Weet jy wat jou offset is? Moes jy spacers ook in sit?
Nope - geen spacers nie!
Ek sal kyk of die offset iewers op die rim ge-tjap is....

Dankie Christo

Sulke groot bande ry met laer druk as laer profiel bande. Myne werk lekker op 2 bar, of dalk op na 2.2 bar as ek swaar laai & snelweg ry.
... en 4 x 1 ton = 4 ton - heelwat meer as die bruto gewig van 'n Patrol!
Maar 2.2 bar is klaar meer as 30 psi, so jy is amper by die veilige limiet.
Meeste ouens wat laaistelsels agter in het en n dakrak gaan by die 2 ton agter wees, weer by die veilige limiet.
Ek dink net jy moet baie seker maak van die bande se veilige limiete veral wanneer jy 15" gebruik

It seems that pretty much all the 33/12.5r15 tyres speed and load rating is 108Q
108 = 1000kg per tyre
Q = max 160km/h
(according to errolstyres.co.za)
And according to tiresize.com, most(or all?) 33/12.5r15 tyre's LT Load ranges are "C", which equals 50PSI.

on closer inspection, it appears that most 33/12.5r15 max safe pressure is actually
35psi and not 50psi.
(was looking at the "C" rating which is suppose to equal 50, but looking at each tyres individual rating for example:
https://tiresize.com/tires/BFGoodrich/M ... TA-KM2.htm, it indicates 35psi and not 50psi.

So does that mean that you cant inflate a 33/12.5r15 to more than 2.4bar?

Never taken them above 2.4 bar though - I like my spine in one piece and my teeth inside my mouth...

It seems that all the 33/12.5r15's are max 35PSI.
On my 16" tyres (255/85r16), I usually inflate them to 2.5 - 3.0 bar depending on the load. And they are comfortable at these pressures.
(They are rated max 80psi, same as 285/75r16. )

Ok so I have done quite a bit of reading on the net and more people are in favor of using 8j rims with 33x12.5x15 as apposed to 10j rims.
Reason being that the sidewall is more protected (I think Peter mentioned this) and also you can run the tyres more deflated without it de-beading.
I have sort of made up my mind and found a set of 8j rims that fit and my General Grabber MT tyres are on their way.
I don't think its the best tyre on the market, but it at least sports a 3 ply sidewall and 16mm tread. It does unfortunately not have white writing on the side which I think looks very cool.
Best part is the price, but hopefully its not one of those "goedkoop koop is duur koop" scenarios....
Any opinions on this?
