275/80R22.5 16PR H Uniroyal RS20

June 03, 2020, 05:22:02 pm

After too much reading I've decided that the 275/80R22.5 16PR H Uniroyal RS20 @ $398 each delivered. Would be a good fit for me. I like the fact that they are rated for off-road use and I do believe that just rolling over a rock can cause damage that will stay hidden till the worst possible time. I don't expect these to have the real nice ride, but fit into a more utility category. If anyone can add more information I would prefer to learn from others who have spent money's and can comment on the actual ride and life of these tires. Toyo m154 looked real good also. Was planning on 16 ounces Truck tire bead bags and on site installation was about 50$ per tire. If I drive to there shop it is 30$ tire. Think I prefer to get done while I work on the rest of the coach.

We have them on our U300. Currently have 15K miles on them....Great tire when warm....abit sluggish when cold....however no tire checking like the MIchelins we came from.....Buy them...!! Chuck in TX likes them also.

I don't see what kind of Foretravel you have. We go off road all the time in our U300 with 295/75R22.5 with a brand mix on the rear and never have have a problem with rocks on gravel or dirt roads. No highway howl either.

Their max load single is 6610. Our 7160 Xza 2'a required 107/97. Our XZA-3+'s 7610 rating means 97/87 pressures.

Those on our coach would need 117 and 107. Not good on our concrete block freeways.

Smooth Asphalt roads? Probably less of a problem.

What does your coach weigh on the front axle? You have 13,220 capacity available at 120.

Driving the Santa Ana freeway yesterday reminded me how much I liked the lower pressure front tires. Hardly noticeable that the road had concrete block bounces

Not wanting a tire brand war but this is probably a better fit for keeping the front axle weight in check.

Scott,

We installed that same tire (set of 6) 2 years ago. We have been perfectly satisfied with the performance in all respects. Since I could not be any happier with a set of tires, I don't see what spending more money (on Michelins?) would have gained me.

Our coach sits outside in our driveway when not on the road. We don't have a cover

so the tires get exposed to a lot of hot West TX sun. I am happy to report, after 2 years of this abuse, none of the tires show the slightest sign of cracks or checking.

I will heartily recommend the RS20 to any coach owner who asks for my opinion.

Link below to my original report on the tires when we had them installed:

Here we go.....

Don't know what tire chart you are using, BOB, but according to the official Uniroyal chart the RS20 max load single is 7160.

The posters link has it at 6610 maybe a mistake there.

When we bought our coach from MOT in December of 2017, it had six new RS20's on the coach. I have zero complaints. I don't drive in any snow or anything but they perform well.

Nope, BOB is correct. Just went out and checked the sidewall on our RS20 tires. Max load single is 6610 at 120 psi (cold).

I will remove my post (above) with the incorrect tire pressure chart so as not to confuse future readers.

Don't know what the deal was with that other chart. When we bought our tires 2 years ago I went online to the Uniroyal tech page and copied that chart right off the site. Strange.

Smooth roads. Within capacity. Great. Bad roads? Bad roads maybe not so much.

Drove our Xsa-2's at full pressure on nice roads. Great. Bad roads? Terrible.

Lowered pressures. Same on good roads. Directionally better. Bad roads much better.

Changed shock adjustment twice. Less roll stiffer. Worse ride on bad roads

Changed to FSD's. Wow. No sharp edge kickback. Same or better roll resistance

Went to xza-3+'s at 107/97 better from newer design. Steered

Going from G to H seems to add 1000 lbs capacity for each tire and another 15 psi out to about 125 psi in a 295/75. This is probably going to cause a harsher ride. Some tires have "rock ejectors" built into the tread pattern. At 110 psi on our G series, the ride is fine most of the time.

Pierce. I've personally had tire issues with overloading and tearing/failing steel belting. Have read that the small sharp hard rocks damage the belting. All these tires failed statically. The RS20 were designed and protected against that type of damage. I'm just trying to get the most bang for the buck. The little town this is located in doesn't carry much selection. Hercules and double nickel. Just trying to get it figured out before we leave to inspect. Craneman again finds flaws in my judgement too which I really do respect. Max single load really could be higher. I actually had originally looked at the M177 but was hoping to use the same in all positions, wish I could explain why, but I'm thinking that may be flawed on my part. I really do like the idea of the 295-75R 22.5 for the extra inch of width. I'm not concerned about rubbing. This is exactly the information in need. Thanks for the input

Scott,

Did you mean double coin instead of double nickle? We are up for new steer tires this year so I have been calling around to the big dealers for input and prices. Double Coin tires get good reviews and placed second after Continental in a tire test Continental-Double-Coin-truck-tires-score-well-in-fuel-economy-test

Reading some forum reviews, users seem happy with the tires and especially the fuel mileage.

