since 2006 ( I think ! )
Some may be aware that this year I have been involved with tyre tests for my motorhome
It all started when I tried to get a pair of Hankooks, but soon found out they were no longer available in the UK in the spec I was looking for
I tried all sorts of makes ( wellllll, given the cost to me was the price of diesel to a tyre fitter it would be rude not to :-) )
Tyre size used are 225/75/R16C
Plated weight of vehicle 5.25t
Tested on various roads and conditions and also firm grassed areas in wet and dry conditions

I am not going to 'slag off' any particular make except for one.. Michelin Camper Tyres were plain horrible.
They were the noisiest, the harshest ride, the worst grip under certain conditions and the most expensive

Other well known makes tried included Avon and Continental, plus there was a couple of oddball ones thrown in the mix as budget end examples

The very last tyres to go on were Davanti DX440's ( as an aside they are also marked up as mud and snow tyres )

As soon as they went on the sound level was noticeably lower.. About the same level as the Hankooks gave
We have done approx 4500 miles on them so far .. I would like to comment on the wear rate, but so far there is none determinable, so other than saying it appears to be very good I have little to add

Grip level is little short of amazing.. Such things are hard to judge under normal road use, as I, like most motorhome users tend not to drive the van like I stole it :-)
But off road.. Perfect. They are equal or better than even the Hankooks which I raved about for ages.
These last few months have not exactly been arid, and as is the lot of motorhomers ( probably world wide ) we have found our selves in a few soggy, rutted fields.
Not once did I find myself wondering where the nearest tractor was ... Yes, the tyres slipped, but just like the Hankooks, 2nd gear and tickover saw the tyres wade through the goo and dig us out of the goop

All very nice, but now the most surprising result..

It was not on the test list so I never gave it much thought .. until on the way home from Birmingham on Wednesday
For some time I had noticed our fuel consumption was way off. As long as we have owned the van it has not been great.
When I first got it the average was 19 mpg.
I bought a plug in box box from Torquing of Diesels, and with a couple of phone calls re setting it up for best economy saw the average mpg rise to 21.5 .. Not staggering, but given the miles we do, and the fact most of the time we are fully freighted, I was content.

Over the last couple of months economy suddenly shot up to 25.4 MPG
I racked by brains trying to figure out what I was doing that could give such a big jump
It was not until last Wednesday that it dawned on me.. The tyres.
They are the only thing that has been changed.. Now I know that tyres can and do make a difference, but the increase in economy has left me Ghast well and truly flabbered :-)

So for me, the Davanti offerings are hence forth top of the list.. Oh, and as yet another bonus... they were actually on the list as a middle range economy priced tyre
Retail at about £70 a go

Totally agree looking at swapping mine before they are worn out. Spin even on tarmac in the dry.
On the last van I changed the Conti's for Hankook 4 season they were very noisy for the first 500 miles then they quietened down but I was not that impressed with the grip.
Thinking about Toyo HO9's for this van just need to make sure winter tyres are legal in summer in the countries we go to.

Why wouldn’t they be?? They are standard factory fit on some Peugeot suvs, 2008 for one??
 
cant find a uk dealer
 
Useful info from Jaws. My experience of Avon van tyres (fronts only) was OK until very low temperatures when they had noticeably poor grip, compared with previous Michelins or Conti Vanco summer tyres neither of which were standout performers anyway but felt more secure. Not a scientific comparison, just my 2d worth.

The reason they were added was personal .. They were not on the list originally but as I already had them fitted it seemed silly to ignore them
I found them a little noisy ( no where near as bad as Mich;s ) and I had noticed some wall cracking after only a year.. which was what started the whole thing off and me searching round for replacements.
Avon do not recommend their tyres are used for motorhomes even though they are spec;d correctly
 
Jaws We had to have a new rear tyre fitted on Tuesday and replaced the other side too, within minutes of being on the road again (thankyou Rac man and Steve the tyre man) it seemed much smoother and quieter and by the end of the journey we had gone from doing just over 20mpg (average over last couple of months) to well over 25mpg- well chuffed we were!
Not sure of the make and he who must not be disturbed is watching rugby but will send him out to check later.

Do Davanti have a model number?
Quick search finds DX440? I trust your assessment but websites show wet and economy as only C and C and so on first glance I would have skipped these tyres?

