Has anyone tried replacing dual drive tires with super singles?

[sfedeli3]

Sam,

I've been running Michelin 31580R22.5's in ALL positions for a year-
22K miles so far- they were a great replacement for the 12R22.5's and
fit the same rim. I started with the steers in Jan. 2008 and liked the
ride so much that as $$ permitted, I got them for the drives in June
2008 and tags in December 2008. They are a load range L tire. Make
sure the duals are at 110 PSI and they do not touch each other. They
also do not rub the fenders. You will be amazed at the ride difference.

I wouldn't rule out using quality tires from another brand. Toyo and Sumitomo seem to have a good reputation. Personally, I'm leery of the Chinese tires...

12R22.5s are not as common as the 11R22.5 -- but most larger truck tire stores and chains seem to be able to get them (but you're less likely to get a "super" sale price -- however, those "super" sale prices may be on tires that are actually stale and have been laying around for 5 or more years... )

I thought of doing that myself just for the look but I was advised that wheel replacment was needed and they are EXPENSIVE!

I have excellent tread but the dreaded sidewall cracks from sun and
age. Looking for the best retire options for my 1985 PT40. Just
wondering if anyone has tried super singles on the drive axle? Thanks

I looked into super singles for my drives before I retired in
Washington state.
Found that they could hold 13k each, but the rims, being special, cost
600 bucks. Tires were also 600 bucks. Weight saved was 400 lbs.
Wasn't worth it so didn't.

I have 22.5 on the steerand 24.5 on drive and tag. Would anyone want to swap the 24.5 for my 22.5? Don't know why the discrepency. Sure is hard to change a tire if I have a blowout on the steers.

Bob,

My 315's are $600 a piece. If I could find a super single that could
handle the weight, I'd be happy to buy a wheel for $600.00.

Let's see:

If I stay with four 315's:
Four new tires is $600 times four: $2400

Or I could spend extra initially for the new super single wheels:
Two wheels at $600 for a total of $1200, plus two tires at $600
each for a total of $1200 and a grand total of $2400.

Future tire replacement saves $1200 with the super singles!

I'm sold, where did you find the 13000lb load rated super singles?

I looked into these at Les Schwab Tires in Lakewood, Washington.

The other problem the mgr stated that if I blew one of these out in the
toolies town, that the local tire shop definitely wouldn't have them.

Bob,

I wonder where all the H.E.B. tractors and trailers that are on the highways in Texas get their serviceif they have a problem. They seem to have changed out all their equipment to the super singles And with 300 plus large grocery stores to service I am sure they took this into consideration. I also read that the EPA is encouraging this change over for fuel efficiency Probably wouldn't affect a motor home much, but here must be some good reason to invest in this change over.

Hi,
Safety should considered before a little fuel and a small percentage $
saving.
On the commercial rigs that use these, the economics play a bigger
role. Safety is less of an issue as these rigs are not overweight and
enforced maximums of 20,000 lbs per axle. Also a professional driver
is checking tire pressure daily, unlike most or all RV owners.
If a super single had rapid failure in the drive position, the
results would more likely be serious compared to a pro driver in a rig
that would not be damaged by disintegrating tire.
The dual gives a large safety margin.
Also the max load is 22,000 per axle at maximum pressure. With side to
side variance in RV's ,the pressure would nead to be max. No safety
margin.
Definitely a poor choice IMO.

Ross,

After you watch the videos on a truck and fully loaded trailer and on a bus with actual blowouts on the Michelin website I am impressed. Apparently the safety issue is a non issue. Cost to convert and fuel savings are the real issue for an RV owner.
