Anyone have a recommendation for replacement tires that won't decrease
the current gas mileage I am getting with the factory Dunlop SP31 tires?

I recommend Michelin Pilot Exalto A/S tires. I have seen my gas mileage increase with these tires, and they have a 45,000 mile tread life warranty from Michelin. They are very quiet smooth tires that have much better handling characteristics than the Dunlops.

They are very highly rated by those that have them installed as seen in this Tire Rack survey. They are about $95 a tire.

Ouch.

Here's a really nice detailed chart on tire rack.

The Michelin Hydroedge look like a good bet to me. I haven't been impressed with the Dunlops. Mine have 20k on them and are already looking worn out.

For half the price, the cheapest tire they have in this size is actually rated pretty high. Has anyone tried these?

Try a BMW runflat for some real pain...

Be careful about swapping for just a highly-rated tire. Most-times, tires are rated highly because of traction, handling and/or longevity. I'd take the first 2 over the third - any day.
But notez2id wants to keep his MPG essentially the same. Most reviewers have no idea what impact a tire might have on MPG, so it's not likely in the mix of what they think about the tire.
Orient Express states the Michelin Pilot Exalto A/S did just that for him (and has said so before on this forum). A bonus is that they handle well. even OK in some snow according to the reviewers. I will certainly consider these when the time comes.
BTW, my factory Dunlops are still OK at 37K+ miles.

STOP terrorism - Drive a HYBRID

Vehicles:
350 miles a week ------------ 2006 HCH II, Magnetic Pearl, w/NAVI (born on May 25, 2006)
350 miles a month ---------- 2003 Mazda Tribute ES-V6
350 miles a year (for now) - 1986 Mercedes 560SL

I wonder about this tire. Often tires touted for performance and sport cars are quite a bit softer than LRR tires. Low cost high performance may simply be that they are using a very soft compound to increase traction, rather than high quality design features. Most of the reviews mention excessive treadwear and high noise level, both which point to ultra soft compound. I'd be very wary about putting these on a hybrid. Very likely your MPG would tank badly.

Gonna give the Michelin Pilot Exalto a shot.
My Dunlops got me only 26k miles because of the
defective rear control arms Honda put on the 07 hybrids.
After I got the new control arms a few days ago, believe it
or not, I got an increase of 5-7mpg with the beat up Dunlops.
Will update in a week after I get the Michelins.
Thanks for all the input on this thread.
