I'm getting new rubber for my Prado GXL. I've decided on BFG A/T's (based in part on feedback on other forum replies) but would be interested to hear from anyone running 275/70/16 or 265/75/16 on theirs being that the standard is 265/70/16, especially the effect of the 265/75- on speedo calibration and gearing.

Brookey,

I run 265/75's and it actually made my speedo read correct against my GPS. It does effect the gearing and I only notice it when going up long 7 degree incline for about 5Km's where I have dropped about 5 KPh according to the speedo of course. Obviously better mileage on the tyres should result because of the increased rolling diameter. Don't put a lot of faith in tyre brands mentioned on any forum after all who's going to admit they made an incorrect choice when they have just forked out $1000 bucks or so. Just be carefull as the same tyre brand/pattern can be made in different countrys and exhibit different wear characteristics than others.
I like to look at where I normally drive and get a tyre to suit. ie if I am doing a lot of outback work I will see what the local station owners, outback hotel owners drive on. We have so little time to enjoy our land

I have had BFG AT for the last 60K km (on thios car). Thers's still a reasonable bit of rubber left.

Have not been into stony country, but they do most other general usage i want.

Depending on the original tyre fitment there may be some speedo error. (7% on RV & 3% on GXL).

MTR might be the go if you are after a mud tyre (without mods of large lift)

I've been through this process

I would recomend joining the prado group at this address:
http://www.geocities.com/prado_95/90scool.html
Then find the article by Phill G :
Files / AAA Prado TechTip Files / Prado Tyres FAQ.DOC
You'll be hard pressed to get better advice than this article
I ended up getting the Cooper 10 ply 265/75/r16's
Speedo is out about 3% and I have'nt noticed any change in the gearing
A mate got the 275/70/16's and they rub at the front mudflaps

Cheers

Thanks for the feedback. I'm now leaning toward Cooper S/T' 265/75/16's in the light truck construction over the BFG's. Still got a couple of weeks before I head north so still a bit of time to decide.
