I wonder if these modern E rated tires have the same softness as the old D rated tires. I am assuming so because these should be designed for Broncos, Jeeps, and 4 Runners too not just trucks.

Well they are both E rated if ure looking for 37s, I have heard great things about Falken but D rated and they have a nice one in the 38x13.8r17 size that's D rated. Lookwise I love these RT Pros I just hope they are not too stiff in the size I want but I'm afraid they will be.

For an RT they look amazing, I wonder how they will be against the Falken RT01s. My only issue is that most sizes I want are E rated, as a matter of fact I don't even think they have a D rated tire. Hopefully the new E rated tires are the old D rated tires. I want the 37X13.50r17 size when they...

Too bad they don't make these for 37s and associated full suspension lift kit to come along with it.

Thanks for the tip.

Lol Chat gpt became self aware on July 17th 2025. It declared positive offset wheels as eternal enemy.

I hear you, and I don't trust it since the damn thing contradicts itself, but was just entertaining it. I listed all the things I am willing to do like crash bar removal, JKS kit, and rockslider trim and specified 37x13.50r17 and the fact that I am willing to go with the Hoss 3.0 steering rack...

When I asked why it kept saying assuming you want full articulation lock to lock without rubbing and if I will use the JKS kit and don't mind possibly trimming the rock sliders. When I suggested +6mm offset it said it may be too much and it can run the UCA and shocks in certain angles...

Well I asked it to give me the optimal wheel size and offset that is the most practical for properly clearing 37X13.50r17 tires in articulation and lock to lock in off camber off-road situations. No matter which tire I chose in 13.50 and if I assume JKS kit and all it always defaulted to -6mm...

Yeah, I'm sure those RT01s are solid tires can't go wrong with them. I was feeding some detailed info about upgrading the suspension lift to Chatgpt lol and no matter how I word it, the answer is the same, it is recommending -6mm offset wheels if running 37x13.50 tires for optimal off-road...

What size and manufacturer tires are you running?

Oh wow man that's crazy so a 37 should be no problem at +12mm offset 17x9 wheels. Which 38x13.50 are you running and which lift kit and shocks are you using? Did you have to use the JKS kit and did you have to trim anywhere else besides the rock rails?

Makes sense, so if you go with 13.50 width tires, what is the most positive offset you could go with safely (rough estimateof course). I'm thinking 0mm or +6mm maybe, assuming proper 3 inch lift kit.

That's why I am so confused because Icon recommends 0mm offset with their lift kit when using 37x12.50r17 tires and Readylift recommends +18mm on their site, and I'm here sitting wondering what the offset should be for 37x13.50r17s on 17x9 wheels. I am assuming on a 13.50 width, it should be...

Looks like they have updated the chart as the old chart made no logical sense. Looks like they updated this table as it didn't make sense. https://www.toyotires.com/product/open-country-rt-pro/

What do you think about the new Toyo RT Pros?

Oh wow so the Falken in 38 is true to 38, that's good to know. I like that one because it is a D load; however I am considering the new Toyo RT Pro as well. I still got some time before, I do this. Do you recommend steering rack upgrade for this either the new Ford one or the 74 weld, also do...

I appreciate your input, I also think 37x13.50r17 would work with the JKS kit, and taking off crash bars, and I hope I don't have to trim rock sliders. If people can fit the big Toyo 37 which is 560 revolutions at 14.6 inch width then a Toyota RT Pro at 565 revolutions and 13.6 inch width...

It's interesting you brought this up, I was on their page just now and they recommend +18mm offset wheels when using their kit, they also claim at the +18mm positive offset you can run 37x12.50 tires as well as 38x12.50 tires. Your picture illustrates the upper control arm rubbing on the spring...

Yeah, it doesn't seem too bad and looks great, price is pretty good too. The Falken shocks arent bad at all for that price.
