Falken Wildpeak AT3W 6ply or 10ply?

This is a good question. I have had E rated before in a Michelin Defender and hated the way they rode....for like ten years, because they wore like iron.
I'm going with the Falkens next and really want the 235/85-16, but those are an E rated tire in that size. I'll likely go with the 6 ply in a 245/75.
My vote is for the 6 ply.

 

The "C" rated tires are rated to carry LESS weight than a "P" rated tire of the same size. You would gain nothing going to a "C" rated tire over the "P" rated tires that came on your truck. Those tires are designed for lightweight SUV's like Jeep Wranglers that don't tow or haul loads like a truck.

If you get the air pressure adjusted properly an "E" rated tire doesn't ride much different than "P" rated tires. When I was running "P"'s I kept the air up close to 40 PSI in order to be able to haul weight in my truck. The door sticker says around 30 PSI, the tires say 44 PSI for carrying loads. I split the difference.

"E" rated tires don't need as much air in them to haul the same weight. They are normally used on heavy duty trucks with 7000+ lb curb weights and 10,000+ lb GVWR.. On those trucks 55-60 PSI is normal unloaded, and 80 PSI loaded. On a 4000 lb Tacoma with a 5200 lb GVWR you don't need that much air. I run mine at 30 PSI and they will haul more weight at that PSI than the "P" rated tires at 44 PSI. The ride is virtually the same as my old "P" rated tires.

My "E" rated tires are 15 lbs each heavier than the factory tires. My fuel mileage is exactly the same as before. It isn't the weight that kills fuel mileage. Wider, taller tires with aggressive mud tread kills fuel mileage. Stay with something in a 265mm or smaller tire width, don't go more than about 1" taller than stock and avoid mud tires and your fuel mileage won't suffer noticeably.

 

Just do it ok? E

 

I have a mileage sheet for every month because I am reimbursed for my mileage at work. You are really worked up about this, do you want to talk about it over dinner and drinks?
