Researched bigger tires+lift, but now maybe just stock size upgrade?

Exactly those! I chose 265/70-17R in p-series load range

 

I live on the west coast as well. We deal with a lot of rain all at once and roads can get flooded quickly with lots of standing water.

My experience (yes, anecdotal) with KO2's is that they aren't as good as other tires in rain. The reason behind this is the random tread pattern doesn't funnel water out of the way as fast as tires with rain grooves......so to me it felt like the KO2s would hydroplane at lower speeds. Every tire that I've had with rain grooves have performed better in wet conditions.

That being said, I still think the KO2's area a great all around tire. They are pretty dang good in a wide variety of conditions.

 

On my F150 I ran 2 sets of KO2s. All are great performer's summertime. When roads get wet and cold, they are awful. I don't need science to prove it. Thought they were bad, and bought another set. Same thing, cold/ wet rear end would break loose often.
Switched to Michelin defenders and same wet cold conditions, same driver (me) and same road to and from work, the defenders gripped like glue. The compound in the KO2 reacts to the cold in bad way. Maybe it's because pickup trucks have little to no weight in the back? On the ford 150 forum many shared this info on cold and wet the KO2s are not that good.

 

My son in law runs K02s on his Tacoma with no issues on Vancouver Island. He also off roads it during the off seasons on the logging roads all around the community where he lives, way up in the mountains.

 

Not a lot of freeway driving at 65mph on Vancouver island though.

That's the big difference. Road handling at high speeds when it's wet.

Vancouver Island is beautiful though. Where does he live? I want to go back. Really enjoyed my stay in Tofino.

 

I am also running the stock size, P-rated Toyo AT 3, and they are perfect for my application. Maybe someday Ill do a lift, but only for ride quality and more clearance. For now the stock suspension is just fine. I think I'll go with the RCI full underbody skid first.

 

These seem very similar. The Toyo AT3 weighs 6 lbs. less, but has 13/32 tread depth vs. 14/32 on the Falken. Pretty much a wash:

 

So I have a 2020 venture and I wanna put some General Grabbers on it, buuuut there’s so much information in this thread that I don’t know what size to buy. I feel like the 275/70R/17 will work wothout rubbing or if it did would be easy to fix.

 

Yeah he drives the Inland Island every day in all kinds of heavy rain. It’s a divided high speed road the same as you guys have in the US, lol.

 

I really like the tread pattern on the Toyo, but wow they really dropped the ball on the sidewall. The Falken has a much beefier sidewall design that looks like it would be functional in protected the sidewall and adding some grip when aired down. The Toyo is more of just a design, like a hint of what the sidewall COULD look like if that had added it.

Even still, for mine I'm considering them in 255/80/17 for mine (stock suspension). At 50lbs, they're the lightest available in that size.

Though, I may just stick with something in the stock size or 255/75/17 that's lighter and cheaper than the Toyos.

Decisions, decisions.
