New tires, bad MPG

[JAFO]

I been researcing for new tires and I just read an article in Consumer Reports at Lunch that said that heavier lug tires (mud/snow) have higher rolling resistance.

5 gallons / 50 miles = 10 MPG

Wow, mine gets 18-20mpg on stock R18 Duelers. Big change.

Spend any time on a bicycle .... especially on the road ....
.
and you will quickly see the difference tires can make ...... weight, width, tread pattern ......
.
There is a good reason 'Triathlete' .... Billy .... is riding those skinny tires !

Bias tires like the Thornbirds will get lower MPGs than radials as well - higher rolling resistance, more rubber on the road in this case and more weight and sligthly taller height.

Your speedo and odo are off by3% - 60 on speedo is really 62mph. Your mileage is slightly better in town than 10MPG and of course will always be lower than highway.

I also forgot tire pressure. Your not running them at 5psi with bead lockers are you? :bgwg:
