Wheel Size Recommendations

68SPRINT · May 25, 2007

I am fitting a front disc conversion kit to my 67 390 fastback so I have got to replace the original styled steel wheels for some bigger ones. I have decided to go for 16" x 7 polished Torque Thrusts. However, I am undecided on the tyre size. I am thinking of going 225 50 15 all round. Is this a good choice?? Or is going for 245 50 15 on the back a better option?

Any help appreciated.

245/50-16 all around will be closer to the original tire size.

I think you are going to have quite a bit of troble fitting a 15" tire on a 16" wheel.

A couple more things to consider:
- I would go to an 8" wide rim, 245's will not fit on 7" rims
- Also, I would consider going to a 17" tall wheel, 16" rims align the rim with the top control arm. With a 17" rim the rim sits above the control arm and allows more backspacing of the wheel. There is also a much better tire selection with 17" tires.

If you are staying with 16" rims, I would go with:
16" X 8" with 4.5" backspacing and 225/50/16 front, 245/50/16 rear (you are probably going to have to grind or roll your rear wheel well lips a little to fit the 245's with this set up)

If you go to 17" rims, you could go with:
17" X 8" with 4.75 backspacing and 225/45/17 front, 245/50/16 rear (Edit: I mean 245/45/17's - Thanks for the catch CarFreak)
There are some people even running 235/40/17 front and 255/40/17 rear with some minor wheel well lip grinding.

Hope that helps some,
Tim

I think you'll have a little trouble fitting 225/245 50 15 tires on 16" wheels. Just giving you a little s**t.

You could do either. It's a matter of personal preference if you want larger on the rear. Personally, that's what I like. I actually went to the MCA show here in Louisville today, and both combos were pretty common. Now, all of those were w/ 15" wheels. I don't know if the 16" would be different w/ regards to clearance issues, or if you will have any difficulty finding those sizes for 16".

Good luck!

What, is this contagious?

I have 245s on a 7in rim right now it just depends on the tire look into the suggested wheel sizes on different tires before you buy them though because some of them won't fit.

another thing to consider is that it's getting more and more difficult to find decent tires for 15" rims

i have 15x8.5" in the rear of my car, and almost nobody makes anything larger than a 225 tread width for 15" rims, at least not in ultra high performance tires
