LT Tires vs. Passenger Tires

Monday, June 7, 2010 by Colin .
I have taken calls from people that want to use a standard load tire on their truck or sport utility when a higher load range is required. Based on the specs they read, they assumed they would carry the load. That was not the case.   

LT (light truck) tires are designed around the same basic rules as commercial tires. They have sufficient reserve capacity factored into the formulas used to designate their max load capacity.

P-metric and Euro metric tires, however, are not designed using the same set of rules. Their sizing system is designed for use on personal use vehicles which are normally less likely to be overloaded compared to a truck or commercial vehicle.

When looking at the max load of P-metric or Euro metric tires being used on light truck type applications (full size van, SUV, pickup truck, minivan, etc) the tire's max load must be reduced by 9%. 

It is always best to stay with the vehicle manufacturer's recommended load range even if you don't plan to carry a lot of weight. Our website will filter out the incorrect load range options when you enter your vehicle prior to searching.

I have the same question, I own a Diesel Jeep Grand Cherokee and I damaged a rear tire (Goodyear Fortera HL) while towing a Uhaul auto transport with a VW Jetta on it.
I dont think a LT would be overkill on my truck but I can't find any info about it.

Hello,

You can use LT rated tires on your vehicle. They will offer more stability when towing but your ride quality will decrease due to the reinforced design of the tires. They are also heavier. Depending on your size there may not be LT (C, D or E) load range tires available.

I have a 2010 Chevy Silverado 1500 crew cab, should I get LT or P rated tires for my truck?

Hello

You don't need to use an LT tire. A LT tire won't offer as comfortable ride quality but it will have better durability against damage and stability for towing.

i currently have tires that have are "P235/75R15 108S" and i am looking to buy tires that are "33x12.50R15LT".

will the tires i am looking to buy fit on my stock rims? since they are both 15". i have a 98 4wd dodge dakota

Josh, while both of these tires share a needed wheel diameter of 15", a 33x12x15 will require a wider wheel than what came factory on the 1998 Dodge Dakota. Also, the additional height and width of the 33x12x15 will likely require a lift kit for proper clearance. With aftermarket wheels that have additional width, it is possible to run a 31x10.50x15 without any rubbing issues.

Hi, I have an 09 Sierra 1500 SL. Stock tires on it now are p265/70/17. I do light off roading and would like some beefier tires, should I go with LT or stick to P. I don't tow or put it under excessive load.

LT tires are thicker and are commonly used for off-road use because they are more durable. The down side to running an LT tire is cost and sacrifice to ride comfort due to the heavier constructed sidewall. -- marshall@tirerack.com

Im going to order winter tires for my Toyota Tacoma Access Cab 4x4. I will be hauling a snowmobile with single sled deck on the back of the truck. (about 600 lbs. Can I use passenger tires or do I need LT tires? THanks

I have a fj cruiser 4wd base. Im looking for a c-load rated tire. Is this acceptable? I'd like to have the mountain snowflake symbol.
Wednesday, October 29, 2014 by Tire Rack Team:
Ian, standard P-Metric tires should be able to support this vehicle and payload without any load carrying issue. While LT tires can be used, they may be a bit overkill for the application and typically ride stiffer due to the thicker sidewall. -- marshall@tirerack.com
Wednesday, October 29, 2014 by Tire Rack Team:
John, P-Metric or C-Load Range LT tires are sufficient for this model. It does not have a gross axle weight that mandates the use of an 8 or 10 ply tire, although these can be used if additional load carrying capacity or durability is desired. -- marshall@tirerack.com

I currently have P365/60R18 tires on my 2007 Dodge Durango SLT 4 wheel drive with the 5.7 hemi. I tow a 28ft. travel trailer during the spring/summer/fall camping season. The tires are due to be replaced. Would an LT tire be better suited for my vehicle? Would they last longer and give better handling when I am towing?
