Generally "people in the know" post reviews and comments in various car and motorsport forums.
These tires have been out for over a year which is more than enough time for there to be some decent reviews from people that have tried them on track.
While I'm sure they're decent FOR THE PRICE they're most likely not the amazing tire you make them out to be.
Also, if you're going to make the claims you've made about how good these are and also insinuate that people spending more money on well known PROVEN tires are wasting their money then maybe you should take the time to back up your statements. Or, more likely you couldn't find any real reviews on these tires.

 

I'm not trying to be a dick, believe me, if these tires are as good as you say I'll buy a set but only after I see some real proof as to how good they are.

 

A big +1 for SimplyTire from me. Allen is the Michael Jordan of tires and can make great recommendations based on your car, tire size and type of driving you do.

 

Just wanted to say that I bought some Michelin Pilot Super Sport summer tires for my rx8 and they are amazing. It's almost like a mod to my car. I ended up spending about $1120 before rebate. (that's install and spacers and tire disposal - everything). The michelin's are good for 50,000km whereas a lot of the options that are a few hundred cheaper are only good for 30,000km. So technically they are cheaper per km.

Anyway... my old tires... BF GoodRich GForce... I used them about one season too long... and they were so hard. The ride was really rough. With the new tires it's like a new car the ride is so smooth. They stick well in the rain too.

 

Fair comments. Did some research to provide some 'facts'

Nankang is a Taiwanese brand and targeted for their domestic market, much as goodyear is for US. Its not a bad for the price...but longevity is still the issue with most new tire companies, lacking in technology, data & racing knowledge ...including Kumho and Hankook

I just picked up a set of 225/40/19 Ventus RS3 for my 2010 R3 from tire rack for $560 (including taxes and shipping).

I'm currently running the Michelin Pilot Super Sports and love them, but had to pick these up as they were a great deal. The Hankooks will go on next summer.

 

My former RX-8 rims with Toyo T1R summer tires are still running on my daughter's 2003 Mazda6. Likely the last of the tread this season but still remarkable longevity and I still like the looks of them.
