Default 91 SSE Bolt Pattern

hello everyone, i was wondering if any of you knew what the bolt pattern was for a 91 SSE? and i hear people talking about impala rims, i like the look of them, yes i know, it'll look like everyone else'* but i don't have, nor will i ever have, the money to drop on a decent set of aftermarket rims. Impala rims seem like a good, non-budget breaker, selection, is there a specific year that the rims fit on a bonneville? and is there and mods needed to fit them? any help would be appreciated.

possibly the 94 or 95 rims?

the bolt pattern is 5*115 with a 40-42mm positive offset.

I would suspect those would have a 4.5 inch or 114.3mm pattern, not close enough to use. There should be someone who knows somewhere on the internet, maybe try Google?

i've been trying all night, there'* a car in the auto trader that looks like it has the same rims as the 94 or 95. the bolt patterns i've come up with for the bonneville have all been for 14X16 (not specifying if it'* the SSE or not, i thought it made a difference, maybe not), which i do not have, i beleive i have 16X8 (not too sure, only got the car a few weeks back) which is the same as the impala ss (16X8, 5X127, low offset) so i'm just confused as it might change because it'* the SSE model


Here'* the link to the Bonneville with the rims, yes i know it'* an 88 but the bolt pattern i have found is for 87 and on

if you could clearify and send me in the right direction that'd be great because i'm pretty confused

16x7 factory rims for 1990 SE are on 115 mm bolt circle and 46 mm offset (cast in back of wheel). Offset will change with rim width and aftermarket 16x7s with 38 mm offset are about a 1/2" further out (increased track).

My experience is that 225x60x16s on factory 16x7x46 rims will just clear everything (main clearance issue is on front wheels at full steering lock).

Chrysler uses 5x4.5" (114.3 mm) which I have heard some claim will fit but I prefer wheels with the right pattern.

Keep in mind that GM wheels register on the hub (lug nuts just hold in place) & do not know if the Chrysler hub is the same size.

I think that newer impala wheels will fit. I have seen the 16" 5 star ones with the chev logo on the center cap on an 89 in the Auto Trader (local used car mag)

Try here.

120.7 mm = 4 3/4" (old GM RWD pattern)
127 mm = 5" (Old GM Large Car RWD pattern)

In general the current FWD use either
5x100 mm (small and medium size cars)
5x115 mm (large cars. Yes, Virginia, the Bonneville is a "large" car.)
