Tyre tred

Personally i tend to get around 8000 miles out of set of tyres, but ymmv.

Wow. I’ve never been anywhere near as low as that. Many, many years ago I had a 5 cylinder Audi 100 avant and went through front tyres in 12-14,000. Last car was sold at 44,000 miles and had three new tyres, two front ones due to wear and one rear due to a puncture. 

I have a 250hp front wheel drive Fiesta, it eats tyres for breakfast. Good fun.

In October we got 2 new front tyres.

We just had a service done and they claim the tred is now 6mm, 4 months in 2mm down? Im not 100% sure but do think this sudden 8-6mm tred drop has happened before..? Are they over wearing? If not then why do 8-6mm drop happen so fast over 6-2mm?

I also noticed with these new tires we have had done they have put the tred down as 6mm? not sure why this is considering they are brand new?

Too add again, our drive is at a corner so you have to turn a full 180 from the small side road to mount up it, kerb is dipped etc, but drivers side always mounts the drive before the passanger side.. will this cause excess wear or am i over thinking? obviously this is usually done at a pretty slow speed.

Also, how many miles can i expect out of each set of tyres? i know it generally depends but typically what is under performing?

The answer to your question depends entirely on your journey profile and your style of driving.

The rate that tyre tread wears down isn’t linear; i.e. the first ‘‘mm’’ of tread will wear down quicker than the second ‘‘mm’’,...the second ‘mm’ will wear down quicker than the third ‘mm’,... and so on.

The deeper the tread the quicker the wear.

Acceleration, braking, cornering and urban  traffic stop/starting all take their toll. Underinflated or overinflated tyres is a definite no-no. Correct wheel alignment (‘tracking’) is also very important.

I had a Vauxhall many moons ago that did 73k miles in two and a bit years,...on the same 4 tyres. All the tyres were still legal (just!) when the car went back to the lease company.

A very large percentage of the 73k miles was motorway driving;...mainly constant high speed, with little in the way of acceleration or braking (except when necessary of course).

Urban driving with excessive acceleration/braking/cornering is the tyre tread killer.

I’ve just had two new front tyres on my car;...17k miles,...mainly urban;...and I’m certainly no boy-racer!

Did you measure the tread when you got the new tyres fitted to see if they were 8mm?. The last 4 tyres i had fitted were 6.75mm when they were brand new so don't just assume they start at 8mm. I measure them every few months and tend to find that they wear fairly consistently over the lifetime of the tyres and don't seem to wear more quickly when they are new.

Are you sure about that? Isn't it the reverse?

After the first mm, the rolling circumference of the tyre is smaller, so the wheel has to turn more often to cover the same distance, and so the second mm will wear more quickly than the first. Albeit only by a fraction of a percentage.

New tyres are 8mm. Also make sure your not measuring on the wear indicator as that would take around 2mm off.
the front tyres have to deal with acceleration, braking and cornering forces. Obviously driving like you stole it will eat tyres 

the secret to getting the most out of your Tyres is to have new tyres on the rear and the tears moved to the front. On fwd  front tyres wear quicker then the rears this leaves the rear tyres to degrade over time. I seen tyres with 6mm all cracked up

Incorrect, if you actually measure a new tyre you will find they do vary and won't necessarily be 8mm.

There 8mm for all season, 9 for some winters and up to 10 for off road

There is no standard tread depth for new tyres, all manufacturers can differ.

Obviously there will minor differences if your using engineering measuring devices, but if your using a normal tread depth gauge you’ll find it pretty much 8mm. No point getting a three decimal place resolution for tyres

OP if your constantly getting tracking/alignment done that points to poor driving style ie bumping up and down kerbs or  hitting potholes
