I had a set of the INVOs on my 02 e46 M3 and I loved them. By far the quietest tire Ive ever experienced. Very comfortable ride and minimal sidewall flex on mediocre corners. Probably too soft for hardcore track duty but great all around performance. Wanted a set for the G but the rears were on back order all over the country. BTW like most tires in this class they suck in the snow.

 

i have invo and the rears get a bit roary at freeway speeds. its not too bad though. the fronts are dead silent and the grip is fantastic.

 

please don't get the nankangs. i got them for the fronts. i have like 10k. on em. Loud as ish bro. I don't even drive all that crazy. pos imo.

 

I have noticed tire roar, but this is due to known suspension issues on the G. Tire cupping is a common problem with the rear tires of the G. Apparently, there is a TSB about using new settings for the rear suspension. When I go in for my next alignment, I'm going to find out about chaning the toe settings to reduce cupping.

But this issue would have happened Nankang or not, so I'm still not sold on them being bad tires.

Tire grip is still strong and I my overall impression has been positive.

 

I plan on getting nankang's for my rears. I have one nankang ns1 on the front. I went to discount tire to buy a new front tire because my alignment was so off i had less the 1% tread on my inner tire. All of the "name brand" tires where sold out so i had to go with something. I have driven over 4k on them so far with no issues

 

I know this thread is old, but I thought I'd throw my 2 cents in on the tires:

I had a flat in one of my rear tires (not a Nankang) and i basically shredded it trying to get to a parking lot. Since I had good tread on my front tires, I decided to go the cheap route on some replacement rears (2 tires) and chose the Nankangs (NS-II). I've gone between 7-8k miles on the tires and they are completely cashed. The tires may have been slightly underinflated as the wear is a bit more excessive on both outer edges, but the center of the tire is effectively gone as well - wear is really pretty even overall.

I had 19 in tires. I'm thinking that is part of the culprit. From the Nankang NS-II specs:
# UTQG rating : 320 A A (for 15 thru 18 inch)
# UTQG rating : 200 A A (for 19 thru 22 inch)

For $250 shipped (for 2), they weren't bad, but definitely not the most durable tire I've ever had. I only saw the 320 number when I did some quick research before buying these - that's really my own fault, but I needed to get back on the road. The Pilot Sports on the front STILL have life left, but I'm going to just replace everything now.

Just wanted to make everyone aware of the size specific tread ratings since I missed it.

 

bumping this thread cause I searched it. I have these tires on my car and I have this same noise, very loud and annoying. Did you ever find out a way to get rid of it? I took it to two mechanics and they couldnt figure out how to solve it! Any advice on how to fix this would be greatly appreciated, thanks!

 

Ok, I have had many tires on my coupe from PS2, Neros, to Nexen and Nankangs.

Yes the Nankangs are "cheaper" tires and I would not consider them for aggressive driving. BUT, they are a decent tire that passes all mandatory safety tests and production requirements.

The reason for that awful tire hum is not necessarily due to the Nankangs. Our cars seem to hate directional tires. It just makes the tire drone even worse.

If I could give you any advice on reducing tire hum it would be to have camber/toe correctly adjusted, buy NON DIRECTIONAL tires and rotate them side to side every oil change (3k miles)

Other than that, there is little to do when it comes to reducing noice on a fat, low profile tire for our cars.

 

From what I can tell, once the cupping starts taking place, it is too late to save the tires. You'll need to keep a close eye on your alignment when the tires are new to reduce the chance of cupping and tire noise.

 

Hmm interesting. The noise is bad, really loud! Especially when I break the noise is ridiculous haha. When I took it to my mechanic he said the tires were scalloped so I was curious how to fix it but they couldnt find a problem.

So is there a special alignment I need done, or just a normal one? I had the alignment done when I first bought the car 2 months ago and the tires were new then.

 

I had nankang tires on my 350z for 2 years with no problems what so ever, very reliable from my experience for a "lower grade" tire

front 245/40/R18
rear 275/35/R18

 

What site did u guys buy these tires? I need new rears might try it out

 

It has been a while since I looked it up, but I think there is a TSB with new alignment specs that should be used. You might have to do some more research to track down the specific TSB. Feel free to post if you find it.

 

Im gonna sound dumb but what is a TSB?

 

Technical Service Bulletin. If there is a known and repeated issue, manufacturers will create a TSB to give to their in-house mechanics to take a look at. In some cases, they are covered beyond the warranty. If a TSB is written about something, it usually means it is seen in a lot and is a manufacturer's defect.

Tire noise has a been a known issue in the G35/350Z and the TSB if I remember calls for new alignment settings to reduce tire noise and uneven wear.
