the bigger wheels the less power you get to wheels. so you making it worse with too big wheels. looks good maybe but not drive as it could.

True, but I think my biggest concern is the gear ratio as low range would go faster than normal which isn't nice.

90% of my driving is rural highway driving in 110km zones. Do you think the bigger wheels would increase or decrease fuel efficiency at cruising speeds like that?

To a certain degree it would help to move the tyre away from the slope of the spring perch; over in the USA many people fit wheel spacers which are illegal here.

If you fit 215/70/16 you don't need low offset wheels or wheel spacers, they clear the spring perch on factory rims. Even 225/70/16 just barely clears. 215/70/16 all terrains is by far the most popular size for lifted Foresters, literally 1000s of people are running them

225/70/16 ATs on Toyota 86 rims (+48, same offset as your Forester rims) with 2.5" lift:


215/70/16 BFG KO2s on factory SG XT rims with 2.5"/3" lift"


215/70/16 BFG KOs on factory SG XT rims with 2" lift & Pedders HD springs:

Bigger more aggressive tyres will affect fuel economy. If you want ATs maybe if you fitted something like Bridgestone AT D697s rather than, say, BFG ATs would have less impact on fuel usage.

Going from 60 to 65 series makes a bit difference in performance particularly if you are doing a lot of high country tracks. Going bigger I.e. 70 or 75 series you run the risk of getting stuck on a steep climb.
I changed my diff ratios and low range which has overcome this issue.

How did you change your low range ratio? I didn't know that was possible

Low range from the SF gear box, 4.44 diffs front rear and a .738 5th gear.
You cannot believe the difference in both hi and low range. Also the torque is in a more usable rev range.

I'll have to keep that in mind! And an eye out for an SF gearbox!
