Tires, tires, tires

Hi All -

I know that this topic is probably like "beating a dead horse" as the euphemism goes, but I am new to RVing and I know that tires are pretty high on the important list.
I just bought a 2011 Jayco Pinnacle (38 ft) with a GRVW of 14950 lbs.
I will be taking a trip in about a month so I want to make sure that the tires are adequate.
They are Commodore ST235/80R16 Load Range E
I know that is kind of low on the load range scale.
Manufacturer dates are 2 @ 2413 1 @ 3912 and 1 @ 4012. I know those are week and year dates.
Thanks for any advice you can give.

Welcome to the forum,

Yeup, that's "where the rubber meets the road".
Recommendations will be varied. I prefer commercial trailer tires on trailers.
Providing your wheels are up to the capacity with HD valve stems.

I've had very good luck with these on a heavier coach <15K & tight budget:
LT235/85R16 LRG 14 Ply Sailun S637 Radial Trailer Tire

If peace of mind is more important than the budget:
LT235/85R16 LRG 14 Ply Goodyear G614 RST Unisteel

Best of luck on your trip,
Be well.

Your trailer is at that point where it's too heavy for an LT truck tire like a Michelin XPSRib because they are only rated to 3042 pounds each. I would upgrade to a higher rated, non-Chinese tire.

Thanks, and I believe that you are correct on that. What about the tires that are currently on my 5er. Are they too light as far as load range?

Your tires are 3-4 years old and not the best, so have them examined at the minimum. I'd replace them, personally. The G rated Goodyear's are great. Trailer tires can also be called LT, so don't let the designation fool you.

Perhaps no one can encourage you to go for it on nearly 5 Y.O. marginal tires.
Pardon our skepticism. The industry has a problem in this area as you noted in op.
We also don't know your travel plans. There is a big difference between 60 miles to the lake lot, and a 3900 mi. cross country journey.
Pack light and keep the speed low. It's always a good idea to weight your full set up in full travel mode.

Most of us will replace G,H,J- LR at 5-7 yrs. with full tread, just as insurance

The last set of Sailun's that I ordered had mfg. dates all in the same month and were 3 months old. The fact yours are a yr. apart is curious. Were a couple already replaced? How about the spare's date? Seems the trailer mfgr. would have had large batches of similar dates.
Having then inspected by a qualified tech might be prudent as a minimum. Don't let them sell you similar. We understand budgets are tight.

Be well.

Tires, tires, tires

Thank you all for the welcome. Being new to this seems daunting, but I guess you experience trekkers it is old hat.
Mtn Treker; Thanks for the good information and advice. One can never get enough of either.
Just to let you know, my trip will be about 1400 miles. Not a short drive by any stretch of one's imagination. The current setup of tires were on the right when I purchased it. So I don't know the history of why the different dates.
I have to purchase new tires for my truck as they are Michelin 's but only D rated. I'll be going to E's.
A little concerned about the wheels on my 5er as they are the aluminum alloy and I've been reading that they can only handle E rated tires. Wish I knew all this stuff beforehand. Thanks again everyone.
