they have a max pressure of 44psi

never had car tyres on the van bit concerened as ive allways had 8 ply tyres on the van not a speed merchant steady 60 to 65 on motorway up to 75 80 to overtake

Be careful about running car tyres on a van, your insurance company might kick up a stink if anything happens and not pay out, imho car tyres are for cars, they are not for vans.
But I'm sure someone will say they are ok though.

I think there are those who run car tyres, Simon brickyard was suggesting van tyres were dangerous in a previous thread.Personally I think tyres have a load index for a reason. http://www.carbibles.com/tyre_bible.html tkae a look here running a fully loaded camper your going to be around 2.5 tonne which is 625 per corner, add 20% margin for safety = 750 which is a LI of 98.
Note that a kosher MoT inspector will fail you if the tyres on your vehicle are not suitably rated for its maximum axle load capacities.

Do I stay with the same pressures as per spec for 205/60x16"

I think a max load of 1580lbs is the minimum for campers

Can we get to the bottom of this.....my van(full camper conversion) has 16" Grannie wheels fitted with 215x55 and 205x55 car tyres with a load rating of 91 and 93 respectively, my question is are they safe or am i risking blowouts or sidewall collapse and what will the insurance make of it in the event of an accident. I'm pretty sure i am not alone on this one so are all us 'blingers' destined to an untimely death or is it just a case of 'being on the safe side' when it comes to load ratings and we are really quite safe.

If you have an accident that could in any way be attributable to the tyres and they do not have a high enough load rating then there is a chance any loss adjuster worth his salt is going to ajust away any payment leaving you with nowt.

Are there no tyres for bling wheels with high enough load ratings? How do Escalades get on?

Post by **shepster** » 13 Mar 2006, 17:13

Excuse my ignorance but whats an Escalade? Also is the overall weight of our vans 2500kg 'bare' or is that with beds/sinks/cookers etc.

Upon looking at the Gross weight and axel weight plate (inside drivers door) mine says gross weight (ie max laden weight) is 2400kg

so me the family and the luggage must not exceed this value.

tyres with a load index of 92 (97 is better) means max load on that tyre is 630kg

add this up (630x4) = 2520kg that exceeds the vans max weight. and thats a good thing OK?

this was a car tyre with 92 load index H rated max psi 44 2 ply

thats too weak for me on corners it would tear itself apart. It needs 8 ply

there are car tyres that fit the criteria at 225 width there is a choice but, will there be enough room? on standard suspension, 10mm spacers, merc ML's

Its not add all tyre weights and see if above max load weight. Its add tyre weights for front axle and see if over and same for rear.

93 is the absoloute minimum rating for the rear of a t25, 91 for front.

Load ratings are not covered on class 4 MOT's, all t25's are class 4

An insurance company won't weigh it unless its obvisious it way over weight, they will just use load rating off tyre and max axle weight off vin plate.
