Have been running 205 R 16 HT on Ford Courier wanting to switch to AT's
Trying to decide whether to stick to 16's which cost more for rubber or switch to 15's which are cheaper...
How much would 15's affect fuel economy, especially as I will be towing a camper trailer...

I have a prado running 225/75/16 BFGs AT on 16 * 6 Rims. They have been a great set of tyres and I will buy them again in a couple of months. My current set have done 90000 klms but I now wouldnt attempt another trip anywhere before replacment. I too considered changing rim sizes but the brakes woulnt allow them to fit. I also dont know about the legal implications of changing rim sizes, try a search on this site as ive seen this Q a few times.

The load rating of the small 15 inch tyres are poor. Stick to 16's.
The 225/75r16 already mentioned would be a good replacement.

I had 225/75 16 BFG A/Ts on my Rodeo. Now I have 31x10.5x15 MT/Rs. My fuel usage has gone up a bit. However this is because the overall diameter increased not because I chamged to a 15in rim. If you go 15in and want to keep a similar overall diameter get some 30x9.5x15.

Although if you do buy 15s you will need 5 new rims and that will cost you about $260 for steel ones.

As said by the others, the 225/75 16 BFG A/Ts were a brilliant upgrade over the 205s. I replaced my 225s at 70k but they still have tread left so I can put them back on if the RTA wants me to :-)

Hi dan
I have a set in the garage, 235/75 bfg at's from my courier.
I now have 31's, they are about 10% bigger in diameter. You Hardly notice the power difference but fuel has gone up very slightly.

If you fit different tyres they must be at least the same load rating as the originals, or greater. You may find that this limits your choice. I think the originals are Light Truck with 108 load rating.