As I said, we have older Coopers up front. They have a lot of small cracks developing, enough that considering their 11 year age, think it's time to change them out. In the back, we have Firestone/Bridgestone almost as old. The Firestone/Bridge looks like it was just put on with not even a trace of the smallest crack. Bridgestone casings are rated for a max of 15 year casing life for recapping.

What kind of tires did you have that came apart? Our Coopers in the front have quite a few of small chunks missing. The rear Firestone have none.

Also heard good things about the GreenMax, a tire made in Thailand. Here is a good idea of prices and lots of truck tires from dozens of manufacturers. https://www.ustireoutlet.com/products/

I had 6 RS20's put on at MOT when I bought it 9/17, had trouble with one on the front (1/18) and had toyos put on the front because the tire shop while on the road was out of them, but the 4in the back no issues. Uniroyal rep factory defected it and did me right on compensation

Can you have them verify the DOT "build date" before they ship? You want 6 fresh tires, all with same (or close to it) build date.

Can't be too careful with tires. Bought a used Newell from Parliament coach in Tampa and had them put on a new set of Michelins. Drove home and found out the new tires were 10 years old! Took a couple months but had Parliament replace them in my town. They wanted me to drive 1500 miles back to them and I insisted to have them replaced locally. Found out later the tire stems had not been replaced after having one replaced on the road had them all replaced once back home.
Had MOT put new tires on another Newell I bought from them and specifically told them to have the tire shop replace the tire stems. Nope, had 2 tires leaking while we were loading into the new coach. Back to the tire shop for new stems.
I watched the guy mounting the new set on my FT after verifying myself the DOT dates. No problems!

Scott, in reply #11 you said "I really do like the idea of the 295-75R 22.5 for the extra inch of width."

By "extra inch of width" did you mean that the tread on the 295-75R 22.5 is one inch wider than the tread on the 275-80R 22.5.

I carefully measured the tread width on several different manufacturers 295-75R 22.5 tires and compared it to 275-80R 22.5 tires. There was no difference. I asked a Swab tire guy why 295 verses 275 and was told that the 295 and 275 are the width of the tires at the widest point (the side wall) and that 295 tires (Toyo and others) have a bigger bulge than 275 tires (Michelin), but the tread width and outer diameter are the same.

Wyatt. I was under the understanding that they were wider. I will look into them father Really looking for the best bang for the buck. Think with the higher single load rating would help to be a bit more conservative and allow possibly lower pressures. Still trending towards the M170. Any further input is greatly appreciated. Was swapping internal TPMS Sensors in my toad today and am actually thinking on installing The M170s myself. If done lots of tires up to 18 inch and the Utube makes them look within my means.. still really liked the Uniroyals RS20s off road rating, but the Tokyo's are at the top of my list. Thank you

Forest. Unimaginable. The ethics that our children's children Show do not represent ours. Do a good job, charge a fair price. Words for a time passed. Everything goes full circle. I did take possession of the new rebuilt Napa dryer today and gave a quick thought of you. This has been a huge project and I haven't even personally even seen the coach. Priced right but un-operated for many Many years. As I've said before worst case we take our parts and run, and I do mean run as fast as we can away. Thank you for your shared past wisdom. 10 year tire as new. Unimaginable!

I think you'll find that the only tire that will allow lower pressure for your axle weight is Michelin. Look at their inflation charts and look at Toyo's. I'm not affiliated with Michelin and I have had some problems in the past with premature weather checking on their sidewalls, but if you're interested in a softer ride then I would recommend them for steer tires.

Like that you call them Tokyo's.

You are not buying tires for a sports car. Unless you plan on entering autocross races with your new coach, I seriously doubt that you would ever notice any "handling" difference with 1" more or less tread width on the steer tires.

Aside from handling better, all things equal, wider tires stop faster as there is more "meat" on the road. The taller the coach is like a U280/U300, the more it will seem to move around in crosswinds, bad roads, construction zones, etc. with more flexible sidewalls. Newer drivers of these coaches may try to chase the feeling with steering inputs until they get used to it. One of the reasons I like a stiffer sidewall in our tires.

Last year, we replaced the tires on our ML320 with the larger and much wider optional size. About two months ago, a bus going the other way on a boulevard ran through a red left turn light at high speed and a high speed collision seemed certain. Max braking with the ABS with all dogs flying to the front seat made an impossible stop perhaps 6 feet before hitting the bus midships. (Atturo AZ800, best tire I've had on a SUV)
