hey guys im looking for the best size tire for my car for drag racing. ive got a 408 that will spin to about 6500 rpms. 3.73 gears, tko600 with 2.87 first 1.89 second 1.28 3rd and 1:1 4th. im looking into hoosier 10 inch slicks or maybe the quick time pro or et drags from m/t. is there a way to calculate a tire size that will give me the best et down the 1320? i see many guys run a 26 or 28" tall tire but im not sure what to go with.

thanks in advance

Theres not really anyway to determine what tire size will maximixe et, there are guys running 8's on 26x8.5's. With 3:73's Id try a set of 26's and see how that works out for ya

Ive got 255/60/15 MT ET Street drag radials on mine. Now I kinda wish I bought 16's so I didnt have mismatched wheels when driving with the dr's on. 16's in the front and 15's in the rear looks ghetto.

Well for one thing dude you need to get that engine tuned, you can spin that 408 to 7 atleast, get the 26x10s and call it a day, its a pure street car bro, we both know what that car is capable of

i dont trust that motor at 7k..i dont wanna walk the caps of throw a rod...especially with the spray....plus i dont think those heads are big enough for 7k. id like to do the 28s because they have a little bit more tread width and would fill out the wheel well better and would be better for cruising rpms. plus i wouldnt have to worry about spinning the car past 6500 thru the traps. hmmmmm

This is true, good point.

But i dont know dude, those 27's i had barley fit under your GT and then you put that suspension in the LX you might have a little more clearence to fit a good 27" but 28 is kind of out of the question with the 5.5" back spacing on the wheels and a stock tub, you would have to roll the fenders like crazy or tub it.

the diameter wouldnt be the problem..275/60/15s are 28 inches in diameter..and thats what benders dad runs...its the section width...the 275s are 11.10 and the 28s are 12.10...might need a RBH lol

28 x 10.5 M/T ET Drag. They will fit with a little wheel well massaging and will be what you need. You could even use 4:10's. A 26" tire would be way to small with a stick shifting at 6,500 rpm with 3:73's.

thanks EHA..the onyl thing i noticed was they recommend a 9 inch rim minimum..ive got 15x8. the hoosier 28x10s are the same size as the M/Ts but they say the minimum is an 8 inch..what gives?

the inside tub is beat to hell already, you can get away with a 10" rim with a 10" tire but the qaurters gotta be rolled, idk what benders dad has for suspension, his car sits pretty high too and an 8" rim
