tires

If you have different tires front and rear, you can't rotate them.

I always put the same kind of tires all the way around. Trailer towing presents enough white knuckle situations, why add to that with mis-matched tires? Good handling means a more relaxed trip.

I wouldn't do it because your spare is still a P tire, so if you need it on the back you'll have one P and one LT...if you're replacing the tires a pair at a time and doing the rears first that's a different story.

What does the vehicle tire placard say about the original tire size and pressure? We need that information before any advice should be given.

Good grief...folks have ran P tires on front and LT on the rear even when all tires were bias ply. Radials are no different. Now mixing bias and radials can create dangerous handling issues.
The P tire in front and LT on the rear will not create any issues if you run the P tires at max 44 or 51 psi which ever the case......and run the LT on the rear at 50-55 psi which is about all many 1/2 ton wheels are rated for.

I've used all season Passengers on the front and bigger/same size LT all terrain type tires on the rear on every 1/2 ton truck I've owned for winter use. No issues.

You may have to jocky PSI a bit find a psi best suited for intended use.

Just get a full set of tires. When I bought my old motorhome it had a set of no-name Chinese tires on it. Of course I had a massive blowout on a 10 lane section of highway in the evening rush hour. I literally thought my wife had a heart attack. It cost me $2700.00 bucks for a brand new set of tires that evening but, I was happy to pay it. What seems expensive now seems cheap when bad things happen.

My point is get a set of tires, all the same, equal to the task, and of good reputation. Never skimp on tires related to RV-ing.

i worked as an auto tech for 25 years
every shop i worked in(including dealerships) sold tires

never a good idea to mix tires on anything
this goes for make.modle and size of tires
also a good idea to make sure tires on all axles have near the smae amount of tread


most people dont realize that tires are part of your suspension and braking systems,but they are

Is it ok to run P rated tires on the front of my ram 1500 while running E rated tires on the rear. I'm towing a 6200 lb. travel trailer. Thank you.

Why - to save money?

I suppose you can run any combination you want but the function of the WD hitch is to transfer some of the tongue weight to the front axle and tires so the TV and TT sit level. Usually that means the same tires all around.

In my case I have had excellent results with the original P tires over the last 30,000 miles of towing. So when it came time to replacing them, I decided not to fix what was not broke. The TV was designed for P tires, so I run P tires.

I do bump the air pressure up to 40 lbs. when I tow. But the DW already thinks The TV rides like a buck board farm wagon, so I certainly am not going to do anything to stiffen the ride.

Some folks feel better with LT's or some other premium tire, so there is no reason for them not to use what they like.

Good Luck

Scary handling comes to mind. DO NOT DO IT!

Are you spending money? Are you just getting two LTs for the rear? s/b fine however when the Ps are done, square it away with LT on the front also.

I would not go much above 50 psi on the LT-E used on a 1500.
