I have a 68 camaro that i want to put 17's on. I thought about the weld XR tuners. Does anyone have and idea if 17x7 with 4.5 backspacing in the front and 17x8 with 4.5"backspacing would work. Tire size 235/45/17 front and 265/45/17 rear. The rear shocks are moved in and the wheelwell lip has been turned up. Stock width rear with disc brakes. I want to run the widest possible without sticking out too far. Any help would be appreciated. Thanks

They will fit. I have 17x8 all the way around, with 4-1/2" of backspacing on all 4.
tires are 235/45/ZR17 on the front, and 275/40/ZR17 on the rear. They don not rub even on hard bumps.

I second Teetoe's comment...

I run 17x8 on all four with 255/45x17 rear and 245/45x17 front.

All wheel have 4-1/2" backspacing.

Now then, that being said...

I need to either get a narrower tire up front, or a 7" wheel up there.

I get a little rub at full lock.

Other than that, there's room, at leats on my '67 to run a 17x9 with 275/40 out back with no suspension/body mods..

TeeToe, how do you like the fit of the 275 on a 8" wheel. I was wanting to put a 245 on an 8" wheel in front and possible go with a little more backspacing like 4.75". And for the rear I was thinking about going with a 275 on a 9.5" wheel with 5.5" of backspacing. Do you think that will work ok?

Well i like the fit. BUT- I do all my own stuff (even mounting and balancing tires) and putting them on an 8" rim SUCKS!!! I should have done a 9" or 9-1/2" rim, but oh well. The 235/45/ZR17 is the BEST combo to use on the front. My car is lowered almost 2" and i drive it HARD. Those tires never rub or scrape at all. the combo you are speaking of should work fine. I'm getting rid of my 17's and going for a 18x8 witha 235/35/ZR18 on the front with some HRE 545's, and some 18x9 HRE 545's with a 285/40ZR18 on the rear. Should be killer.

I went with 17" Torque thrust II's; 17 x 7 fronts w/ 4.5" b.space. Tires are BFG's 235/45 KDWS, In the rear I have 8" w/ 4.75" b. space (this size was not a custom order, I waited 6 weeks for the 4.5's!) and 255/50's
In my opinion, the look is good for a 67/68.
I do get some rubbing on hard bumps up front, but I have a disc conversion on the front that might have pushed out the wheels a bit. The KDWS 255/50 on the rear is 27" tall and fills the well nicely. If yor wheel is an open design like mine, (TTII's have spokes) I'll tell you that the rear drums look kinda dumb with a 17" wheel. Now I want some Baer disc's back there.

John,
Do you have a picture you can post ir email to me of a side shot of your car with these wheels?

I currently have Billet Specialties GT53s on my car in 17x8, but have been considering the TorqueThurst IIs.

Thanks,
David

David, I was afraid you were going to ask for a shot, sorry I don't. And I have my car tucked away for the winter in this plastic tent that I built for it. I will try to post a shot as soon as I can, but did you see the 16's on a '68 in the Bench Racing section? I almost wish I would have done the 16"s,(the 17's are really big and make those tiny rear drums look stupid) but A.R.E. said only 4 1/8" max. in b.s. on the 16" x 7"'s while they'd go to 4 3/4" b.s on the 17" x 7"'s ( I didn't want any rubbing, so I went with the 17" x 7"'s with 4 1/2" b.s. I still get some rubbing too! The 17 x 8's with 4 3/4" b.s. are perfect for the rear, just the right look, in my opinion. If your car is slammed, you might have some minor rear lip trimming though.

I have 17" TT2's on my '69. 17x7 and 17x8 with a 4" backspace. However, I'm running a 9" rear and the width is a little different and this was how it measured out. My tires are BFG Comp T/As - 245/45/17 front and 255/45/17 rear. My car is lowered a couple of inches and I don't have any interference (rear fender lips are trimmed just a little). I would love to step up to 275's in the rear - although I would also want 9-1/2" wheels and that adds up the $$$$ pretty fast.

After doing a bunch of measuring I don't know how you can fit 285's out back? On my car the section width of the 285 tire is simply more than the available space so without airshocks they just won't clear????

I have some pics on my website.

Question

John, I'm trying to decide what size wheel and tire to put on my 67 rs/ss. I have lowered the car 2" all 4 corners with Eaton springs. Budnik emailed me a recommendation of 17 x 7 w/4"b.s for front and 17 x 8 w/4.75"b.s. rear. With your experiences does this sound correct? I'm looking to fill the wheel wells without rubbing. Should I be looking at 16"? Thanks Matt
67 rs/ss 4spd.

Scott- That's weird. 69's should have more room out back than the 67-8 cars do. I'm runing the 275, and i still have about 1-1/2" before i hit the leaf springs. the 285 isn't that much wider than the 275. I feel that it will clear o.k.

Teetoe_Jones,

Do you know if the 275/40/ZR17 tires
will fit on a 1969 camaro with no
mods? Does your car have rearend
mods to accomodate your tires? I
understand, I will need the right
wheel and backspacing.

Thanks for the help.

TJ - I don't know about '67 & '68 cars. I just know that if you crawl under a '69 and check it out - the contact point you run into first is the inner wall of the wheelhouse. My car measures 11-3/4" from there to the lip. (see this link: https://www.camaros.net/forum/Forum8/HTML/000153.html)

Once you move the inner wall - or mini-tub the car - then you'll run into the spring and/or the lower shock mount - particularly if the car is lowered with blocks.

Last I checked, a 285 tire had a section width greater than 11-3/4" - are your less?

Hmm. That makes me think. I am unsure if the previous owner mini tubbed the car. Sure dosen't seem like it, but who knows. I don't have my car to look at since i blew the motor, but i'll have to check the width of the rear tires.
And yes- the 275 should fit with no mods. I don't have a rolled lip, or wierd long 12 bolt rear.

When I saw Steilows Thrasher camaro he had a 285 on a 18" rim with out mini-tubbing, and the wheel is up in the fender so it must be possibble, I guess.
