What Size Off Road 4x4 Tyres Do I Need For my Ducato Motorhome? (Tutorial, Pros & Cons) 

You will find the 70 is not the actual height of the tyre in mm but the ratio to the width of the tyre. So in this tyre the height of the tyre is 70% of 215

Tyre load rating have to match the maximum axle load on the Vin plate or you are illegal if stopped and checked and you can't just take maximum gross weight and divide by four as vehicles carry most weight on the rear axle . Check the manufactures vin plate for four weights .

Hi good vid thanks. I am guessing all that applies to a 2017 Peugeot Boxer? What do you do about a spare. Can it still go underneath or would it need to be door mounted? Thanks

Useful video. I went for 225/75-16 up from the 215/70-15 inch from standard increasing the gearing by 9%. I fitted Falcon Wildpeak AT3 which are snow rated (3 peak snowflake symbol) so comply with alpine regulations, unlike mud and snow tyres which are not recognised in Germany. Rides better, better traction, no negative impact on performance… oh and they look ace!

Hi... My Ducato tyre size rating is 16/14. The only All Terrains that are suitable are size 15. My insurance company says need to stick to manufacturer's rating, even though the rating is for commercial tyres. What do you recommend.

You missed some important points. You might only do 60mph, but your braking distance will be much longer, especially in the wet. Big heavy van can be difficult to stop on standard spec tyres. If you carry a spare, fair enough, but many ditch the spare as its dead weight, but if you go for anything none spec, you could be waiting around for a very long time. Most EU countries will not fit an individual tyre, they only fit in pairs. This could be a huge problem. The next thing is that a bigger tyre weighs more, is harder on the engine and clutch to turn said tyre. Remember, the vehicle was designed for a 15" wheel, although campervan manufactures like 16". Most big treaded tyres won't actually wear out. They are much more likely to getting past their use by date. I am thinking about ATT's, but common sanse says no. I'm also thinking about getting rid of the spare.

Great review would like to add I have just put Yokahma g015 geolander tyres on 225/75 r16 115 fantastic looking tyres with great road handling, road noise no different, ride is very good, but more important to me the tyre loading is the best around they are 10ply tyres along with the 3 peaks winter rating and cheaper than BFG

Doesn't increasing the overall height of your tyre and wheel combo mess with your speedo?

Remember that the weight changes when cornering. Then one tyre can have more than1000kg and other less than 600kg. At the moment Im running 235 55 19 with load rating of 105 . But I am after 235 65 17 108 all terrain as I had those before last year. And yes I wish I could drop the front a bit to hide the gaps 😜

Just put BFG KO2s on ours. Our mpg has dropped from 29.9 to 27.3 but the ride is 100 times better than the CP rated tyres.

Hi, nice overview, thanks for that I'm currently looking at BFG AT/KO2 tyres for my Movano. A quick question for you: Did you notice any reduction of torque due to the changed transmission ratio with your bigger wheels? Also just a note, I'm not living in the UK so things may be different but my understanding is that your tyre load rating needs to be at least half the load rating of the axle they're on. As well as the tyre's speed rating needs to be at least the vehicles maximum speed (according to the papers) although that may be different for M&S tyres. thanks!

Have you recallabrated your speedometer as your tyre is a larger diameter, your Speedo will display a lower speed, and will record a lower mileage (which will give inacurrate mpg). You should aim for the same circumference of the tyre when changing sizes.

You say the tires you have fitted will hold up to just over 4000 kg ,that is only at maximum pressure ,which on your tire I believe is 69 psi .you're currently running at 55 psi which means the sidewall will create a lot more rolling resistance making more heat and the tire is more likely to fail , Campervan tires are a 10 ply tire on the side wall it will say 10 PR And will hold up to 1380 kg per tire your new tires are probably only eight ply possibly six they are 10 ply for a reason take care and be safe

think your speedo will be out now as your tyre size has changed?

As always..👍👍 oh and I think you You meant to say by 10mm not 10cm..lol

Your front wheel arches cannot be as small as the rear ones because your front tyres have to turn :D

The profile is 70% if the width of 215 not 70mm.

Actually, you're out of the technical limitation for the tyres. Fiat specifies that you can only mount 215/70 or 215/75 with 15" wheels. This is why you have only such a small space with the rear wheel archs.

Im sorry but I think the new tyres are underated for weight capacity and not likely compliant with the plated spec axle wise. Plus the speedometer and mileometer will be quite inaccurate.

Just a heads up for anyone so they aren't misled.. He didn't "increase by 10cm" as he said.. He didn't even increase by 10mm (which is what I assume he meant) because he got it wrong when saying the second number represents "70mm" "80mm" etc. It doesn't. It represents the % of the tyres width. Ie. 235/70/16 would have a higher sidewall than 215/70/r16.

Do you realy like your music?

Woah 102 rating is definitely not enough on these vans you have that wrong unfortunately! The rating required is based on max axle weight not the actual weight of van and conversion. The front axle of these vans is rated to 1870kg meaning you require at least a 106 for the front. The rear is rated to 2000kg meaning you need a 108 on there as a minimum. Those two numbers don’t add up to 3500kg which is you GVW I know but that’s how it’s done! Please correct this as it’s very dangerous!

Sorry but can not see this,with brain cancer creatief noise
