Tyre Loadings

[apole]

Hi guys,

Done some searching on this before posting but still have a question I'm hoping someone can advise on.

I have a V6 bongo AFT, with a full side camper conversion and an additional LPG tank.

With all of that I have no idea how heavy it now is.

Looking for some new tyres and may have found some but they have a max loading of 630KG each. Do you think this is too low?

they need to be rated about 96H or above,some have 94H on but probably best to go to at least 96H if having new tyres. £38 each i paid for mine ,supplied and fitted/balanced, at wheelquick in wigan.

With all of that I have no idea how heavy it now is.

Our conversion weighs about the same a standard Bongo, as it it built from vohringer ply, and has had both rear seats removed. Even fully loaded with water, food and camping bits and pieces, it will never weigh as much as a Bongo with eight adults in with just the two of us in it...

BUT there is an easy way to find out:
Find a public weighbridge and hand over your fiver (well that's how much it costs around here).

My diesel with 8 seats, topbox and paranaphalia (sp) weighs 1930 kg

The simple answer to this is they must be 96 rear 92 front (minimum). This is based on Mazdas max permissible weight which will not have changed no matter what conversion you have.
I agree with trevor in that a full conversion does weigh close to that of a normally equiped bongo - you have less passenger carrying capacity, but are more likely to fill it with kit when you go away.
There are plenty of options to get tyres above the 96 load rating and too risky in my opinion to chance anything less.

Mine has a conversion. A few weeks ago I dropped off a bit of stock at a factory in Manchester. I had to stop at a weighbridge on the way in, sign a book then was allowed through. The scale showed 2240kgs on the way in.

Dropped off two 20 kilo bags of boilersuits then stopped on the scales again to sign out.

2200k.

I know what mine ways now. Cool.

Along the same lines as the thread intended - one (in fact two) of my MOT failures last weekend were down to tyres. Around xmas time, I bought a set of alloys that had two decent tyres & 2 shabby. Kwikfit stuck a pair of 92 index new ones on the front as the back seemed okay. 4 months down the line, the MOT tester pointed out that the entire circumference of both back tyres had split on the wheelarch side.

Never occured to me to check the loading of the old tyres but were in fact 91's. !

Very close call there. If you lot havent had a look yet I pretty much reccommend you do .

Pronto!

Needless to say a nice pair of 96's are shod on the back now. All is well.



Edit: Tyres rated at 96 have a load rating of 750 kilos. (95's are 20k less I believe, etc.). You need these on the back.

92's are fine for the front.

I have seen a lot of tyres (mostly old jap rubbish that has been sat in the sun for too long) split all round the rim.
I have had many others go way out of shape due to bulging and splitting within a few hours of driving in the UK.
Definitely worth a close inspection if you have old or under rated tyres.

Thanks for your help.

Right now I'm good as the tyres I have are very recent and have a rating of over 100, I think 105, bridgestone tyres for a van.

However looking at some alloys, found out from a web search these are 91 and 95 rated, so not good enough. Good to know as the tyres are no use, which has to be factored into the cost.

I think I'll wait a while and get new alloys from Bell Hill garage and use my existing tyres being as they are so new, then I know I'm safe.

Thanks again.
