They sometimes have to pick the extra wheels up when they go around turns, but I’m not sure why they wouldn’t use them when they need too.  It should make their tires last longer by spreading out the wear.

I used to see these a couple of times a month in Michigan in the early 2000's.  Now I cant remember the last time I saw one.

True, but they also do a great job of blazing a trail if the plows haven’t made it out yet. I went to school in Flint so I was on i75 and US23 a bunch before leaving MI for the Twin Cities where the semis are smaller, the sun shines more, auto insurance is reasonable, and there’s 17 Fortune 500 companies.

It’s amazing to me there’s enough intrastate commerce that those massive trucks are justified.

Michigan takes it to a whole ‘nother level with their Live Bottom asphalt haulers and tankers. Sometimes on exit ramps they will pick up their axles to make a turn and will stop at the light and if you’re next to them the drop axle wheels are still spinning in the air.

Mega Maid!

Gimme a Surly Big Fat Dummy, and the fam is rolling out!

When they leak out, they go down the drain.  That’s why they call it you drained your battery when you leave your light on.

I really want eBay to change transmission type to “3 pedals” so my search functions work properly.

I can’t tell if you’re trolling or not. 3% probably isn’t enough to see in such a picture.

That sounds reasonable. I was talking about how Taema increased tire width without decreasing the aspect ratio, so the tires are now taller.

20cm = 7.9inches.

A 215 is about 8.5”, I can’t see how that would make the tires overall height shorter. Like I had in the link above, when you go wider you should switch to a lower aspect ratio to keep the same overall tire diameter to not change the effective gearing or rub the tire against the car body.  A 215/45r15 is the same…

I’ve been to a bar in Quebec City where they were known for opening champagne with swords.

The 215/50 is taller than the stock tire and could rub or mess up your geometry.

Like I say, I like my sidewalls like I like my retirement communities, 55 and up.

You’re not wrong, all else being equal, but racing tires can have super stiff sidewalls to compensate for taller sidewalls. The tire is heavier, but F1, WRC, Indy, and NASCAR all have (rule mandated) relatively tall sidewalls and it’s not uncommon for race cars to use smaller wheels than the street car. 

I saw that too, Kinda fun identifier for the HDs. Ever since the raptor came out with the amber ID bar lights in the grille I’ve seen f150’s, 4Runners, and even Chevys with aftermarket grilles coping the look.

If you live in a rural area with cheap houses, this “toy trap” can happen fast.

I’ll take a 1500hd quadrasteer, Bob.
