Kan wen van die manne wat meer van tyres as ek weet vir my se wat is die alternatiewe grootte op 'n 31x10.5x15 band grootte. Is dit dieselfde as n 255x70x15? Ek kyk na ander tipe bande v my trokkie en hul kon my nie help in die 31 groottes en hul was self nie helemal seker of die twee groottes dieselfde is nie.

265 x 75 x 15

15 inch rim x 25.4 gives you rim size in mm
31 inch tyre x 25.4 gives you tyre size.
The 255 is the width of the tyre and the 70 stands for 70% of the with.
So add the 15 inch plus 70% of the width x2 and you will have tyre height.

31X10.5R15 = 265/75R15

255/70R15 het die selfde omtrek as die 30X9.5R15.

Dankie almal. Het geweet ek gaan vinnig n antwoord kry!!

Nou vir die ander probleem. Die enigste grootte waarin die bande kom waarna ek kyk is die volgende...

Hou ek verby of is die 265/70/15 amper dieselfde. En wat boet ek in??

2 x 265 x .75 + 15 x 25.4 = 778.5mm

2 x 255 x .7 + 15 x 25.4 = 738 mm

2 x 265 x .7 + 15 x 25.4 = 752mm

31 x 25.4 = 787.4 mm

Ja this is quite interesting. Now for the real silly question. Does the 3cm or so larger diameter makes a huge difference other than looks??
There is a huge price difference and I just thought I finally have the thyre I like and can afford just to realise its the wrong size...

Well every little bit helps to get the diffs futher away from the ground.But like you said the bigger you go the more money to be spent,body lift and so forth.........

What brand of tyres are you going for?

Currently considering General Grabbers AT as I can get a real good price on them, but then have to choose between the 255/70/15 and 265/70/15. Since I realised that I cant get the right size in them I am reconsidering the Hankook dynapros but they will cost me the best part of a R1000 per tyre more....for only 1.5cm larger diameter tyres...???
So back to being very confused.

Dankie Johan.
Net om seker te maak ek verstaan jou reg. as ek van die 31x10.5x15 na 265x70x15 gaan dan gaan my bakkie
787.4-752 ~3.5cm laer wees??

Die salesman het gepraat van net1.5cm maar somehow glo ek jou meer :-)

Dit raak n verskil.

Ekt gesien Andre maar dit is net op die 30x9.5x15s...
Die 31s is so R2350 en ek kan grabbers kry vir R1400... Dit bly vir my groot verskil. Kan baie ander goed met daai xtra geldjie doen maar wil nie spuit wees op lang run nie..

Weet nou nue meer watter kant toe nie maar moet binnekort besluit. Of ek moet maar net by die Bfgs bly.

My Hankooks het nou 50,000km op en lyk nog baie goed, het meer as 8mm loopvlak oor, ek is baie tevrede, al nadeel is hulle raas teen lae spoed 60 km en minder.

Kan ook nie dink hulle raas minder as die Bfs nie...of mens moet sorg dat jy nooit onder 60 ry nie :-)
My kop en bank sake staan net nie mooi selfde kant toe op die stadium...

Pieter, ja en nee dit is die wiel se deursnit, die bakkie sal die helfte laer wees. Maar dis die teotiese berekening, daai ouens wat die moulds maak se maatbande is nie altyd heeltemal akkuraat nie of hulle kan nie lekker lees nie, so die fisise mates van elke maak en tyre verskil bietjie teenoor die teoretiese berekeninge. So as jy dit fisies meet of die mates van die vervaardiger kry kan dit dalk effens verkil.

Dankie Toyoda. Dis scary dat die verskil tussen n 31/10.5/15 en n 265/70/15 beteken dat oor n 80 000km tydperk die 265 meer as 1.5miljoen meer revolusie maak as die 31... So die 31 moet net beter kms gee...
