I'm looking at having some Toyo Celcius 225/75/R16C Tires installed on our 2007 E450 Class C and I'm looking for firsthand opinions on how well they have been for you. I'm open to suggestions of other brands of commercial 121 rated tires also.

I am very happy with the Toyo Celsius Cargo on my Sprinter. I have about 15,000 miles on them and no complaints.

My size is not 121 rated. Be sure the tire store know they are asymmetric and installs them with the proper side facing out.

On a 31' Class C, you are wise to go with the commercial 121s!

I'm not sure about your brand question.

General Question/Comment: How many miles do you expect to put on them in the next 6 years? If not more than 20k, then you don't need tires that have a 60,000 mile warranty.

Safe travels!

My choice is not based on a warranty, I based it on load carrying capacity. On occasion I'll be pulling a car hauler with a 2 seat roadster and a motorcycle and need the extra load capacity.

This link will take you to a copy of the "Tire Replacement Manual". This follows the DOT guidelines for tire capacities and load inflation tables.

Go to page B22 for the tire size LT225/75-16. Note the load ratings and inflation pressures for that size, and relationship to the letter load rating.
No here is the link for the Toyo Celsius tire.
https://www.toyotires.com/product/celsius-cargo/
Note that both the LT and "C" is listed in that size. They show the capacities as the C is higher but is it really? I am confused a bit. The tread is slightly less, and the weight is 2 pounds lighter for the "C" version. This could indicate that the higher load capacity is due to the lighter tire having less heat generation, not actually being a stronger or better built tire. Going back to the "Manual" that size tire, derated for a dual mounting @ 80 psi is 2,470 pounds per tire or 9,880 pounds per axle.

Any brand 225/75R16C C-Metric tire will have the 3195 lb load rating. They all conform to the Tire and Rim Association standards and its the T&R assn who develops the size/pressure/weight charts that all of the tire makers use.

Michelin Agilis Cross Climate, 225/75R16C 121/120R LRE MSPN 41578 is also made in the C-metric size. Note that these are NOT LT tires, and also note that the C on the end of the size is a designation of the C-metric category and NOT of the Load Range.

That C-metric size is also available from Goodyear as the Wrangler Workhorse HT C-type, the Firestone Transforce CV, Continental Van Contact, the Hercules Terra Trac CH4, the Nokian One HT, and the General Grabber HD to name a few.

You might find this document useful.

Note that the C-metric tire in the 225/75R16C is rated at 3195lbs single wheel and 3085lbs dual wheel.

The OP's choice of extra-capacity tire for his particular needs looks good to me.

The Toyo brand always had a good reputation. I never read anything bad about them and they have been around since at least the 70's.

I like CharlesinGA's reply.

I am partial to Michelin, but could easily be pursuaded to go with Toyo if there was a significant cost savings.

The oil companies at Prudhoe Bay at the end of the Dalton Highway in Alaska uses Toyo commercial grade tires and they are about the only tire that holds up on the sharp rocks on the road.
