Why should you run Load Range F Tires? Falken Tires explains the need for Load Range F.

Bakari Howard and Drew Howlett discuss the trend of running larger tires on today's HD 3/4 and 1-Ton pickups, and why Load Range F tires are now becoming an important part of Falken's Light Truck tire lineup. There are two basic overlying trends that have posed the need for Load Range F in today's market. You can see the first trend if you look back at ¾ ton and one ton pickups over the past 20 years. These vehicles have gotten significantly heavier over the years, plus more power, bigger diesel engines, more carrying capacity, and more towing capacity. With a simple leveling kit, a lot of these modern trucks can fit a 35x12.50x20 tire. This created a need to make sure these larger aftermarket tire sizes have the proper load index to meet or exceed the original equipment tire’s load index.

Do the A/T4W tires come in different ply ratings? And what about the Open Range AT Plus? I understand they're made by Falkens sister company, and was hoping you can give an assessment. Thanks!

Can I run 35x12.50 20 125R load range F on my 2021 Jeep wrangler unlimited high altitude?
My stock rim is 20”

[@falkentire]

You could. Though a Load Range F might be a little stiff riding for a JLU. You could run into some clearance issues when turning. A lot of stock wheels lack the proper offset to clear a wide tire when turning lock to lock. You might also run into an issue with wheel width on the stock wheels. Those appear to be a 20x8, and the 35x12.5R20 is approved for 8.5-11.0" wide wheels. Another option to get the height of a 35" tire without the width is a LT285/65R20 which measures 34.8"x11.5". The LT285/65R20 is approved for an 8" to 10" wide wheel.

Can I run a lower pressure than oem if tire has a higher load rating than oem?I’m running 325/45R24. Oem tire size is 235/80R17. Oem tire pressure shows 55PSI.

Hello Raul. That's a question better directed to our tech team. Please email them at [e-mail], or call them Mon-Fri 8am-5pm PST800-723-2553 ext. 2. Thank you!

It’s actually the opposite

[@tself77]

@@falkentireThat really should of been addressed in the video as that's by far the most common scenario.

[@falkentire]

@@tself77 & @erice4611, using this online tool ( tiresize.com/pressure-calculator/ ), and based on Raul's question, assuming his new tires are a Load Range F and both sizes are an LT tire, then the calculator indicates he could run a lower pressure to support the same load. But there are several assumptions being made. That's why a referral to contact our tech department is a safer bet.

I do not under inflate her tires like others do
The max is 80psi. I run 60 psi
You really don't need the additional rolling resistance on the road,they will cup driving them at 30 psi.
they are 12.50 33 and look like they barely fit Rim anyway.
All you need is a grossly under inflated tire flexing and rolling off a rim

I think it's dumb they're getting rid of the wild Peak 3w

[@falkentire]

Hello. We appreciate your devotion to the A/T3W. However, it's being replaced by an improved product. The A/T4W. We think consumers will be just as happy, if not more so, with the new tire.

[@jamieeisenhower1560]

@falkentire but not a lot of people want to have all kinds of extra side walls to make the tire thick and being driving on the highway and having vibration problems Or have tires that ride like a rock my Jeep actually rides way better than your everyday SUVs

[@1234tellmewhatyourlookingfor]

You can send me 4 prototypes and I will test them for you.

[@frankleblanc6490]

I'm currently lifting my truck and researching tires. I'm leaning towards the Falken A/T4W, and was wondering if they come in different plies (4, 8, 10 etc). Is there any advantage to a higher ply? Thanks!

[@1234tellmewhatyourlookingfor]

F equates to floatation on mud tires.

[@1234tellmewhatyourlookingfor]

Before you laugh
Every tire has load ratings marked on its sidewall. This also applies to standard sizing and flotation sizing, commonly found on mud-terrain tires. To learn more about how to read a sidewall.

[@1234tellmewhatyourlookingfor]

Yeh I didn't buy tires on wife's truck they were a gift from her son.
They have E load capacity but a F rating
So I looked it up.
I'm not driving her truck down a creek, so floation doesn't mean that much to me.
