Rims load range

[5WRon]

Where can I find what my rim load range is. All the limited docs say is "Rims: 16x6" and Heavy Duty 8 lugs.

We have a 09 BigSky with all the bells and whistles.

Help please because I'm wanting to upgrade my tires to the G rating.

Thanks and safe travels to all,

Ron and Linda

Call Keystone/Montana (on Mon now) and give them your rig's VIN #. They should be able to help.

I also have an 09 Big Sky, a 365REQ. I replaced my rims in the Spring, to run G614 tires. The OEM rims had no rating at all for PSI. I was told by someone at Keystone they would take 85.

We were told from one tire company (the company not a salesman) that the HD rims on the Big Sky can carry up to 115#. We changed our original Carlisle "e" rated tires to the Carlisle "F" rated tires that take 95# psi.. They carry 3960# each which is more than enough for the BS 7000 # axles but do not go over 111 psi when they get hot... We are comfortable with that range.. I just wish we could have had the option of this tire instead of the "e" range that just barely fits the 7000# axles..

Another idea (LonnieB can input on this one) is to take your rig to a trusted, reputable (in that order) tire dealer. They, by law, cannot pressure up a tire over the rim's rating, and I believe they would know how to tell. They may have to take the tire off the rim to inspect it? If so use your spare - don't have to take the entire rig in that way. A phone call might save a trip.

Also, as an aside, whatever is on the door post of your tv is the MAX any dealership will pressure up. I have Michelin LTX M/S 80# tires on my truck. My tire dealer made it plain to me that as long as those 80# were on the front - my door post states 55# front/80# rear - that he would not go over 55# of press at his shop on those. Makes no difference on the tire rating or rim rating. They go by the vehicle mfr numbers.

Ah! The rim PSI Rating. This has come up before and a search should produce results. I even posted pictures and a long discussion. In general, the RIM capacity should be either stamped on the back side of the rim, or on the inside of the rim. If the latter, you will have to take a tire off and dismount it to tell. Use your spare ONLY if it is the same rim as what is on the RV. Most RV's have the aluminum rims for nice appearances, but the spare is typically a steel rim. There will be a considerable difference in their capacities.

On my 2008 3400RL the rims on the inside were stamped at 80 PSI, but there was a sticker placed on the inside that said 110 PSI. After communicating with Keystone and Tredit, it was announced that Keystone wanted the rims rated at 110 PSI. Now, I do not know if they just stuck a sticker in there or actually pressure tested them, or ?????

Good luck.

I have the rig in my sig. and the rims are stamped 110 lbs.

If their trailer is like mine, the wheels are aluminum but the spare is steel, so they may not be the same rating.

You're right, Tom. I was thinking of mine - steel all the way around. If aluminum, I thought they all were 110# by default? Its the steel wheels that are questionable and variable - I think?

My Big Sky original rims and tires were from Carlisle. When we got rid of the tires, I sold the empty rims. There was no psi rating stamped ANYWHERE on those rims; inside, outside, or up side down. Carlisle customer service told me a max of 85.

Maybe it was somewhere in Chinese?

If that's the case, maybe I'll buy a $10 Harbour Freight stamp set and mark my rims 3800 pounds / 110 PSI!

I called Keystone about the rims on my 3400RL and they directed me to Tredit who makes the wheels. I explained that I wanted to upgrade to the G614s by Goodyear and needed to know the pressure rating on my existing rims. They asked me to send them in a picture of the wheels, which I did, and they responded back that the rims are rated at 110#. I did not see any markings on the rim either which is why I called.

Here's what I got back from Tredit....

Those wheels are rated for 3750 lbs and are also rated for 110 PSI. In other words the G614 tire by Goodyear will be an appropriate upgrade. Let me know if you have any other questions.

Trirboy, What year is your 3400RL?

[exav8tr]

I have a letter from Tredit Tire and Wheel that says the TR6 wheel, which I, and later owners have, have been retested for 3750 lbs at 110 psi. I even have the new stickers to add to the wheels, I plan on putting the Goodyear G614's on this spring.
