I have a 2009 C6 with 24,500 miles. Interestingly, I am noticing the tread almost flat on the passenger side front tire and nearly flat on the driver side. Tread is wearing out in the middle of the tire. Is that normal to have front tires wearing out with only 25,000 miles on them? Rear tires are fine. Also, is this correct specs (245/40-18) for front tires?

Recommendations, on replacing front tires only with original brand vs replacing them all with a new brand. The rear tires do not need to be replaced, but I'm a little concerned about mixing brands with front tires and original brand rear tires. May make more sense to just replace the two from tires with the original brand. What do you say????

Do you have the OEM Goodyear's on the car? If so they usually do not wear much better.
Over inflation would be the cause of the middle wearing out first.
BTW, that tire size is correct.
Everyone has their personal choice of tire, and I'm very happy with the Firestones Firehawk's Wide Oval RFT.

From your description, it sounds as though your front tires have been over-inflated. It is my understanding that people seldom get over 30,000 miles out of a set of tires on a 'Vette, but I may be incorrect on this mileage.

As for mixing brands of tires, I'd say to allay any of your concerns to just replace the fronts with the original brand. Hope this information helps.

Thank you for the input. We have a Firestone nearby, will they have the Goodyear? I'm assuming they have the pucks for the lift....

Your tires were likely over inflated and without the edges being worn down, it likely wasn't thrown into too many curves at high speeds.

25-30K miles it about standard, if even a little more than most Corvettes tend to get on average driving. That's not out of the ordinary.

The general concencous is to go with non-run flat tires for the best ride and performance. However, if you plan to freqently travel long distances to the middle of nowhere frequently, the saftety of run-flats might be more for you.

Hankooks seem to be extremely popular in the NRF tires and although they fetch a pretty penny, the Michelin RFs tend to be the most popular if you want to go with another RF.

Hard core trackers will tell you to never ever mix brands on the same car, but there isn't really a whole lot of danger if you don't plan to do anything that pushes the envelope.

Funny how some dealers would and not, I guess depending if they are privately own and operated.
I had to change all the Goodyear's out early as they just seem way to noisy, wore terrible, but when I did a great improvement.

Never mind, Firestone doesn't have Goodyear. Found a place that total out the door price for two tires, $700.00.

Just curious about tire pressure. We get extreme fluctuations in temperature in Houston from Dec through Feb. A front will blow through and it will be 28 degrees. Two days later, it's 80 again. Have a hard time keeping pressure in for both extremes. What would you recommend trying to keep tire pressure at when you first crank the car in the mornings? (Garage kept)

30 psi.

You live in a variable climate but for me in the northeast, I have a summer and a winter pressure that I'll use. Summer a little lower than the 30#'s called for, 28#'s, and bump it up in the winter, 32#'s as I drive mine through out the year also.

RocketDawg

What I would do would be to set the cold tire pressure at 30 on what you would consider an average day, and then don't worry about the variations (actually, that is what I do). Pretty much all locations get extreme variations like that. Reset the pressures every 3 or 4 months. It's not THAT critical to have them right on 30.

Race11

When the pressure goes to 28 psi and that damn light comes on. Back tires same pressure?

extrapilot

Purchase yourself a tread depth gauge and check the tread wear down the road some for consistent depth across the width of the tire and adjust accordingly.
Here's a nice one

Your light comes on at 28 psi?
Mine doesn't come on even lower than that, but maybe the computer allows for this given the outside temps are lower in the winter here, not sure.

Race11

Yep, it drives me nuts. If I have too little tire pressure and the cold front comes through, it drops to 28 psi or lower. Add a little...and in a couple of days....38 to 40 psi. I'll try setting it at 30 on a cold day and see where that gets me. Thanks for all the input.

I would not assume they would have pucks. I wouldn't even assume they know what pucks are used for. Pucks are a cheap investment and easy to store in your rear storage cubbies.

RadarP3C

I believe the light and message should come on at 24 psi or less.

RadarP3C

When you set the cold pressure at 30 psi, ... expect the pressure to rise to 32-34 psi when the tires warm up from being driven. This is normal.

Sunnyvale Dave

In California, any time you have your car serviced, they have to check the tire pressure. Some places will set the pressure higher than 30 if it is a warm day or if you just drove the car to get there. Otherwise, I am down around 27-28 at the start of the day.

RadarP3C

Are you actually allowed to check your own tire pressure in California? I thought it was only lawful for state licensed and regulated shops to check, add, or decrease the pressure in your tires. And if over-inflated, the released air from the tire had to be brought to a local EPA containment center.
