Hi,
I have joined the forums for a couple months now mainly just lurking around. I have a 2007 G35 Sedan with the 18 inch stock upgrade. I am around 20K and I am in need of new tires. I have spent the majority of my sunday afternoon/evening reading through the forums looking for suggestions. Basically, I couldn't find the answer I was looking for. What is the longest lasting tire for a person that uses the G for a daily driver? (20K+) I am not looking for high performance as i barely ever go past 85. But low road noise is a must. Please help.

u can buy my tires im not sure if they'll fit your stockers but if you buy some new 18" rims they will =D They are toyo t1rs

 

you can go for the harder compound tires, usually those will last you past the 20k range. check the tirerack, as they have a system where you can check what you want and it will show the tires available based on your criteria. Avon tech comes to mind, cheap price, high thread wear rating. others will pop up in your search.

 

Just remember wet braking and long life are opposite ends of spectrum.

Wet braking from just 50 mph can vary by 30 feet and 80 mph can be up to 60 feet depending on tire hardness and brand.

Directional tires all get noiser after half worn, as the use the tread depth [as a tuned slot] in noise cancellation.

 

I've read somewhere that the harder compounds used in higher treadlife tires adds to the road noise (not sure if true).

Check www.tirerack.com for a good resource with reviews. I got my last set of General Tire UHP there.

 

you might want to look into low-rolling-resistance tires, most have high mileage ratings and are "proven" to increase MPG as well.

otherwise look at tire sites for your specific size and then pick out the tire with the highest treadwear rating, just make sure you compare it against others.

 

Consider the following All Season Grand Touring tires (each of which I have driven, though on different vehicles):

Goodyear Eagle ResponsEdge tires, which in 20,000 miles of use, run silent on my G35 coupe and have exhibited only 10% wear from original tread depth. Provide decent ride compliance. Supplied with 50K mile tread life warranty. Extrapolating based on this experience tire should last well past 60K miles before wearing to 6/32 inch of tread depth. The Eagle ResponsEdge have a 440 UTQG tread wear rating (compared to 280 for the OEM Goodyear RS-A).

Even better for ride compliance and wear is the Goodyear Assurance Triple Tred (driven on 2003 BMW 5 series). Comes with an 80K mile tread life warranty and has a tread wear rating of 740!!!! Or the Michelin Primacy MXV4 (driven on a 2005 Volvo S40) which offers a 60K miles tread life warranty and a 620 UTQG tread wear rating. Either of these tires give up a tad in handling to the Eagle ResponsEdge, but offer more ride compliance.

If you purchase a set of four Goodyears using a Goodyear issued credit card, offered at Just Tires, you qualify for a $80 rebate card.

 

Trying to find a high Tread Wear (UTQG) tire depends on mostly on size and profile of the tire. In my application I was lucky to find a tire rated greater then 300. This is typical with 40 profile tire or lower. I just bought Sumimoto HTR Z III (300) and I'm very happy with them. I was also considering Kumho SPT (320). You will find most tire dealers will not millage rate performance tires. You have to do a lot of review reading since UTQG ratings are not always truthful.
On a family sedan you can easily find a tire rated over 600.

 

I just picked up a set of 245/40/19 Kumho Ecsta LX Platinums, with have a treadwear rating of 600. I picked them because of the high treadwear rating and emphasis on low noise and ride comfort (not a performance driver). I'm 18 so I can't afford buying 19" tires all the time.

 

Yes it is true I saw Kumho Ecsta LX Platinums rated at 600 UTQG. Although I only saw one size for 19" rims 245/40/19. I don't believe they make the 225/40/19 in the same style.You will have to get the fronts in the Kumho SPT line (UTQG 320)

 

You cannot use the treadware index to compare between manufacturers as each company sets this number off of their own base tires. Worse this index is extrapolated from a < 8,000 mile test and the end result is a guess at best.

If extreme long life [more than 2 years] is desired I would always chose Michelin since they use stronger materials compared to any other brand and the chances of failure are lower [higher durability].
