First time owner questions

Hello everyone

Finally pulled the trigger and purchased a brand used 2021 SR5.

I know there are probably a lot of threads about what I’m going to ask but I’m new here and hopefully can get pointed in the right direction with wheels/tires suggestions.

I’ve been looked at a set of Lock Off-Road 17x9 with a 0 offset, or there is a choice of -12 offset, wrapped in 275/70s. I know the stock setup is a 17x7 with a +15 offset wrapped in 265s.

I run 285s on my truck but it’s also a Ford and irrelevant to the 4Runner setup.

My questions is .. Is this wheel spec going to be too wide overall? Is an 8” wheel more ideal for a daily on this setup? I don’t mind some fender wall adjustments but I’m not really looking to viper cut at the moment. I’ve been told by 2 different shops that it would work, and was told by another that it wouldn’t, that I would need to level or lift with something like a Bilstein 5100. I have talked to someone about a 1.5” front and .5” rear to level.

I guess my overall question is.. Before I go doing too many modifications right now, (will be doing a lot next spring) what is my best option for wheel/tire choices? I want more mean look but I also hate the stock look and how far the wheels are tucked in. TIA for any replies!

Welcome to the forum. I don’t know how long you’ve had your 4Runner but my advice is to live with it for a while before you make any changes. Take a few months and read through the bazillion wheel and tire threads which have answered your questions many times. Plus you will find lots of other useful info.

That said, 9 inches is pretty wide. I think Goodrich recommends that KO2’s in 275 be mounted on rims no wider that 8.5” You’d have to go to 285’s if you want to use an 9 inch wheel. You might find another tire that is okay with a 9 inch wheel but …

 

I’ve studied them fairly extensively, that’s why I was iffy on the 9 wide wheel without a lift to begin with because I knew it’d most likely demand 285s plus I didn’t want to make it a modded nightmare. I know how much room I’ve got to work with regarding the offsets buts I know each truck can be different. The 8.5” is was the original plan and I was being a little overzealous if I must say about a 9” wide wheel.

 

There are some 275/70s that will fit a 9 inch rim (Toyo for one) but it is a limiting factor.

 

I found and twice watched an interesting, well executed, tire footprint experiment on-line. He measured tire deformation & footprint at various pressures and a tire's ability to mould/roll over logs & rocks.
The results run against the common tire size narrative.
I, too, suggest driving on your stock tires and do your research. I used my stock Duellers until a dealership alignment scuffed off lots of rubber. Then I used AT20 takeoffs ( $200 for 4). They still had lots of life in them when I installed Pirelli Scorpion AT+. I also picked up a set of 4 stock wheel takeoffs for $100. That I am keeping for spares. Next year my spare tire will need replacement due to age and its getting an aluminum stock wheel.
