I could use some tire help. We are a roadrace shop and we are building my wives 99 FRC we are using a 500RWHP motor with another 300 direct port shot the car should be in the 3100# range. We are converting it to a 4L60 with a brake with a lot of help from RPM Transmission.
I am thinking I will probably need to go with a 16 inch setup and bias plys but I have heard of guys having great luck with the 345-18 drag radials. I already have several sets of 18x12 ccws so it would be nice if I could use the 18's.
I guess the main question is how much if any would I be giving up in a well preped car on the radials VS bias plys?
I should also mention 15 inch wheels will not clear the control arms.
Thanks, Dale

I think you should get as much sidewall as you can under there. I'd go for some custom 16x10 Bogarts with some 28x10.5 Hoosier QTPs probably.

I have narrowed it down to 3 choices I think.
MT DR's 345-18's
M&H DR's 345-18's
MT Bias Plys 28x11.5x16
If anyone has any input on the comparason of these three I would greatly appreciate it.
Thanks again, Dale

500 w n/a plus a 300 hit is not gonna get down the track at all with an 18 inch wheel.
If you want to drag race... best start looking at a 15 inch rim setup, and change what is nessassary to get it to work, especially with the power level you're looking at.
Either that, or get ready for some seriously dissappointing track times. Like I wouldn't go telling anyone you're hitting it with 300 when you're at the track, I'd be telling them it's a 100 shot, becuase you'll be running times like that's what you're hitting it with.

There are a few guys running mid 9's on the 18's here are a couple http://shinkaze.com/2008/09/ips-moto...te-z06-932156/
I dont know what their 60 foots are so I dont know if they giving a lot up with the 18's.

You're running separate street and race tires. Are you changing at the track or trailering? If so, don't compromise. Run the most sidewall you can and bias plys will flex more.

C'mon man you came into this section asking for help and you are just ignoring people. I really hate it when people ask for help but won't take any advice. Why ask for help in the first place, you are only wasting your time and others. More sidewall = better / safer
26inch tire-16inch rim= 10 inches of sidewall
28inch tire -18inch rim= 10 iches of sidewall
So I guess my question should have been, will a wider DR with the same sidewall work as well as a narrower Bias ply.
But I dont want to waste any more of your valuable time so a will order a set of each and see what works better.
Thanks again to everyone who actually tried to help, Dale
