Hey everyone,

I'm just in the hunt to get a set of summer tires for my 2000 Dakota Club Cab 3.9L and was wondering what the minimum load rating required is.?? Looked on the door, and it simply states that the rim is 15x7 and the stock tires were 215/75R 15's..
So was curious if a 96H rating would be enough?

Thx



huh ?

We're used to seeing load rating in pounds, what do you mean ?

From the Tirerack website:

Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire's service description. A service description identifies the tire's load index and speed rating. Service Descriptions are required on all speed rated (except for Z-speed rated) tires manufactured since 1991.

The first two digits (87S) represent the tire's load index and are followed by a single letter (87S) identifying the tire's speed rating.

Load Index

P195/60R15 87S - The load index (87) is the tire size's assigned numerical value used to compare relative load carrying capabilities. In the case of our example the 87 identifies the tires ability to carry approximately 1,201 pounds.

The higher the tire's load index number, the greater its load carrying capacity.

89 = 1,279 pounds
88 = 1,235 pounds
87 = 1,201 pounds
86 = 1,168 pounds
85 = 1,135 pounds

A tire with a higher load index than that of the Original Equipment tire indicates an increase in load capacity. A tire with a load index equal to that of the Original Equipment tire indicates an equivalent load capacity. A tire with a lower load index than the Original Equipment tire indicates the tire does not equal the load capacity of the original.

Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 110.

Much easier without figuring in codes that include speed rating. Just figure the weight of your Dak, plus the most it can carry, then divide by four to get the minimum load rating for each tire. The speed rating has nothing to do with this and doesn't need to be considered for the poster's question.

Okay, let’s simplify this.

The 215/75-15 tire in general seems to have a code of 100 therefore a tire with a code of 96H (the H is the speed rating) would NOT be adequate for the Dak.

Sounds like tire you are looking at is smaller than stock. For your safety make sure you use at least the size that came on the truck. I would guess that you are looking at a 215/70 in place of a 215/75. That would not work well for various reasons too numerous to mention here. If you want a 70 series try a 235/70 that would have a rating of about 102 and the diameter change is small. Do a search here for a size converter program. There used to be one listed. I used to have it bookmarked but I lost it somehow.

BTW, a tire rated at 100 has a maximum load of 1764 lb as per the chart. A 96 has a maximum load of 1565 lb. that is a 99 lb difference per tire. I wouldn’t risk it.
