Well i got a 66 chevelle and was wondering what backspacing should i get when i buy some 15x10 for the rear. I herd anywhere from 5.25 to 5.5 so any info will help.

SSpete67 Jan 7th, 03, 6:55 AM what size tire are you going to run? I have a buddy with a 1967 SS, He has 175X10 and has a 285 tire back there, He's pushed the limit!!! He has 5 1/4" back spacing 1966_L78 Jan 7th, 03, 1:46 PM Not entirely sure on 15X10s, but I would think more toward the 5.5 BS I run BFG 295-50/15 on 15X8 rims... No lip mods, but its pretty tight... I forget the offset I have... ------------------ "Once you go RAT, you never go back..."

I was thinking of running maybe a 5.5 BS and a 295/50/15. thanks for the info. Clint44 Jan 7th, 03, 7:25 PM Hate to be a party-pooper but I'm not sure a 15x10 wheel w/5.5" backspace will fit a 66-67,,especially with 295 tires. Might not be a bad idea to do some serious measuring,first. ------------------ Clint Hooper ACES #1650 Wichita Falls,Tx 69 El Camino (prostreet soon to be protourer) ]http://dalesplace.com/misc/friends/clint_hooper.htm] (http://dalesplace.com/misc/friends/clint_hooper.htm) 91 Callaway Aerobody ZR-1 ht]http://personal.tmlp.com/scorp/vette/images/members/usazr1/purple-9.jpg]ht (http://personal.tmlp.com/scorp/vette/images/members/usazr1/purple-9.jpg) Tempelton Jan 8th, 03, 8:35 AM i run 15x10 w/ 5.5 backspacing on my 66 and a 295 50 15 bfg on my 66 w/ no mods to wheel well or lip Clint44 Jan 8th, 03, 11:30 PM I always thought that 66-67 Chevelle wheelwells had less room than a 68-72. Is everything stock on your 66,including the stock-width rear end? Tempelton Jan 9th, 03, 7:51 AM yep, everything bone stock except the poly bushings. 1966_L78 Jan 9th, 03, 12:20 PM As I said above, I run 15X8 rims , but with the 295/50-15s also, and they also fit with no mods to the lip, stock early 12-bolt, stock wheelwell trim, even used to be lowered very low... I did have to get rims with a custom offset, because stock GM 15X8 rallys are offset wrong for this application... I know the 10 inch rim is wider, but it shouldn't affect the overall width of the tread and the widest portion of the tire... I too have heard that 1968 and up have a bigger wheel well, so I guess they can fit even larger tires... ------------------ "Once you go RAT, you never go back..."

There is not 1/4" to spare on the inside or outside of the tires.

WON't FIT! http://www.chevelles.com/forum/frown.gif http://www.chevelles.com/forum/frown.gif It was like a cruel tease too, since i got to see the tires mounte on my car (looked bad ass) When they let the jack down, the fener lip was right on the tire- no fender rolling could help this it was just waaaay to wide. http://www.chevelles.com/forum/frown.gif So i guess... I'm gonna get new rims. http://www.chevelles.com/forum/smile.gif Screw the settling with tires i don't like business- i'm gonna get what i want... 15x10 in back 15x8 up front... Now i just need to talk to KAA(he has it this way on his 70 elky) to get the BS and Offsets from his rims! ------------------ Ben Rambow NECOA #022 1970 El Camino SS (http://www.elcaminoclassics.com/code/rambow1.htm) My old 1969 El Camino (http://www.chevelles.com/feature/july2001.html) Clint44 Jan 11th, 03, 12:42 AM Use the 15x8's on front with a smaller tire and get some 15x10's with 5.5" backspacing. That should fix you up. ------------------ Clint Hooper ACES #1650 Wichita Falls,Tx 69 El Camino (prostreet soon to be protourer) ]http://dalesplace.com/misc/friends/clint_hooper.htm] (http://dalesplace.com/misc/friends/clint_hooper.htm) 91 Callaway Aerobody ZR-1 ht]http://personal.tmlp.com/scorp/vette/images/members/usazr1/purple-9.jpg]ht (http://personal.tmlp.com/scorp/vette/images/members/usazr1/purple-9.jpg) BrianL Jan 11th, 03, 1:11 PM I'm leaning toward a 15x8 with a 4 1/2 backspace and a 275-60 on the rear and a 15x7 4 backspace and a 215-70 on front for my 67. I researched it and found this to be a nice combo. ------------------ If it's too fast your too slow!!!
