Going larger on tires without negatively affecting performance?

I currently have 15,000 miles on the stock tires on my 2023 SR5 double cab with 6.5' bed, and TRD Off Road package. The information regarding tires makes my head spin. I am looking ahead on what to get when it comes time to replace my tires. I have no intention of lifting, or altering the truck in any way. I do tow a fair amount with this truck, but the reality is that in large part it is a grocery getter. I am retired and am on pace to put approximately 10,000 miles per year. I will be looking for a good quality tire, and am willing to pay for quality. I would like something that appears more " Truck Like".. While I am retired, and don't "Need" to travel in the snow, I do travel to Northern Maine with an enclosed snowmobile trailer with a gross weight of 7000 pounds. I also tow a small dump trailer, and a twenty foot 10,000 pound gross equipment trailer.
Should I limit myself to the stock size? Strictly for appearance, is it possible to go slightly larger without affecting anything? I have this truck warrantied for ten years/10,000 miles. I don't want to do anything that will affect the truck in a negative way. Are these ten speed ( I assume computer controlled) transmissions confused/affected by altering the tire size? Thanks very much. I appreciate the knowledge here.

 

You want quality go with Michelin. They are usually 80k tires. In your towing application, recommend LT tires. Standard tires are (P) for passenger and are light duty (cars come with (p). There is a thread on here regarding the question why our trucks are equipped like this and should come standard with LT tires (Light Truck-metric" size; it was designed for use on a vehicle that carries heavy cargo loads or tows a large trailer.)

 

You could go larger and it would be fine, these trucks make enough low end torque that it wont bother them.

I would stay away from BFG KO2's if snow is a concern. I found them to be very mediocre in snow. I have heard that the new KO3's are supposed to be better designed for snow.

 

define negative way? cause to some going from a "relatively small" P to a large E is pretty negative to both ride quality and MPG while offering arguably negligible towing improvement

 

I agree with the Michelins. You can’t go wrong. I have the stock ones on my 22 sr5 or and can’t complain. The ride is great, and mileage is strong. We have had them on our 2001 4Runner since new. We replace them every 75k.

I went with Vredestein 275/60/20 slightly oversized but not an LT tire. I ran LT load range E tires on my last Tundra and it was kind of like riding in an empty dump truck. I tow a 6500 lb travel trailer on occasion and don't see any limitations from the tires. I am well within the weight ratings of the tires with the trailer connected and gear in the bed. There is no discernible impact on fuel economy and they did fine in the snow we had this winter, which wasn't much. Out west Les Schwab stocks them so that's the route I took.

that michelin rubber is ridiculous durable, secret formula

 

Yes, I would definitely go LT. It will be a matter of figuring out what tire to buy, and if, and how much larger than stock.

 

Agreed on the Defenders recommendation.

The more tire weight and diameter you add to each corner, the more your truck will be in boost, and the worse your fuel economy will get.

Tall skinnies (285/75r18, basically a 35x11) work for me in my 5.7L truck. I definitely took a 1-2mpg hit, though.
