22” Continental Terrain Contact A/T tires resulted in a negligible INCREASE in efficiency (2.07 mi/kwh) compared to OEM Pirellis (2.04 mi/kwh)

My OEM 22” pirellis were worn by 21k miles.
Got Conitinental terrain contact A/T 275/50R22 through simpletire (and installed at Firestone)

chose these based on nearly the same load capacity as OEM, deeper tread (12/32 vs 7/32) and 60K mileage warranty

was a little worried about impact on efficiency given added weight of the tire (43lbs vs 37 lbs) and more aggressive tread pattern.


I drove the same commute the week before and after changing tires. Over 80 miles of a 50:50 mix of city and highway driving my efficiency was actually better with the Continentals. (2.07 vs 2.04 mi/kWh)
This is obviously negligible, but I expected a moderate decrease in efficiency. The only other variable was weather, was colder (39F) in the Pirelli day and 48F on the Continental day


FWIW cabin noise is only marginally louder, I doubt I’d have noticed the difference unless I was looking for it.

You should see a further improvement as Road Vulcanization occurs. The tires at this point are pretty soft, in about 3-6000 miles, they will harden up further.

You may just given me my new replacement tires. I have about 15k on my 22” stock set I will most likely be replacing come next summer

I’m desperately trying to figure out the bike with two saddles that isn’t a tandem.

That's a Shotgun for kids?

I used a trailer bike with my youngest son and he never pedaled! That monster just sat back there and coasted

Nice tires. I would get these or Michelins when the time comes.

 

[Tucker74]

Those are definitely an upgrade

 

[RWerksman]

Nice!

For those with 20" wheels, they make them in a size that fits that too:

Yea it’s a pretty great way to get kids out on the trail. It’s surprising how aggressively I can ride with them

I’m considering the HTs vs the ATs for my next warm weather tire. I don’t do any off-roading which is why the HTs.

Those tires look great!

OP, you commented on noise but have you noticed any difference in ride quality?

I have 13k miles on the TerrainContact A/Ts now. Right at 2.0 mi/kWh. More than half of my miles are on the highway (road trips), and at least half of those in Conserve (known to cause accelerated wear on fronts). I recently posted an update on efficiency, wear and noise in another thread (at around the 11k mile mark). Great tire, would recommend.
