Mixing new and worn tyres

[barkern Junior Member Find all posts View Profile Close barkern]

Ok guys need some knowledge...

Some idiot spilled a box of drywall screws in my street a while ago and i managed to pick up 3 in my drivers side tyres (front and back) grrrrrr...it could have been worse as all my housemates have had punctures and my neighbour with his $800 a piece run flat tyres for his merc got done.....

The front tyre was fixable but apparently according to the 'expert' the back tyre isnt as its too close to the shoulder (doesnt look like it to me 20-30mm) anyway just wanted to know that if i get a new tyre will the extra circumference in the unworn tyre cause wind up in the transfer case and cause damage (like the 4wd audis and volvos where you have to replace all tyres at the same time)

apologies if there is a thread already discussing this. If there is please post links and close this one.

Ta!

I dont think the extra tread depth will make any difference, but I was always told to put the new tyres on the front.

Interesting - I just got two new tyres and although I wanted them on the front I was told you should never put new tyres on the front (until they have done 5 - 10K) and they put them on the back.

This makes a lot of sense so where do you put your new front tyres if you replaced all five?

OK, I should have been more specific - they said if you are mixing old and new then the new should go on the back. Not much choice if they are all new

Hey treckrider, I honestly don't know why,I discussed this at work with the guys and the general consensus was that new tyres go on the front because they have the most tread, most grip for steering and braking and wet weather driving ei you car has the best chance of control. not one person here agreed that they should go on the back. so I spouse this makes sense ???

Hello Barkern,

Depends on the amount of tread left on your tyres, if the survivors are nearly worn out replace 4 and keep a spare. If you have been rotating all 5 tyres use your spare to replace the damaged tyre on the road and buy a new tyre for the spare. When the time comes buy 3 new tyres and you will have 4 good new tyres for use on the ground.

Several years ago a friend of mine had a Sanyong Musso and had two bald tyres and two with a little tread, he saved a heap by buying two second hand tyres with almost new tread. ( about $350.00 savings ). He was very proud of his efforts until the Musso spat the front differential at 110 kph on the freeway. Warranty was refused because he did not replace all four tyres when two wore out. ( final cost was $4500.00 but he did save the $350 ). You dont have a Musso in any case so you will probably be ok.

regards

Ross

That's OK Jim, it didn't make sense to me either They said they were told this by the tyre suppliers - I think the argument was that until the tyres had 'bedded in' they would have less grip than the older ones. Do bear in mind that my other tyres had only done about 15,000 km so weren't that worn anyway.
