Tire Pressures While Driving
My new 2014 Raptor came with china bombs for tires. I will be replacing them after they are a year old to me. In the meantime my TPMS shows my tire pressures going from 80 psi (cold tire) to around 93-95 psi while driving. I tow between 60 and 63 mph. What is the normal range for psi while driving?
Thanks

That sounds about right in the correct range.
I use 80 psi in my set of four trailer tires on my rolling garage and have seen temps up there after rolling for awhile.
Of course it depends on the outside ambient temps and what side of the trailer is on the sun side.

Don't panic if you see one side temps higher then the other, it might just be the difference between sunny side and shady side of the Trl. this can make quite a bit of difference at time too.

Those pressures seem about right for this time of year but do yourself a favor and get rid of those tires. The tires these trailers come with from the factory are a joke. I just replaced mine (only 300 miles on the originals) with an LT235-85-16 load range G 14ply tire. The new tires weigh 20 pounds more per tire because of more/better material.

I had 3 tires blow in 24 hours. Get ride of the China bombs and get G rated tires. It is not worth the trouble. The pressures are about right for what you are getting.

I am currently searching for the best price on Good Year G614's. Of course I have to check my rims to see if they 110 psi rated. Talk about an expensive tire, but worth the peace of mind.

My China bombs lasted 3,500 miles. I will call Guinness Book of Records to see if that is the record. Then boom boom two went in the same day. I limped to the RV Park on a used miss matched used tire.
Note - trailer tires are not easy to find on the spare of the moment. Stupid me, thought I could unhook and easily find a replacement tire. 4 places told me they could have a tire in 2 or 3 days none had any in stock. I was about to find a used china bomb at a hole in the wall trailer shop...lucky it got me 400 miles driving at 55 - 60 mph.
Now running Michelin XPS Ribs. And agree...good tires weigh 15 to 20 lbs more. I was wore out changing all 4 in a morning. 32 lug nuts off, old tires thrown in the truck, to the shop, wait for mounting, much heavier tires muscled into place, torque lug nuts. By the last tire I was dragging...
If I had a triple axle toy hauler I would only change three per day...lol. But the main point - don't wait too long.

Set your tires at the recommended 80psi cold settings and go rving. I check mine every 30 days to make sure no leaks.

I agree that the Michelins XPS RIBS are the way to go if you can use them since they are only an E-rated tire. On my new 5er the tires are G rated with 7,000 LB axles so it is either Goodyear ST tires or a China ST tire.

I made close to 3000 miles before my 3 blow outs in 24 hours. I went to Goodyear G rated tires. The wheels will take that. I checked with keystone. I maintain 110 psi and continuous pressure monitoring. So far 4800 miles no problems. Do not go with E rated tires if you can help it. Tires are expensive but like is precious.

What makes the tires china bombs? Why replace them if you havent had problems? As you roll down the road, tires will heat up and psi increases just like its supposed to. Dont worry about the increased psi. Worry about the psi when the tires are cold.

Any ST tire in my experience are junk. I will never never have any on my units including my utility 3500 lbs trailer.

Don't think that just going with the G614 Goodyear's will give you trouble free trailering. These tires are almost as bad as the proverbial Chinabombs, especially if your axle weights are over 6000#. If you have 6000# axles and are under that weight, then they may work. If you are running 7000 or 8000# axles you might want to consider going with the 17.5" wheels and 215/ 75R17.5" LRH tires. I have the Roadmaster RM160 Engineered by Cooper Tire on mine with over 2 years and 10,000 miles trouble free. It cost me right around $500 each wheel and tire combo, so only a little over $100 more per tire than a G614 Goodyear. I am not as heavy as some units out there, But I am over 16,000# So I am approaching the 7000# limit of my axles.

The 17.5 wheels and tires are the only way to go if you want to be free of trouble imo !
