First long trip with my 86...

[Decep]

Used to never get below 30mpg until i changed the stock tires... MPSS in stock size was a 2mpg hit!

Yes, well almost, 319 miles on 7.875 gallons. It was all highway speeds between 65 and 80, cruise control on, no traffic. I filled the tank before getting on the Interstate, and filled right after getting off the interstate. One stretch no stops.

Here is my breakdown by fill-ups, all calculated. Of those, only 7 were less than 7 gallons used. I hate stopping for gas.

Must've had one heluva tail wind. I'm impressed.


My highway mileage falls right in the middle of your bell curve.

Probably the difference between the AT and the MT in cruise mode. My car spends most of its life averaging between 45 and 50MPH per tank so that is why my overall average falls closer to the highway miles average.

EDIT: pretty religious about my tire psi as well. 36 psi all around

I switched to the Bridgestone Ecopia Ep422 Plus tires when the Primacies needed replacing and haven't regretted it (on my second set). All Season, a little quieter, more grip, and a 70,000 mile warranty with no loss in MPG in fact it may have increased slightly.

I realize they are "grand touring" tires but that's basically what I do in my car 98% of the time anyway.

That's good info. I'm about to mount my third set of Primacys. They came off of @humfrz' car. My second set came with the wheels.

Yeah i don’t mind them either. They are just a bit noisy, but overall, they perform well for our cars. I’ve never had a new set though. These are at like 2/32nd so that might be why they’re noisy lol waiting to get new wheels and I’ll definitely be switching tires as well
