New wheels needed - Montana Owners Club

SparkCV · 05-11-2021, 07:22 PM

Good evening,
I checked the stamp on my current wheels and they are only rated to 80psi. I would like to upgrade to a heavier tire which will require new wheels to hit the 110psi. Current tires are 235/80R16.

Any recommendations on a decent wheel that is reasonably priced. Not looking for anything fancy.

Thanks for the feedback.

Contact Treadit, they supply all of the wheels to Keystone. They may give you a good deal.

If I choose to stick with the 235/80R16E is there a good tire anyone recommends in the 80psi category? Not sure I want to change out the wheels at this point.

You will find that the E range tires will be an issue if you do much traveling. Our 2012 came with the Goodyear Marathons, essentially 'ChinaBombs', and in a little more than a year, had five of them fail, all caught before they did explosive damage. After the last failure, I upgraded to what was an option for our rig, the Goodyear G614. Today, with the new RV standards, even that G614 would not meet the new standards. We are now running the Sailun S637 tire which is a 110 psi tire. If you are going to upgrade the wheels, I would recommend the S637 tire.

SparkCV...the gvwr on that 2011 3400RL with payload is 15740lbs (max). Hitch weight should be 2140+-. That leaves 13600lbs on 4 wheels=3400lbs/wheel. Look at load ratings on tires that can handle 3400lbs to be safe where the rubber meets the road.

I know it is a big expense, but the 3400 is a heavier rig. I am not sure how much you travel, but would you rather spend the money on wheels or repairing damage? That’s how I look at things when I hate spending money. At the very least, travel with TPMS and you will have some security. We had a 3400 as our first Montana, before we knew better, and had LT tires. Our next unit was very similar and we had many tire issues. It seems around 2010 is when tire quality really deteriorated. Since using G614’s and Sailun’s, we have not had any issues. Your axles are 7000 lb rated. Do you really want your tires to be the weak link.

If I had to change wheels to get better tires, I would go right to the 17.5 wheels and tires and put tire problems way behind me.
the 3400 model was the heaviest model in it's time.

Do the 17.5 inch wheels create any clearance issues?

In todays market Keystone would not install anything less than ST235/80R16 LRF on your trailer. The LRF is a polyester cased tire and many consumers will opt for the higher rated LRG which is steel cased. With the LRG tire you could use inflation pressures anywhere between 80 - 110 PSI.

The OEM provider Tredit, is just one of many OEM providers that has wheels for the LRF or LRG tires.

OK, thank you. And can I get by with a newer spare that is of the original ST235/80R16E. Or is it best practice to run a spare of that is the same as the upgraded setup?

**Rondo** · 05-12-2021, 12:55 PM

Chris if you are going to upgrade the four you might as well get a match of those four on your spare also. That way if you do get a flat or tire problem you will match and run true.

When I went from load range E to F, I upgraded to steel wheels since the alloy wheels were 80 psi max.

I have since upgraded to all steel load range G.

What tire are you using with that rim? The Sailun 235/83R16 I am looking at require a 6.5 inch rim.

FYI - I did contact TreadIt and they stated they primarily only sell in pallet quantities. Either way they wouldn't sell direct.

Check the Goodyear Endurance in size 255/80/16. It's an E rated tire, but the load capacity (4088 lbs @ 80 psi) is almost the same as other's G rated tire @ 110 psi. You won't have to get new rims.

rohrmann · 05-12-2021, 08:50 PM

If you are purchasing new wheels, and have the option for 6.5” wide, great, but all the wheels that have come with these rigs have been 6” wide, and we haven’t had any issue for the lack of a 1/2” of width.

Thanks for the feedback. Maybe I am getting things mixed up with all the research I am doing. The Sailun S637T everyone raves about indicates a 6.5 inch rim in their specs. The rims I currently have are only 6 inch and 80psi. So my reasoning is if I want the Sailun tires then I MUST purchase new rims that are 110psi rated and 6.5 in rim width. Am I missing something. http://www.gosailun.com/Content/imag...S637T_1120.pdf

I see what you posted but it doesn't add up. The specs do not match what I posted straight from the manufacturers site. The S637T is the only one in the 235/80R16G and is a 6.5 inch rim. And the rim on the trekwood site that they match with the S637 is only 6 inches. Something doesn't make sense.

And boy, trekwood is really proud of that tire. $417.51 each. Much better prices elsewhere.
