Does anyone on here have 15" tyres on their van?
Are you plated at 3200 or 3500?

The 195's are rated same as mine 104/102 so not high enough
They don't do a 205/70 which would be ideal for me
They do a 215 at 109/107 but that,s maxing the width for my rims and about 7mm too big Sad

Looking into Michelin Agilis+ as they don't do a CP in my size

Well I can scrub Michelin off the list, they don't have a tyre to suit my needs
Awaits more replies from Pirelli, Bridgestone and Continental

Yeah!!! Very Happy
Pirelli have replied and they have a tyre that will fit my needs Very Happy

205/70R15 C 106R TL Pirelli Chrono 2

SVTech called today, confirmed that I do need to change the tyres, asked if he knew of any and he told me a lot of the new vans now have 205/70/15 with a load rating of 109 - I can't find them, think he's getting mistaken with 16", do they still put the boxer and fiat on 15's?

Pirelli Chrono 2's will do though, just in the limit with 106 and a diameter within tolerance for the uprate

I've struggled finding tyres to get up to 3500kg lol!
They also asked if I wanted to uprate the rear axle to 2000kg, I declined, I'd never find tyres for that, best I can find is 106's rated for 950kg (1900kg Axle)

I've seen tyres being filled with Nitrogen but I've yet to witness them evacuate the tyre of air before filling.

Hi Ken

We have 15" tyres on our van, they are the original ones and our van is 3500 kgs.

If you want further info, I will have a look at what they are for you.

Thanks Steve,
Did look into 215's but out of spec for mine, had to put 205's on and highest load rating I could find was 106, just enough Cool

OK Helga's tyres have the following information. I only looked at one but am presuming that they are all the same!

MICHELIN X Radial 215/70 R 15 O Max Load Single 1030Kg 2270lbs at 550 Kpa 80 psi Cold + Max Load Dual 975kg 2130lbs 80psi cold.

This makes absolutely no sense to me, but I hope it does to you Ken. Very Happy

Cheryl didn't say she had 80 psi in? She just relayed the info off the tyre wall and 80 psi is the max pressure.
If you have 60 front you must be on 16" wheels? and 65 rear is in FOUR tyres

Not if it is fully laden. A tyre loading is based on it's max pressure.
If you carry less load you have a lower pressure.
If I carried the full 2400kg on my rear axle I would need 80 psi
YOU have 4 tyres on the back

Have a play about with the pressure calculator I posted on here Bob

PS - you will find that something running on twins, the pressure is not that much different from something running on singles, probably 5 to 10 psi

OK guys, just to add to the debate, asked Mick what pressure we have in our tyres and he says 70 psi all round.

70 in the front? now that I would say is too much
What does the calculator I posted say for your weights?

On the tyres I have just had taken off it said " Maximum pressure 70psi - this only applies in south Africa" Don't know where they went to get them put on Laughing

I've just gone through all this Bob and it opened my eyes to what things used to be to what they are now, been in contact with Michelin, Pirelli, Bridgestone and Continental.
Changed loads of wheels/tyres on cars, know (knew) how to calculate what sizes would fit even with changing wheel sizes, you can still do it but with tighter margins, and don't go off the tyre width as definate, a Michelin 205 is actually 217 wide affraid

That's a pretty good calculator Ken
Gives me 61 front 77 rear if fully loaded rear
I actually have 65 75 with 300kg spare at the back so on the side of caution
Cool

And this is how its done

The simple formula they use is
A=B*(C/D)^1,25
A = the pressure you want to know
B= The reference pressure of the tire( on the sidewall At 250kPa for normal car tires 290kPa(2,9bar) for XL extra load tires, and C-tires mostly 450kPa)
C= the actual weigt on the tire
D = the maximum load of the tire ( load index or in KG or LBS on sidewal )
^1,25 is a bit difficult 4^2 is 16 means square 4 , there is a tab for on jour calculator X^Y.
To calculate back to the weigt the formula is
C= D( A/B)^0,8.

Simples lol!
