Honda hx rims

[Donut]

why is it that these new rims kill your MPG?

They seem pretty slim themselves...

I'm surprised acceleration is worse. I'd think the HX wheels are lighter and thus less mass to accelerate.

Ok update. The acceleration is affected but slightly and im assuming the wider tires is the cause. Good news, I guess I had to break in these tires. Im getting good mpgs again. By myself driving around 70 mph or so around 45-48 mpgs

My 175/65/15 needed to be broken in too. I was at 33-35, now I get much higher.

We sell those RPX900s at Sears, definitely not the best. XD Terrible cold weather traction. I once installed a set of Verenti R6s (similar tires by the same manufacturer) onto a Miata during a snowstorm. Pulling it around the shop was interesting, I was holding a constant drift angle from just barely tapping the gas with packed snow on the ground.

Tires do have a break-in period, though. The steel and nylon belts need to settle into place and the release lubricants need to be worked out of the rubber.
