I want to put new wheels and tires on my 2015 Outback. The OEM tires are 225/65-17 and weigh 26#. I don't know the weight of the stock wheels but being 17x7 I think they are probaly 20-25#.
The wheels I want are Sparco Terra's that weigh 21# in 17/7.5. The two tires I am considering are: BFG All-Terrain T/A KO2's that weigh 39# and Yokohama Geolander A/T G015's that weigh 30#. The Yokohama's are a newer "improved" version of the Geolander A/T-S. Both tires are the stock 225/65-17 size.
The Sparco/Yokohama combination will be (depending on stock wheel weight) 3-4 pounds heavier than stock while the Sparco/BFG combination could end up being 10 pounds heavier.
My concern is with what effect a possibly 10 pound heavier wheel/tire will have on handling and wear/tear on the suspension.

I think it's going to have more effect on ride quality and acceleration than on handling or suspension durability.
I'm with Vigo on this. The heavier tires will make it ride rougher, it'll feel slower and the brakes will feel weaker.
Bet you won't notice the difference

Ride quality probably won't bother me. The Outback rides so much better than anything I have had recently I probably won't notice. Braking is something I am getting used to. The difference is noticeable between this and the Focus with 1" larger discs all around and 1K pounds lighter.
Weigh your OEM wheels/tires and use that as your baseline. OEM stuff is usually VERY heavy due to needing to never ever ever fail. But even if the new setup is heavier I suspect any ride difference will be in the knobby tread and stiffer/thicker sidewall and not the weight.
Besides, it's not like an Outback can get any slower.
