What PSI do you fill your trailer tires to: tire recommendation or other?

Tires are ALWAYS inflated to the PSI stamped on the tire side. BEFORE THE TIRE IS DRIVEN AROUND.

 

 The door label is only for a tire with the same ratings as the new car tire.

Different rated tire ?  You always do the tire rated pressure.

I bought the same replacement tires that came with the truck when it was new, so the PSI is the same.

 

My point is that with truck tires, there is a recommended PSI and a max PSI. With trailer tires, there is only a max PSI.

What is the name of the load a dump truck  carries?   Overload.......... So maximum pressure is stamped on the tire.

I used to inflate to five pounds over the max.  It worked fine,...........................for a few years, until I had to replace two tires with broken belts due to over inflation.

 

Most trailer tires for boats are rated at 60 mph, max, and that would be at max recommended psi.

 

Under inflation will build up heat, an enemy of the tire.  Over inflation risks cord/belt failure.  

 

I over inflated my tires for seven years, and towed at up to 70 mph.  Two years ago I was off on one of my expeditions.  I noticed a vibration from the trailer at speeds over 55 mph.  I chalked it up to a wheel out of balance.

 

During one of my rest stops, I decided to inspect the tires and found one tire that had an odd bulge in the tread.  Changed the tire, and the vibration stopped.  All was well until I got home.  Returning from a local jaunt, I noticed the same vibration as before had developed.  It's a tandem axle trailer, and the other tire on that side had a similar bulge to the one I had replaced.  

 

Stopped at the tire shop and the owner told me that it too had a broken belt(s) due to hitting a pothole or something similar with an over inflated tire.

 

Over inflation cost me the price of two new tires.  I'll cheat on the sixty mph up to 65 mph, but will not fool around with putting an extra five psi.  Going 65 mph when the speed limit is 70 mph is tolerable.  Sixty mph not so much.  

 

But who knows, breaking another couple of tires could change my attitude.

I ordered M rated tires for my boat. Rated to 81 mph.?

We are ready for the road.

Here's a Goodyear chart showing recommended psi for varying load limits.  My rig weights 3450lbs as weighed on certified scales.  I inflate my GY Endurances to 50psi which matches the recommended inflation posted on the trailer.

 

Now that I know about the chalk test, I'll check to see what it shows..

I just accept my limits & have it stored in a rack marina. No more winter animals. Yet      

 

I would NEVER USE the trailer P S I  number.  They have NO IDEA what tire you are using.  It would be a disaster to use that number with quality passenger tires .Like Michelin  tires for a big Caddy.   If the load capacity is correct with a 10 % derating. I do it on all my trailers & friends. They treat the tires just like they are on the rear axle of a big car..   Last just as long... If brakes & wheel bearings are set correctly

I was always impressed with the ride of my 2016 1/2 ton Silverado.  Put 60,000 miles on the factory tires and a fair amount of towing. Just to be safe I was going to replace them this year.  When I pulled up the stats on the factory tire I found out Chevrolet puts PASSENGER tires on their 1/2 ton trucks. ?. I replaced with Michelin light truck tires and although I feel much better about towing, my truck now rides like a truck.?

Maybe you should have gone with a Ford instead!
 

Here comes the GM vs Ford debate…

[MN Fisher]

No debate - just a statement.

I owned one Ford - it was a POS from the start.

My Chevy's have been nothing but good to me.

 

GM forever!

If you get the Z71 package you get the horrible riding Goodyear truck tires.  

[cyclops2]

I dropped Michelin Tires long ago  because they wanted to increase life of the tire. By making them harder said a representative. Soft, smooth riding, quiet, tires are out.  Hard compounds are in.  I checked lots of companies & there were none available. 40 ? years ago.

[TnRiver46]

Anything over 40 should be fine, I accidentally pulled my trailer for years with them at 32-35 before I actually read the label

So true.. You wouldn’t have to buy new tires because the factory ones would outlast the truck.?????

You would think the High Country (supposedly the top model) with included towing package would have come equipped with truck tires.

No debate with me.  I’m not brand loyal, I buy what works for me.  I drove a King Ranch Ford, a 1794 Toyota Tundra and  top of the line Ram before I got my High Country Silverado.  I had reasons for liking and disliking each and every one plus dealer shenanigans and trade in values on my 2004 3/4 ton steered me.  I got employee pricing on the Chevy which brought it down to the other models plus they gave me much more on my trade in.  I know you were just joking on the debate but some take it pretty seriously. ?

[J Francho]

They probably assume that the upscale model buyers want ride comfort over utility.  I'm not surprised.  There was some sporty package deal when I bought my truck that featured 22" rims with low profile summer tires.  Looked pretty dumb to me, but I don't even like trucks, so maybe my taste is off.  If you want a sport car, get a sports car.  If you need a truck, get a truck.  Don't try to merge the two, lol.

It stems from the constant flak that my Father and I give each other.  He is a hard core Chevy Silverado guy and I am a Ford F-150 guy.  So when I ride with him, I say "sure is a rough ride" or something smart like that and when he rides with me he'll say "are we gonna make it there in one piece?"

Agreed.  I bought my 2004 3/4 ton brand new and it obviously had truck tires on it from the factory.  Funny thing was it rode really well even after I put Michelin load appropriate tires on it after the stock tires wore out.  I’m not so wrapped up in ride quality that I’m going to do any more modifications like some of my friends have like Bilstein shocks etc., unless they wear out and I need to replace them.  I kinda chuckle every time I look at the dash and see the electric brake actuator thinking I’ll never have a trailer that big.  I pulled a 4 horse trailer with my 3/4 ton and loaded, that was all I ever wanted to tow in weight.  ?

[J Francho]

I'll be honest, if I get another GM truck, it will not have the Z71.  Too much wheel hop, and the ride sucks no matter the tire selection.  With Cooper Adventurer A/T it's a very capable truck in all snow, rain, or mud conditions, though.

I agree. I think I may have one of the last single cab stick shift trucks on the road 

 

the ones I pass all day are 4 door jacked up with knobby tires, just wearing down the treads on the highway

Sounds like the fun my friends and I have. I’ll park next to my buddy who has a dodge truck with my Chevy. When I get out I’ll pour some water on the ground by his truck and then announce that I’m sorry I park next to his dodge because I just scared the pee out of his truck.

[volzfan59]

I fill mine to what is on the tire, always have. I've never had an issue to this point.

Never been brand loyal but when I went shopping for a new HD truck last year it became obvious that Ford was well ahead. 

Ram had cylinder deactivation in a HD truck.  ??? No way.

Chevy Only had the 6.6 in gas offering with 6spd auto.

Ford had the old school durable pushrod engine that out spec'd the others, the 7.3 with 10spd auto. 

I've got 10K towing miles And been very impressed with the 7.3
