i bought 2 275's for the back of my car should be here today i was wondering from my stock tires will i notice a difference ???

 

Did you order the Nitto N555R drag radials or just regular street tires? If you ordered the radials you will be pleased I put them on my car (02 SS) last month. I have not spun once at all even when I floored it from a dead stop on an old country road. ASR was off too. On the strip lower the tire pressure and you will do great. Be careful in the rain though they will slip on you. The street tires should be about the same as the stock ones I guess.

 

is your car severly underpowered?

honestly they are more like a street tire than a drag radial, i havnt had any problems with them in the rain and i can spin them really easy and have to smoke them up for about 10 seconds for them to stick to the track

my next set of drag radials will definatly be the mickey thomson ET street radial

 

yeah i got the drag radials and it rained today they werent to slippery but i didnt get on it much i did do a run on are road before it rained an was very happy with how i stuck i did have to light them up before i stuck but after that i did notice a diff in my hookups

 

No my car is not unpowered unless you mean stock. I dynoed when I got it at 308 rwhp so from what I can tell it is about right. And if I was underpowered I wouldn't be slipping in the rain. And when I tried to spin them I had been driving awhile so they were warm and I drive on them at 20 psi all the time. What is air pressure at for daily driving? In the rain with a lower air pressure I might not be treading water like I would be at a higher pressure. If the tires are cold then I can slip and maybe the track where I am at is in better condition than yours is. When I ran they had just tarred the staging lanes.
