Correct me if i,m wrong. I had a puncture on the drive axle and had a new tyre put on, as you do, if the paired tyre is about 6mm, will the new tyre wear out quicker? I believe it will but an anonomous, anonymuos, anonimus, unknown person says it won,t!! :confused:

ps how do you spell anonomous?

Any difference in tyre tread depth on twin wheels will make a difference to wear. The tyre with the greatest tread depth will be doing all the work as it will have the greater circumference. The difference in wear will be very marginal though I should say.

it will wear quicker & also run hotter, risking knackering the new tyre :cry:

There is, I’m sure, a regulation covering it, don’t think 6mm would be too much of a problem, but a new one next to one thats been cut & is down to it’s limits would be, basic common sense would tell you that anyway :wink:

I was told by a tyre fitter that the old tyre would wear quicker because it has the smaller circumference and would have to skid to keep up with the new tyre that has a greater circumference and so will travel a greater distance per rotation. :question:

Nikos right the worn tyre will wear out in no time.

WHAT :question: The new tyre will have a greater circumference than the old tyre, so tell me how the smaller one will wear out 1st when it doesn’t even touch the ground :question: :unamused:

Basic lesson in the bleeding obvious needed I think :unamused: :laughing:

the newer tyre will wear out quicker but if it was on our fleet the tyres would be swapped back to at least a matching pair or a full set would be fitted.

Exactly and it won’t handle right and will wheelspin a lot easier.

How about connecting the two valves to balance them

Thats not the problem here, the tyres are a slightly different size due to the wear. “Balancing” or lowering the pressure in the new one will just destroy the carcass.

Mind you I suppose if you over inflate the worn tyre and it blows out the problem would be solved after the tyre fitter brings you another nice new tyre :stuck_out_tongue:

The Spanish do use a system of connecting the dual wheels and can even inflate tyres as they move. all good till the connecting hose gets caught on a kerb or gate post :smiley:

EDIT.
Im just going to add my view that modern tyres do not blow out (on general haulage use) unless there is damage to the carcass anyway. Worn tyres will puncture more readily than decent ones so probably replacing the full set on a drive axle together will make sense. Only my view from my experience though.

To newmercman, once your trailer is loaded you will see that both tyres are in contact with the road. Even with 6 mm tread difference. Like they all say, best to match up two new tyres and keep the old as a spare.

Fit super singles on the drive axle , they have been doing it in the states for a while !!!

exactly the same on my "fleet "(1) :laughing: :laughing: :laughing: :laughing:

Just don’t fit Bridgey. remixes as large bits of the tread come whizzing past the cab quite frequently!!! :smiley:

Our newer trailers have pressurised hubs that keep the tires up to pressure.No need to kick the tyres on pre trip.A braided hose runs from the outer bearing cover to the wheel where the valve stem would normally be, the whole hub assembly is connected to the service air tank on the trailer. Don’t forget to bleed down the air tank before servicing the hubs. :stuck_out_tongue:

I’m switching to super singles on the drives next time.My mate has 260,000 miles on his Michelin X Ones and they still have lots of life in them.

That’s correct mate, but the extra force exerted on to the new tyre will transfer to the side wall, that can’t be good.

the new tyre will run hotter but the old tyre will wear quicker as it is dragged across the floor in relation to the new tyre…that’s just the way it is…the old one will be bald pretty quickly…5mm is the usual difference that is allowed…a new drive will have upto 26mm of tread depending on the make. :confused:
