Spare tire on 30RL different than rest of tires

[spock123]

I have MasterTrack ST-235/80/R16 on the 2013 Cedar Creek and they have been pretty good tires so far. This is what I would like to know, it could be me but it just seems odd to me for C/C to put a spare on the camper thats a Goodyear G 614 RST LT-235/85/R16. From what I have found out is this tire cost a lot more than the Mastertrack, I just wonder why C/C would not put the same kind of spare on the camper. Does anyone on here might know why

What is basically different is the sidewall height-to-width aspect ratio. That's the difference between the 80 and 85 noted in the tire size. This is the sidewall height-to-width aspect ratio given as a percent. The 80 means that the sidewall height is 80 percent of the tire width. I would not like to mix them personally, but many people do. I would go back to the dealer and see if they could match them the way they should be.

Whoever delivered it to the dealer may have had a flat on the road and replaced it with what ever was cheaper/est.

I agree with talking to the dealer about a replacement.

I must be missing something here but the master track is about a $100 tire and the goodyear is almost $400.

You're not missing the cost factor but there is
much more. Aside from the aspect ratio mentioned
above, your ST's are trailer tires and most likely
are Load Range E with a 80psi max inflation pressure.
The G614 is a LT tire that is G rated and has a max of 110psi.
There are a lot of other factors that come into play
with the G load. So, if you are going to keep it
as a spare you will have a superior spare.
A little squirt of 303 once a year and it will
last as long as the trailer. If you want to
put it into service, you will need a matched
set. You can damage your running gear if you don't.
As far as why? They had one.

The Cedar Creek site states that Goodyear G614's are standard on 36RE, 36CKTS, 36MDX, 36B4, 38FL models with 7000 lb axles. What model is yours?

I have the 30RL C/C, I plan to keep the spare tire and when I need to replace the master track's I will buy 3 goodyear's. That's what I was going to do all along but I was just wondering why C/C would do something like that. I thought that maybe Tom Johnson may have took the goodyear's off the camper and forgot the spare but the load sheet had the master track's on the sheet. It just seem odd to me. Oh well just one less good tire to buy

[Dave_Monica]

So you got the Goodyear spare by mistake...you should return it to the factory out of guilt!

You should replace the 3 Master Tracks with matching good year's before you have to replace a lot of damage parts when they blow.

Just keep in mind that the Goodyear tire has a 110 psi rating, that doesn't mean that your 4 factory installed wheels mounted with the Master Track tire are rated for 110 psi.

Kind of goes back to that old saying about a chain is only as strong is it's weakest link.

I don't know much about tires, so how do you tell if you have the wrong wheels for the goodyear's. I have nice alluminum wheels on the camper.

[jonrjen]

My understanding is that is should be stamped on the backside of the wheel, however on the wheels that came on our Wildcat 353LS I was not able to locate the PSI rating. The stamped weight rating per wheel on ours is stated 3200#. Our 5th wheel has 6,000 axles, I'm not sure what you have on your trailer.

Thanks, I will go under camper and check it out, I think I have 6,000 axles on the 30RL.

You don't have to run 110 poundsbut good year is the only company that pays for damage when you have a blow out

Your axle rating will be posted on the yellow DOT sticker listing tire size and weights that should be on the street side of your 5th wheel near the front lower corner.

I checked out the axle rating and it was 6,000 lb, I also got under camper and this is what I found, the rims are made in China surprise, 3200 pounds was stamped on the rims.

[jonrjen]

I couldn't find a PSI rating either. I am just assuming that with a 3200# load rating that the max PSI would be at either or below 90.

You could run G rated tires on the wheels, but the weight that the tire is rated at will be far above what your wheels are rated at. You can also drop the PSI that you put in the G rated tire, which will also decrease the load capacity of the tire. I would also allow for sidewall flex which would allow for more heat to build in the tire materials.

Of course the G rated tires are built much stronger as far as tire construction and number of Ply's.

Someone mentioned that Goodyear would cover trailer damage due to a blow out, but could they also deny to do this if running the tire under the proper PSI?

It can become a vicious cycle as to the right or proper route to take. Best advise I could give is to read the many post of tire choices, manufactures and selection available in your market. I know my tire guy who I trust pretty much gave me this same advice, because your not going to find a ST specialty trailer tire made in the USA. And it seems that the quality of imports can be all over the spectrum from manufacture to manufacture as well as quality control with in all the manufactures.

But if you keep your PSI set correct, stay within the speed rating of the tires, keep them covered when parked to keep the sun from baking the side walls to a cracking or dry rot situation the OEM China tires may do the job you need them to do...for awhile.

I guess my suggestion would be to buy what you think is best, keep all the sizes the same, try to stick with all tires and tread patters being the same, then what fits into your budget and carry a very low deductible on your insurance.

[spock123]

Oh one other thing, what speed should I be going with these tires. On my trip to Yellowstone there were a few days that I was running 80mph, mostly 65 but a few times more.

[jonrjen]

Most all E-rated ST tires are a max 65MPH.
