Looking at 17" American Racing T70R's but not sure about BS

Postby V6UnderPressure on Mon Jun 11, 2012 8:12 pm

See link below:

It appears I have three options, but I cannot say I am comfortable with any of them. These will be for my 87 442 with Hotchkis TVS system lowering the car about an inch. The three options are as follows:

17x7 w/4" of BS
17x8 w/4.5" of BS
17x9 w/5.0" of BS

Has anyone run any of these on the Cutlass with no issues? I know I can run the 17x7 or 17x8 but I don't want the wheels tucked in too much. Anyone got any photos or experiences with these sizes?

I have 17x8 with 4 3/4 BS on the front of my car. My tires are 245/45/17 and they rub at full lock. I am planning on installing the LS brake mod on the front and that should move the wheel out about 1/4. That's about all I think I have room for, so I think the 17x8 should fit well on your car. Do you know what size tire you are going with? My rear wheels are 17x9 with a 5 1/2 BS. My rear tires are 275/40/17. I am using a 1" bolt-on spacer to bring the wheel out to be about as good as I can get it. I also had to roll he qtr lip. There's some pics in my gallery. Here's a link to the website for my wheels.http://www.coyswheel.com/coys-c67.html
Hope this helps.

I have seen this car and imo the wheel & tire sizing are perfect.
If I have anything to add its that if you have more serious power under the hood consider opting for drag radials in the back. Ive had good luck with Nittos & M&Hs.

I love the look of your wheels and the fit looks perfect. I just don't want to use any spacers. I think I'm ok going with 17x8 on the front with the 4.5" backspacing. It's the rear I'm worried about. Id like to do the 17x9, but just not sure if I can get away with the 5" BS. As far as tire size, I'll put whatever will fit. :mrgreen: I don't need to have a big fatty in there, as I am just trying to get a small bit of the pro-touring look.

I agree on the Nitto Drag Radials. The sidewalls appear to be harder than most and actually ride like a regular tire. I have them on my 87 GN which has 17x9 & 4.5" BS. And they fit perfectly. A buddy of mine had Mickey Thompsons in the same exact size as my Nittos but they had a bigger bulge and rubbed. Funny how it makes a difference from brand to brand.

I am actually strongly considering a 17x7 front and 17x8 rear setup. I really want a staggered setup and this malibu in the thread below got me thinking and it should give me plenty of room to prevent rubbing:

viewtopic.php?f=5&t=35512&p=300477&hilit=17x7#p300477

Question is, what tire size. I was thinking 225-45-17 up front with the 17x7's and 245-45-17 in the rear for the 17x8's. Thoughts? I'm getting real close to pulling the trigger on this wheel order. ;)

I have 17x8s all the way around with 225/50 up front and 245/45 in the rear and it looks good with no problems at all

I like your set up what backspacing are you running, FT and Rear.
I am looking at a set of Coys C5 17 X 8 but I am not sure on the back spacing.
I am thinking 4.5 all the way around.

Same size tires with the 17x7 & 17x8 ie 245/45 & 275/40. Nothing wrong with those rims on a G at all. The 225s & 245s look too short & small on a gbody IMO. More sporty economy car size than muscle car size.

What offset? Is your car lowered?

I'm gonna be going with 17x7 up front and 17x8 for that slightly staggered look. My car also has a hotchkis suspension kit so its lowered and I want the extra clearance. I am going 225-45-17 on front. But I am trying to figure out the rears. I either want to go 245-45-17 or 255-45-17. The 17x8's have 4.5" backspace, so I am not sure if I could get away with a 255, or that it may look stupid. Anyone tried that? I kinda have a feeling that the 255 would rub...

thats pretty much the same set up i have but 17x8s in the front and i was thinking about trying the 255 but decided to just stick with the 245s because i know they work and dont rub. i know a guy where i live who has a malibu with 265/35 and not sure what size rim or backspacing it has but its either a 17 or 18 and he said it only rubs when he goes around corners fast.
