Go to tirerack.com and select tires for your car. Look at the UTOG rating for treadwear...anything over 400 is longer lasting. Performance tires are usually under 400.
Good luck.

2007 G35 sport Kumho

Like many on here I have a limited choice for tire selection with the 07 G35 sedan sport package. The tire sizes are front 225/50-18 & rear 245/45-18. After looking on tirerack for available tires there are basicaly three choices. The OEM Bridgestones Ponteza. Performance was good, but I'm not to happy with the tread life. The next is the Goodyear Eagle F1 all weather, which from reading some posts, seem to be a good alternaitve to the Bridgestones. The last choice is the Kumho Ecsta LX Platinum. There are some reiviews on tirerack but none on a G35. As this is an all weather grand touring tire with a rating of 600 AA A. I'm assuming that you would give up some performance for tread life. Anyone have any experience with this(Kumho) or some more feedback on the Goodyear??
Thanks in advance.

I put on the Goodyears and have about 6k miles on them. I was very unhappy with the treadwear on the Potenzas and did not want to put them on again. The ride on the Goodyears is smooth. The one noticable difference is that the tires are a bit harder than the Potenzas. Road noise is up ever so slightly and the stiffness is somewhat elevated. With that said, I am happy with the tires. Grip is fine, ride is smooth and wet tractions is solid, which is important in Florida. They are not as quiet or "cushiony" as the Potenzas, but the sacrifice in those areas is relatively small and, in my mind, outweighed by the treadlife (should it live up to its promise). I'm only 6,000 miles in, so things can change, but I do not regret the change to the F1's at this juncture.

Thanks for your input. It's good to know that the F1's are a good tire. The F1 is probably the way I'll end up going unless I get some feedback on the Kumhos.

I also have an 07 G35 with 18" wheels. I will be putting on a set of Kumho LX today and will report back how they do.

Great. I'm really interested in what you think of them.
Thanks,

Got the Kumho on and drove the car 3 miles back to work. So far so good. The tire noise are all but gone. Much better than the worn out OEM. It's so much quieter and ride so much better than the OEMs. Cornering may not be as sharp as the OEMs but it's very minor.
I will report back tomorrow after my 70 mile trip back home tonight.

I have had a set of Kumho Ecsta's on my 2005 Coupe with Sport tuned suspension and 19" wheels. The tires are much quieter then the OEM Bridgestones and handling is apparently no different.
I do not push the car hard, just a 50 mile commute each day. I have had the tires since April and have had no issues. They were significantly cheaper  than Bridgestones or Goodyears.

Thanks to both the replies on the kumos. It's good to know that the tire noise is less than the OEM and that the performance difference is minor. Truth be told the only time I really get to do any fun driving is on the on and off ramps. Looking forward to the feed back after the 70 mile trip.
Thanks again,
Doug

Two days of driving and 150 miles afterwards with the Kumho, the tires are MUCH quieter than the OEM, even when the OEMs were new. Ride is much improved and handling difference is there but minor by my definition. The turn-in is not as sharp and precise as the OEM and you loose a little bit of the steering feel while turning. On the other hand, you do not feel every little rock and pebble through the steering wheel either. It reminds me why bought this car in the first place, I wanted a luxury sedan, and it rides like one now.
If you want a sports sedan, I suspect the Goodyear F1 may be more sporty than the Kumho. But for me, the Kumho being $150 cheaper for the whole set and treadwear being better (rating of 600 vs 420), I am thrilled with my purchase of Kumho so far.
Let see how they perform after a couple thousand miles.
