Hi guys from a new member thanks for all the welcome's. I have a question. I have a 1982 monte carlo named (diamond in the rough) that I have set up for drag racing for fun not professional. The engine is 383 stroker with all the trimings, my problem is hooking up off the line. The car has a 373 grand national rear end with adjustable upper & lower control arms & lower control arm extensions, a bow tie extreme duty 2004r tranny with a 3500 stall non lockup converter & aluminum drive shaft. It presently has 255x50x16 bf goodrich dot drag radials mounted on 8" rims with a backspacing of 4.5" & the tire diameter 26.1" tall. The distance from the inside tire sidewall to the frame is 3/16" with a 1/8" spacer tires inflated to 15lbs. According to manufactuer specs the tire has 10.3 section width. Goodrich offers a 275x5015 that has a 11.3 section width and 26.1 diameter when mounted on a 8.5" rim. I would like to use this tire on a 8" ( still within the manufactures specs 7.5" to 9.5" rim) which would cause a little more buldge according to tire rack but they didnt know how much more buldge. My question is has anyone used this tire on 1982 g body & if so what back spacing worked. I would like to use 3.75" bs but not sure if I should go to 3.5" bs, if any one has 1st hand experience on this combo any info will be greatly appreciated.
Thanks Tom

 

Welcome to the MCF

 

I am not sure on what size of rim I have, but I'm sure I can measure tomorrow for you. I currently run 275 60 r15 nitto 555r drag radials and have no issues, which is the biggest you can go without them rubbing or sticking out.

 

Anybody have an idea whats the largest drag radial I can put on my 2000 monte?
