tyre rotation and noise

gooday Nutwood : What has dean suggested is what coopers & mickeys suggest , that makes each tyre move to each corner of the vehicle after a few rotations . the idea is that it keeps the tyre flat & less noise !!!!
so they say

Its reasonable to expect more noise if a tyre now runs on different bits of its casing as it beds into the new position.

Good to rotate all 5 often.

Probably worse when cold.

Try running much higher pressures to reduce noise a bit.

I note that in a recent tyre test test Bighorns were considered noisy compared to BFG MT (KM2)

My vote would be its the newer tyres.
If you went lhf to lhr, your basically doing the same as swapping the two fronts side to side as far as the load on the tread face is concerned.

Anyway.

With larger tread block patterns, you will get tread block movement, and this can often be misdiagnosed as incorrect toe in wear.
With larger tread block, best to rotate front tyres side to side, so you wear the tread blocks evenly, say every 5000km.
Then rotate front to rear on same side as it "reverses" the load seen on the tread face.

Not sure how many of you have seen tractor tyres, the ones with the large tread bars, you can see the ones whom do alot of black top running, as every other tread bar is quite badly worn/ scuffed.
Some tyres do it more than others.

If you have noticed more tyre noise, its either the new ones on the front, or some noise from the tread blocks with load etc on the rear.

hope that helps.

You sure your front end isn't out...That can make a difference with Tyre noise..

I rotate my tyres every 5000km with the oil change.. I always swap the direction... your tyres had 15000 on them before the rotation.. if your car is wearing them down they will have a fair amount of bedding in after 15k... thus when reversed they will have to rebed - hence the extra noise.. if done regularly the noise is barely noticeable..

btw my BFG muddies are coming up to 95,000km and have heaps of tread left and nice even wear... I put the even wear down to the regular rotations.
