Excessive tire wear

[tbently]

I have a 4.6 with 7100 miles since Nov. '08 and after inspecting a tire with a nail noted excessive wear in the center. This is a Dunlop stock tire and yes I check the pressure regularly (32-33 psi). I called the dealer who said the Dunlop tire is very "soft" and sticks well to the road but has a short life span. They run around $200 apiece. I will be surprised if I get 12K miles. Going in for rotation and oil tomorrow. If and when the tires need replacement, any suggestions?
PS Dunlop is one of the 2 manufacturers that does not guarantee their tire according to my dealer.

Even for a soft tire you should get into the 20k range. The tires are not ZR rated so I would expect a minuim of 25k plus. We have a Toyota Sienna has well and we had to do tires at 28k, (Bridgestones). I fought for weeks to get some sort of compensation with no luck. I was told that the OEM tires on cars are softer to improve the ride, hence they wear out faster. I have no idea if this is true.

I have 11,500 miles on my tires so far. Rotated them at 8,500 miles. Still plenty of tread on them. One of these days, I will measure the depth left. When I looked up the tire in TireRack.com, it said that they come with 10/32" tread, and the one I am thinking of replacing them with (BFG KDWS) has 9/32" tread.

Note that the KDWS is a different tire than the BFG KDW (also known at the KDW-2).
I had very good luck with the KDWS in a past car.

Yes! The stock tires tread life is horrible...and HORRID if you spin them like me.

I had them rotated at 6K and unfortunately they were inflated about 3 PSI too much and so when I spun the tires...the centers are almost bare.

Stupid me...I should have checked them from the dealer.

Now that my PSI is right...and after burning my rear tires even more than before the rotation, they wear nice and even and I have a TON of tread left.

CHECK YOUR TIRE PRESSURE!

I do not expect these tires to last near 20k and I am at 10,300 as of last night.

Tire wear depends on a number of factors. Type of rubber is just one of them. How you drive and where you drive are major factors too. If you drive mostly in city traffic with lots of stop, go, turn, etc the tires will wear out very fast. Frequent highway driving on smooth freeways will last much longer.

I bought my Genesis last September and I have almost 15K miles on the car. I have absolutely no complaints, including the tires. I have had the oil changed 3 times and along with oil the tires were rotated each time. I think I will get close to 40K miles on these tires, tire inflation is set to 34lbs.

Well, being my first post I do have to say a quick hello to all. Quickly though, down the business.

Being a certified Michelin technician I can assure you that having your tires inflated 3 psi above the manufacturer "recommended" tire pressure will not noticeably affect the wear of your tire. Also, there are a bunch of things that need to be factored in, all of which were mentioned in this thread.

In any case, however, it is to be noted that spinning your tires - any tires, at that - will greatly reduce the life of your tire.

I'm not exactly certain if the car comes stock with Dunlop SP Sport 5000, the tires which were on the car at the NAIAS this year, but these rubbers aren't exactly getting rave reviews. Moreover, they are mixed reviews... a lot of people have complained about the lack of durability, although some are saying its one of the best tires they've bought. Then again, some people are buying these tires for their Civics and Mazda 6s... make of it what you will but either way, OEM tires don't last. If you drive it like you stole it, you won't be getting any more than 20k miles on these tires. Then again, that is to be expected from sport tires.

I have only about 8k miles on these tires and I'd say they'll need to be changed at around 10-12k miles. Not good at all, but to be honest, I can't wait to switch to a set of Michelin Serenity tires so I can report on how much the ride has/has not improved. I have a feeling a large portion of the suspension problem some people have w/ Genesis is tire related.

The specification to use 33 PSI is primarily to achieve fuel mileage goals for the Genesis, including Hyundai corporate CAFE numbers. Personally, I think that is a little high, and I lowered mine to 31 PSI (I have a very accurate digital pressure gauge).

The symptoms of a tire wearing faster in the center than on the shoulder is consistent with the tire being somewhat over-inflated.

Mark,
I wonder at what pressure does the automatic tire pressure indicator light up on the dash board? I'd like to drop my pressure (if it is 33lbs) down to 31lbs also).

My dealer fills all their tires with Nitrogen, and (your not going to believe this), I have never checked the pressures since I bought the car on January 9th. I also have a very accurate digital pressure gauge, just sitting in the glove box. Although I've never checked the pressure, my dealer does check it, whenever I go for an oil change.

Nitrogen fills have the little green caps.

BTW, my tires are still wearing great. Over 12500 miles on them, and they look almost new. Very even wear across the tread. (I did rotate them at 9700 miles, using Hyundai's pattern).

It doesn't come on anywhere near 30 PSI. Last winter on a very cold day the monitor came on for one tire at start up (cold tire pressure drops about 1 PSI for each 10 F drop in temp from 70 F). The monitors are not all that precise either, since only one monitor came on and all my tires had the same pressure.

I corrected the message below. After checking my records, I rotated my tires at 9700 miles, not the 8500 that I previously stated.

When I had my tires Rotated at Dunn Tire, in Greece (Rochester) NY, I noticed that they advise replacing the small rubber washers, and seals in the tire pressure gizmos, in each tire, when replacing tires.

I saw the same information somewhere else, but can't remember where it was.

Dunlop makes a less sporty version that's very similar to this tire, but is softer and better suited to grand touring and incliment weather. It gets very high marks from reviewers.

Were is everyone getting this 31-33 psi tire pressure? The tire has a 51 psi max tire pressure. Please advise on where this states to put the tire pressure at 31-33psi.
The tire I'm talking about is the Dunlop SP Sport 5000, 235/50R18.
These are listed at about $220.00, not a cheap tire. So for those who are changing tires and are getting a better suspension feel, please lists some tires and prices. Thanks

The rating on the tire is just the MAX pressure it can handle. The appropriate pressure for a car is on the inside lower door frame of the drivers side door.

This is the information you want to go by, not the tire.

 

[jwaters943]

Check your door jam (drivers side) for recommended "cold" tire pressures. Anything above 36 and I'd say you're running the risk of uneven tire wear (the tires will wear more in the center), plus it rides like crap. I keep mine around 33-34.

 

[PLO5]

I see clearly now, the pressure from the dealer was set at 39 psi, I just dropped it to 33 psi. Thanks

Jwaters,

I checked Tirerack and don't see any Michelin Serenitys listed for the Genesis in 235/50-18s? I do see the Dunlop SP Sport Signatures that TJPark recommended and they seem to have really high ratings.

I have 10,000 miles on my Genesis and the stock Dunlops have excessive wear and are absolutely horrible in the MN winters. I do not want to invest in a second set of wheels and tires for winter so I am looking for a decent se that will work year-round.

 

[jwaters943]

They're actually Bridgestones (don't know why I thought they were Michelins). They didn't get very strong marks for snow traction though. This is not an issue for me since I run 17" wheels w/ snow tires in the winter. The Dunlop Signatures seem like a better choice if you're going to use them in all 4 seasons, and they're much cheaper too. Good luck. Be sure to let us know what you decide on what effect it has had on ride/handling.
