wheel rating

[robo59097]

I am seriously considering putting 205/75/15 Maxxis tires on the tt before the long haul to Florida in July. I think for my piece of mind I need to get rid of the Marathons that are on it now to avoid potential problems that may or may not occur. So my question is, I can get a set of Maxxis with a higher load rating for safety but the pressure recommended is 65psi. Does anyone know what the wheel pressure limits are on the stock wheels? I figure this would be easier than pulling a wheel and tire off to look. Thanks

I asked a similar question a few days ago but never saw an answer (yet).

I sent Jayco an e-mail months ago asking for the PSI rating on my TT steel wheels (save removing the tire from the spare to find the rating) but I never heard anything back. I'm in the process of upgrading my tires next week.

I was told a few days ago by a tech at Discount Tire that all steel wheels manufactured after 1995 had to be rated for 70psi minimum. Since Jayco has used different wheel suppliers over the years, I would play it safe and confirm the rating stamped on your spare wheel/tire (many tire dealers will do this for free if you are looking to purchase a new set of tires).

In my case I'm going from a "C" (50psi) Maxxis to an "E" (80psi) Maxxis tire, so I'm purchasing new aluminum wheels. Originally I was considering upgrading to a "D" Maxxis tire, but "D"s" aren't' available, so I'm going with a "E" Maxxis.

You can try calling Jayco with your VIN, they might be able to help you.

That is a new one on me, I've been in tire sales for years and never have seen a max pressure rating on a rim that wasnt over 100psi.

If you have been in the tire business, what are you running on you TT? Also, you running LT or P tires on TV? Just curious, I see all these people upgrading and I have stuck with Goodyear Marathons and P rate Michelin LTX on the TV. No issues yet, but I am sure the day will come.

Here you go, a steel vs aluminumn alloy wheel article.

snip......Many higher end units have aluminum trailer rims that are rated for 110 psi.

I agree..., here is one example of a 110psi aluminum trailer wheel by Alcoa: http://www.aawheel.com/SiteResources/data/files/16-inch%20Trailer%20Whls%20by%20DM%2004.pdf

The 15", 6-bolt aluminum trailer wheels that I'm looking at are all 80psi rated and should accommodate the "E" load range tires that I'm considering. http://www.trailertiresandwheels.com/site/1284278/page/910763

In doing a little research a few months ago I found that some folks were finding that the OEM TT steel wagon style wheels supplied were stamped either 50psi or 70psi maximum, don't recall what diameters the wheels were.

I uncovered by tires yesterday to start getting ready for the summer and stamped on the side of my 2009 Goodyear Marathons was Made in USA. Guess I lucked out with this set!

I had one of the tires off my 5th W the other day and the wheel had 3500lb stamped on the back side. So i'm guessing if it will handle the weight than it will handle the pressure.

Robo59097 - one word of caution - I had Goodyear Marathons with "made in USA" on them, and when I uncovered them this spring, one had blown out (there was a piece of outer wall laying on the ground about the size of an orange, and there was a split in the inner wall where it had been. When I went for new tires, another one had a bulge and was ready to go. All from just sitting there all winter. Bottom line - just because Goodyear made them in USA doesn't necessarily mean you are home free.
