: tires and rims...

any clue what bolt pattern are on the WS6? or if these will fit my 98 catera with minor mods?


I have always loved them...:alchi:

I don't see how. The bolt patterns aren't even close. The Firebird offset is greater but it'll take actuall measurements to tell if there are clearance problems. My wheels have +40mm offset but the Catera will handle +/-5mm. I also have 25mm spacers on the rear but none on the front. The wheel specs are from TireRack.com

CORRECTION:It seems the Pontiac bolt pattern is expressed in a radius. The Catera pattern is expressed by the distance between opposite bolts. Another site lists the Firebird pattern as 5x120.7mm (http://www.discountedwheelwarehouse.com/Pontiac___Vehicle_Bolt_Pattern_Reference.cfm)

2002 Pontiac Firebird
Bolt Pattern: 5x4.75 inch radius (5x120.7mm)
Offset: 50mm
Rec. Tire Size: 275/40-17

1998 Cadillac Catera
Bolt Patern: 5x110mm
Offset: 40mm
Rec. Tire Size: 235/45-17

? I guess Im way off, I thought the Catera was 5X115 Bolt Pattern? Same as the Chevy cobalt,HHR,Aurora,Grand Prix,And others... Those Wheels were listed as 5x115 by the seller when asked... Not sure on the off set but they would look great and 275 should be more grip than a guy could ask for.

5X110? Is this the final word on the Catera? I will go with that if some of the powers that be here say so.

Well if anyone wants any wheel info... i got some...

Catera wheels are 5/110mm bolt pattern with a 39mm offset for the 17x7.5" wheels... also the Inner bore diam... is 65.1mm... if the wheel doesnt match that you will need hubcentric adapters which go from the wheel diam to 65.1mm in order to properly distribute the load on the hub...

I have 2 sets of wheels that I will be looking to sell soon if anyone is interested let me know...
1st set is Catera Sport wheels, preped and waiting for some free time for some fresh paint, they had some scratches on the surface and I decided to fix them up and paint them as a winter set but now I have changed my mind...
Price is negotiable...

2nd set is a 18x8 GM wheels that were used to debut the Solstice/Sky platform... they had tires on but the one set that I got never saw the road or a car for that matter they were more for a show piece... so they are brand new. They are forged and extremely light, around 18lbs/pc 10spoke... I think they have a 55mm offset so you will need DRA spacers to fit them... but they will probably look sick on anyones car...

here is a pic...

thanks, what kinda price are you looking at for each?

03-27-08, 10:27 AM
Well I am not sure as to what these cost new but I talked to many people and they said these should sell for a min of 150/pop, Forged wheels are expensive apparently... the only problem as I said the Offset is too big for our cars.. and you will need the DRA spacers to bring them to spec.

to respond to gunther the catera is same as the hhr cobalt SS only g5 5 lug aura, g6 and 05 malibu (new body not classic) but these cars are a 5x110 as was mentioned. the 5x115 was the comman gm pattern, but not so much right now.. just the full/large cars still carry it.

I belive the solstice and sky are the 5x110 as mentioned. I have considered a set of cobalt ss rims for my catera.. but the slots are larger openings and I think i prefer to see more metal than air!

correct 17" on a catera is 235 45 17 or 225 50 17 mis sizing your tires will mess up your spedometer and milage acuracy. when I got my catera the dumb nuts had 215 45 17 and my milage was adding 10% more than I was driving.. so who knows how long they were on the car..

Does anyone have 18" rims on there Cats? I would like to see some pics.

Reason I ask, is I found a set of 18" rims that I like, but was really wanting 17's.

06-14-10, 08:06 PM
the 18s will be fine.. go for it.. 17s are becoming obsolete. I had a bitch of a time finding 17 with 5x110 pattern that looked decent.. there are tons of 18s and 19s, but I was tring to use the tires I had.

I think tirerack has a clearance sale on some rims right now.. go look they may be sold.. but check it out. they have a thing where you can kinda see them on the car.

As long as you size the tire correctly any size is going to look good! I just bought 17 cobalt ss chromes but I gotta get the tires on and as I leared a 8mm spacer to have them sit at same width the catera sport rims sit at.

good lcuk!
