0.25 ounces to 2.5 ounces
- Most passenger cars typically require between 0.25 ounces to 2.5 ounces per tire for a good balance. Here are some general guidelines based on the type of vehicle: Compact Cars: Usually need around 0.25 to 1 ounce. Midsize Cars: May require 1 to 1.5 ounces. SUVs and Trucks: Generally need 1.5 to 2.5 ounces. Remember, these are general numbers.

The engineers who designed your vehicle determined exactly how much weight your vehicle could safely support based on your tire size and tire pressure: the load index. A load index of 91, for example, translates to a safe carrying capacity of 1,356 pounds or 615 kilograms.

Load index is the load carrying capacity of your tire. Displayed in both pounds and kilograms, it denotes how much weight each tire can safely support. The tire’s load index is present on the sidewall, oftentimes directly to the right of the tire’s size (above, the “125” is the load index). While a tire’s load index isn’t referred to nearly as much...
In short, load range is an outdated way of listing a tire’s load carrying capacity. Listed on the sidewall as a letter (C through F are most common), it’s based on the tire’s ply rating. The higher the ply count the higher the manufacturer rates the tire’s load carrying capacity. However, with all the advancements in modern tire technology, fewer (...
It’s very important that you don’t mistake these two as being the same. While load index is an exact specification, load range can be a bit misleading. For example, one tire manufacturer’s E load range tire may have a load index that is the same or even lower than another brand’s D load range tire. We’ve seen E load range tires with a load index of...
So what happens when you overload a tire? If you’re lucky, all you notice is the visual sidewall sag present at the bottom of the tire. The tire will look similar to one that’s under-inflated. If you aren’t so lucky, or continue to drive the vehicle with overloaded tires, premature tread wear will inevitably occur. In a worst case scenario, you cou...
Another example that showcases why load range isn’t everything can be found by comparing Nitto’s LT295/65R20 Terra Grappler G2, which has an E load range, with the F load range LT305/55R20 version of the same tire. In this case, the LT305/55R20 (though being F-rated) has the lower load index of 125 vs. the 129 load index of the LT295/65R20 G2’s. In...
Keep in mind that a tire’s peak load carrying capacity can only be achieved at the manufacturer’s maximum inflation pressure. This too is printed on the tire’s sidewall. A few things to keep in mind when airing up to max inflation is to: 1. Air up when the tire is cold (for utmost accuracy and to avoid over-inflating) and 2. Though your load carryi...
If you’ve paid attention to today’s lesson so far you know that, on a single rear wheel truck with a 10,000-pound gross vehicle weight rating (GVWR), the tire information listed here in the size column means they possess a load index of 125. And because a load index of 125 means that each tire can carry 3,638 pounds apiece (14,552 pounds in total),...
When buying new tires always remember that it’s best to stick with tires that have the same load index (or a higher one) that came on the vehicle from the factory. This is especially important for vehicles that tow or haul at or near their maximum GCWR or GVWR capacity. You can go with a bigger tire, provided its approved rim width matches the whee...
Nov 25, 2022 · A tire with a load index of 95, for example, can sustain 690kg (1512 Ibs) of weight. When purchasing a new tire, you should consider load ratings and speed ratings simultaneously. Tire Load Index Chart. The majority of passenger-car tire load indices are in the 75-100 range, although some are higher.
