Yep its another one....really hope someone has an answer tho...we have a Prado with 6in rims and the very hard to find 215/80R16 attached to them....a friend can give us 4 hardly used 235/70R16 are these going to fit?...they will mess with the speedo only slightly I think....and the load rating is different....Any suggestions...we can also get hold of 265 75R16 but they will definitely need the 7 inch rims and even then doubt that they will sit within the guards....does anyone roughly know how much a set of rims would cost .... thought I would ask u guys these questions first...as Im sure someone has been down this track before...

Martin,
The 235/70R16 will fit on a 6 inch rim. But I expect it will not be legal because the load index is less that 107, which is what is written on your tyre placard.

Most common replacement size is 225/75R16. Can get a good range of LT tyres in this size.
If you want to increase diameter, then a few tyre companies such as Maxxis and Toyo make a 215/85R16. 235/85R16 will fit your rims, but will put your speedo out by about 7% and the taller gearing will suck the power from the petrol motors and to a lesser extent, the diesel.

If you go to 7" rims, you'll also have to factor in the cost of flares (starts at say $160 for the 35mm rubber flares).
Cheapest option at present is at your Toyota dealer. They are selling off the 16x7 Prado rims for about $120 each (half price), which is the same cost as the white spoke rims. And these rims are rare on the second hand market.

If you go to the 7" rims, consider fitting 245/75R16 tyres - good range of LT tyres in this size and it will only affect the gearing by 3%. Alternatively, a better range of 265.70R16 tyres are now available - strongest ones are the BFGATKO and Bridgestone D694LT in this size.

A lot of people also fit the 265/75R16 to these rims, on your RV, the gearing will change by 7% and you will need a mild suspension lift to prevent them hitting the front mudflaps.

Also consider, the wider and heavier the tyre, the more it will knock around your fuel consumption.

Hi Phil G

I am interested in your comment re the 16x7" steel prado rims being sold off.

I have a Hilux SR 2007 model. been phoning wreckers to get some pre-2003
16x7" steel Prado rims - they apparently have a 20p offset and fit the hilux perfectly. Also they are as rare as hen's teeth. are these the rims you are referring to?

Would that be all Toyota dealers in Adelaide.

If so thats great news to me as I was about to give up hope and go with some aftermarket white steelies - I prefer the Toyota rims - they are made of much thicker steel.

I too am looking at fitting either 245/75R16 or 265/70R16, but can't decide - the 265s probably will give slightly less fuel economy, and theres the risk they will rub. A problem if you find that out after fitting. Hence may stick with 245s. Probably wide enough for a Hilux anyway.

Cheers
Sobriquet.

Thank you Phil,
a few things to ponder from that...especially the fuel consumption with width & weight of tyre...we want to go on the gunbarrel in july & wanted wider tyres and want to give a little more clearance too....the load rating is important as we have a campertrailer in tow and kids in the back... (of the car not the trailer LOL) Thinking of doing the change over for a while but it wasnt till we had the offer of free good condition tyres that made us do more research....The fuel consumption is terrific in the parado too... dont want to change that really....

the 235/85R16 sound interesting "get outmore" that gives us the load rating +

Cheers
Martin & Tina

Sobriquet,
Yep, Toyota are selling those rims new for the same price as you'd get them second hand. They called it a "half price steel rim sale" and its been going for a few months. I bought one of the 16x7 rims from Cornes Toyota about 6 weeks ago for about $120 for a friend. Any Toyota dealer in Australia will sell them. They just have to order them up from Melbourne.
Heres an EBAY advert from Jarvis Toyota.

Thank you will check that out as that gives us a better load capacity

Gday getoutmore!! (I prefer calling you Davoe),
Hope all is well!

The two problems with Martin's RV Prado are gearing and clearance. Toyota fitted numerically higher ratio diffs to the RV Prados to allow for the fitting of smaller tyres. You are going from a standard 750mm diameter tyre to a much taller 810mm diameter tyre. I had a friend who fitted the Bridgestone 661 in the 235/85R16 to a RV6 and was pretty unhappy with the result - turned it into a slug and the tyres would hit the inside tyre wells when flexed up. Need a lift to get clearance at the front as well. The diesel models don't suffer as much as far as the gearing goes. Speedo will be about 5% out.

I'd fit them to a diesel but probably not to a petrol model.

mmm bit sad that you cant fit a 32" tyre without problems
a 235x85x16 would be a good fit for a 6 inch rim and are certainly bush freindly with availability and choice
