Prado Rim Size & Offset Database

[mjrandom]

Steve generally fitting 120 series GXL rims is illegal because the track is narrower. I haven't done the calcs on a GX and the different tyre width. You would be better to get 150 GXL wheels or a legal aftermarket alternative which will br +25 or less. Typically you can increase track by up to +25mm but cannot reduce track at all. This usually refers to the widest track that the manufacturer lists for that vehicle.

Hi, I'm new to this forum and was wondering if I could ask some questions.
I have a 150 GX with the standard 17/6.5 wheels. I'm getting a camper trailer built to my specs and have an opportunity here to match wheels on the camper to my prado.
We are setting up for the big lap.
The tyres I'm currently running are 245/70/R17 and about ready to be replaced. (I was thinking of Cooper AT3's).

I have been told the above tyre size might be difficult to source in the outback if I should need to replace one. i.e I'd be more likely to source a 265/65/R17 tyre.
I have an opportunity to purchase some second hand Prado 120 17/7.5 rims which will accomodate the 265/65/R17 tyre.
Is this a good idea to replace my rims?
I believe the offset from a 120GXL is more positive (+30) than the 150GXL (+25) according to the first post in this thread as follows. Is 5mm something to be concerned about?

Any thoughts on this welcome.

If the sizes on the sidewall are the same, they will fit.

Hi Andrew , we have a 120 prado GXL with 265 65 r17 grand treks. I have bought some bridgestone 265 65 r17 desert dueler tyres. They are a different width. I want to know if they will fit the rims. Cheers stotty

Derek, is there any additional modification required (i.e. to mudflaps, guards, guard liner, etc) to fit without ANY rubbing?

There is slight rubbing at full lock on the mudflap, an easy fix, and the UCA need to be replaced.

Cheers Derek

i can confirm 8.5" x 17" rims in +14 offset fit perfectly on my GXL 150 with 285/70/17 tyres.

Nice! No rubbing at full articulation with LR UCAs? The 150 series owners will be pleased!

Thanks mjrandom. Just trying to decide if I change my rims on my camper. The camper came with 120 prado alloy rims and I was interested that if I really needed to use them in a sticky situation I could as interchangable as spares. Looks like I might need to sell the 3 rims and tyres and get some newbies.

If you are just looking to have an emergency wheel then I wouldn't worry. Fit them up and check they are ok. For the record now that I am getting a 150 I wont be changing the 17x7.5 GX steelies on my trailer assuming that they fit the 150. Again as an emergency measure only. And that does happen. Years ago I was sand driving North of Yeppoon (let's just say I didn't see a particular sign and leave it at that) and staked two tyres. I was pulling my trailer (same as I have now) with a tinnie on it. As the wheels were the same offset I simply jack knifed the trailer in the bush and grabbed both wheels off the trailer. Swapped the tyres and headed back into Yeppoon for repairs. Resumed the journey several hours later.

Yes it wont be legal but for the sake of getting out of somewhere to get repairs I don't believe it will be an issue.

It's interesting that the offset for the 90 series goes the wrong way

90 Series

• Alloy/Steel 16x7" ET15
• Steel 16x6" ET30

Usually, the narrower tyre will have less offset i.e. 16x6" ET15. What does your tyre placard say?

Based on Andrew's data the 120 wheels wont be legal on a 90 even if that fit. The offset on the 16x7 wheels is +15 while the offset on the 17x7.5 wheels is +30. That would reduce your track by 17.5mm. Cannot reduce track at all.

I have a simple question. Will the following fit my 120 2009 Grande:

Dick Cepek Torques
Dick Cepek Gun Metal 7
(I already know Dick Cepek DC-2's wont... very annoyed.)

Or what other rims will. Every time I find a decent wheel/rim, I find out they don't make it to fit.
The table needs to be adjusted to say what sizes (for a 120) will fit ie 7.5 to 8, -x offset to
-/ +ve offset etc. Kind of like a Wheel chart for dummies, except real simple as I have trouble reading the "for dummies" books.

mlc, confused, alone and in the foetal position trying to come to grips with wheel cjhoices.....

Just fitted Gun Metal 7s to a 120 GXL with MT ATZ 4 rib, standard suspension, no problems at all.

This is probably a silly question but I don't really understand all these offset calculations. Will a set of 120 standard toyota alloy rims fit on my 90 series.

I found a fitment guide listing many rim sizes and offsets here:
