Upgraded Wheels and Tire Pressure

[55wed55]

I have a 2011 Crossroads Cruiser 5th wheel that has the optional alloy wheels. I'm looking to purchase new tires and thinking about the Goodyear G614 RST. I currently keep my tires at 80 psi but the G614s recommend 110 psi. Does anyone know if my current wheels are rated to go that high? I've looked all over the wheels and can not find anything stamped on them about max psi. All I find is: Max load 3200 lbs. Made in China, M AGF, 8F131, 16x6j, 07 30 988.

It seems to me that they aren't rated that high. I replaced mine with LT tires and had to replace with larger wheels and (if I remember correctly) higher rated as well. You can find the wheel rating on the wheel, usually in the most awkward spot they could find. Maybe someone else can give a firm answer but since most manufacturers install the lowest rating of tires/wheels/axels they can legally get away with, I would suspect you need to upgrade.

I put G614's on my 2012 Redwood 36rl on stock 16x6 wheels,after about 15k I noticed that I had 2 cracked spokes on 1 wheel and 1 cracked spoke on another wheel. Goodyear commerical tire dealer said the stock wheels are not heavy enough for G rated tires. My stock wheels were rated for 3600lb I went to a 3975lb wheel. My trailer weight is right at 16k road ready. I run my G614's at 100psi they have 45k on them and going strong.

If you go with the G614 I would absolutely not put them on your stock wheels.

Well, I replaced my tires with Goodyear Endurance today. After research and help from this forum, I decided not to trust my wheels at 110 psi. I didn't have a lot of time since we are only in this campground for 4 nights. Found a Goodyear dealer just a couple of miles away. I didn't even have to break camp. I removed the wheels two at a time and took them to the dealer. Hope they last.

After a tire disaster trip a couple years ago, I switched to the Endurance too. No problems since!

You’ll be happy with the Goodyear Endurance Tire’s. I know I was. I purchased five last year, one for a spare.

After watching this forum and some outside research I'll be replacing the china bombs that came with my trailer (used) to Endurance. The next question will be "Do I upsize them from 15's to 16's?".

...and from what I'm reading if you have aluminum rims you want the higher PSI tires (80 psi and above) or did I read something wrong?

We don't know what you have for a trailer, so it's hard to answer that.
If you put the-- make, model and year of your rig in your signature it will help with answering.

I think Goodyear should be paying us for promoting their GY Endurance tires. I've seen more people switch to GY Endurance tires in the last year than any other year.

I'm presuming that you were referring to my post. I thought I had already updated my signature... in case it doesn't show up:
Trailer: 28' Rear Living 2014 Cruiser Aire fifth wheel
Truck: 2017 Ram 2500 4X4 with 6.7 L Cummins Diesel.

Mfg sticker says to use: ST225/75R15D after some review I found that the weight capacity of the tires is real close to the Gross Weight of the trailer. If I go to the same size Endurance that delta is increased.

mdbeck1 Your latest post now shows you TV and RV info.

Increasing the tire pressure increases the harshness of the ride. The factory tires are a combination of ride quality and carrying capacity. As to the tires rated close to the GVW of the camper the tires carry a portion of that rating the rest is carried on the truck. Also increasing the load capacity of the tires does not change the capacity of the springs or axles. Lets say the axles and springs are rated at 3500# x 2 = 7000#. Putting on heaver rated tires wont change that rating.

Also if you do change to a larger tire be sure to check for clearance. A friend put on larger tires to try and level the camper to the truck and coming out of a gas station with a dip tore up the finder skirt.

When I replaced mine I kept the original 15” aluminum wheels. I pulled my wheels and on the back they were stamped max 2830 Lbs. Also, check post: http://www.crossroadsowners.com/foru...-at-14303.html Also check out Goodyear’s load/inflation chart: https://www.goodyearrvtires.com/pdfs/rv_inflation.pdf

[55wed55]

Another question about tire pressure. The max on the Goodyear Endurance tires is 80 psi. Max load on the tires is 3429 lbs. Total weight of my 5th wheel loaded is 11,000 lbs. but when hooked to the truck the axle weight is 8860 lbs. Which is around 2215 per tire. Am I correct to assume that I SHOULD NOT inflate to the max 80 psi?

I'm thinking 75 psi.

Comments, please.

Agreed thanks so much to the forum, I placed my order for (5) endurance tires to replace the shameful China bombs that Crusier put on this large expense

My rig weighs almost as much as yours. I have a set of Good Year LT225/76R16E on it.
I went with 16in. tires because I wanted to raise the nose of the trailer to level it out. I have ample room in the wheel well for clearance.

I have never run 80# of air in them. Mainly because in my opinion it's unnecessary because the trailer isn't heavy enough to warrant the 80# psi. When I bought the tires I talked with the owner of the Good Year shop about pressure. He agreed with me that the 80# psi wasn't needed for what weight was there. I know, others will say that's a no no.

I put these tires on in 2013. There has never been an issue with them.
I'm a firm believer that it's not necessary to run with the max rated pressure if your rig isn't heavy enough to warrant it. Your tires are considered part of the suspension also. If they are pumped up to hard it just makes the trailer ride harder/rougher then necessary.
There--that's my opinion. Take it for what it's worth.

[stormseeker]

I agree with everything that has been said. iMHO, tires are the weakest and certainly the most vulnerable link in the suspension so you can't have two much quality and speed/weight rating. Something that no one has mentioned is that cheap ST tires also have a low speed rating. You may not want to drive 75mph but you're better off driving 65 mph on 75mph tires than 65mph tires. It's alll good as long as you upgrade from the marginal factory tires so you are not stressing them to their max rating. Who knows, maybe higher rated Chinese tires would work. It could happen (maybe). Anyway I say you can't have too much tire an if you are going with an ST tire, Goodyear is the way to go.

[Papa-T]

I took my China tires I took off and mounted them on my 5x8 trailer and a spare. Just use it local. At least I feel I’m getting something out of them.

[Tom Amass]

Wow, great Idea, I have a utility trailer and will do the same thing. Thanks so much !

We put the endurance tires on our 2016 Cruiser Aire rk this spring and it tows 100% better than it ever has.
