Daaaaang. I’m trying hard not to covet my neighbor’s possession...

pretty cool tech for 1965. I actually haven't ran the powered top in probably 5 years.
ill do some maintenance before i flip the switch

Stellar day I am sure.

Grandpa was an engineer, highly meticulous.
I have a notebook with every repair, maintenance, oil change. Anytime someone touched the car it is filed and dated.
Also have original owners manual. And every registration back to 65. Even a list of other owners of 65 gto’s in indiana he had met through a gun club incase he needed original production parts. Grandpa knew what he was doing.

It's not the size that matters if the worm isn't fishing or something like that!

On a somewhat serious note, what is the advantage of the wide single tire vs the dual old school tires? Cool factor notwithstanding, I'm sure there is something that actually validates the choice.

Mainly it's weight. I think it's 200 lbs an axle lighter with the singles than the duals. Easier to check tire pressure too.

I figured it was money related and indirectly I was right. Thanks for the clarification.

Old school Ford Barra engine??

 

[ChristianPatriot]

Basically yes

 

[femurphy77]

That's an old school 200 I6 I believe. Pretty common workhorse for various applications. Another pretty common workhorse at least some years ago was old Chrysler hemi's. I'm talking about the old 392 and earlier variants I believe not the popular 426. Quite a few of them spread out at various oil field locations in TX, OK and KS.

I pulled to main building HVAC pumps out t5hat had the old 340-ish CI Hemi's driving the pumps. The throttles were Pneumatically controlled. The systems were from Chrysler and the pumps were actually Chrysler radials which were fairly common in the late 50's early 60's.

Systems were just worn out. But I could get the Hemis started.

Actually the super singles at almost exactly double what a dual tire costs. Go figure.

I was talking more about additional payload but that probably doesn't have a big impact. It's probably more cumulative; less wear on drivetrain components, lower fuel use, additional payload, ride improvement, etc. Probably all negligible but you know what I mean.

Lower rolling resistance mostly, especially if you're to believe all of the claims Michelin made when they originally released the X One. They were doing all sorts of elaborate stuff with compounds back then (and probably still are) to increase economy, plus the smaller overall contact patch (they actually had to go to court over that in several states to get them legalized as states were claiming they were harder on the roads via more lb/in^2 on the roadways) is just lower resistance to begin with. The weight capacity between a super single and a set of duals is generally the same, so no advantage there. That probably varies widely depending on which single and which duals we're talking about.

FWIW, Michelin's marketing guys were pushing the point that the cost of the new wheels required for them would pay back in under the life of the original tread in fuel savings alone and by the time the carcass was worn out (I think Michelin allows 3 retreads on a carcass if they're they ones doing them... can't remember anymore for sure) the entire cost of the wheels, tires, and retreads would be free, in fuel savings, as compared to running duals if you had them on your entire setup (truck + trailer) plus whatever whiz-bang low rolling resistance steer tires they were also marketing at the time. I think they even drummed up a partnership with Alcoa based around that logic.

All of that I got straight from the horse's mouth, and clearly they'd be the most proud of those suggested accomplishments, so real world results probably vary. I do see more and more of them out there though, so there must be some truth to it.

This guy must have really had to poop.

Also, that thing pulls hard AF up to 180-ish.... Wow.

Rolling resistance is a big thing. Using Michelins number system, every 10 points lower is a 10th of a MPG. So take the "Double Coin" tires with a rolling resistance of 160. (My numbers for example only but probably pretty close). Your long nose Pete is getting 5 mpg and you're doing 120,000 miles a year. That's 24,000 gallons of fuel. And let's say $3.00 per gallon. $72k in fuel.

Throw on a set of X Line with a rolling resistance of 100. 70 less the the Double Coin. That's 7 tenth a mpg. So now your mileage is 5.7. Now you're only using 21,052 gallons of fuel. That's 2,948 gallons less. That's $8,800 a year. Tires will go at least 2 years. That's $17k in savings.

So your $250 per cheap tire vs. the $500 for the Michelin. The $2,500 savings actually cost you $14,500.

I always wanted a set of Super Singles on my truck. Probably do a 4 or 6 inch lift, super singles front and rear. I think it'd be BA. I won't ever do that with this truck; maybe one in the future?

I got the driver side control arm on last night. Passenger side has to come off tonight. It's a rear lower control arm. I'm 99% positive that both bolts are seized up inside of the metal sleeves in the bushings. Going to have to get rough with it.
Suggestions? Sawzall hasn't worked out too well in the past and it's too tight of space to get a cutting wheel up in there.

 

[femurphy77]

Yeah when I was still working for Goodyear they were working on a high silicone content tire that greatly reduced rolling resistance. One of the hurdles that had to overcome at the time though was static discharge. Seems the high silicone content did a much greater job at insulating the vehicle than standard rubber based treads, as a result you'd get a pretty heavy zap when you'd grab a door handle or other metallic part of the vehicle.

Big ass breaker bars and 6 point sockets? Soak it a couple days with some good penetrating oil and then put the kung fu grip on it. That or use the blue tip.

I am not a fan of convertibles for my own personal reasons so let that be a point of reference. No knock as that is an amazing car in its own rite.
65's are just the absolute coolest of the Goat line up IMHPO.
