Not a brilliant review here

First photo is rear, second is front.

I’m starting to think the general consensus is to bite the bullet and lay out £600 on a set of four branded tyres.

I’m thinking of giving the mechanic a call in the morning prior to him seeing it on Monday and suggesting I get 4 new (or 2 sumitomo) tyres on it.

Before forking out anymore money, swap tyres front to back. Wear some builders gloves to save knuckles. I have done it on my car a few times as I have 2 spare wheels so I swap out the 2 most worn & the 2 best go on the front. About one hour work. Procrastination, mankind's greatest labour saving device!

The new were on the back when the noise started, since swapped front to back and the noise is still there sadly.

Always worth spending a little more money on decent brand tyres IMHO.
If I've never heard of it, or can't pronounce it, I'm not fitting it to my car.

I'll second Bossbob.

You tend to get what you pay for with tyres.

But your life and that of your family's can depend upon your tyres. Jules

The tyres that you have pictured seem to have regular sized and spaced blocks around the circumference.

Dearer tyre (like Pirelli for example) have blocks of different size and therefore spacing, therefore they do not set up resonant frequency noise at certain speeds.

My views on tyres are in this topic.

My tyres in this thread. The tread & sides are various sizes. I looked a bit closer this time & never really noticed just how much the variation is.

I never knew there was so much to consider on this.

I’ve sourced 4 Goodyear efficientgrip2 that are rated B for econ A for weather and B for noise for £470 total.

Can get these fitted tomorrow, I think I’ll double check with the trusty mechanic first and go for it unless anyone tells me different.

So the latest, tyre garage don’t really want to know.

Ive spoken with JLR who said if you’ve got two new tyres on the rear axle matching, and two part worn on the front they wouldn’t expect that to be causing damage to the drivetrain and pointed me towards it being the rear diff.

I think I’ll have to just wait to see what the mechanic says Monday and avoid driving until then.

If you have an unused spare stick it on the rear left, it's the rear corner you hear the best from the driving position, & see if there is a difference. Procrastination, mankind's greatest labour saving device!

If the noise only appeared straight after the new tyres were fitted it is likely that the tyres are the cause. Noise from a wheel bearing would tend to increase as you add force to the effected wheel bearing by cornering. The nose bearing on the diff tends to cause a droning that increases frequency with speed. You have to remember that the rear diff is not really under any load at the speeds you’ve mentioned the noise occurs at unless the Haldex is malfunctioning so drive or overrun wouldn’t really make a lot of difference to loading and noise.
Have you checked the tyre pressures? Tyre places are notorious for pumping enough air in to pop the bead on to the rim then fitting the wheel as is. They certainly don’t know the correct pressures for every model on the road and most wouldn’t ask or look it up. And they probably used an air gun to do up the lug nuts even though that goes against the advice from manufacturers and didn’t use a torque wrench.
