It’s a combination of things that throw off everything

Larger diameter tire, more rotating weight, etc...

No all terrain tire is ever gonna ride as good as all season car tire

From what i have read the OE Yokohama tire was designed for this car with subaru

We are in the market for the 2020 XT Limited ourselves and I’m looking at aftermarket wheels to put on it. Do you think even if I stick with the OEM tires on the new wheels, it would still cause all these issues? I’m not familiar how different wheels affect vehicles as I’ve always done stock.

If the aftermarket wheels are lighter than stock, they will improve acceleration, mpg, ride, and handling, and if they are heavier, they will make all of those worse. The problem is that it's difficult to make light STRONG wheels, the lightest strongest wheels are forged and expensive. You end up trying to balance weight, strength, and price.

Combined with the tire - if you get a heavier wheel and a heavier tire (wider tires are heavier) then it compounds the problem. I've experienced it myself where even on stock wheels, going +1 in tire size turned a car that was agile into one that felt dead and sluggish compared to stock because of the heavier tires. I've also experienced the other side - getting lighter wheels and using the stock tire size gave me better performance.

If you want to google the topic, key phrases like "unsprung weight" and "rotational mass" are most relevant.

Thank you very much for the information. Looks like I’ll be doing quite a bit of research on this topic then. I plan on staying with OEM tires therefore, would you have any recommendations as to specific brand wheels to look at? I’ve looked at Sparco, Enkei, and BBS.

In the next couple months I will be installing a 2 in lift by LP Adventure.I have an Onyx XT and plan on keeping the stock 18 in black rims but replacing the tires with All Terrains. Anyonve have a setup like this? I’m wanting to know how big I can go on that rim. Think I could go any bigger than 255/55/18? Would adding the Primitive wheel spacers allow me to go any bigger. Any help It is much appreciated!!

Here's a question. TPMS warning. I'm coming from a 2014 where I had spare rims that I used to run winters. The extra set of rims had it's own set of TPMS sensors, but no tire shop could re-learn the car, it was dealer only. They charged a fee, plus the hassle. I found the TPMS warning light to be pretty ignorable, a square of electrical tape did the trick! So, I just didn't both re-learning the computer twice a year and lived with the light. So in the end, I wasted some money by buying a set of sensors in the winter wheels that I never used.

I ordered a 2020 Onyx and am working this all out. Anyone have any insight to the warning? Is it just an idiot light like my 2014? Or is it flashy lights and chimes? i.e. how "ignorable" is it? And surely I hope it doesn't shut down any AWD/traction control type functionality?

I don't know the answers to your questions but this thread might help:

This post is a collaboration with taconugget. When we noticed how similar our Outbacks were, we figured it might be helpful to post photos side by side- that way members trying to choose between the popular Wildpeak A/T Trail sizes 225/65-17 vs 235 could see how they actually look. As a bonus, taco has some really cool photos of his new roof rack! As you know, I chose 225; taco has the 235s. Both fit without issues and perform brilliantly. Here we go:

Love the looks of the 501s and the 235/65 17 Wildpeak Trails. If I had to do it all over again I might go with 225s. I drive 100 miles a day and gas millage is a big deal. Currently with the 235s I get 26mpg in my 2.5L 4 cylinder on the highway. I get 19 to 20mpg city. The 501s and tires are putting me about 9 pounds heavier per corner which reduces overall torque and hurts the mpg. Had I gone 225s I would be saving about 5 pounds per corner almost 20 pounds total. I’m sure the MPG and torque would still be effected but not as much. With all that said I really love the tires. They handle off-road great they look amazing. They are quite and I still get pretty good MPG. Just to compare I was getting .5 more mpg on my daily drive with the all seasons, but 3-5 more mpg on city only driving with the stock all season. Also know the 235 are XL rated and have 2 extra layers or rubber. Adds to the weight but hopefully will hold up better offroad. I blew out the sidewall of the stock tires on my first trek offroad. Feel free to hit me up with any other questions. I will say I’ve gotten stopped more by people on the streets with this vehicle then any other i have owned.

Here are a couple more pics!

Here's my take on your important question. My 2019 3.6 came with 225/60-18 Bridgestone HP Sport AS tires, which are 28.6 diameter per Discount Tire. The Falken Wildpeak A/T Trail is reported to be 28.6 for 225/65-17, 28.7 for 225/60-18 which would be the size for the stock wheels. 235/65-17 is 29.2; 235/60-18 29.3 . Assuming those numbers are all legit, my 225/65-17 MR501s should be OK with the stock spare. That being said, if I get into some serious back country stuff I'll invest in another Falken/501 combo on an outside mount like the one mattytreks got- just for peace of mind.

Can you use your stock spare when you change out wheels on the Outback?
From what I've read you should be able to. That's what I might do if I can find others who would want my other three stock wheels and tires.

Running the Method 502 17x8 with Falken Wildpeak AT3W 245/65r17.

I don't have a side profile picture but I'll grab one soon. With the Readylift 2" lift, I get a very minor amount of rub when the wheel is cranked and I'm in reverse. A Little rubbing in this is nothing compared to when I had lowered GTIs 😂

Thought I would resurrect this thread with a contribution of my own... I have KMC 708 Bully's in 17x8 with Toyo Open Country ATII's in the stock size of 225/65/R17. I chose the Toyo's over the Falken's because I got a great deal on them at $102 a tire, and I like them so far.

Looks great! Is that an Onyx with a different grille, or a limited with the Onyx headlights (black sides) and lower grille trim removed?
