Looking for a good 255/70r22.5 tire

[allan5oh]

Big mish mash of tires on my step, looking to replace them all and start fresh some time soon. Michelin doesn't seem to make a suitable tire, so I'm looking at Goodyears G104 RST(which seems to be the only trailer specific tire in that size):

Goodyear Commercial Truck Tires - Unisteel G104 RST Details

According to michelin fuel savings calculator, it has a respectable rolling resistance. It's also the only truck tire I've ever seen rated for more then 75 mph. I'm wondering also if I could just use 275/80r22.5's. Save me a lot of hassle. I'll dump the trailer next time, and see how much clearance there is. The difference between 275's and 255's would be about 1.5 inches radius. From what I hear, 255's can be very very hard to find in Canada. Not only that, they need 120 psi compared to 275's 100 psi. That makes the 275's easier to fill with the truck. On top of that, the 275's all seem to have lower rolling resistance. Especially the XTA energy.

If I switched to 275's is there anything I'm missing other then clearance? I know the deck height will go from 42" to 43.5" or so, but from what I hear that's not an issue at Payne. Could always switch back in the future.

Not familiar with the specifiks, but that's definitely what i would do, if it's at all possible.

The more I think of it, the more it makes sense.

i'm using the Firestone 255/70 r 22.5 16PR, T575 LP on my step with real good results from abrasion wear on the spread. I like the wider groove, so rocks don't get stuck in the tread.

The other tire firestone has thats comparable is the T559, the groove is smaller and should have a lower rolling resistance, and it has the buttressed shoulder ribs, also with abrasion resistant rubber.

I use the 255's on my step deck. I have used Bridgestone, Cooper and Ching Ching's. I prefer the Ching Ching or Cooper. They are half the price and wear just as well if not better. T pay $189/US. The Bridgestones cost over $300 on national account, as I recall.

Not that it makes a huge difference but you should only gain .75'' because the tire will push the axle up from the bottom not the top. So when you drop the air on the trailer you'll only need.75'' more than you have now.

[allan5oh]

That was already taken into consideration. I dumped the air, and there was about an inch. Not enough.

I found this article about Chin Shin tires, of course they weren't for a 18 wheeler, but should make you think twice.





Chin Shin / Greenball trailer tires
I purchased 4 tires 3000 miles ago for my 2004 Terry Travel Trailer, during that time I have had 3 full tread seperations, the most current caused heavy damage to my trailer. I just received a call from the importer stating they were denying any claim. They , without research, claimed the tire suffered a full tread seperation due to heat, I was in a rain storm and traveing at 54 mph and had the proper inflation (I check them every day of travel), They didnt bother to reaearch any of that. Their mission is to deny any claim.
My recomendation to anyone buying any tires for any vehicle you own --is to research where that tire is made (China, Tiwan, Japan they don't relly care )and what kind of customer care and service has been reported. You might find , as I did, they dont care, They dont even put their name or country of origin on the tire, they dont want you to know! Wake up , and try to cure the problem before we have no choice, ask Mattell or Purina how their problems are comming along, if those countries dont care about our kids or dogs , do you think they care about or vehicles or trailers,, certainly not. Do your homework and research before you buy, I will in the future, I will throw these away any buy some GOOD tires.

I wouldn't run Chinese junk rubber on my truck, In this world you get what you pay for.

Been running spreads for years and have tried just about everything out there.

I've had my best luck and service out of:

Firestone FS560 - Pretty expensive tires
Sumitomo ST738 - Slightly, ONLY Slightly less expensive.

But both tires give me over 100,000 miles on the rear axle of the spread, which is pretty damn good.

Put on 2 Goodyear drives that were nearly new. Put them on the rear axle and got about 10,000 miles out of them! Guess drives just don't work back there!

I buy tires from Magnum Tire Corporation - they ship free if I buy 8 at a time and give me 3 to 4 months to pay for them. Monthly payments of course. You might give Joe a call there, he's in Minneapolis. His number is 651-631-4500. Tell him Goodyear Trucking sent you.

I agree, plus remember you get NO casing credit on China tires, so you have to add in the 50 buck or so casing credit to the cost, one road call on a china tire and you loose any savings you think you had.

China tires are garbage.

I have had problems with Goodyear standing behind their work. They don't. The only tire that has stood by their work is Ching Ching made in China. It is the ONLY one whether made in the U.S. or not that has stood by their work. Actually, it was my distributor who made good on the tire. I had a problem with 3 Goodyear tires that should have been warrantied. They refused. That was about 10 years ago. I haven't bought a Goodyear tire since. Most of these tire companies won't stand behind their tires. I don't want to buy Chinese tires but they are at least 1/3 cheaper than those made here in the U.S. I figure that even if they don't stand behind them that I haven't lost anything. If U.S. tire manufacturers stood behind their products the way they should and reduced their prices I would be more inclined to buy them. I can buy a new Ching Ching, Cooper or a few other brands for $189 from my distributor. That is a 255/22.5 tire. I have bought 2 Bridgestones that cost about $350 each at national tire discount. I get as good or better wear out of the imports for about 1/2 the price. These manufacturers go with the cheapest price to haul their freight. It only makes sense to do the same when it comes to buying products for my truck.

[Bandit102]

Agreed. Bought 4 of the Continental closed shoulder steers (for my spread). Paid a premium for them and was told the "wear like steel on a spread axle". They don't. They suck.

Anyway, had one seperate on me. Had a baseball sized bubble on the outside edge of the tread. It was not an impact bruise either. Tire dealer made it good, then charged me back when Continental (General) denied an adjustment PLUS charged me shipping the tire to the factory and them shipping it back. I will NEVER own another General.

Had similar problems with Goodyear tires. Tread flies off in 1500 miles, well, you ran it underinflated. Which i do NOT!

My step came with Bridgestone R194 255/70-22.5's when I bought it new.They last well got 125,000 miles on the front axle running 95psi and got 100,000 miles on the rear axle running 95psi.Bridgestones come with 12/32nd's of rubber and I did some research and found that the Yokahama in the same size came with 18/32nd's and was about $50 a tire cheaper.I put the Yokahama tires on in Oct. of 07' and have 130,000 miles on them as of this week and when I checked the tread depth I had 12/32nd's across the front axle(which is what the Bridgestones come with new) and have 9/32nd's across the back axle ran with 95psi with no funny wear or cupping yet and have not rotated the tires ( going to do that this week) with a dump valve on the back axle the trailer is a 06' wilson combo step.

I can get:

Kelly KTSA for $277
Michelin XZE for $358
Goodyear G104 for $337

all in Canadian. I think I'll go with the Goodyears.
