Tire difference. OEM vs other

Chunkee

The 2007 G35 needs new tires, the OEMS are just the suck at treadwear 140 and 1100 bux.

I found some others one tirerack. Kuhmos LX. They have great ratings even for the car. Specs are listed below; The only real difference is the load rating on the rear set. Would I notice the change during driving?

Thanks.

* UTQG: Treadwear: 140
Traction: A
Temperature: A140 A A

* Rear: 245/45R18

No, you will not notice a difference from the load rating. There will definitely be a significant difference between the frip of tires with a 140 treadwear rating and tires with a 600 treadwear rating however. You'll certainly notice that, but nothing from the increased load rating.

Load it also at maximum pressure for the tires and chances are you won't be upping the PSI to the full 45+ PSI that tires often allow today.

NM...

Frip = grip

those tires are a large complaint against owners (14-15k) OEMs....and they are so costly..I am not going to hot dog a whole bunch and it rains here a great deal and want something with water traction a bit...it does not snow here really at all...never sticks

thanks

No..he just mistyped the word. I am assuming Frip means grip...at first I did not understand. The tires should be good to go...they have great reviews for the car I am putting them on....and hopefully last a lot longer than 14000 miles.

thanks
 
ok, got it

They will last longer but as mentioned 600 treadwear is high. I wouldn't put them on a "performance" car
 
Tirerack.com has a great traction rating system I use all the time when picking tires, if the G has the same OEM's as my Nissan (continental) they are nearly the worst tire you can use, I'm amazed that the treadlife and traction were both so horrible, usually one trades off into the other.

Kuhmos seem to have replaced yoki's as the performance/price favourite, but thats just my perception.

i very much agree with this

i went from 240 treadwear michelins to 460 treadwear bridgestone all-season's on my car, and i can definitely notice a reduction in grip sometimes. if I can notice it in my civic, i'm sure you'll be able to tell in your g
 
i'm never going to put any korean tires on my car. if you want cheap but good performance tires I'd try Dunlop Direzza Z1 Star Spec or cheaper is General Exclaim UHP

note: tread wear is different by manufacturer, each manufacture "rates" their tire against an index value of 100. Just b/c Kuhmo says 600 doesn't mean its going to last 4 times longer than the OEM's

such the sage you are. i have had several sets of kuhmos, never a problem with them...

I am not really biased where they are made...just want good value with no headaches..

Yes, there is some variance, but not a ridiculous amount. It's safe to expect any tire with a 600 treadwear rating to last 40,000-60,000 miles if you keep them inflated properly and keep up with rotation and alignment.

I am looking at Potenza RE760 Sport these for my G35 when my crappy ones need to be replaced. I do live in FL so summer tires all the way

well i happen to drive one of the cars you list as "performance" oriented, and in fact kuhmo doesn't even make tires in my size (or at least tirerack doesn't sell em)

there are problems with these tires, with the sidewalls being to soft and rolling making the tire uneven and having uneven wear issues. But if you corner softly and drive like a granny you should be set. I would not put this on a sporty car though.

pretty good choice

not super sticky but should last a bit longer than the stickiest
 
My father owns two cars - a CRV and a Mazda3. Both were were sold with unspeakably awful domestic tires - noisy, expensive to replace, and they wore out very quickly. He replaced them with better-rated tires - one Michielin, the other one domestic IIRC - that, despite being less expensive, did a better job in every way.

Unless you have a really hot car, the factory probably includes horrible overpriced tires. Go to an enthusiast forum, figure out what they're buying, and get a set.
 
I'd say the majority of people don't care about tires because they only see a car as a way to get from point A to point B. I would just assume that someone that chose a somewhat sporty G35 might not cheap out and would prefer some decent tires.

Then again, my friends mom drive a G35 so what do I know.
