18 wheels on that semi or 10 ?????????????????????????????????

Your going to get 50% that love them and 50% that think the people that love them are stupid. The biggest thing about SS's is rolling resistance, which equates to better fuel mileage. If you thing buying cheap tires is better for you business than you won't want to touch SS's, they aint cheap. Unless, you look into Ring Tread tires.... Just purchased two SS's for the trailer and cost was $600 for the pair. Their will be more on here soon...

 

The main difference is weight. Super singles save you a few hundred pounds over duals. The second reason is fuel mileage. Super singles have less of a footprint on the road resulting in lower rolling resistance. Lower rolling resistance requires less power to move the vehicle and saves fuel.

If you drive over 65 mph or your truck has more than 450 hp don't buy super singles. Driving over 65 will cause the tires to balloon and cause irregular wear. Because of the tire having a smaller footprint than duals, they are easier to loss traction and cause cupping. I hope this helps. I'm sure you'll hear a hundred different answers, but I can only tell you what I know

 

I have never heard about the over 450 hp and over 65 mph thing.... I have 535 hp and drive over 65 all the time and the trailer tires are SS's and they have a wearing on the inside of both tires on the rear axle...

 

The 450hp rule is assuming a driver is hard on the throttle when accelerating. As long as you're easy any hp is fine

 

The best reason to go with wide base single is because they are way cooler looking than duals.
Either duals or singles I try going for the lowest rolling resistance tire for my operation. I currently run singles on my tractor and duals on my trailer. I'll probably switch my trailer over to singles to save more weight. Some operations may not want to risk running singles. If you have a higher risk of getting a flat (like an operation that does some off road driving) then it may be better to stick with duals since a wide base single cost about twice as much as a regular/dual. Aside from peoples differences in preference/emotions on the issue to decide what's best for any particular operation you have to run the numbers and if you change track the numbers to see if you're getting the results you expected.

 

Too much torque on starting up gives you that heel to toe uneven wear you see on lugged SS drive tires. Cupping is caused by loose wheel bearings. Yep, agreed benefits are lower weight, and fuel savings... if and only if you do buy a true low rolling resistance tire. Not all super singles are low rolling resistance! You can certainly buy low rolling resistance duals too... just not as low as you get with the SS tires.

I have never really had any problem with starting traction with SS tires... get stuck in all the same places I did with duals. As you wear them down, you do have to be more careful on curves in bad weather. SS tires will break loose a little sooner than duals will, but it's a smooth break and much easier to control. Just slow down a little more in bad weather in all the places you would expect a little trouble and you're good to go.

 

The one major factor in my opinion is if one goes flat or blows, your screwed. No limping to a safe area with out ruining a tire and wheel and possibly the drum. It happens way too often and never in a good spot. or close to a repair shop.. Just weigh the cost to change from duels to super singles. You will have to drive a little different especially in hard rains as they tend to hydroplane a bit easier than duals as water run off is not the same.

 

If you're adequately maintaining your tires and not running over road debris, you won't have blow-outs. The biggest reason for loosing a tire is underinflation. That's a real easy problem to correct.

IMO, if you're going to buy SS tires, you should probably be looking at a tire inflation monitoring system too.

 

You can only continue to drive with a blown tire if you're an outlaw trucker. Also you can't limp on a blown steer tire. Another possibility is to carry a spare and change it yourself. A tire pressure monitoring system can alert you to some issues before you end up stranded. I don't carry a spare but I do carry some tire patches. I had one tire blow out since 2005 and that was caused by a slow leak at the valve stem gasket that a tire pressure monitor would have alerted me to before well before a blow out. Taking proper care of your tires and a tire pressure monitor will go a long way to preventing any blow outs. Also you could run something like Ultraseal or Tire Lyna in your tires.
