Hi Guys.

I've had my Freelander Td4 a week now, and as I get used to it, I notice how much noise there is from the tyres on road.

It has been said to me, that it may be because the rear 'axle' has Michelin Synchrone's on it, but the front has budget Maxxis tyres on that 'axle', and that all the noise is because of two different tread patterns hitting the road, and that I could reduce the noise by having four tyres of the same make/design/pattern on the vehicle..

Is there any substance to this advice, please?

Thanks in advance for any help. Mike

I can't see how mixing tyre types will increase road noise (unless it is the transmission groaning under the difference in tyre circumference!).
The Synchrone's are a very noisy tyre, I have found that since replacing the set on my wife's TD4 the ride is much nicer and on certain road surfaces the noise dramatically reduced.

Litch, what did you fit instead?
 
Hi the same tyre setup was on mine and was killing my drivetrain see HOT VCU i had to put 4 the same make and size on i have two maxxis for sale pm me for details is your VCU hot after a run ? if so you have a big problem that nees sorting ASAP !
 
You need to check the tyre circumferences, front to rear. If they are out by too much, then you'll be activating the vcu (effectivley locking it up) and powering both front and rear wheels when your not on a loose surface, hence you don’t need 4wd. When this happens 1 or 2 things can happen:

1. tyres sound rough on road as the transmission wind up is lost via tyres scrubbing the road as you drive.

2. the ird and/or rear diff will fek up. You’ll also potentially destroy your vcu in the process.

Best thing to do is to fit 4 tyres the same make and size.

Had Michelin Synchrone's on my TD4 and they were shockingly noisy, more noisy than the Maxxis ones I had. I replaced them with 4 all terrain General Grabber ATs. (not the older AT2s) and I was amazed by the fact that the all terrains were sooo much quieter. Was expecting them to be very noisy!
 
CB40, when yer gets 2 more tyres (same make/model/size as the other 2 you have) put the 2 tyres with the most tread on the rear.
 
RichM, would they be these tyres? I remember reading about them and they said they're a bit betterer than the AT2's orf road, quieter on road, and have a shaped tread that means they dun't pick up stones as much.

If thems the ones, what are they like?

GENERAL TYRES / 4X4 / GENERAL GRABBER UHP - 215/65R16 98H TL :: £81.80 :: 4x4 Tyres - SUV Tyres - All Terrain Tyres - Off Road Tyres - 16" :: R16" - 215/65/16, 215/65 R 16 ::

Nope. They were the new General Grabber ATs. (No Idea why the new ones are called AT even though the old ones are called AT2's. Surely AT3 would make more sense?) I wouldn't trust those UHPs for off roading. Tread isn't very deep or aggressive at all. I'm guessing they're designed for the likes of BMW X5s etc.


Here's what they look like:

They look surprisingly less aggressive than AT2s but everything I've read would suggest that they're superior.

"The all "New General Grabber AT" pattern, 50% ON-Road 50% OFF-Road in the 265/70/16- Black side wall.
Just launched it is designed specifically to give the best performance in both on and off-road conditions. The new tread compound and pattern has been engineered with the emphasis on safety with excellent noise reduction and wet braking. A highly technical all-terrain pattern that really works hard.
At first glance this tyre may seem less suited to the Off-Roaders amongst us but don’t be fooled, this tyre has outperformed the AT2 in every test and the new noise reduction characteristics is a compliance that all Tyre manufactures are obliged to adhere to on future AT tread patterns and General are at the forefront of these new worldwide demands."

I've got half worn BFgoodrich All Terrains on my Disco 300 tdi. Gonna replace them with General Grabber ATs very soon I think.

Ah, thats the one I was thinking of. Could only find the other pattern so thought it was that, but different due to a thinner tyre. Report I saw was on a D3 with em. Peeps in the press have independently said they were good, but just wanted owner opinion. Thanks.
 
They are good but still managed to end up spending 5 hours stuck in a ditch. :doh:

It got to the point where I became paranoid about ripping the entire exhaust off again (which wasn't caused by the ditch incident) and it just made off roading no fun at all so I ended up getting a much older disco but I guess that's not for this thread. :p

Firstly, thanks guys for all the information.

However, I have Goodride SV308's on the front, it's the spare that's a Maxxis! (Don't I feel a dummy?)

So, from what you guys have said, seems the cheaper answer for me is to buy three more Goodride SV308's to fit to the other three wheels, with the newer rubber at the back.

I can't afford to go barmy with the tyres just yet, but equally can't afford to screw up the other components detailed as 'under threat' from a tyre mis-match.

I'll be back with the next request for help soon...

Hi sounds like a plan to me !:)
 
Take the prop off (easier to remove both props and vcu at the same time) and tell your insurance, as a quick fix untill you get the tyres sorted.
