FEDERAL 595 RSR tires reviews

Upcoming 1st of JUNE is TME time attack. So i decide use back my old FEDERAL 595 RSR that left around 10% of  tread.

tata!!! the upper 2 pieces are FEDERAL 595 RSR 

Then i need to buy 2 pieces new FEDERAL 595 RSR... for the upcoming time attack event.

Below pictures are installing the new tires on my sport rims.

wuhoo!! hot and fresh tire are on the way in~~~

After the tires install to my car, so i test these tires on upcoming TME time attack.

After tested the tires, these tires perform are:

a) very good responsive while enter and exit the corners.

b) tread wear are rated 140, its make these tires are more grip during driving on the road. 

c) tires need to warm up abit longger.

d) front tires left 10% of tread, under-steer alot while on wet track conditions.

this 2 are rear wheel tires captured after the time attack done.

above 3 photos are the front 10% tread left RSR when the time attack is done.

GT RADIAL - CHAMPIRO SX2 reviews

On MAY 4th having a time attack event in MIMC go-kart track. My current tyre are wear out, so i have to looking tire to change. Recently i have heard about the GT RADIAL brand tires on CHAMPIRO SX2 series has alot good reviews. Traction , wear&tear and handling are good... So i give it a try on these tire.

As below are the picture of the actual tire of CHAMPIRO SX2  tread-wear 200 size i choose is 195-50-15. 

the Water trade design are good~ and the compound design look good too.

Before the time attack event ,i has changed 4pcs of CHAMPIRO SX2 for my car. 

After changing tires i tested on wet road condition, its perform very well compare with my previous Nankang NS-2R. 

After time attack event, the result of the tires performance are:
a) side wall too soft, effect the stability of vehicle during cornering.
b) delaying of response during cornering.

TOUGE up hill tested, the result of the tires performance are:
a) need to keep counter steering during exit the corner.

After the time attack event, 2 weeks later MIMC open track day. I have joined to try again with these tires.
After few laps, the result tested. The stability of vehicle while exit the corner keep under-steer until out of the track.

haih~~ push too hard.. hit the stone and the sidewall air leak~  

above pictures are the 2 front tires of CHAMPIRO SX2 sidewall bang the rock and sidewall crack, and another 1 can see the inner structure of the tires~ so 2 of these tires BYE BYE end of theirs life~ T.T
