Dis binne kort tyd om nuwe tekkies vir Bomber te koop en ontslae teraak van daai marie biscuit wiele wat hy op het. Ek weet nogie watse brand of grote nie maar weet net dit gaan bietjie groter bietjie breer wees.
Nou is my vraag indien ek groter gaan, gaan dit die spoed leessing affekteer. Kan mens die speedo her kalibreer om die nuwe band grote te match?

Re: Tyre Size vs Speedometer
rule of thumb - speedos over read met omtrent 5%.
En die manne sê mens noenie meer as 3% groter gaan op die wiele nie - dan moet jy begin kyk na remme en n paar ander goed ....
so as jy nie "way out" gaan met die bande nie, dan behoort die speedo net mooi reg te lees :)

Re: Tyre Size vs Speedometer
Ek het verander na 31x10.5x15 op my SFA . My speedo lesing is nou dieselfde as die gps maar die km lesing lees nou minder as die gps.

Re: Tyre Size vs Speedometer
Ek dink ook 31" is die magic nommer as jy overlanding doen en so paar rowwe roetes. Met my 2.7 het ek ook nie die verskil in krag agtergekom tussen 30 en 31" nie. Die speedo is effe meer akkuraat. Die 31's is groot verbetering van standaard grootte.
Het die naweek sowat 400km met my nuwe Cooper ST Maxx deur die Cederberge gery en ek is baie gelukkig. Die trokkie sit weer soos bollie aan 'n wol kombers op die grodpad. Hulle is ook lekker stil op die teerpad, glad nie meer so raserig soos die ou Coopers nie.
Gaan vir 31" Cooper ST Maxx.

Re: Tyre Size vs Speedometer
Louis ek het nou 1 size opgegaan op die Driepoot-Broodblik na 265/75x16 toe. Die speedo is nou meer akkuraat, op 120km/h is hy nie meer 10km/h uit nie maar 7... 
My raad sal wees as jy ne HOEF 16" rims te gebruik nie, gaan na 15" toe, en sit 32" tyres op soos Ciske op sy Hilux gedoen het. Jy sal net moet seker maak die voorste veringspacers is ingesit, anders kan (mag) die wiele dalk skuur.

Re: Tyre Size vs Speedometer
I have 31's on the SFA and the speedo is almost spot on with the GPS - 100 km/h on the speedo reads at 101 km/h on the GPS. The odometer however under reads by about 5% against the GPS.

Re: Tyre Size vs Speedometer
Louis. If it's for your 2,5 D-4D, then 245x75x16 is very close to the standard circumference. If your 2011 is as underpowered as my 2007 2,5 then it will battle to pull anything bigger, profile or width. Put in a chip and it'll pull 265x75x16. I doubt 15 inch wheels will fit over the disc calipers.

Re: Tyre Size vs Speedometer
Correction that should read 245x70x16 not 245x75x16.
