tires

replace tires at 40k? hahaha I'm dangerous I drove 9 years 100k miles on one set of tires until the dry rout got too bad.

 

For comfort and fuel economy go with the Ecopia EP422. They are not the best for handling, however, I find them fine for daily driving.

There are not many LRR tire available in your size.

 

I picked up my 2013 C3 on May 15th. I took the stock tires off and installed some alloy rims from my older Civic.
The Michelin Hydro 195/65/15's killed my mileage.
I did some research and found the Kumho KH30 Ecowing in a 185/65/15 for 62 bucks a pop.
My rims are 15X6.5 so I didn't want to just swap out the stock 175's. The Ecowing fit the rims perfectly.
They're a much better tire than the GoodYear junk it came with and it's a nice looking tire with 3 center groves.
It's an all season tire rated at 65K miles. It's very quite, smooth, handles well and has a great ride. I've never used Kumho brand tires before, but these were cheap enough to take a chance. I'm extremely satisfied with them
I only had 1K miles on the car before I replaced the stock wheels and tires, but these are returning the same mileage expectations. I ran a 31 mile trip on local roads in just over an hour with an average speed of 29.25 MPH and managed 77.3 MPG on the first trip I haven't recorded a fil-up with the new tires yet, but I will in the next few days.
I can tell by the MPG readout, it's not an issue with the 185's I can say the same as the reviews I researched before buying the Kumho's. They're a 9 out of 10 for a small LRR tire and at 62 bucks, you can't go wrong. I run them at 42 PSI.

 

Be sure to track temperature differences when comparing tires. If I compared tires in early May with temps in the 70s vs. June with temps in the high 90s I could be tricked into thinking my new tires were more efficient. Conversely, in the same situation above, I could start using the AC more and think my new tires were worse. There are a lot of variables associated with fuel economy. We must track them all before we can say with confidence that a new tire is worse or better than an old one.

 

This was all done at the end of May (within about 10 days after getting the car) and first week of June. I purchased my car on May 15th, so I would say within a 20 day period overall.
Temps around here don't swing much and I don't use my A/C. We have the ocean marine layer to keep things pretty even from day to day.

 

I am very impressed with the new Bridgestone Ecopias installed on my '07 Touring after removing the now completely treadless Touranzas that came with it at 40K miles. About a 5 MPG improvement Highway, but the most remarkable improvement was in the stop and go local miles, easily 10MPG. They were bought at Costco, and the Ecopias are rated for 65K miles.

 

The Nissan Leaf forums lovingly nick-named these tires the Ecrapias...

 

...and why is that? There is no info. I think an improvement of 5-10MPG just by changing the tires is impressive.

 

They mostly have mentioned a lot of punctures due to potholes. They are great for MPGs, but, apparently on the heavier car, don't last as long as a tire with a higher rating.

 

ecopias are awesome

 

Tires are a personal preference item, IMO. It's all based on driving habits and known expectations.

 

I replaced my tires imediately because I like corering on two wheels; use tirerack.com to assist your getting the tires you want - long wearing, generally Michelins, or fast cornering, several choices BFG to Direzzas - based on the information in their site and rom hundreds of thousands of customers. If you choodse performance use lap times in their tests. If you want long wearing use their evaluations and ratrings. Geneally the higher the UTG the loner wearing. Compromise on price whre you need to.
BTW changing from OEM to Hawk HPS has resulted in incresing mpgs from 47.4 to 48.2. Thats statistically over 14 refills since converting compared to abot 80 before. Yes, I don't wait for the tank to be empty; when I get near my station with $3.29 to $3.36 gas I refill. normally stations are $3.39 to $3.45 here. Most times its 110 to 210 miles.
