No more super singles?

Real nice way to lump everyone into one heap. Very enlightened and non-judgemental of you. No one has any idea what I do or do not know, what I have read, and what I have tried. I read anything I can find, read results of test, but the best opinions I can find beside using my own test is to read user reviews, and lots of them. The person who stated his whole fleet was a tester for Michelin was the one person on here who has some real working knowledge over a wide variety of conditions. I would very much line to look at his companies numbers to see exactly what the savings may or may not be.

 

So a duel blowing out is more likely to make me swerve than a SS blowing out? I am only asking cause in the end they are both tires. Even if one duel causes the other to blow its no different than loosing one super single am I right? Or is the SS a super tire?

 

I've seen some wicked stuff when duals blow. One blows and takes out the other, parts get wrapped up in the brakes and lock the tire up causing the truck to pull to one side. I've never seen a single blow yet but I'm sure it's dangerous as well.

 

They sure leave a mess in the road when they do blow. There is a post somewhere on here where a TMC blew a single and took out his air bag. I've blown many a dual tire and never taken the other one except once, on a church bus. The tire caught a piece of bracing steel and ran it through the other tire. Both blew less than a second apart.

 

your right, and if they run less profitable it helps to keep my rates higher...so yea, don't Liston to me and run whatever you want lol. I'll be able to undercut you on price or make more profit.

 

Any blow out is dangerous, dual or single. Single seem less likely to blow out, but if they do damage is probably similar. In my one single blowout on the trailer, there was no damage.

 

This topic left debate to just plain stupidity a long time ago. If we can't debate honest opinions and pros and cons of each type tire, this thread is going to be shut down.

I think everything is clear. You spent a lot of money for new tires and wheels and are happy. Others have kept the tires and wheels they have and are happy. You won't change their mind, and no one is going to change yours. You went from mis-matched recaps to new low RR singles, you can't help but see a decent increase in mileage. You would have seen a change going to new low RR duals also. Would it have been as much, maybe not. Is the difference between new low RR duals compared to new low RR singles enought to offset the difference in cost, who knows, you didn't go from apples to apples. You went from oranges to apples.


I think everyone that is debating you is wanting to see more evidence before spending a lot of money to change. If you have a truck made for duals the track will be narrower with big singles, making it easier to tip than before. New trucks and trailers made for wide singles have wider axles to overcome this problem. Maybe that is why some people report their singles feeling squrimy and others don't.

I did notice a new Watkins Shepard truck and trailer today with duals, and I know they had several with singles a while back. I wonder if they are going back to duals after trying singles. I would like to hear from someone in the know from there and find out.

 

That is something that I should have known but hadn't thought about is the narrower tracking on trucks not designed for singles. Information such as that is what keeps us from making an expensive mistake, or make an informed profitable decision. I have always been a buy a truck rigged like you want kinda guy cause its the minor details like this that get you in trouble when changing things. For some it may not be a big deal. For a man that makes most of his living hauling live cattle and can't afford to be any less stable than he is its priceless. Thanks Stranger for the info.

 

The little amount of difference between duals and SS are maybe an inch or two. No way is that gonna cause a truck to roll over. Crappy drivers roll trucks. Our entire fleet was designed for duals but have since been converted and we don't have roll overs. And we're hauling smooth bore tankers so if anyone was gonna roll due to tires it would be a tanker.

 

if your concerned about roll over, you can get off set rims to keep full width. most companies prefer the trailer being set in 2 inchs because they are less likly to rub the tire on turns with bad drivers. If you tip over your truck though and its not do to mechanical failure, your an idiot. If you get so close that the 2 inch offset makes a difference, then your still an idiot. You should never push your truck that close to its limit. I've never rolled a truck, but I'v never felt any less stable with the lost few inchs.

The rolling resistance numbers don't lie. Find the best dual drive tire and then compare to singles. You will see the RR is lower on the single.

Yes i compared apples ot oranges. What do you expect, me to buy a whole new set of duel just to have an accurate comparison when i swish to singles? Point is i'v run my singles 60k and they show very little wear. Based on RR comparisons, I would expect you to gain .3 mpg or so over best duels. As mentioned do to rebates the conversion cost is about the same as buying a new set of duels, its free to get the extra few %. As for ANY handling ishues you may or may not find. You would have the same problems on a low rr dual. A non grippy tread in dual or single isnt gonna be great. That being said, I've never gotten stuck and i dont even have locking difs. When I drove a company truck, the duals did better in mud, but thats comparing low rr singles to a chunky tread off road spec dual. Again, apples and oranges. Of course the chunky off road tread will do better, but not for mpg.
