I switched to Prielli's, not racing tires, but the name sounds like they are! They handle really well, a big improvement over the OEM's. I increase the air pressure to 42/40. I still seem to get the same mileage.

In winter I use Dunlop Graspic winter tires. What a BIG improvement in snow! Also raise the air pressure. There is about a 3-5 mpg decrease, but the handling improvement is worth it.

Default Goodyear Comfortred versus Michelin Hydroedge Tires

Whoops! I posted this as a new topic and probably should have been here. My 04 needs a new set of tires, only 37,000 on the Integrities but the dealer told me they would not pass inspection which is coming up in Feb.
I like the Michelin Hydroedge and know a couple of you have had good experiences with them. Problem is I look at other web sites and they are slammed quite a bit for road noise. The Comfortred scores much higher in this area and very close to the Hydroedge in other areas, of course they are rated for 80k not 90k of tred life but most people that have them seem to make a point of saying how quiet they are and how they smooth the road out. Here in Western NC we have very poor roads, the interstates are in poor shape. So..... looking for advice from those of you that have the Comfortred or the Hydroedge.
I realize that tire inflation plays a large part (run the OEM at 42/40). and of course while not a deciding factor, the Michelins are about $108.00 more expensive for a set of 4.

Default Michelin HydroEdge Tires

Costco and many other tire dealers are offering $60 off a set of 4 Michelins. This offer has been available off and on for the past couple of years. Now, they are only about $50 more.

I'd get the Michelins -- you get what you pay for...

Default Mileage with Assurance Comfortred

When we replaced our Integrities (39/37) at 42K miles with Assurance Comfortred (39/37), we lost about 3MPG. But after about 3K miles the mileage improved 5-6MPG. With lower tire pressure, mileage drops. For the summer of 2008 (when we needed it) we averaged over 50MPG, which made us happy. Overall mileage for 47K miles is 44.96MPG. Update 04/2010: Overall mileage for 60K miles is 45.0.

Default New Tires and Gas Mileage

Bigger Tires or lowered will help a ton. Still doesnt look that bad though. I bet it feels faster like you threw lower gears in the axle. Has the gas mileage changed much?

Check tire rack - they can tell you different weights of tires - you'd be surprised at the differences - and which are low rolling resistance tires. I hear good things about the Michelins.

Our Goodyear Assurance Comfortreads are still going strong and mileage is gradually improving as we approach 70K miles. I run 38-40F, 36-38R. There is little apparent wear. 48mpg is not unusual with lifetime average of 45+mpg.

Bridgestone now sells a LRR tire, the ECOPIA.
