P metric tires vs lt

[etoften]

Is anyone running p metric tires instead of c rated Lt? Lt tires seem to be overkill. My chevy colorado zr2 has a gvwr 600 pounds heavier than the jlu and has p metric as the factory recommended tire.

Limited to smaller tire sizes with P Metric

A lot of tire choice goes beyond load rating.

Some tires only come as LT variants. If you want brand A, model B, in size C, you get an LT tire whether you want that or not.

Then there's off road performance. You may want a stronger sidewall and better puncture resistance. That tends to push you into the LT class tire.

But for the most part, most people don't even think about P vs LT when picking out tires. They want a particular size and type of tire first. And many people stop considering other factors at that point.

There's no reason to not use a P rated tire over an LT if that's what you want to run and you can find a tire you like that fits the bill.

Share your thoughts exactly. But doesn't jeep list the lt as the recommended tire size? Seems odd.

There's a number of sizes that can come in either P or LT versions depending on the brand and model. So the specific size recommendation doesn't necessarily require an LT over P. Though it may be nigh on impossible to find a P rated tire in that specific size.

For the most part, the non-metric sizes (like 35x12.5/17) are all LT tires.

Some metric sizes are LT. They would be listed something like 285/75R17LT. The manufacturer will put it in the product literature.

As far as why Jeep would have a size where you can't find a P rated tire, it's likely that many other design considerations drove the choice.

Passenger tires (P-metric) are designed for lighter loads, smoother ride, and fuel efficiency.

Light Truck tires are built for heavier loads, towing, and off road durability.

So if you're airing down to do somewhat extreme trails then you're going to want LTs.
