LRR tires

Recommended Posts

Recently got new tires for our Prius and I went with LRR (low rolling resistance) tires to see what difference they made. It was pretty significant; I'm now getting 56mpg on the 130 mile round trip to the DZ averaging 70ish on the highway, and I got 62mpg when driving specifically for efficiency (averaging about 65mph on the highway.) Previously I got 46mpg or so on that round trip.

The tires (Bridgestone Ecopias) were about $30 per tire more than the last set I got. So they'll pay for themselves in about 8000 miles.

No noticeable changes in handling. I haven't taken it to a skidpad yet.



I would be interested to know what the drag factor is when compared to a typical passenger car tire on the same surface. My guess would be if a surface is around a .75 for a standard tire then the LRR would probably be around a .65-.7.

I had some Michelins on my Honda that got great gas mileage, but the wet traction was lousy. Got a set of Bridgestones that have much better wet traction, but about 10% less gas mileage. Worth it in my opinion.
I'd be interested to hear how the LRR tires do on a wet road.

He, uh, did say it was a Prius. ;)

OK, that might sound like a cheap shot and while on one level it is, my guess is it stops reasonably close to the same as stock since the stock Prius tires are pretty low rolling resistance to begin with compared to most normal street tires.

Priuses (Prii?) aren't exactly known for their stellar handling. I'd be curious about its ability to go around a corner and whether the amount of braking required before the corner nullifies the energy gains made in the straights.

I don't know about LRR and all that stuff but I can vouch for the change in mileage on different tires.

I had 100,000 mile tires and got 26mpg.
I had new tires put on just before a long trip and I bought 30,000 mile tires (yes, I'm a cheap bastard).

I got 21mpg with the new ones. I thought that was not right. I checked air pressure and found that the tire guys didn't properly inflate them at installation. I pumped them up to proper pressure and now I get 23-24.
So...
100K = 26.
30K = 23-24

Sucks to be me.

Oh...to reply to others, too....
The 100Ks, being hard, the traction was iffy in wet conditions and I had to be careful on how I drove in the rain.
The 30Ks, being softer, I get more stick-to-the-road. Now I can drive like a wild man again!
:D:D


Ummmm...come to think of it....maybe that's why the mileage dropped.

John...the pic was from SansSuit. You should have known what you were getting into before you opened the pic.

:)


A Prius will fit in your pocket.

Don't you mean "die Gürtelreifen" for our "fatherlanders?"
