Tyre Wear

I have been using Continental's recommended tyre pressures on our Broadway for about 15k of the 26k miles the vehicle has done.
At measured axle weights of F-1500Kg & R-1800Kg these pressures are F-48psi & R-69psi.

The current tyre wear shows 3mm of tread left on the fronts and 8mm on the rears. All have evenly spread wear across the surface.

I am therefore anticipating that the fronts will require changing by 30k miles at the latest. (current wear rate approx 1mm per 3k miles).

Does anyone have comparable data for a similar vehicle carrying these type of weights?

Hi Backtrax,    
                 For my van the tyre wear is minimal.  From your figures it would be best to rotate tyres.
 Your back tyres will be out of date before they are worn to 2 mm.
You haven't stated your tyre sizes and load ratings,but 48 seems a little low for the front.

Hi there,

I agree with Mike, time to change the wheels corner to corner.  (That way they rotate the other way round.)

I have Continental Vanco 2 all round and run 46psi front and 54psi back.

Rotated at 20,000 miles they are now at the +/-36,000 miles mark and still have decent tread depth.  

Best regards,

Thought you swaped front to back same side
cos they take up a set and  should turn the same way on swaping
or so the tyre dealer said!

I have always swapped corner to corner to reverse the rotation.

Any idea what tyre dealers sell?

I have always rotated my tyres from my first car, as you don`t hear folk mention that now, thought it was old hat, I will still do so, as I will need two new tyres before the winter I will wait until them.

I really do not see the point of rotating tyres.
Clearly mine are wearing twice as fast on the front (the drive wheels) so no surprise there eh!
The overall wear rate of front and back does not change by rotating them - all that is achieved is having to change 4 at a time instead of 2.
My original post was simply to canvass views on the wear rate - not to open a debate on old wives tales.

In my experience 30k miles on the front is pretty good going, last two vans fronts (both boxers) required changing at about 25K, but they both got a lot of heavy use in a mixture of weathers both v cold and hot. Whenever static I always cover my tyres to protect from UV damage too. Alternatively you are a much better driver than me! 

I agree with Backtrax, if all your tyres wear out at the same time, you need to buy 4 (or 5) instead of 2. Some tyres are directional, probably not commercial tyres though, and should not be fitted the 'wrong' way round.

All well and good re wear BUT what about micro-cracking due to sun and age!!

My rears have fine cracks in them, the van has 12,446 on the clock, I will have the front ones put on the rear they are really good and only three years old according to the tyre date. and new on the front, so how will I need 4 /5 new tyres every time. ?

Hi there,

You really should read you own Posts now and then.    

Your original Post stated:

"Does anyone have comparable data for a similar vehicle carrying these type of weights?"

The answer is "Yes" for comparable data, "Yes" for a similar vehicle and "Yes" for type of weights.

All anyone has done on this Post (myself included) is to point out that tyre wear is a function of:

o  Make and model of tyre.

o  Tyre maintenance.  (Pressures, protection from UV, rotation etc.)

o  The way the vehicle to which the tyres are attached is driven.

o  The age of the tyres and their corresponding condition.

Failing to agree with something does not make it an "old wives tale" it may be that it is "the voice of experience from which you may learn".   

Best regards,
  

We are always advised to have the best tyres on the back and not to rotate them. The reason is that a rear tyre blow out is a lot harder to control than a front one so it makes sense. 30K out of a set makes sense - buy two tyres, put them on the back and wear out the fronts again.

My oh my - how some of us do not like to be questioned !!

I've never understood the logic in this   The front wheels do most of the braking, all of the steering and the power transmission on my van. If a back tyre blows out, I can still steer, brake and accelerate/deccelerate. If a front one goes I lose a lot of, if not all, of this control.

Hi Backtrax
I'm not sure if this is any help, I purchased my 09 Nuevo with 16k on the clock 3years ago and  replaced the two front continentals with Hankooks , as the tread depth was down to 2mm.
Part exchanged vans to a Sigma EK with similar mileage and front tyre wear, replaced them with Hankooks.
The Hankooks on the front of the Nuevo still had 7mm of tread at 25200 miles.
The Hankooks are my choice of front tyre on my van, i find them ideal for my style of driving, I'm counting on getting 25k+ miles on the replacements.

Keep yer heed boys.

There are a few videos on line comparing a rear blow out with a front one. It sounds wrong but the rear one is much more difficult to control according to the experts. Thus I always have best tyres on the back 

AA advise - they don't sell tyres....

Hi there,

I checked out the link but as far I as I could detect they don't mention rotating tyres.

However, they do mention the requirements for "directional tyres".  They obviously cannot be rotated "corner to corner" but having them fitted results in a few complications with regard to spare-wheels!

Logic dictates that IF you have "directional tyres" AND you want to replace the wheel at the roadside in the event of a puncture you MUST carry either:

o  TWO complete spare-wheels each fitted with the relevant tyre for "left" or "right", OR,

o  ONE spare-wheel rim AND a tyre AND a pump so that the tyre can be fitted at the roadside to suit whichever tyre ("left" or "right") is punctured!!

As if life isn't complicated enough already!!  

Best regards,

In response to the fact that the rear tyres will need changing for age not wear. 

Its been said on here that 4 to 7 years is the life of a tyre.
Not my view i hasten to add.
This is an emotive subject ,hence over 50 related threads.There is no one correct answer for all.
Many front tyres wear uneven, due to tracking faults and road camber/suspension settings and speed in corners,as Dutto has found.  
So if they go to the back you can save them being changed early.

Mike

Hi Ian, I have directional tyres and different sizes as well.on my Merc. However for a puncture i have a space saver wheel that can be used on any corner.

When was the last time you changed a tubeless tyre at the roaside Ian? and then inflate it with a 'standard' 12v compressor?   It can be done but it's the kind of thing you buy your 'peas of mind' for.

Frank,

How about "Never!"     but then again I wouldn't buy "directional tyres" either!

I've changed a few tubed tyres on cars and motor-bikes but with tubeless tyres getting the bead off the rim is a job too far for a grass verge!  

On the quad bike I carry one of these repair kits ....

.... whereby you ream out a hole and stuff some self-curing "string" into the hole you have made.

Never used that either but have it for "peas of mine" when not on a road.