The tyres are marked as DX440 as per the info in the OP :)
 
Just fitted a set of Hankook's and hoping they are as good as you say. (y)
What size ? Surely not 225 75 16 ?
If they are, please let me know where you got them from

Doh! ?. Should have looked closer.
Strange how the scoring system doesn't relate to your excellent review and experience in the real world.

Here's 225/75 R16's if your looking for them.



I was coming from Continental Vanco Camper 215 70r15 tyres, so to keep roughly the same tyre height and speedo accuracy I went for the Hankook Vantra LT RA18 225/65 R16C which are 17mm larger in diameter which has helped to bring the speedo nearer to true road speeds.

I got mine online from 123tyres.co.uk at £81.73 a pop delivered. (I see the price has changed as the come from Germany and exchange rate play's it part)

Used one of the online traders to buy some Toyo H09's last year, they were delivered from Slovakia and were 3 months old.
 
Can anyone tell me the difference between the Q and R ratings? I have Agrilis 225/75/16 with a 116q rating.

Are the Hankooks above the ones that many have recommended? (Hankook Vantra LT RA18 225/65 R16C )

Can someone confirm which Davanti DX440 tyres are being referred to or is this the full mode name?

My Agrils tyres have done 32K miles, were swapped front to back and now have 5mm across the fronts and 4 across the backs. Run them at 80psi as recommended by Hymer (3.5 ton A class) ride is quite hard but very happy with wear rate, braking and noise but unlike the OP, do not have anything to com[pare them with.

They are max speed rating, Q is 99 mph and R is 106 mph. (99 or 106 mph, you wish)

Don't know as I researched and bought the ones to suit my needs. Do a forum search for Hankook tyres and that should bring up what your looking for.
 
The Michelin Agilis with the snowflake symbol are Cross Climates which have pretty good reviews as car and commercial tyres and come in the 121 load rating. Michelin however were insistent they were not suitable for motorhomes, they are apparently bringing out a new “camper” tyre but had no timescale. Continental had a completely different attitude and just said use what they sell. I’m sure both are much of a muchness
 
I've been quoted £90 fitted each for the Davinti tyres by a local Tyre company today - where might I look to get them at a lower price as the OP seemed to think they were cheaper ?

Well you could try where Maz has gone in Peterborough, or where I mentioned here in Thetford ?
 
I think you've got to be cautious of MPG readings across tyres, a slightly smaller rolling radius makes the speedo read more miles, and higher speed! If you are spoofed into thinking your doing 62MPH when you are actually doing 60MPH you naturally drive slightly slower. Hence a double whammy, you think you've gone further and you have driven slower. Then lo and behold you are spoofed into thinking your MPG has soared.

The factors that make a real difference in MPG are the flex in the walls and tyre width rolling resistance is usually reduced by stiffer tyres and narrower profile. Neither of which bode well for grip and stopping distance.

In the industry HORIBA MIRA Ltd are probably the only people who I would trust to give anything more accurate than purely subjective analysis.

After my current experience of Michelin Camping tyres on this van I never want to see a Michelin tyre again. Don't think I've ever come across tyres with such a low grip level. My front wheel can spin on dry tarmac and I have a reasonable front axle loading of 1950 kg.

I use the GPS for mileage and how much goes in to the tank to work out gas miles

I got similar information from Michelin recently, which is due to the tyre not liking sitting around doing nothing for long periods at a time.
As my van is my only vehicle and is on the road pretty much every day, I decided to try the Crossclimates anyway and so far I’m liking them.

I am (well the motorhome actually!!) Currently on R235/65 R-16 Continental Camper Tyres. It`s a size that seems to be "difficult" to come across?.

Not exactly common !

Likewise van in use almost daily. Mainly down to lack of wet grip, I replaced the Agilis with Cross Climates at the front. They've already done 3.5k but where we've been did not need the wet grip anyway. My main concern was the noise aspect owing to the block tread pattern. They seemed very quiet initially except for smooth hot tar roads where they whined a little, but they do seem to have increased in noise a little as they bed in, which seems counter-intuitive. But generally not a problem. Happy with choice.

We have the Toyo H09 excellent tyres, great grip in all conditions can't see much wear after 6000

Have you got recommended pressures for the Davanti tyres please? Front axle loading around 1900kg.
