I know this has been discussed but I need some more clarification. I have done a searc and have not found the answers to my questions below.

I am looking a 18" wheels and as suggested:

Front: 18 x 8 - 245/45/18
Rear: 18 x 9 - 275/35/18

Questions:

1. Is this correct and will this work?
2. What offset is needed for each to prevent rubbing and to keep the tires within the wheelwell?
3. What is the "backside" dimension needed?

Thanks.

Hi. I own an 05 GTO and have the optional OEM 18 inch wheels. I went to my local Goodyear dealer last week and wanted to put on some Dunlop Sport 9000 275/35ZR 18's in the rear. The tire was to wide for the rim. The tech showed me and the rim just went right through the tire. I think the only way is to buy aftermarket rims. I was bummed. The stock 235/40's are okay, they are a little skinny for my taste. I agree on your plans for those tire size on your car. It would look so KILLER!!! :D

Try here.

They have a whole forum on aftermarket wheels and tires for our Goats.

G'luck.

(I've looked at hundreds of options for aftermarket wheels but none that makes me want to rid of my stocker 18"s)

I've never had good luck with aftermarket wheels for some reason. I just had my stock 17's chromed and they looked outstanding.

I am thinking about doing that as well. I am finding that there are not as many wheel that have our offset and bolt pattern as I thought and I can not find I really like.

Vette Wheels

My original plan was to put replica C5 or Z06 wheels on the Goat. But there were to many variables as far as sizing, etc. to even mess with.

Then again, when I look at my Goat, I realize there's a reason I waited an extra month for my OEM 18 option.

Discount tire is telling me that 245/40/18 is the largest tire that the GTO can handle on an 18 x8 rim is this true or can a 245/45/18 work without rubbing issues?

245/40's are the largest! They measure 25.7" tall and 10.9" wide mounted, this is the largest on stock 18's. :cheers

Thanks. Looking at getting BF Goodrich Sport tires. Had a question though...have any of you tried the Dunlop FM901s or the Cooper Zeon 2XPs? Both of those were in my group of choices as well.

I went with ROH 18x8, and 18x9 42mm, and 50mm offsets.BFG g-force KDW 245/40/18 front. BFG drag radial 275/35/18 rear. drove around 10 miles and the rear rubbed a little bit. So I had my fenders rolled now I have no issues at all. These tires won't break loose at all, unless you dump the clutch.

Hi!

I need information, what kind of wheels are possible install from new GTO? I mean, 5 - bolt wheels?

I´m from scandinavia and here ise a wery required to use in winter good tires and maby other wheels too. Maby 15 - 16 inch wheels. The winter tires are lot higher profile ex. 225/65/16 (maby even 225/70/15) or smth. But I don´t know, have the brakes enough room to put 15-16 inch wheels to GTO.

My brand new GTO will arrive in December. :) Delivery takes 1-2 months.

OK

Anyway, :cheers
