What are the biggest wheels for the front?

Just bought some torque thrust D's and was wondering what the biggest tires that will go on the front. The car is torn apart so I dont know if they will fit. The rims are 15x8.5 and it currently has 255/60's. Looking to have the deep dish look on the front.

Any help would be appreciated.
Thanks.

Re: What is the biggest wheels for the front?

I think you may have clearance issues with an 8.5" rim up front, hopefully someone with a '67 can chime in with advice though. What's your front suspension and steering setup, esp ride height relative to factory spec? Also what is the backspace of the Torque Thrusts?

Re: What is the biggest wheels for the front?

I think 255's are stretching it, and so are the 8.5" rims. Unless your front end is riding high and the wheels stick out the sides some.

245's rub on a lot of cars, unless the backspacing is perfect even on an 8" rim. 235's are generally pretty safe.

Re: What is the biggest wheels for the front?

Thanks for your help. The car is dropped 1.5in with hotchkis springs in front and rear. Stock steering set up. Got the wheels from a guy with a vette, so they are all the same size. I figured it was pushing it, but never hurts to ask. I am just wanting the widest one I can get on the front. Looks like 15x7's and 70's.

Thanks again.

Thanks again.
70's are even taller and will cause even more problems at that width. I think 60's look best on a 15" rim.

You should be able to run 15x8's with the correct backspacing, then a 235/60/15 should fit alright. Maybe a 245, but I would only try that if someone would let you mount it to the wheel first for a test fit.

Check out the stickies at the top of this forum. There was someone running 235/60/15's on a 15x7 up front, and 255/60/15's on a 15x7 in the rear.

Half way down the page, but no info on backspacing: 67's https://www.camaros.net/forums/showthread.php?t=153144

68's: https://www.camaros.net/forums/showthread.php?t=153193

Remember the bigger the tire the harder to turn. Matter more with the old manual hot rods though.

I Like manual steering though, mash it and turn sideways, it straightens out by itself!!!

Re: What is the biggest wheels for the front?

235/60/15 on the front with Crager Eliminator's 4.25 back space front and 255/60/15 rear on 4.5 inch back space.

Front lowered with 1.5 inch drop but not settled in pics with hotchkiss and rear is lowered with hotchkiss 1.5 inch drop. Not sure how much it will settle.

Re: What is the biggest wheels for the front?

Carl C has some good info on his page you might be interested in. Look for the heading "How to swallow 275/40/17 in all four corners"
http://www.geocities.com/casanoc/

keep in mind, you can use the same process to fit different rim, sidewall as long as the height and width of the tire are the same.

Re: What is the biggest wheels for the front?

I don't know how different 67 is from 71..

On my 71, i used to run 8.5 enkei wheels with 225/60/15, and 245 in back... now i am running 245/35/18 in fronts on 8.5 and 285/30/19's on 10 inch in back..

Backspacing is the key..

285's won't fit on a '67 unless you roll the rear fenders. Like I said, 275's will fit, but backspacing has to be right on.

I have the SpeedTech UCA's and LCA's. You are looking at close to $1100 if you shop them well. Also, I believe Carl used the High Clearance UCA's which you aren't supposed to be able to buy without also buying their subframe for another $2200 bare, or $4700+ complete. It didn't sound like the OP was looking to spend that kind of money.

Even with the 245's up front I had to use the adjustable steering stops on the LCA's to limit steering so I wouldn't rub on hard corners or backing out of the driveway. With 275's up front you would lose even more turning radius, just to pick up a little more traction. I don't think it's a worthwhile trade off unless you are going to track or autoX the car. On a street driven car, it's just not practical.
