I am after some advice from the brain trust regarding tyre sizes. I am after either MTs or Aggressive ATs. Stock Size is 265 70 R16, roughly converts to 30.6" in old speak. Next size up is 265 75 R16, Converts to 31.6". Speedo error on my car is 4%. With the bigger tyres Speedo error will be 0.
For the guys running bigger tyres with auto transmission how much difference in fuel usage and drivability have you noticed. Most of my driving is in the city with 1-2 day trip out in the bush per month, one 4 day camping trip every 3 months and one big trip (1-3 weeks) every year. On the big trips I will be towing a 1 Tonne trailer.
I was doing this with a Petrol 3.8 Auto Wrangler running 33" tyres and the fuel usage went up approx 15% with bigger tyres but I didnt feel much change in drivability.
Cheers

That's about 50% highway and 50% urban/school runs/shops etc. But as a direct comparison, used to get sub 10's on a nice highway run to work (40km), now struggle to get low 11's. Auto behaviour hasn't changed much, a little longer before lockup in 5th in drive (more like 80km/hr) but no heat issues with box, still runs around 70-80deg c most of the time.

I am running Maxxis Bighorns in your suggested new size. With them, the lift, all the weight I carry, the roof rack and auto I pretty much get mid to high 13LPH around town which moves to high 12 to low 13 LPH on the hwy. I am not gentle on it though and do the speed limit.
When my wife drives around town she gets mid 11LPH so if you are sensible that should be acheivable.
One big thing I noticed is that under brisk acceleration from standstill the larger tyres have created a big gap between 1st and 2nd gear. This means it does drop off boost whilst the auto swaps cogs.
EDIT - Sorry, just noticed we are runing diferent tyres. Mine ar 265/70/17. I think the ones you mentioned wre 265/75R16 and I think they are overall about the same size.
Also I think that the bighorns I have are pretty heavy compared to other tyres so that is most likely contributing to my poor fuel consumption.
