I received the email below asking for input, and with the reader’s permission, decided it would be nice to respond to his question on the blog and share with everyone.
Do you have a question for RoadTraveler.net? When you do, send an email, maybe RoadTraveler can help.
I was wondering if I could pick your brain for a minute. I just bought another F350 CC today. 97 Powerstroke with built E4OD. It is going to need rubber soonish, and I have also recently bought a 2700 lb slide in camper. I am looking for a load range E 315-75 R16. All i have found so far is the Toyo MT. I am fine with those, aside from cost vs wear ratio. Any other hats you could throw in the ring?
Much appreciated, Red Thies
I love the old, first generation 7.3L Power Strokes, sounds like you found a good one. As you know, you have a substantial load with that slide-in camper. I assume you desire a load-range E 315/75R16 because you want the added capacity of over the typical load-range D, and possibly the added stiffness to reduce sidewall flex and heat.
Does the camper weigh 2,700 pounds dry or is that the gross-vehicle-weight-rating (GVWR)? My guess is that with the weight of that camper you will be very close to the maximum capacity of two typical 315/75R16Ds, which is 3,195 pounds each at 50-PSI. Depending on how you set-up the F350, you might have close of 3,000-pounds riding on the rear axle (I do) when you are wet & empty before you install the camper. Using these estimates, you would have about 690-pounds of total rear axle tire payload remaining.
I’m generally a fan of the Toyo M/T because it’s a high-quality, rugged tire that balances well and rolls nicely down the road. However, you raise a very valid point; value. The Toyo M/T is generally pretty expensive, and depending on the application, wear is not always fantastic. I also know a few people who didn’t get great mileage out of their Toyo A/Ts either. As the saying goes, your-mileage-may-vary, there are always others who can share they get great wear out of Toyos. Depends. Do you want a mud-terrain tire? Diesels can be hard on tires, and so can maximum loads, therefore starting with a tire that has a spotty reputation for wear is a big gamble.
The GoodYear DuraTrac LT315/75R16 is a load-range E tire, rated for 3,860-pounds each at 65 psi, a very healthy increase in capacity. But like the Toyo M/T, some seem to get great wear out of the DuraTrac while others receive a very short life. I like the appearance of the tread, but it hasn’t been able to lure me away from the Dick Cepek F-C II.
The Firestone Destination M/T is a load-range E in 315/75, and comes with a whopping 20/32″ of tread. The Firestone Destination A/T is also a load-range E, but is a very conservative 5-rib all-terrain tread design.
What say you?
