What tires to buy for Micro Minnie

[Woodstock-WO]

My current tires are Trail Guide A P 235/75/R15 which came with the RV and have been serving us well.
While I like these beefy looking tires they are dated 4517 - Vietnam. Since they are almost 7 years old how soon should they be replaced? I am also thinking of the coming tariffs. Our Minnie weighs 4000 that is a thousand pound load on each tire. Hence it seems that light truck tires are very suitable. Walmart lists a Trail Guide All Terrain 235/75/R15 109XL for $108.64 and calls it a "priority tire." Another one listed by Walmart is Good Year Wrangler Trail Runner A T All Terrain OWL 235/75/R15 1055 Light Truck Tire for $108.00. Would any of these be a good choice? I welcome feedback.

I recently had a chat with Towne fair tire employee. I wanted to make sure I kept the same load rating (G)as I have now. Not sure I need to but that's what was on there. they have a Master craft tire about half price than Goodyear I have on there now. sometimes I associate cost with quality so it seems weird that there would be such a cost difference. I know different load ratings cost different so just make sure your comparing apples to apples I would say. I'm sure someone on here will have a better take on that and hopefully help.

Which 245/70R 19.5 Tires? - iRV2 Forums

Hi, we just bought a used Class A that needs new tires. After doing lots of research I have discovered that tires are either stiff for commercial use or softer for Class A use, but I can't find any

found this thread on irv2 forum. just for general tire info.

Can’t go wrong with GoodYear Endurance tires. Don’t skimp on the load rating. Damage from blow out or flat can cost more than any savings.

Some confusion here. Post #1 indicated the tires were "P" or passenger type.Post 2 indicated Load range "G" which would be LT type or even full Truck tires. Post #4 mentioned "Endurance" which might be ST type. It would help if the actual tire size and actual truck scale reading for each axle were posted. There should be a Certification label with the original tire size, Load Range and GAWR were provided.

is 4000 lbs your real weighed total weight or GVWR?
If GVWR your personscartyres in XL with 109 loadindex is 1030 kg/ 2270 lbs , already pretty oversised in your tandem-axle configuration.
Even if OEM are yust Standard load loadindex 104 / maxload 1984 lbs , still allowed to carry almost 2ce the GVWR.
and 10% must be on towbar.

So not needed to upgrade to LT , wich I daubt the second choice AT tires are.

But you having XL personscartires on your travel trailer proves those are allowed on TT in US.
Often is assumed that only ST are allowed.

ST225/75R15 Load Range E Trailer Tire 80 psi cold. since upgrading to these tires, I have had no problems. Load Range E Trailer Tire. inflate to maximum pressure cold.

On Winebago site this Micro Mini gives
5500 lbs GVWR and 2 x GAWR of 3000 lbs.
So here axles comfortable reserve to GVWR minus 10% on towbar= 4950 lbs on tires.
Tires they give 235/75R15C , so LT or ST.
LT I found 110 loadindex, ST not found , but probably same loadindex in this 15 inch .
Is maxload 1060 kg/ 2337 lbs AT 50 psi
So assuming you dont overload axles or GVWR, these give comfortable reserves.

But as I stated in former post, that OEM where P-tires is not true, though topicstarter suggests a XL personscartyre to use, so can be to law not allowed in US.
To laws of nature the 109 loadindex XL could do, even if 10% derated , and then still more then 10% reserve to the 3000 lbs GAWR's. Can give better performance on soft underground, also because of AT .

Mayby the tire-specialists know if P-tires are forbidden to law on Travel-trailer.

Sorry for my part in any confusion. I just wanted to make sure that we compare tire for tire when looking at them. I may have misunderstood what the 109XL vs the 1055 light truck tire comparison was. My rig has the G rating and was only using that as an example.

Our new Micro Minnie FLX came with Goodyear Wrangler 15" off road tires. They look pretty sweet. Haven't had it long enough to give a real critique. They came filled with nitrogen. Sounds good, but I have no idea how to put "air" in them since I have no source of compressed nitrogen.

 

[jadatis]

A little offtopic here, but you can fill up with normal air , preferably with a compressor with a vessel.

Then first fill the vessel with as high possible pressure, so water coming in as humidity , condenses, and collects at the bottom, where it can be purged once in a while, so as dry as possible air comes in tire.
But even if a normal compressor , the little extra water wont give dramatic influence on pressurerising.

Example 60 psi filled with 95% Nitrogen, then filled over that 5 psi normal air ( 78% Nitrogen)brings back Nitrogen % to about 94%

So dont risk riding with to low pressure, trying to find a place to fill with 99.9 or 95% Nitrogen, more important is to keep the pressure right.

Good information. Thanks. This topic got me thinking about my spare tire. The RV did not come with a jack. What do people do about a flat? I assume they either buy a jack or pay for roadside assistance from a company like Good Sam.
