Tire Profile

[SRP09]

I've read many of the tire posts on here but haven't seen one that pertains to my question. Forgive me if I've missed it.

My 2009 Tundra came with 275 55 20 tires. I don't like the look of a "skinny", low profile tire on a truck and wanted a little more meat on the sidewalls. I was able to bump up one profile size to 60 without any rubbing. My last few sets of tires have been 275 60 20.

Buying another camper wasn't on my radar last year when I got the latest set of tires. They are P rated and will wear quicker with towing. I will switch to a LT rated tire with my next set. My question is- will I have better towing performance, less "squirm", with the original size, lower profile tires? In my mind, lower profile = less sidewall available to flex. But maybe I'm thinking about it wrong and someone here has some knowledge or experience that states otherwise. I'm willing to sacrifice looks for towing performance. Thanks in advance for any info that's thrown my way.

I think I would look at load rating as my deciding factor. Not sure if the low pro is rated as high as the "regular" tires.

That is true. I will be sure to check the load rating of both options.

"P" rated tires do not have the sidewall stiffness for towing a trailer. The "P" rated tires are for passenger cars/SUV's, that will give you a softer ride in the vehicle. "LT" tires are a light truck tire. The tire will have stiffer sidewalls for heavier loads and towing. The ride will suffer somewhat due to the stiffer sidewall (less flex) but the towing and hauling experience will be greatly improved.

My personal opinion is I would never tow with any vehicle that is equipped with "P" rated tires on the vehicle. I would change them out to a "LT" tire. You may need new wheels also that will fit the "LT" tire if the tire profile is changed.
