Tyres for our uprate

@jim and pat dalton
Did you get your tyres sorted, if not it might be sensible not to send the paperwork off to the dvla until you have.

The tyres must have a load rating of >50% of the axles plated weight for a single wheel axle irrespective of actual payload.
When I uplated my Crafter Dee Thorne specifically asked for photos of the rear tyres before sending me the doc pack I guess he likes to ensure the vehicle are legal beforehand!

It is one of the things that regularly gets checked if stopped at a police or DVSA checkpoint

My Crafter rear axle is plated at 2400kg hence typical dual rated 112/115 van tyres cover it as a 115 rating is 1215kg per corner for a single tyre axle

If my crafter was a dually then the lower 112 rating would have applied x4 so the rear axle could have been plated at 4480kg on the same tyres

Thanks for that info, nicely detailed and useful. I had the air suspension fitted by AS-Airsuspensions the previous week (whilst I played a round of golf at the nearby course) and the tyres changed (112 load rating) by my local garage this week whilst also having the van completely checked over for our forthcoming trip to Morocco on Nov 11th . Ive given the tyres (which were all really good) to the person that bought our old van, so they will not be wasted.

So I will contact SVtech and start the replating exercise next week.

Reading this has reminded me of something that I need to address.
I’ve already had 225x15 tyres fitted to my existing 215 rims.,The ride quality seems to have improved, as does road holding.
Several people have commented on, perhaps my tyre pressures were low.
Checking them, they’ve always been within a couple of psi of the standard recommendation.
I’m wondering if, because of the greater volume of the tyre, I should increase the pressure by,say another 5 psi?

No, bigger tyres mean lower pressure.

Basically, you need to get the axle weighed with the van fully loaded. Then look at the load rating and max pressure. The correct pressure is proportionate.

Thats interesting to know 116 to 118 makes a difference

If the LR goes up, the pressure can go down.

Increasing the load rating from 1250 to 1320 (assuming the load was 1000 and the 'max pressure' is 65) means you can reduce the pressure from 52psi to 49psi
