16" Wheel fitment question

[UOFLcards]

Ok. I want to clear something up before I place my order. I am going to be going with the REV classic chrome 100 wheels for my 1985 Grand Prix. They have 4.0 backspacing and 0 offset. I have been debating on the 225/50/16 in the front and 245/50/16 in the rear as I like the wider look in the rear. Or I could just go with the 245/50/16 all around. Would I have rubbing issues with the 245/50 all around?

My only concern about going with the 225/50 in the front and the 245/50 in the rear is that the 245/50 is almost an inch taller than the 225/50 (25.6 vs. 24.9). My GP already sits quiet a bit higher in the back as opposed to the front is and I don't really want it to looked jacked up in the back. What would be the best to go with to have a nice stance without the rubbing issues? I want to clear this up before I place my order.

Thanks for the help in advance.

I am using IROC 16" rims... which have alot more backspacing and clearance issues thatn the ones you are ordering. They have 4.75" BS in front, and 5.25" BS in rear. So I am running them opposite (front in back, back in front). To run them this way, I am using a 1" adaptor on front at the 5.25" BS wheel, and 3/8" spacer on back at the 4.75" BS wheel. Which means, I am down to 4.25" BS front and 4.375" BS back.

With your wheels, at 4" BS, and 0 offset, I see almost no issues. The only issues that will arrise is if you try to go past 4" or 4.5" BS

I am using 246/50R16s all around. This causes some rub in the front at full turn, which is likely caused by the 4.25" BS. You might experience this with a 245/50R16 infront as well. The rear, you should be fine.

But while we're discussing tire sizes... In my opinion, the 245s look great in the front, they fill up the wheel well nicely. However, the 245s look dinky in the rear, and often wish I had something larger.

what do you think?
front

rear

overall it looks fine, but I still think at some angles, the rears look dinky

I am due for tires, and I am now rethinkin my choises... I am considering keeping the 245s upfront, but going for 255/60R16s. This size will fill up the rear a little more and look more proportional.

Thanks for the response.

Yea. I can see where you are coming from. You have alot of open wheel well in the rear. I just want to make sure I have no rubbing issues, either up front or in the rear. Up front is my main concern during turns and when hitting bumpy roads. My options could be going with a 17" wheel instead of a 16" or I could maybe go with the 225/50 up front and the 245/50 in the rear. That might give it more of a balance as opposed to up front it looking full and out back it showing alot of space in between.

Or I could go with the 16" in the front and the 17" in the rear. Choices, choices.

GBodys are big cars, so even a 18" wheel looks proportional...
... if you have the choice, go with 17s. The only tricky thing with 17s is it's often hard to find small back spacing, so people are forced to get skinny ones that look funny just to avoid rub issues.

If you can, a 17x8 up front, and 17x9 in the rear, both with 4" BS, 245/45 tire infront, 275/45 tire in rear.
it'll fill up both wheel wells, you won't have rub issues, and it'll give you a nice stance that doesn't look too crazy.

if you know Crash from this forum, he's running 17s all around with similar sizes, and it looks great.

I agree that the 17's would look more proportional but things are tight right now money-wise. Right now I can get the 16's for about 100 bucks cheaper than the 17's and when you factor in the difference price-wise for the tires as well you are looking at a pretty heavy difference in price. I do agree the 17's would fit better when talking about the overall stance of the ride and filling in both wheels wells though. I have alot of upgrades I want done with this car and the money I save on wheels and tires from 16's to 17's could go to other upgrades I want for the car. Paint, dual exhausts, new interior, etc.

When talking about the 16's how would it look as far as stance and overall with 225/50/16 up front and 245/50 in the rear? Like I said I like a little wider rear look. I just don't want to run into alot of issues with rubbing, especially in the front when turning the wheel.

I'm open to any and all suggestions. :?

Thanks again for the replies. Keep them coming. All up for any and all suggestions and comments.

This would be my setup:

REV classic chrome wheels:

Kumho 225/50/16 up front:
http://www.performanceplustire.com/prod ... tireDataID[]=4027

Kuhmo 245/50/16 in the rear:
http://www.performanceplustire.com/prod ... tireDataID[]=4028


Or I could go 245/50/16 all around.

Again. Choices, choices.

does anyone made a 225 with a 55 series wall? I feel like the 50 series sidewall would be too short. The 245/50R16s will be fine in the rear.
If there is slight rubbing, just use a small spacer, like a 1/4" or so. Although, you might need extended studs to catch enough threads with the lugnuts.

My wheels are 16x8 with 4.25 backspacing and 0mm offset. I have 245/50R16 BFG g-Sport tires all the way around. With the F41 steering box it maybe rubbed once or twice, but the alignment was questionable on the car after I put a different steering box in it.

Are you stock right height? That can make a difference if you will rub or not. Out back you will be fine you'll have another inch or two to play with. Unfortunately I think 245 is the widest tire for a 16" wheel.

I can not seem to find a 275/45/tire in my price range, especially with the extra price I will be paying for the wheels going from 16 to 17".

I seem to recall a thread that Crash posted in before stating that he rides on 255/45/17 tires all around. I like his stance on his car and like the way the wheels fill up the wheel wells. They have the REV classic 100 in 17x7 as well with 4.0 backspacing. As well as 17x8 with 4.5 backspacing.

I may have to stick to the 16" as it fits in my price range. Going the extra cost in the wheels is not too big of a deal but doing my research it looks like the price of the tires going from 16 to 17" is a big difference in price.

And no I have not seen a 245/55/16 tire that I can recall in my research.

 

[khan0165]

you're right, 17s can get pricey... even if you find a cheap set of wheels, the tires themselves will cost alot. And if you try to save on tires, the options are shitty foreign brands like Falken.
... so with that in mind, 16s will be well enough for your setup.

you are correct, there is no 245/55... But I was asking about a 225/55, which I believe would be closer to the height of a 245/50.

and I think you are correct about Crash's 255s as well, my bad...
275/40s are most common, I think a few brands make 275/45s. In either case you could stuff them in the back if you were strategic with backspacing and ride height, with no problems.
