i got 165 15's on the front and mt street drag on the back. and got a flat on a drag tire what size should i go with for both rear tires

 

the same size that's on it now...

 

iam going with a street tire and take the drags off i was thinkin 235 60 15

 

depends on alot of things man lol

what gears do you have? you may not want a tall tire

im running 225 55 16 and i like them. liked them even more with the 3.55s

 

Changing your factory spec tire height will throw off your speedometer. If you are just wanting tires to drive with why not go with factory spec? If you want to race id suggest a 2nd set of wheels with drag radials

 

Well there chico... it would be tremendously helpful if you told us what size tires you currently have. But since that seems to be too ****ing difficult...

Your options are:
225/60/15
275/50/15
225/55/16
245/50/16
245/45/17
275/40/17
315/35/17

These are all stock diameter, and will not affect speedometer readings (assuming your car is setup correctly)
