What is the minimum tread depth on a bike? would i be right in thinking its about 1.5mm - 2mm

It kinda depends what you are riding/driving:

[Laws RTA 1988 sect 42 & CUR reg 32]

Tyres. Tyres MUST be correctly inflated to the vehicle manufacturer’s specification for the load being carried. Always refer to the vehicle’s handbook or data. Tyres should also be free from certain cuts and other defects.

Cars, light vans and light trailers MUST have a tread depth of at least 1.6 mm across the central three-quarters of the breadth of the tread and around the entire circumference.

Motorcycles, large vehicles and passenger-carrying vehicles MUST have a tread depth of at least 1 mm across three-quarters of the breadth of the tread and in a continuous band around the entire circumference.

Mopeds should have visible tread.

However, riding a bike with 1mm tread is not something I would condone. I normally change when it drops below 2mm as the last mm' tend to wear fairly quickly.

This is taught in CBT.

are you insane ?

When they give you the CBT certificate it erases all knowledge of the previous 8 hours.

(it's also in the Higway Code, which is where I took the quote from)
