General Buick Tech / Rear Tire DR Size for daily driver

« on: April 04 2017, 09:40:33 AM »

Hey Guys- new to this board, owned my '85 for 2 years, just converted to 87 intercooled. TE44 turbo. Now I need traction! I have 17's Torq Thrust on it now, really like the size and look. Rears are 255. I need to go with drag radials.....wh at size works best? I can get 275/40-17 Nitto 555's to keep the same rim size, might need spacers though (limited rim sizes). Do I need to go back to 15" to have some sidewall for traction?
Will the 275's fit stock fenders (not rolled)?
