Super Single Tires

Compared to my tractor running Bridgestone M720's, just changed them out with around 430,000 miles on them and 4/32's left on tread. Not quite as heavy as you are running but average a little over 35k lb in the box, year round mpg average counting all miles, idle time, no APU.. In the mid 7's. But then, the M720's have a low rolling resistance out of the starting gate that gets lower and lower as the tire wears. So there are dual tires that can compete very favorably with SS.

Just got them retreaded with low rolling resistance Michelin XDA2 23 AT treads for $170 a tire. First week on them... ECM showed 8.4 last week and 8.3 mpg this week. But the ECM is about .5 mpg off compared to pump to pump calculation. Really right around 7.8 calculated. Not too bad for new tread.

So.... No real incentive for me to switch to SS.

 

Wrong! We use supersingles here in Europe since early 80's, all trailers have them, we generly only have one drive axle but the rest are singles, running duels ruins fuel economy( and no puncture will cost you more than u save in a year) the tyres stay cooler and tyre scrub when turning is significantly reduced , also a supersingle is cheaper to replace the two duels

 

As far as flats go I've yet to see a Mesilla Valley company truck stopped with a flat and they are almost 100% singles on their fleet.

 

3 days ago I just had a SS blow out at 65mph with 41,000 in the trunk and had no loss of control nor did the rim touch the ground...I also had to stay on the road as it was in a construction area with no shoulder, I probably drove 1/2 mile with it in shreds...I sent picture of it to a friend who I'm hoping can upload it...He may have deleted it though...

This was my 3rd SS blow out and I've yet to lose a rim or have any control issues...
It's sideways, but you can see how destroyed it was...That is without anyone touching it...

 

That looks like a re-cap tyre, you can tell by the way the outerband has separated , here it's illegal to put them on a tractor for exactly this reason, re-caps are fine on a trailer but always put new tyres on your tractor, instant blow outs like that would never happen

 

here we mainly put retreads on drive axles where we have twin new tires on front axles and mainly new on trailer axles i think here super singles on drive axle will never become standard some trailers use super singles for 40or more years

tires are too expensive there is still no retreads this require tpm and esp which cost more than 3000€ +~500€ more for super single

also those tires are sensitive on bad roads

 

Im looking at buying some new tire for my singles i run michelin XOne XDA Energys now but bridgestone is also making them now does anyone know what the bridgestone rolling resistance for wide base super singles are?
What are the michelins rolling resistance now i was told they have got better sence i got mine?

 

I don't have a solid factor for the RR of the BS GTEC because I have a single RR figure for steers, drives, and trailer combined. I can tell you that the RR of the Michelin XDA Energy 1 is roughly 17.5% lower than the RR of the Bridgestone GTEC. (all else equal)

 

michelin-xone xda energy -86 rr,michelin-xdn2-120rr,goodyear-g392 ssd-116rr,

 

All 3 blow outs were replaced with NEW ones, no recaps...They replaced the 4th one when the 3rd went so I had 4 new tires...I love my SSs!!!
