Are the Solstice rims the same as the GTP sedan rims?

If they are then all of us looking for winter rubber may be in business - see the last post for the website info.

No, they are not the same wheel.

The solstice features the same bolt pattern, 5x110mm, butt a higher offest @ 55mm. Basically the solstice wheels would stick 1" farther in than the stock 7" wide wheels at 41mm (while still being about same position on the outside) and would probably impact the struts, etc. Spacers may work, but would probably require new lugs.

However, I don't know how that will help - seeing as the solstice wheels, if you can find them, will be available at a PREMIUM most likely, and any aftermarket wheels will be designed around the higher offset.

Winter rubber isn't a hard thing to come by if you get new wheels to begin with. If you're considering solstice wheels, then certainly some cheap 17" wheels (like sport edition fox2s for under $100) with winter or A/S rubber would be still cheaper.

Additionally, the Solstice has Eagle RSAs, certainlly not any improvement over the LS2s...

miscreant,

Thanks for the info. The rubber is not what I'm worried about. It's the rim. I need 17" steel rims - but no one seems to have them in a 5x110 with around 38 offset. Apparently, the 1994 Saab 900 has similar wheels - however, they are $1720 CDN plus tax (around $2K all in). That is ridiculous for winter tires.

I'll keep looking.

Like I said, probably the best thing to do is get some decent Sport Edition rims for $90 from Tirerack with 17" winters mounted on them. Probably the cheapest thing right now.

Saab 9-3 and 9-5 wheels also fit for the most part, but finding 17" STEEL wheels is almost impossible. I don't know of any car that ever had 17" steel wheels.

Just so everyone knows. The GTP sedan and coupe have DIFFERENT bolt patterns. I'm not sure what Pontiac was thinking on that one.

Um, no they don't. Both are 5x110mm. They use the exact same wheels in fact.

They took off my wheels a couple of days ago - mechanic said they were 114.
Mechanic was wrong. :D

yup - sure was. Another guy just called me - they found rims for me - 16". Now we just have to see if they'll fit over the roters.

I'll keep you posted.

Let us know (I'm sure you will). What kind of 16"s are they (from what car?).

Someone posted earlier that "all g6's have the same bolt patter." That may be true but not all G6 rims are interchangeable. The GT and GTP are the same however the base and V6 aren't. Hence the problem, we can't take the 16's off a V6 and use them as snow on my car - they are different.

Anyway, the Sales Manager has been in touch with GM to tell them not to be so stupid in the future. Why would a line up of cars have different bolt patters? It seems to me that none of snow tire issues would be issues if they had used some foresight and made them all the same.

I'm sure you have something to say about that.

Are you serious??

I was going to ask if I could possible put the 17s on my V6. Will they work?

17's off the GT WILL work on the standard V6 model, as a replacement for the 16" steel wheels.

I have a set on my car now. No noticeable speedometer difference either. Ride is a tad rougher with the bigger, lower profile tires, but the Conti rubber handles a LOT better than the Uniroyal compound. Despite the handling in crease, I still can't wait to replace the Conti's with an agressive Bridgestone in the spring.

What is the overall diameter of the 17 GTs vs the 16 V6? I would have thought they would be the same *thus no difference on the speedo* anyone know?

Tirerack.com says the Conti 225/50 x 17 is 25.9" tall, with a rev per mile of 803. Tirerack doesn't list the matching specs for the 16" Uniroyal but I can tell you that the ones removed from my G are 26.5" tall. And I think I read on Uniroyal's website that they had a rev per mile of 796.

I think there's alot of eroneous information being spread to you.

First, what wheels were they supposedly off of? An Actual G6, or a Malibu? You must remember that the older malibu was not 5x110mm (was not an epsilon platform car) but 5x115mm. I had to correct a local dealership just the other day trying to sell me some 2001 malibu rims...

All G6s, the 4cyl, the 6cyl, the GT and the GTP, 2 or 4 door, have the EXACT SAME bolt pattern and offset requirements, period, end of story. The G6, the Malibu, the Opel Vectra and Signum, the Fiat Chroma, the Saturn Aura, and the Saab 9-3 are all built on the Epsilon Platform from GM, and subsequently ALL have 5x110mm and even ~40mm offset (the G6 features 41mm). If the 16" wheels did not fit on a GTP it's because of the larger brakes on the GTP (and GT, almost 1/2" larger), or they weren't G6 wheels to begin with.

As I stated in another thread somewhere (edit: here), Tirerack lists 16" wheels for the regular G6s, but for GT and GTP, they only list 17" wheels, which indicated to me that it's possible that most if not all 16" wheels will not fit over the bigger GT/GTP brakes. It may not even be a diameter problem, but rather the offest of the steel wheels makes them hit the side of the calipers (ie., not enough clearance. That's a disadvantage of having better brakes.

The Uniroyals are 26.1" tall according to Uniroyal.

The 4cyl, 6cyl, and GT models are all programmed at 26" tall tires, so swapping between wheels in these models requires no reprogramming of the PCM. However, the GTP models are programmed at 27" tall tires, so swapping between GTP and others will require reprogramming.

However, it looks like you can only swap down from GT to regular G6, not up, so keep that in mind.

Thanks for the intel. Perfect... Just need to find a set of 17s...
Tire rack has some cheap Sport Editions Fox2 17"s for under $100 each. Look decent, too - I've run them on my cars before. Nice small spokes, easy clean for winter.

EDIT: I think you mean your looking for 17"s to upgrade from 16"s? So disregard above :)

miscreant,

I said "That may be true but not all G6 rims are interchangeable." Then you go a spread erronous info yourself. The base V6 WILL NOT FIT THE OVERSIZE BRAKES of the performace G6's (GT and GTP.) Hence the problem we are all having.

Quit restating info to make yourself seem like king shit - it's annoying and not welcome.
