They fit just fine in the back.

 

got any pics?

 

Ill take some when i get home im out of town right now.

 

cool. thanks Rocks.
btw, are u running spacers or any drop?

 

The rear wheels on the 06 models are 18x8.5 arent they? Ive seen people put a 275 on the old 18x8 rear wheels.

 

I bet you have. But that's not a smart idea in either case. The max of the 8" wheel should be a 255 cross section tire and a 265 for an 8.5" wheel. A 275 width 40 or 35 series is best left to a 9" or better yet a 9.5" wheel.

Well whats funny if you measure it from the outside of the rim before it goes on the balancing machine it is 9 inches, its just a tiny bulge.

 

So on my 06 with 18x8.5 rears I can safely fit 265? What would the height be? 40

 

Yep, it would. 265/40/18.

Thanks Lou, now I just need to decide if I want the NISMO wheels or stick with stock.

 

Nismo's are a whole different ball game BTW, I run 18" Nismos on my "G".

If 265 is a good fit for the '06 OEM 18x8.5 rear, what's the recommended tire size for the OEM 18x8 front? 245?

 

245/40/18 front would work out fine. Rears can stay with stock 245/45 or 255/45/18s. With the wider tire in front, understeer would be reduced for more neutral handling.

Agree. Some members will tell you want is safe, and others what is possible. Its your decision.

 

275s work GREAT on the stock 8.5" wide rims. They don't look that "pooched" at all.

 

you guys know if 245/45/17 will fit on the 05 base model? stock is 235/50/17 on rear and 225/50/17 on front. im going to put the rear ones on front and 245/45/17 on back on stock rims

 

so anyone know??

 

What's the width of your 17" rims? Are they 17x7.5 & 17x8?

 

yup thats right

 

255/45/17 on stock rears fit just fine.
