285/70 R17 on 120 Prado GXL

Hi Marc,

I don't reckon you'll like them for 80% bitumen 20% off road.

It's too aggressive for that usage.

Haven't heard of anyone going that big on a 120 Prado. Common upsize is to 265/70R17.

STT's are pretty good on the bitumen I reckon you'll be fine with the tread pattern if they'll fit under the guards,maybe you'll need a little 2" lift too for chrissy

overall diameter is 32.7" vs. 30.56" for the standard 265/65R17s

I'd be very surprised if they didn't fit. You'd have a 6-7% under-stated speedo (it says 100, you're doing 106.5), and a little less power ... from the different gearing)

As for the STTs, they suit me fine - I have 285/75R16s on my 100 Series which is almost the same change in diameter from the stock 275/70R16 and almost the same as the difference between that and the 265/65R17s they put on the higher end models today.

I don't mind the noise which is not that bad compared to the word ATs I had prior.

That said, mine get a reasonable workout off-road.

I don't think so. Go ask a Cooper dealer.

I have 265/70R17 Goodyear MTRs on my 120 prado with stock suspension and they rub slightly on the plastic guard liners at the front behind the bullbar. It also has to do with the way the liners were refitted after the bullbar installation but that is another story! The MTRs are almost identical in pattern to the Cooper STT if they are the new pattern.

On full lock there is only a finger width gap between the rear of the tyre and the front mudflap.

You may also foul the suspension component that sits just behind the top of the tyre. Run you hand around the top inside edge of the tyre and you will see the issue that makes it difficult to fit snow chains on the front of a 120 Prado. I suspect this might be an issue for your wider tyres.

Think you may be pushing the bounds with that one!

Can be done....

Need 2" lift (NOT ARB one), ARB Bulllbar and a bit of mudflups mods....
