Technical Doblo Tyre Wear

No, it will pass with these tyres, reason being...

Maximum front axle weight: 1ton
Maximum weight per tyre at 84T Half a ton (or 500kg)

Thus it will support the weight of the axle and it's load. The problem is, without the tyres being reinforced, or being of a higher weight, when you corner and the weight transfers to one side of the axle then this could overload the tyre. However it's unlikely that with just the engine etc and a few passengers will take the front axle load up to a Ton. Also bear in mind the weight shift when your braking... Yep it's on the front tyres as the weight shifts forward, thus increasing and possibly overloading the tyres.

What you have is llegal, it's just the minimum you could possibly have on the front axle. The back axle needs at least 88T to be legal I think!
 
Pump them up a bit then :p especially the fronts as they're carrying the weight of the engine. You should see an improvement in MPG too with pressures that low!
 
ref your tyre wear i have just put on the third set of tyres at 34k miles due to the inside edges wearing excessively. had 4 wheel laser tracking check and one comment was they suspected excessive camber. the i.9jtd should have around 3degrees (this itself is quite high) but suspect it is greater than that. i am due a service this month so will get main dealer to also check. i have fitted goodyear gt2 as supplied with 88 t rating
 
Ok well a bit of an update... 2500 miles on and my lovely Pirelli P3000's are looking just as good as new :D

Plenty of tread left, much better handling especially in the wet too so that £100 was well spent :) trouble is, I said that when they go next I'll get myself some alloys, but it doesn't look like that'll be happening for a while now ;)
 
Had similar 13000 miles out of my first 2 sets of tyres. eventually garage sent dobby off to alignment specialist after i complained to Fiat directly. last set 2000 still ok
 
Hi everyone I'm new to the forum, I got my doblo cargo in april, it had 4 quite new tyres on it, after 35,000 miles in 5 months the back tyres still have about 4mm left on them and the fronts had to be changed after about 24,000miles of me having it ,thats mostly motorway miles , the van has done 94,500 miles since new

Welcome mack, your tyre wear seems average for the Doblo.
 
Welcome to the Forum Mack (y)

This tyre wear is ok, but stick some Pirelli P3000's on there as another member NiallG had about 60,000 out of his fronts - motorway mileage - on these tyres.
 
I have had 4 sets of tyes in 12 months !! not cheap ones, always mid range or the most expensive.
Im so fed up with changing my tyres because the inside edge has worn to the limit while the rest of the tire is untouched.
In desperation and at kwik fits recommendation i had van tyres put on mid january. Guess what - they are now illegal.

I do 250 miles a week commuting to work. I'm a woman and drive like a granny.

I have seen on this thread that some of you recommend higher tyre pressures, i think we have ours at 30psi? is it really ok/safe to run the car with higher pressures at the front and will that increase the tyre life?

I have the tracking checked every time i have the tyres changed, its always pefect

your advise will be appreciated

Are you sure the tracking etc. is correct?
I do the same mileage and need a pair of new tyres (cheap) about every twelve - fourteen months. I always do the tracking/balance etc. as well, and I drive decently fast too.
But: I go really slowly over speed bumps, and avoid them wherever possible.
 
I think they are a bit heavy on front tyres,i checked mine at the weekend and ive done 11k since i brought it last july,and theyre not far off being in the bin,inside or any edge wearing does normaly mean tracking but from owning an alfa 156 and having the tracking set proppa they still wear on the inside so maybee the Dobbies are the same,carnt fault the handling for a van though.

id just try and get the tracking checked at another tyre place just to be sure,some places do it for free if it doesnt need adjusting.

hope this helps

I bought my Doblo 1.9jdt with 8k+ miles on the clock and had to replace the fronts at just under 20k due to severe wear to inside edge. Thinking this prob was down to tracking I asked the fitter to re-track all wheels on electronic tracking system. After 5mins or so he said he was unable to correct the tracking and told me to return the car to the Fiat dealer. Almost without hesitation they replaced both front springs and after a bit of row Fiat gave me coupons to the value of £100.

The car has now done 160K with the last set of fronts lasting about 5k due to excessive wear to the inside edge. I've swapped backs to fronts but, do I buy another pair of new springs/get retracked before these get scrubbed out.
 
Firstly; Don't fit a tyre with a load rating of less than 88 to a Doblo. This is the Fiat (minimum) specification, so anything less WILL invalidate your insurance, in the same way that using a speed rating lower than T would.

Secondly; Manufacturers RECOMMENDED pressures are exactly that. I wouldn't suggest using lower pressures (other than in extreme conditions) and you should certainly never exceed the maximum inflation pressure stated on the sidewall of the tyre.

We run 40psi front and 44psi rear on our Dobby, (a 2002, 1.9jtd elx) and this has proved to give reasonable tyre wear, plus better MPG. The tyres do still tend to wear slightly more toward the inner edges, but it is not bad and I compensate for this by turning them on the rims, if required, before they are half worn. (I do my own fitting, so there is no additional expense.)

I have tried various brands, depending on what was on offer and Pirelli "L6" has been notably good most of the year, with Marangoni "Winter4" doing a grand job in the colder months. Next spring some Avon "ZT5"s will be going on, as they are quite well discounted at the mo.:)

Sorry for the ramble. Hope you find the above helpful.:wave:
 
Like a man with a sense of humor.
All ways have track done with 4 wheel alignment the things are hard on tires you either live with it or find another vehicle, shame it is so good in some ways.
I could get higher miles in the old Mini pick up with over 100 HP on tap & being 40 years younger :D
 
Seems we has us-selves a problems folks :bang:

I had a 2002 Renault Laguna with a similar problem, albeit in the rear section!

I ended up undoing the rear lower hub bolts, slackening the top ones and fitting washers into the lower bolts.

The effect was to adjust the camber of the rear suspension.

Formerly I managed around 5 to 8k on rear tyres, after adjustment, I got 15,000.

No more inner wear.

I will look into the problem with the front wheels, but I imagine it is a caster problem which is more complicated.....(n)
 
The problem could be Castor but much more likely to be Camber, my feeling is to much compliance in rubber bushes, would try polly bushes if I was going to keep the thing, on ours camber on alignment is Just within tolerance but not good, castor same, playing with toe in\out helps but not a cure.
This appear to be a problem with a lot of newer vehicles, talking to a Peugeot tech who said some models are real bad.
4 wheel alignment will give definitive result regarding measurements if the operator is up to speed & equipment in calibration.
