all morning, and nothing yet has compared to the state of my tyres to make it clear whether they are within the rules are not.

Hope you can help. Cheers!

Tyre cracking is not an offence, just an advisory. Splits and cuts are different though.

The law says the tyre must have a minimum tread depth of 1.6mm across the central 3/4 of the breadth of the tyre and around the entire circumference.
So, the inner and outre edges can be devoid of tread i.e. 'bald' in usual language so long as the central part has a minimum of 1.6mm. The central part has to be at least 75% of the width of the tyre. The measurements on the tyre wall will tell you the overall width.

e.g. your tyre says 185 x 60 x 15. 185 is the width in millimetres. Therefore, the central part must have 1.6mm for a width of 139mm.

Take 139 from 185 which leaves 46mm. Now divide by 2. Equals 23mm. Use a ruler or tape measure and from the outer edge measure in 23mm. At that point you must have a minimum of 1.6mm tread. (remember this is an example only)

The 'entire outre circumference' means that if the tread depth is below 1.6mm in the central 3/4, perhaps due to a skid, then the tyre is illegal.

Difficult to say from the photos but you may JUST be legal. However, being legal is the minimum requirement and if it was my car, I would replace all 4 tyres as soon as possible.

The garage folk who MOTd my car, said that one tyre was border line on one area, they said that for £40 they would swop the wheels over, front to back, and that would give me a lot more use of that tyre, as it's only slightly more worn on one outside edge, but still legal.I think I will go for that, as it's a lot cheaper than having to buy new tyres.

Tyres are one of the MOST important safety items on a vehicle.

Better get a new set of four without delay.
