Hi guys, I know I've had this partially explained, but I need to know what goes with what.
My understanding is,
Rag rear needs a rag front. No metal belts internally, no stability in the sidewall, good for drag cars.
Street Radial on rear allows a standard street tyre on front. Street radial has soft sidewalls, but still gives stability on the street, allowing for use on street, mainly driving to and from track on dry roads.
Now, Mickey Thompson ET Street Slicks, constructed of bias ply.?. Is this similar to the radial slick in allowing you to use a standard street front tyre, just constructed of softer rubber, or is it more like a rag and needs a rag front tyre?
This may be a silly question, as maybe a rag is a bias ply tyre. If that the case, why call it a DOT street slick?
I'm confused and would love to understand it.
Sorry for going into this again.
Cheers and thanks in advance

When working with ET Drag Radials use 1 psi adjustments to see change.
A radial will perform quicker the more air you can run.
ET STREET RADIAL
On the racetrack DO NOT use starting pressures below 11 psi.
Recommend pressures for:
P295 and larger sizes: 12-16 psi
P275 and smaller sizes: 14-18 psi
For suggested highway use inflation pressure in Mickey Thompson ET Street Radial tires, contact the Mickey Thompson Tires tech department at (800) 222-9092. Please have your OE specified tire size and OE cold inflation pressure (located on the vehicle’s tire placard), as well as the new tire size available for the tech staff.
A couple of selected bits of advice from the Mickey Thompson website.
Essentially you can think of tyres in two categories for your purposes. Radial and non radial. The ET Street is a non radial and you really should use a non radial up front as well.
The ET street radial is an excellent street tire for everyday use if you don't do too many km or burnouts. I got 5000 km out of my last set before they hit the wear bars ( approx 2.5 mm tread left). They are excellent in the wet even when worn. Certainly much better than any other high performance tyre I have tried.

Yep.
Rag is slang term for Bias Ply.
ET street is a rag tyre. It is DOT approved in america, NOT AUSTRALIA. Must use rag front tyres.
ET street radial is a radial tire, again its DOT approved in america not australia, but i've never seen or heard of anyone being pinged for them.
Cheers.

Thank you!!!
This explains it all and leaves me with no more questions.
I didn't realise that the Street Radials are not Australia legal. I thought DOT approved on the sidewall just made them legal.
Also surprised to hear they are good even in the wet. With the tread patern I would have thought aquaplaning was a given.
Thanks again guys

As with most things Australia is #@$^%& in the head with tyres.
Tsingtongtan tyres for $60 each are perfectly legal, but high quality ET street radials arnt.
Go figure.
A bit of civil disobedience is a good thing, just run them.
Cheers.

Out of curiosity, and not that it would overly concern me, but if you had an accident with these tyres on and it was your fault, would the insurance company pay, or could they get out of it?

That's a trick question right?
If they can get out of it, they will.

Sadly, thats probably true.
But Mud tyres like MTZ's are illegal to, and i know a fewl ads who have pranged there fourby's and been payed out.
Best to call your insurance provider and ask? Or put the ET street radials on the policy?
Cheers.

We do a fair amount of insurance repairs at work and you would be astounded at what they will repair, and not any insurance mob in particular.
For instance, near new VE ute in at the moment, has had RHF impact with gutter and roundabout due to loss of control, has 2 bald rear tyres, LHR tyre has canvas showing the full circumference of the tyre, and yet we are repairing it.

Same deal as ET street radials. Dot approved in the US not Aus, TMK atleast.
Dad got pinged for his a while ago back when the local Cunning Stunts tablry was having a massive crack down on fourby's, obviously a 60 year old driving a jacked and boosted patrol is a massive threat to society.

Im not 100%, we certainly couldnt find anything to prove they WERE legal....
Tyre shop that sold them couldnt help...etc etc etc.
Oh and before you ask, 33x10.5's, so legal size on his car.

The ET street radials are legal. I went to the bother of contacting vicroads on this issue. They directed me to the rim and tyre association as the arbiters.
I discussed the tyre with the president and technical officer who arranged a viewing of the tyre by an authorised representative. The tyre was declared legal for street use in Australia.
