Largest tires and rims that fit on STOCK 1969 Camaro

Hi,

I have a stock height 1969 Camaro and I have been looking through the site to see if I could find out what the largest size tire and rim will fit without any rubbing issues.

I am thinking either one of two combos

18 x 9 in the rears with 4.7 BS with HANKOOK - VENTUS V2 CONCEPT H437
17 x 8 in the front with 4.5 BS with HANKOOK - VENTUS V2 CONCEPT H437

Or

17 x 9 in the rears with 4.5 BS with HANKOOK - VENTUS V2 CONCEPT H437
16 x 8 in the front with 4.5 BS with HANKOOK - VENTUS V2 CONCEPT H437

Can some tell me if they have either of these set ups and if there are any issues with rubbing. Remember I have a stock height Camaro.

Thx,

Joe

Re: Largest tires and rims that fit on STOCK 1969 Camaro

Can't really say if you'll have rubbing all the way around with those wheel choices since you haven't provided any tire sizes on any of the wheels!

That said, to best center your wheels and tires in the stock wheel wells you want a positive 6 offset. Use this chart to see what backspacing you need with different wheel widths to give you that positive 6 allowing you to put the widest tires possible.

Re: Largest tires and rims that fit on STOCK 1969 Camaro

And since that chart doesn't show it, 4.75 would be best for the front 8" being considered.

I know that chart has been around a while but I wonder why it skips 4.75

Most likely you will need disc brakes to run 18 and 17 inch wheels.

Re: Largest tires and rims that fit on STOCK 1969 Camaro

I think the 17x8 and 18x9 is a very nice fit for the first gen Camaros. It offers a staggered setup and matching tires should be very easy to find in the different diameters. You won't have any rubbing issues on those sizes, as long as you have the right back spacing. Let me know if I can help you out any with the wheels. What wheels in particular did you have in mind of going with?

In my opinion, you might have some rubbing issues on the rear with that backspace. Typically, I would go with something a little more tucked in.

4.75 is a good backspace up front, but have used 4.5 before. Depends on how low the car is. The plus 6 offset on the rear will be good, and allow for a 275 rear tire on a 9" wheel.

Re: Largest tires and rims that fit on STOCK 1969 Camaro

Joe, 9" in the rear will be no problem. 8" in front also will be fine, especially if your car is not lowered. I am currently running 9.5" in the rear with plenty of room.

Re: Largest tires and rims that fit on STOCK 1969 Camaro

Thanks for all the help on this so I have been doing some searching and found these tools to be very helpful since I was trying to get as tall of a tire and rim comb as possible.

http://tire-size-conversion.com/tire-height-calculator/

http://www.customwheeloffset.com/tir...et-calculators

http://kgm.tiwing.com/calcs/tiresizecalc.htm

http://tire-size-conversion.com/tiresizes/

I currently have:

Front 235/60R14 = 25.1 x9.3R14
Rear - 255/60R15 = 27.8 x10R15

The new setup I am going to go with ( I think is)

Front - 235/50R17 = 26.3x9.3R17
Rear - 255/50R18 = 28x9R18

Rims will be AR605M Torq Thrust M Chrome if they come in the correct back spacing. I need to check on this.

Anyone have pictures of their setup similar to this I am trying to get a visual on how this will look.

Thanks again everyone.

Re: Largest tires and rims that fit on STOCK 1969 Camaro

I don't think you'll find a Torque Thrust M in an 18x9 with the right backspacing. There are several other brands with a similar design though.

Also, you'll probably want to go with a 45 series front tire and a 40 series rear on a 17/18 setup.

***edit***
Actually a 45 series front and rear would probably be better. With a 45 series up front/40 series rear, you'd have more sidewall in the front than the rear which would look odd.

Actually this is where it's time to do the math: Example -

245/45/17 tires and 275/40/17 tires have the same size sidewall. Both tires are 25.7" tall minus 17" wheel = 8.7" / 2 = 4.35" sidewall...

There is lots of room for a little give and take, having the same sidewall looks the best but; another example - my 235/45/17 and 255/45/17 tires have a 4.2" and 4.55" sidewall, just a little more than 1/4" difference and it doesn't detract from the look. Once you start staggering wheel size you really have to let sidewall size fall where it may if you want the widest tires possible. A 275/35/18 and a 245/45/17 for example are 1/10" off in overall height but the 18 would only have about 2" of sidewall and the 17 would have over 4" of sidewall. You'll need over 3" difference in tire height to run the widest possible tires on a 1st gen with a 17/18 stagger and dial in the sidewall height as close as possible.

Here's a side view of my car...

What size wheels? tires? backspacing? Looks nice but remember the '69 has a flat top wheel well!

Re: Largest tires and rims that fit on STOCK 1969 Camaro

Dennis, yes 67-68 wheel well shape is a tad different. Not that different though unless he is completely maxing out space to the inth degree.

I am running FRONTS 17x7 & REARS 17x9.5's

Plenty of room all around.

John68,

Stock = not lowered, not tubbed, no drop axle...
