Tire Pressures in TV

[billcf7]

Looks like your tires are DISCOVERER® AT3 XLT™ the only ones in that size. The chart shows as follows
LT325/60R20 126\123R E RWL 9 - 12 9.5 13 35.35 70 3750 16.5 no weight chart, This is all they say about pressure
The inflation pressure indicated on a tire sidewall is the maximum pressure allowed for the tire. It is not intended as a guide for normal inflation pressure. The proper inflation pressure continues to be what is clearly stated in your vehicle’s owner’s manual and/or on the vehicle placard found on the driver’s side doorjamb, glove box or fuel door.

Except of course when the vehicle's placard for the tire pressure is higher than the tire's maximum pressure rating as listed on the tires. In that case you don't want to go by the vehicle placard as you never want to exceed the maximum pressure that is stamped on the tires.

Well made it to GA campground- no issues. Thanks everyone for chiming in on opinions and experiences

[citgodan]

Yes, with 65 psi, it does feel better than 80. I may look into the coopers again when refreshing

The tire pressures listed on the door jamb remain correct if the new tires are the same size as the originals

What is proper? Load sticker on truck, or tires?

man, I am full of questions this week!!


Thanks again in advance.

Towing does not change the tire pressure requirements. Use the numbers on the door jamb and be sure the tires are cold before checking/adjusting pressure. If the morning sun has been shining on the tires, they are not “cold.”

I agree. LR E true LT tires in my experience run max 80 PSI.

My Ram 2500 listed 80 lbs on the door pillar I think, but that was for maximum load carrying, so sometimes if I knew I wasn't going to be towing/hauling, I'd lower them to 65 for a better empty ride.

Look up those specific tires and see what their max load carrying capacity is.

It may be an E rated tire but I have found the max load of 65psi tire is less than an 80psi tire. I have seen a manufacturer, manufacturer both.
It is time to hit the cat scales and see how much weight is actually on the front and rear before I move to a 65psi tire.

Michelin Defender E-Load 80psi pulling 2016 Whitehawk TT. My TV is a 2008 5.7 ltr. Tundra. From the Great NW, Lakewood, Wa. Have a safe trip. I highly recommend our tires!

We also replaced the OEM Transforce with Michelin Defenders. Very happy with them.

after a lot on miles and years towing I have found the door jamb usually shows comfort numbers, i always air to max that the tires can take when i am loaded, 65 may be a little smoother riding but 80 lbs will handle more heat-to low pressure will cause more blowouts than 80lbs and tires will wear better when loaded
Heat is a major factor and will blow out a lot of tires, air to max and have no worries

Load sticker on Driver's door jamb is often= Tire Max for Truck BED, and something less than sidewall Max for steering tires (for better driving). Go by label on jamb, and you are then ready for LOAD.

I run Cooper AT3 295x60x20 load range E on my RAM 3500
Follow the cold PSI rating as noted on the tire.
I run 80 PSI towing and 75 or so when not towing.

No the door jamb shows 275/...... so I know the owner switched them out for a wider 325 tires and used. the truck is '18 and the tires are 34th week of 2016.

Before I go back to GA again in October, I will def buy new ones, but would like 275 width if I can get them at 65 psi if available.

I aired the front tires to 63 and the rear to 65. I watched the temps during the trip. the front maxed at 67, and the back maxed at 71. this was cruise control set @ 70 for the 4 hr trip.

My tire shows max. load single (3750 lbs) @ 65 psi. Tread 1 ply nylon +2 ply steel+2 ply polyester. Sidewall 2 ply Polyester. Made is U.S.A.


I can't really find much info about the actual tire.

The confusion lies with the width of the tire. Load range E tires wider than 295mm have a maximum 65 PSI pressure. Always follow the TIRE manufacturers recommendation on tire pressures. Vehicle manufacturer's ratings are for the specific tire supplied with that vehicle.

we have endurance E range tires on our new 2021 white hawk. First thing I noticed is the tread depth is almost none compared to any tire I have used. chevman

Maybe true, but I had my set for 4 years, they wore even and no issues. We camp every other weekend from Oct thru the beginning of May every year here in FL, so they had some mileage on them. I can't complain. They may have lasted another year, but would rather swap out.

[ErikB]

I’m getting nervous too! Our new to us last November Greyhawk came with a brand new set of Firestone Transforce HT2s! Most Forum posters seem to tout Goodyear Endurance! Sure hope we don’t learn a lesson the hard way! One positive is we don’t presently plan on wandering too awfully far from home. Otherwise, what have you all experienced on selling almost brand new tires in the event I consider changing them out right away?

We have 12,000 miles on our set of Endurance in two years and only have 3/32 of tread left. Very even wear but when you only have 8/32 when new that doesn't leave a lot of tread if you travel a lot like we do.

Al. Thanks for that info. The Endurance reputation for reliability has been good but the tire wear doesn't look so good.
