I'm looking to buy a new tire for my M/home, max weight 5 1//2 ton loaded. The Michelins that are on don't have the ply rating on them.

All it says is 225/75 16 CP XC CAMPING Tread 2 polyester + 3 Steel. Sidewall 2 Polyester. Anyone know if this is a 8 or 10 ply rated tyre.

i'm not sure what one to get? as the dealers I've rang didn't know and said buy a budget tyre.

Many thanks Graham.
 
The only correct starting point for your search is the local weighbridge.

Once you know which axle is carrying the most weight and added an allowance for side to side imbalance, say 10% extra - and your vehicle needs to be fully loaded for a trip and have the co-pilot in it as well - then, and only then, can you start looking for a tyre rated to carry the load.

Believe me it is on there! it will be a three digit number. On the 15" tyre it is 109 on your 16" it could be 112 or higher and that is the load index rating

EDIT Actually 16" will be 116 or 118

AGILIS

EDIT again. Wikipedia tells me a 116 load index is worth 1250kg so that's 2.5 ton per axle

Is your rear a 4 wheeler or tag?

Tread 2 polyester + 3 Steel. Sidewall 2 Polyester.


that is the number of plys actually in the tyre. under the tread theres 2 layers of polyester and 3 of wire. sidewalls dont have the wire.

probably youre best bet is to take the vehicle to youre nearest ats or any chain except qwikfit. and ask their advise... they will be able to match youre existing tyres with an equivelent..... or tell you theyre all wrong uns.
 
Without knowing the individual axle max. weights, it is difficult to say.

The Michelin Agilis camping tyre is rated at 111/113 and I was told that they are working at nearly their maximum weight on the 2 ton front axle on my tag axle van. If the axle is overloaded (very easy to do on a tag axle van), then the tyres are also overloaded.

i needed a tyre as a spare and the same chap recommended a 16" Mohawk tyre (which I bought) at a good price (around £75 to £80 from memory). It is a higher ply than the Michelin and is rated at 112/114. It has a good tread pattern and should be better on grass as well.
 
Thanks one and all for your help. I have nailed it down to Being a 116 Q tyre. I followed Techno's advice that it was there somewhere, and found I was reading it as 1160. Hence no three digit code. The M/Home is a tag Burstner i821, these replies have shown me how important getting the right load rateing can be. I have a friend at present who has had his insurance cancelled after an expensive accident and five months in hospital, because of a small wrong detail. This will wipe him out financially, and result with five court cases at the moment pending. Including one for his wife for lending him her car. His last words to me where, What are the chances of anything hapening, So now armed with these new reference changes, and never considering the forward load increase on the front tyres when breaking before. Its the right tyres or nothing from now on. Incidentally the tyres have done 11,500 miles from new, and the front are just above the pip mark in the tyre tread. All that remains is to get a good deal now, so back to the net. Many thanks once again, Graham.
 
I am puzzled by your 5.5 ton remark in your opening post.

Without googling (I am in the middle of a farmers field) I would have said your Burstner would be the same as my 747.

ie: 2 ton front axle limit and 1.5 ton on each rear axle. Have you been looking at the last weight figure given on the plate? As far as I am aware, 2 ton is the maximum a Ducato can go to on the front axle and that is with special longer, heavier duty coil springs fitted.

I would check again just to be certain, it might save you some money.

Hi maingate, Iv'e taken a shot of the weight plate on the outside of the M/h.
I think you are nearer the mark than me as I had been told the info by someone at a show.
I still don't understand the top two amounts, 5000 and 6000kg? as they are unmarked

Anyway here it is below, and thanks for your help.

Rgd's Graham.
 
hi
5000kg gvw
6000kg train weight
then first .axle etc
not alot of a trailer you can tow behind that one.
infact not alot of leeway on any of the axle weights as to the gvw.
 
Your front axle is 2100 Kg which is 100 Kg more than mine and I am mildly surprised as I thought 2000 was the max.

That extra 100 might just make the difference by ruling out the Michelin Agilis 16" camping tyre.

If i was you, I would get your van on to a weighbridge in running trim and see what weight you have on the front axle. Tag axles are usually close to the limit on the front and have plenty to spare on the rear 2 axles. You might need to store your heavier kit towards the rear to take weight off your front end.

Mine is close to the limit and if I carried 4 belted adults, full water and fuel tanks, I would be a long, long way over the axle loading. I have a lot of weight at the front and dangerously, it is all on the UK nearside (water, fuel, gas, waste tank and leisure batteries). So much for German engineering. :sad: If I ever have a blowout, it will be my front nearside tyre that goes.

An email to Michelin with the details would be the best way to go but you would need to tell them your actual axle loadings (hence the need for a weighbridge). Good luck anyway.

Thats shocking for professional and well respected converters. Even on my home conversion I'm taking all weights of major items into account and balancing either side and front / rear, on a much smaller 3.5t panel van mind.
