Tire pressure 80 vs 110

Guys,

Please check my logic and conclusions.

Alpine 3010RE Dry Weight 11,580 lbs. payload cap 3420 lbs (GVWR 15K)
Hitch weight 2445 lbs
T09BM rims 16x6 3750@110psi

I conservatively estimate my actual GVWR 1300lbs (will get an actual loaded weight before next trip). Load is setup as evenly as possible, I understand it is not equally divided per tire.

Therefore, 13,000 - 2445 = 10, 555 lbs/4 = 2638.75 lbs per tire. If I build in a 20% excess per tire my magic number is 3166.5 lbs per tire.

I can easily reach that with any of these options:

Carlisle Radial Trail HD (235/80R16E) at 3520@80 psi

MAXXIS M8007 (235/80R16) at 3420 @80 psi

Sailun 637 ST (235/80R16) at 3640@110psi

Is there any adavantage to stepping up to 110psi? It presents a few logistical problems with compressors, etc...

I'm leaning towards the Carlisle or Maxxis and staying at 80 psi, what am I missing?

Thanks,

Bud

Javier is usually dead on. But, if my wheels were rated for 110 I would consider running the Sailuns. You just have to look at a load chart to be sure you are running inflation pressure for your weighed load plus whatever margin of safety over that you need.
For a simpler life the Maxxiss or Carlisle HD would be fine.

Another alternative that you may not have considered is the Carlisle HD 235 85R16 LRF which provides 3960 lbs at 95 PSI. Higher pressure, less rolling resistance and increased load capacity without having to go all the way to 110 PSI..

I'm sort of curious about tht T09 rim size. Did your trailer have a tire/rim options list? All of the LRG 16" steel cased tires have a single rim width of 6.5". Some of that tire's manufacturers put the rim width right on the tire.

Without a vehicle manufacturer's recommended option list your best bet is to go with a ST235/85R16E at 3640# of load capacity at 80 PSI.

Your axles have probably been set at 6300# GAWR (Minimum). If not, there's an error in the specs I'm reading.

Trailer came with TrailerKing 235/80R16E. Data I was looking at was from the sendel website. I'll pull a tire next week and see what the wheel says. Thanks.

Carlisle Radial Trail HD ST 235/80R16 10ply on for $77 each at Walmart. In a world of you get what you pay for, why so cheap? MAXXIS are twice as much. Am I missing something?

The Carlisle Radial Trail HD has been out for just about one year (previous model was the Radial Trail RH). Both tires seem to have an excellent reputation. I haven't seen any negative reports on either on this forum. The low price could be related to clearing "old stock" from the warehouse, WalMart's marketing plan, incentives from Carlisle, changing contracts or some other "unseen reason"....

As for "getting what you pay for" that's usually true, but unless Carlisle is selling "reject tires at a discount" (I don't believe they are), the ones WalMart has on sale are first run, same as you get from Amazon or Discount Tire at a much higher price. A quick internet search shows prices ranging from WalMart's $77 to Pep Boy's price of $149, all for the same tire.

How or why??? Who knows, but there's also an old saying, "Don't look a gift horse in the mouth".... So, if you're looking for tires, think Carlisle RT HD's are suitable for your purpose, WalMart has an excellent price right now....

This is just about trailer tires in general.

I've been tracking trailer tires - any designed used as OEM - for about 15 years.

Recalls for trailer tires are not any more common than for any other DOT certified highway tire.

Every tire design has consumer pros and cons. Some are better than others.

Every tire design has it's good, better and best liked tires.

Every tire design has cheaply made tires that will pass DOT inspection but not be very durable. The cream will rise to the top.

All tire designs are specifically designed for a best function. ie, what is needed in a drive tire may not be required in a steer tire.

Just about all tire manufacturers now provide a warranty package of some sort. It is the best information you'll get about that specific tire from its manufacturer. The packages provide a user/maintenance section. All - in their own words - pretty much follow tire industry standards.

Here is one worth reading if you have them. Because of the industry standards it's worth reading if you are using ST tires from any brand. Note that this particular manufacturer warranties their ST tires from date of manufacturer displayed on the tire sidewall.

http://www.maxxis.com/trailer/trailer-warranty

A Maxxis quote: ◦It is preferable to replace a vehicle’s tires with ones that correspond to the vehicle’s manufacturer-recommended specifications. Tire speed ratings and load–carrying capacity should always be equal to or greater than the original equipment tires.

SOLD! Thanks John. Just ordered 4 Carlisle 235/85R16 LRF. About $100 a piece, I'll get them mounted at my local tire shop. Thanks to all for the advice.

Which did you get The RH or HD? I noticed you ordered 4, what do you plan on using as your spare? Sounds like you got a real good price, not sure what they will charge you to mount and balance?

What type rims do you have?

I also ordered only 4 Carlisle Radial Trail RH 235/85R16 LRF about two years. Really Happy with them

As John said I think you're just looking at a really good price barring some kind of deal they've cut. When I bought my Radial trail HDs last April they were $115 each at CW and $111 at DT not including mounting/balancing. CW matched the DT tire and they had lots of room to do the work vs the DT store is really tight. My tires are 235/75R 15 LRE.

Edit: Whoops! Didn't see that you had ordered the tires. Oh well.........guess my eyes keep moving but my brain stops mid stream....kind of like puppy. At times when she's licking me her tongue just stops for several seconds, like it's stuck to my skin as she just gazes into la la land. Then, all of a sudden it's "plop" and away we go again.

I have the Sendel T09 BM rims (3960@110psi). My only concern was width because my rims are only 6" wide. Research told me I could put them on and local tire guy confirmed.

I ordered Radial Trail HD 235/85R16 LRF. I like the idea of 95psi because I dont have to upgrade my compressor. Walmart has them for $97 each. I have one 1 year old Good Year Marathon 235/85 R16 E that a friend had leftover from his recent upgrade that I plan to carry as a spare. Now that you have me thinking about it, maybe I'll order one more for a spare.

Update. Cancelled original order, reordered five Carlisle HD 235/85R16 LRF tires, picked them up today. All five dated 5216, look great. Thanks for the info on the 95psi Carlisle LRF option, a perfect fit for my resources and application.
