  • Prado Rim Size & Offset Database

    The following is a listing of the wheel sizes that comes standad for the Prado; other vehicle makes with the same stud pattern; and wheels from 3rd party manufacturers. It was compiled to assist other Prado owners in wheel selection.

    The following list only includes 6 stud on 139.7mm PCD wheels. Bear in mind that some vehicle makes may have a smaller or larger centre bore and therefore will not fit on the Prado.

    To use this list successfully, you need to do the following:
    1. Look up the wheel size and offset for your current vehicle. (note: If you have a GX or Standard Prado, you can change to wider wheels. In this case, use the next model up as a point of reference.)
    2. Look down the list and find the wheel(s) with the same offset or lower.
    3. The wheel diameter and width is then up to you. There are various things to consider when choosing diameter and width, so I won't go further into this here.
    4. Make sure you double check with the tyre shop or search through Pradopoint for other members who have successfully made a swap.

    The list is currently incomplete. Please advise if you have something to add (including any corrections) and I will maintain this first post.

    And if you are contemplating fitting wider tyres, refer to this article

    Some fitment notes and guide:
    • A 16" rim can't fit onto a 120 due to interference with the front brake calipers. However, it can fit on the rear of the 120.
    • It is illegal to reduce the track of a vehicle. Therefore, you can't fit a 120 GXL alloy onto a 150.
    • On the 150, you can change the VX/Kakadu 18" rim to the GXL 17" rim. Speedy Avalanche 17x7.5 also fit. viewtopic.php?f=55&t=12335&start=0&st=0&sk=t&sd=a

    The 1st thing to look at is the offset as this will determine your wheel track. Do not go for more positive offset as that will reduce your wheel track. Go for lesser offset.

    2nd thing is to look at how much further out the outside face of the rim is compared to factory spec. To do this, you need the following equation:

    Protrusion outside face of rim = 25.4 x (Wnew - Wfactory)/2 + (OSfactory - OSnew)

    Where:
    W = rim width in inches
    OS =
    offset in mm
    Result of the equation is in mm

    The 3rd thing is to check clearance to the UCA. To do this, you need the following equation:
    Reduction of clearance to UCA = -[25.4 x (Wnew - Wfactory)/2 - (OSfactory - OSnew)]

    If result is +ve, there is an increase in clearance

    I have an Excel spreadsheet I can email you. Send me an email to amtsprado at gmail dot com.

    Or use this excellent calculator.
    http://www.rimsntires.com/specs.jsp

    Some rims from the US only lists backspacing instead of offset. This is what backspace is in relation to rim width and offset. Note that rim width is measured inside the bead. Backspace is measured from outside the bead.

    Re: Prado Rim Size & Offset Database

    I have been advised that the offset on my GXL 150 is ET 10. ET 25 for 120 Prado is confirmed from the same source.

      I am about to buy some steel rims with muddies for my 90 series prado. Could someone tell me what offset i should go to be legal?

      I am getting 265/75r16 maxxis bighorns 762's. With king steel rims. I thought via talk on here that getting 0 offset will be the best but still be legal but two tyre shops have told me that 10 offset is the best and 0 offset will make it hang out the guards?!?!

      if you know anything to help please let me know as i am looking at buying today or tomorrow!

      thanks in advance!

        Re the thread:
        Great idea for a thread, I've often wanted to start one, but I reckon it should be split up by series, and posted into the Tyre section of each series.

        In NSW the max track width increase allowable via rim offset, for an IFS vehicle, is 12.5mm each side - which is a pitiful amount. The original alloys are +15 offset, so +10 is okay and the widest legal is +5 (available, but rare). 0 would be very close but technically a defect. Personally, I don't think it's worth spending money on a set of rims for a LEGAL offset change because the law is too restrictive.

        With the plastic wheel arches I can't see how 0 would would protrude from the body. There definitely more than a 15mm space from what I've seen, try measuring them yourself. For Prado's without flares, sure, it's probably an issue.

        PS: I'd ditch the steel rims idea as well, unless you have a strong case for them. Lightweight alloys are better for suspension response. The only benefit of steel is being able to repair them if they bend.

          one question and maybe a dumb one, but where does back spacing come into it?
          i want to get some dick cepek torque's they are a 17x8.5 and the have a +6mm offset, and 5 for backspacing (no units).

            Backspacing = 0.5 x rim width + offset.

            i want to get some dick cepek torque's they are a 17x8.5 and the have a +6mm offset, and 5 for backspacing (no units).
            I'm assuming that the units for the backspacing is in inches but then it doesn't makes sense as a 17x8.5" ET6 rim has a backspacing of 4.49", not 5". Maybe it's a typo and rounding off will get 4.5" and someone missed the 4. bit.

              Yep, like amts said, backspacing will be 114mm (4.49")

              Backspacing and other terms are explaned here: http://www.customtacos.com/tech/index.php?article=40

              In your case I'll assume you currently have the 18x7.5" wide rims with an offset of +25. If changing to a set of 17x8.5" wide rims with +6 offset, your first concern should be whether the smaller diameter rim will hit your brake calipers. If that's okay, the next concern is the increased width of 1 inch, which, due to a different offset, will mean:
              - the outside edge of the rims will move further out by 31.7mm.
              - the inside edge of the rims will move further away from the body by 6.3mm
              - the total offset change is 19mm per wheel; which is a total track width increase of 38mm.
              - steering characteristics will change due to the offset, so check for rubbing in the front at full lock.

                They told me that too, its rubbish.. alot of people on here including me running a wider offset than that. Im running king rims 16x8 -13 and my tyre is flush with the gaurds, so 0 offset would definatly sit in the gauds

                          A useful calculator for different wheels and tyres, including offset and track can be found here:

                          http://gti-vr6.net/library/engine/Sc...ldiameters.htm

                          Only problem is that you'll have to convert inches to mm by multiplying by 25.4

                          Edit: The track calculation here is incorrect. Track should only change when offset is changed.
