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.

can i put LT tire on my Jeep 2011 Grand Cherokee

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.

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?
Thursday, March 14, 2013 by colin:

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
Friday, August 22, 2014 by Tire Rack Team:
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.
Tuesday, September 9, 2014 by Tire Rack Team:
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. --

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. --
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. --

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?

I have a 2001 Jeep Grand Cherokee Limited 4x4 V8. It is standard with no lifts. It is OEM P235/65/17 and I would like to plus size 1. What difference will it make, what tire options do I have within plus 1-2.
I travel 75% - 80% Highway (+-)and 20% (+-) as a defensive shooting instructor, wilderness survival instructor, SAR Ground team leader and Scout leader.

Been looking at Firestone Destination A/T (for ride/ noise ratings) for the used 2000 Ford F350. While it has the towing/camper package, the most I'll use it for is moving firewood. In this case, are LT tires necessary?
Tuesday, December 30, 2014 by Tire Rack Team:
Pierce, When sized appropriately, tires in 18" or larger sizes can work just fine on the Jeep Grand Cherokee. If you wish to plus one and move to a larger wheel size, the appropriate size is 255/55R18.
Monday, January 5, 2015 by Tire Rack Team:
Jim, Regardless of the truck's use, LT tires are required for your 2000 Ford F350 due to its weight and load carrying abilities. --

I just replaced my 2005 Durango's 245/7017 tires with LT265/70/17. The Durango is very light in the tail and thought the extra weight might help. Will this extra weight strain my brakes, wheel bearings, and other parts and make them wear faster? Thanks

I have a 2012 Nissan Armada with 265/70-18 Conti's. I tow a travel trailer, weight approx 6500#. Conti's squat a good bit even with weight distribution hitch. LT tires sound like a good idea? I figure they wouldn't bulge as bad. Not concerned about the stiffness in ride - have plenty of wheel well clearance.
Tuesday, February 3, 2015 by Tire Rack Team:
Larry, LT tires will reduce the amount of squat you are seeing and also allow a higher amount of load carrying capacity. The downside with doing this is ride comfort (which you have already addressed) and the increased purchase price of the product. --

Hi there. I got few different answers for this question. i'm looking to buy 31x10.50x15 tires to put on my stock 15x6.5 wheels. i noticed in one of the answers, a person was advised to run a 31x10.50x15 without any rubbing issues. the rubbing part is not the issue for me, but is 6.5 width ok. I realize that 7 inches width is the minumum size of wheel required for such tire. just dont want to spend extra money on wheels. but if i have to ,i gues iwill. thanks.
Thursday, February 12, 2015 by Tire Rack Team:
Ray, The 31x10.50R15 does require a minimum of 7” on the rim width, so you may need to purchase new wheels to accommodate the tire size you’re interested in for proper fitment. --

Hello, I have a 2006 Ford Explorer Eddie Bauer. The tires it currently has on it are 245/65/17. I am having a leveling kit installed on it that raises it 2.5" in the front and 1.25" in the rear. Would 265/70/17 tires fit without rubbing and would I need a P or LT tire?
Wednesday, February 18, 2015 by Tire Rack Team:
Austin, P-Metric tires are best suited for the Explorer. Your request seems reasonable give the slight lift/level, however we cannot gaurantee the fitment of larger tires on modified vehicles. --

I have a 2013 Ford F-150 STX with P265/60-18 tires on 18x7.5 rims. I will be towing a gooseneck (bed mount) trailer that when loaded will be just under the max towing limit for the vehicle. Should I go to an LT tire? If so, what size? Also, the stock tires result in the speedometer reading 64mph when true speed is 65.
Thursday, February 26, 2015 by Ray:
I have a 73 gmc 3/4 ton, it has LT tires on it now. I lowered it and would like to put 245/ 75r16 p tires on it. Would that be ok if I don't plan on towing or carrying a heavy load..
Friday, February 27, 2015 by Tire Rack Team:
Art, An LT tire is appropriate when hauling a gooseneck trailer. Many people have good success using a 275/65/18 tire size which allows for a bit more tire selection and additional load carrying capacity. --
Tuesday, March 3, 2015 by Tire Rack Team:
Ray, For safety and liability reasons we cannot support the use of a P-Metric tire on a 3/4-ton truck.

I have a 2015 AWD nissan rouge. I know it is an crossover not a suv. Can I put the light truck tires on it when they are due? I can get 225/65R17 in either. I get the stiffer ride. That is not an issue. It is mostly for the better wet/snow all season tires. Road noise would be the tread. I had BFG long trails on other SUVs in the past with no issues. Was thinking the same for this one later on.
Tuesday, March 3, 2015 by Tire Rack Team:
Erik, We do not see an issue with using a highway all-season truck tire on this model as long as the tires selected meet the speed rating requirement for the vehicle. In this size, there is a mix of selection that is appropriate in both the Highway All-Season and Crossover/SUV categories. --

Can i use p tires on my 99 yukon?
Friday, March 6, 2015 by Tire Rack Team:
Andy, P-Metric or Eurometric tires are most appropriate for a Yukon or any 1/2-ton truck based application. The use of LT tires will result in superior load carrying capacity, but decreased fuel efficiency and a stiffer ride. --
