Rear 9.5" wide rim with 5.5" BS

Or would I be safer with a 9" rear rim with ?? backspacing?

I have stock front discs for now and rear drums.
As I said, at some point in the future I'll be lowering aprox 2", probably with the ridetech setup.

I want to get as wide a rear tire as possible while still not getting too close to rub.

I'm also thinking I'll want to go with a 26" or 27" tall rear tire.

Ideal backspacing for a 1st gen:
18x7 w/4.25" BS
18x8 w/4.75" BS
18x9 w/5.25" BS
18x9.5 w/5.5 "BS

If you are looking at wheels that list an offset, you are looking for +6mm to be dead center in the wheel well.

A 245/40/18 is about as big as you can go up front, and you still may have some rubbing issues. 275/40/18 is about as big as you go in the rear without tubs. Obviously each car is different, and GM tolerances were questionable back in the day. Some cars seem to get away with slightly bigger, and some have had issues with slightly smaller.

Oooh, I'm liking the looks of those.

I think I'd be fine with the BMW bolt pattern. It's only .025 different. Probably barely out of the tolerance stackup of the old hubs and wheels anyway.

I have to figure out the offset to bs translation again though.

If they are way out you can buy an adapter...5 x 4 3/4 base with a 5 x 120 lug spread.

Calculator here.

Thanks Flash, I'll check them out.

Rears are tight both inner and outer. I was getting a little contact with hard cornering loads with urethane from spring bushings and new OEM rubber rear bushings. Just installed urethane rears and I'm guessing the contact won't be an issue as they are much more rigid. My wheel opening to ground measurements are 24.25" front 25" rear. The rear inner lips have not been rolled, I had to massage a couple high spots on the inner sheet metal. That said all these car vary to a certain degree.

OK, so....from what I've gathered so far...
If I keep my eye out for 18x8 w/4.75" BS for the front I should be ok and (I hate these metric tire sizes) I should get maybe the next size smaller (width) tire than 245/40/18 ?

For the back I should be looking for 18x9.5 w/5.5 "BS and maybe look for the next size smaller than 275/40/18?

I'll have to do some more research and relearn how to decipher the tire sizes again (it's been a while since I speced out anything). Then I'll see what I can come up with. I do have a 4.10 rear and probably really should have a 3.90 so if I go a bit larger in diameter in the back I may have to go a bit narrower.

Those are pretty darn reasonable. I like some of them too....which is always a plus! LOL

Looks like their SQL server is screwing up though...

Code:

1054 - Unknown column 'psw.products_specs_bolt_pattern3' in 'where clause'



select * from products p inner join products_description pd on p.products_id = pd.products_id left join products_specs_wheels_new psw on p.products_id = psw.products_id where psw.products_specs_diameter = 18 and psw.products_id = 1968 and ( psw.products_specs_bolt_pattern = '5x120.7' or psw.products_specs_bolt_pattern2 = '5x120.7' or psw.products_specs_bolt_pattern3 = '5x120.7' ) and ( psw.products_specs_width >= '8' and psw.products_specs_width <= '9.5' ) and ( psw.products_specs_offset >= 6 and psw.products_specs_offset <= 0 ) and pd.language_id = 1 order by psw.products_specs_diameter, psw.products_specs_width, psw.products_specs_bolt_pattern, psw.products_specs_bolt_pattern2, psw.products_specs_offset ASC

hmmm.... Are they a reputable dealer?

Not quite my style. But thanks anyway! GLWS

No problem. Just saw you wanted a really good wheel for a great price so I thought I would throw it out there. Good luck in your search.

Understanding tire sizes are as follows:

275/40/18

1st number is width = 275mm wide (divide by 25.4 to find inches)
2nd number is sidewall height = 40% of 275mm (from lip of wheel to edge of tire)
3rd number is wheel diameter = 18"

A narrower tire would be a 265/40/18, or a 255/40/18
A tire with less sidewall would be a 275/35/18

Simple right?

Now the confusing part...Keep in mind that since the sidewall is a percentage of the tread width, a 265/40/18 will be 10mm narrower and have 4mm less sidewall than the 275/40/18. That translates to 8mm overall shorter tire since you have to count both both sidewalls (above and below the rim).

If you really want to play it safe, you can run: 225/40/18 and 255/40/18.

But that's no fun.

A still fairly safe option would be: 235/40/18 and the same 255/40/18's. If your bs is correct, these sizes will fit the majority of 1st gen's without issues.

*265/40/18 isn't offered by every manufacturer, so that's why I didn't suggest those.

Safe sucks! You should be OK with 245's and 275's. The front fender to inner fender bolts at the top of the wheel opening should be replaced with pan head allen bolts if the car is relatively low.....assuming front track width is stock. I'm running Kore3 hubs and IIRC they push the wheel out an 1/8" from OEM and I'm OK.

This photo will give you some idea of 4.75-5.5 and 245-275 clearances:
