So went up a size to 225 aspect and 112 load rating ,,I,be done a1000 miles this week on them and noticeably more sure footed,,,

I'm thinking of doing the same, but I'm worried that my rims won't handle the increased width. I read somewhere that the standard (not Maxi) Ducato rim can only handle a maximum of 215, with 195 being the recommended width. What vehicle did you fit the 225's to?

My main reason was the rear load rating is at its limit with 109 load rating (1030kg) on a 215 aspect tyres ,,,, the 112 ratings are way over that ,,,,,
The van came with 215 when new and the tyres had coped fine at 8 year’s old although worn out,,, the 225 tyres are also 7 mm taller helping a little to increase the quite low gearing that theses vans have,,,,,,,,will look in the handbook when I get home and look at the wheel width, be very surprised if a wheel that can fit a 215 won’t take a 225 tyre though

225 section width and 112 load rating suggests 15 inch tyres.

According to Fiat, 6Jx15 wheels fitted to the Ducato can be shod with 215/70R15 tyres or 225/70R15 tyres, which increases the load rating from 109 to 112.

If you want even higher load rating, you'd have to switch to 6Jx16 rims, which can take 215/75R16 or 225/75R16 with load ratings of 116/118 respectively.

Camper tyres have a reduced load rating, so the 225/75R16 CP rated tyre drops back to 116.

Just as an alternative, TOYO have a tyre called Open Country AT2 which, in 225/75/R16 115Q, is suitable for loads up to 1200odd Kg per tyre. They offer a coarser tread for superior traction in slippery conditions, similar to the Cross Climate mentioned, and are substantially cheaper than Michelin.
I have just ordered 4 for my 4.5Ton Fiat Camper. They are legally within the required load carrying capacity.

This "Camper Tyre" business seems to be a way to part people with their hard earned cash, I use my camper all year and have van tyres all round (Maxi chassis) Much cheaper and every bit as good. If you're putting your camperr away why not invest in a few good timber blocks and jack it up and support it? Never found any difference as I live in Ireland where we test wet grip to the extreme!!!!!

Thanks to all who are contributing to this thread. I had hoped to source a 225 x 65 x R15 tyre with a load rating in excess of 109. Actually reducing the wheel diameter slightly would have worked well for me as the 5th gear on my 4 ton Ducato-powered motorhome is a tad high. I would welcome the convenience of being able to change up earlier and staying in top a bit more. Putting a 70 or 75 tyre would mean not being able to change up below 55 or even 60mph.

What engine do you have ? Is it based on an X250 chassis ?
My working van is always at it's max 3.5T limit and also has been known to tow a 3.5T Digger at the same time (off road of course) and has little trouble getting into 5 or 6th at that train weight .... only issue would be that reverse is a little high if backing up a slope at that train weight....this is with 225's fitted .
Wife's camper is just under 3.5 T fully freighted with water in tanks , full fuel tank , Dogs and her luggage ;-) ....it's a job to keep it under 75 on the motorway in 6th ......this is still on 215's and as it's a 2007/8 build has a higher reverse ratio so will try my 225's on it before getting another set .

It's a 1997 2.5 TDI 8140.47R on a 230 chassis (at the front).

Thing is that the 5th gear on this model was apparently something of an afterthought, with insufficient lubrication and a tendency to fail under load. Many people, including myself, have had to get it replaced. Fiat actually revised their oil capacity recommendation in the light of all the trouble, and then issued a statement to the effect that, gosh well, er, you know, this gearbox was never really designed for installation in motorhomes.

I have been advised more than once to only change up when the engine is warm and when the speed is over 50mph. I understand later Ducato's do not suffer from this problem though.

I think they call it 'Discriminatory Pricing'
Like 'Childrens' medicine has been found to be the same stuff as Adult medicine - proven by the product licence number in the small print on the label. Shamefully kids medicine sold at a higher price because they know parents will pay more for their kids medicine than they will pay for their own

The 5th gear issue has been played to death on every forum for Ducatos, It was an external fitment and works fine if treated right, bit extra oil etc. Not sure about the "Not designed for motorhomes " bit, Most campers lead a very sedate life compared to courier/builder vans etc!!!
